    To examine the association of cognitive function, age, and hearing loss with clinically assessed hearing aid benefit in older hearing-impaired persons. Hearing aid benefit was assessed using objective measures regarding speech recognition in quiet and noisy environments as well as a subjective measure reflecting everyday situations captured using a standardized questionnaire. A broad range of general cognitive functions such as attention, memory, and intelligence were determined using different neuropsychological tests. Linear regression analyses were conducted with the outcome of the neuropsychological tests as well as age and hearing loss as independent variables and the benefit measures as dependent variables. Thirty experienced older hearing aid users with typical age-related hearing impairment participated. Most of the benefit measures revealed that the participants obtained significant improvement with their hearing aids. Regression models showed a significant relationship between a fluid intelligence measure and objective hearing aid benefit. When individual hearing thresholds were considered as an additional independent variable, hearing loss was the only significant contributor to the benefit models. Lower cognitive capacity - as determined by the fluid intelligence measure - was significantly associated with greater hearing loss. Subjective benefit could not be predicted by any of the variables considered. The present study does not give evidence that hearing aid benefit is critically associated with cognitive function in experienced hearing aid users. However, it was found that lower fluid intelligence scores were related to higher hearing thresholds. Since greater hearing loss was associated with a greater objective benefit, these results strongly support the advice of using hearing aids regardless of age and cognitive function to counter hearing loss and the adverse effects of age-related hearing impairment. Still, individual cognitive capacity might

    Hearing loss is one of the most disabling impairments. Using a hearing aid as an attempt to improve the hearing problem can positively affect the quality of life for these people. This research was aimed to assess satisfaction of hearing impaired patients with their hearing aids regarding the employed technology and style. This descriptive-analytic cross-sectional research was conducted on 187 subjects with hearing loss who were using a hearing aid. The subjects were over 18 years of age and were using a hearing aid for at least 6 months. The Persian version of Satisfaction with Amplification in Daily Life (SADL) questionnaire was the instrument which was used for assessing satisfaction with the hearing aid. Cronbach's alpha was calculated to be 0.80 for instrument reliability. A significant difference was observed among satisfaction subscales' mean scores with hearing aid technology. Also a significant difference was observed between the total satisfaction score and the hearing aid model. With respect to the analysis of satisfaction with the hearing aid and its style, cost and services was the only subscale which showed a significant difference (P=0.005). Respondents using hearing aids with different technology and style were estimated to be quite satisfied. Training audiologists in using more appropriate and fitting hearing aids in addition to using self-reporting questionnaires like SADL for estimating patients' social condition and participation in their life can essentially change their disability condition and countervail their hearing loss.

    Conducting assessment with individuals with physical disability, visual impairment or blindness, and hearing impairment or deafness poses significant challenges for the neuropsychologist. Although standards for psychological testing have been devised to address assessment of persons with disabilities, little research has been conducted to validate neuropsychological test accommodation and modification practices that deviate from standard test administration or to develop test parameters and interpretive guidelines specifically for persons with different physical or sensory disabilities. This paper reviews issues pertaining to neuropsychological test selection and administration, common accommodation and modification practices, test development and validation, and disability-related factors that influence interpretation of test results. Systematic research is needed to develop methodological parameters for testing and to ensure reliable and valid neuropsychological assessment practices for individuals with physical or sensory disabilities.

    Within the Lower Saxony Research Network Design of Environments for Ageing (GAL), a personal activity and household assistant (PAHA), an ambient reminder system, has been developed. One of its central output modality to interact with the user is sound. The study presented here evaluated three different system technologies for sound reproduction using up to five loudspeakers, including the "phantom source" concept. Moreover, a technology for hearing loss compensation for the mostly older users of the PAHA was implemented and evaluated. Evaluation experiments with 21 normal hearing and hearing impaired test subjects were carried out. The results show that after direct comparison of the sound presentation concepts, the presentation by the single TV speaker was most preferred, whereas the phantom source concept got the highest acceptance ratings as far as the general concept is concerned. The localization accuracy of the phantom source concept was good as long as the exact listening position was known to the algorithm and speech stimuli were used. Most subjects preferred the original signals over the pre-processed, dynamic-compressed signals, although processed speech was often described as being clearer.

    Service dogs help persons with mobility impairments by retrieving items and performing other tasks. Hearing dogs alert persons with hearing impairments to environmental sounds. We conducted a pre-post, wait list-controlled pilot study to assess the impact of the dogs on the lives of recipients. Participants were recruited through two assistance dog training organizations and completed an initial questionnaire packet. The Experimental group completed another packet 6 months after receiving a dog. The Control group completed a second packet 6 months after the initial data collection. On average, dog recipients were very satisfied with their assistance dogs. Both service and hearing dog recipients reduced their dependence on other persons. Service dog recipients reduced hours of paid assistance. No other significant change occurred in various standardized outcome measures. Assistance dogs had a major positive impact on the lives of recipients. More appropriate measurement instruments are needed to capture the impact of these dogs.

    Older patients represent the majority of hearing-aid users. The needs of elderly, hearing-impaired subjects are not entirely identified. The present study aims to determine the importance of fundamental hearing-aid attributes and to elicit the utility of associated hypothetical hearing aids for older patients. This was achieved using a questionnaire-based conjoint analysis--a decompositional approach to preference measurement offering a realistic study design. A random sample of 200 experienced hearing-aid users participated in the study. Though three out of the six examined attributes revealed age-related dependencies, the only significant effect was found for the attribute "handling", which was considerably more important for older than younger hearing-aid users. A trend of decreasing importance of speech intelligibility in noise and increasing significance of speech in quiet was observed for subjects older than 70 years. In general, the utility of various hypothetical hearing aids was similar for older and younger subjects. Apart from the attribute "handling", older and younger subjects have comparable needs regarding hearing-aid features. On the basis of the examined attributes, there is no requirement for hearing aids designed specifically for elderly hearing-aid users, provided that ergonomic features are considered and the benefits of modern technology are made fully available for older patients.

    : The goals of the present study were twofold: in the first part, the prevalence and profile of hearing disability in healthy, middle-aged persons were determined by the speech, spatial, and qualities of hearing scale (SSQ). In the second part of this study, the number of SSQ items was reduced to five to make this questionnaire available for routine usage in clinical settings and for screening purposes. : SSQ responses derived from 103 normal-hearing 18- to 25-year-old persons were compared with the SSQ responses of 24 clinically normal-hearing (all thresholds between 125 and 8000 Hz ≤25 dB HL) and 109 healthy, 55- to 65-year-old persons with age-related hearing impairment to determine the prevalence and profile of hearing disability. The 45 items of the SSQ were reduced to five by cluster analyses and binary logistic regression analyses. The robustness of this five-item version (SSQ5) was determined in three control populations: an adult 25- to 55-year-old population (n = 159), an ENT-patient population (n = 60), and a population of hearing aid candidates (n = 50). The feasibility of the SSQ5 for screening was compared with the feasibility of the simple question "Do you have hearing loss?" by determining, respectively, the sensitivity, specificity, and maximum achievable discriminatory power for predicting hearing status according to speech-in-noise performance. : Prevalence numbers showed data of healthy, middle-aged persons with significant disability, despite minimal impairment (25%) versus data of middle-aged persons with significant impairment and nevertheless, minimal disability (61%). The profile of hearing disability seemed similar in all normal-hearing and hearing-impaired subgroups (i.e., most problems with understanding speech especially in noise conditions, and least problems with sound quality). Compared with the single question: "Do you have hearing loss?" the use of the SSQ5 had 37% more maximum discriminatory power for determining hearing status

    Annoyance ratings in speech intelligibility tests at 45 dB(A) and 55 dB(A) traffic noise were investigated in a laboratory study. Subjects were chosen according to their hearing acuity to be representative of 70-year-old men and women, and of noise-induced hearing losses typical for a great number of industrial workers. These groups were compared with normal hearing subjects of the same sex and, when possible, the same age. The subjects rated their annoyance on an open 100 mm scale. Significant correlations were found between annoyance expressed in millimetres and speech intelligibility in percent when all subjects were taken as one sample. Speech intelligibility was also calculated from physical measurements of speech and noise by using the articulation index method. Observed and calculated speech intelligibility scores are compared and discussed. Also treated is the estimation of annoyance by traffic noise at moderate noise levels via speech intelligibility scores.

    When deafened adults recover some hearing after receiving a cochlear implant, numerous changes in their speech occur at both phonemic and suprasegmental levels. If a change toward normative values is observed for some phonemic parameter, it may be attributed to the restored hearing; however, it may be a by-product of a suprasegmental change. Consistent with results reported for speakers with normal hearing, Lane et al. [J. Acoust. Soc. Am. 98, 3096-3106 (1995)] observed in implant users that VOT varies approximately linearly with syllable duration. Therefore, in comparing pre- and postimplant measures of VOT in five speakers, each token's VOT was adjusted for the change in syllable duration of that token relative to the mean syllable duration in a baseline session (called VOTc). Preimplant, the deaf speakers characteristically uttered plosives with abnormally short VOTc. With some hearing restored, four of the five lengthened VOTc. Changes in voiced plosives' VOTc with restored hearing were correlated with changes in SPL. Some of the reliable VOTc increases that were not correlated with SPL may have been caused by auditory validation of an internal model for phoneme production. Recent studies of VOT in hearing-impaired speakers will be reviewed in this light. [Work supported by NIDCD, NIH.

    The social anthropology of mild hearing loss is gradually being accepted, as it affects both children and adults. With this comes the understanding that effective aural communication requires adequate sound sources and a good transmission medium as well as good hearing. If the first two conditions are met, much hearing disability might be avoided without resorting to a hearing aid. A plea is made for better accessibility for the hearing impaired by improving environmental conditions for acoustic signals, especially speech.

    Previous studies have demonstrated that successful listening with advanced signal processing in digital hearing aids is associated with individual cognitive capacity, particularly working memory capacity (WMC). This study aimed to examine the relationship between cognitive abilities (cognitive processing speed and WMC) and individual listeners’ responses to digital signal processing settings in adverse listening conditions. A total of 194 native Swedish speakers (83 women and 111 men), aged 33–80 years (mean = 60.75 years, SD = 8.89), with bilateral, symmetrical mild to moderate sensorineural hearing loss who had completed a lexical decision speed test (measuring cognitive processing speed) and semantic word-pair span test (SWPST, capturing WMC) participated in this study. The Hagerman test (capturing speech recognition in noise) was conducted using an experimental hearing aid with three digital signal processing settings: (1) linear amplification without noise reduction (NoP), (2) linear amplification with noise reduction (NR), and (3) non-linear amplification without NR (“fast-acting compression”). The results showed that cognitive processing speed was a better predictor of speech intelligibility in noise, regardless of the types of signal processing algorithms used. That is, there was a stronger association between cognitive processing speed and NR outcomes and fast-acting compression outcomes (in steady state noise). We observed a weaker relationship between working memory and NR, but WMC did not relate to fast-acting compression. WMC was a relatively weaker predictor of speech intelligibility in noise. These findings might have been different if the participants had been provided with training and or allowed to acclimatize to binary masking noise reduction or fast-acting compression. PMID:28861009

    A binaural dichotic presentation scheme for reducing the effect of increased spectral masking in persons with bilateral sensorineural loss, using spectral splitting with complementary comb filters based on auditory critical bands, has been earlier reported [Cheeran et al., J. Acoust. Soc. Am. 110, 2705 (2001)]. The 256-coefficient linear phase FIR filters designed using frequency sampling technique had transition crossovers adjusted within -6 to -4 dB for perceptual balance, and had 78-117 Hz transition, 1 dB passband ripple, and 30 dB stopband attenuation. We evaluated the scheme by conducting listening tests on 5 normal hearing subjects with simulated loss, using a closed set identification of 12 vowel-consonant-vowel syllables. Based on significant improvement, further tests were conducted on 5 hearing-impaired persons with moderate bilateral sensorineural loss. Significant improvement in response time, recognition scores, and transmission of consonantal features, particularly place and duration, was obtained, indicating reduction in the effect of spectral masking. In order to partly compensate for frequency dependent hearing threshold shifts, a pair of filters with frequency response adjusted within a 6 dB range, based on the audiogram for the corresponding ear, was cascaded with the comb filters. These filters resulted in additional improvement, particularly for persons with relatively uniform loss.

  1. Couples' attributions about behaviours modulated by hearing impairment: links with relationship satisfaction.

    The aim of the study was to examine the link between the nature of attributions made by partners about behaviours modulated by hearing loss, and overall relationship satisfaction. Forty-three hearing-impaired males and 23 hearing-impaired females together with their partners, each rated the hearing-impaired person's hearing ability, their own relationship satisfaction, and their attributions for hypothetical behaviours typically associated with impaired hearing. Attributions covered perceived causes of behaviour and perceived responsibility. The extent to which the behaviours typically associated with impaired hearing, were attributed to personal causes and responsibilities was inversely correlated with relationship satisfaction. Female partners (more than male partners, or females with impaired hearing) made attributions that accentuated the unpleasant implications of behaviour. Where attributions and ratings of degree of hearing loss were greater in partners than in the person with the loss, relationship satisfaction was lower. Implications for rehabilitation counselling are discussed.

    Many older people believe sensory problems are inevitably, a part of growing old, and avoid assessment and help. Such problems are often also overlooked by health professionals. The aim of this study was to find the prevalence of hearing and vision impairment and their associations with loss of instrumental activities in daily living (IADL) and risk of falling in patients aged 75 years or older, admitted to a medical ward in an acute hospital in each of the five Nordic countries. The Minimum Data Set for Acute Care was used for data collection in 770 patients. Premorbid data, admission data and history of falls over 3 months were obtained on admission by interview and observation. Hearing impairment was present if the patient required a quiet setting to be able to hear normal speech. Vision impairment was defined as unable to read regular print in a newspaper. Bivariate and logistic regression analyses were performed. Forty-eight per cent of the patients had a hearing impairment, 32.3% had vision impairment and 20.1% had both. Hearing impairment was associated with falling but not in the logistic regression model. Hearing and vision impairment were associated with loss of IADL but only combined impairment was independently. Hearing and vision impairments were frequent among older patients in the medical wards. Falling was associated with hearing loss and IADL loss with hearing, vision and combined impairments. Sensory loss was also associated with fear of falling. It is recommended routinely to screen sensory functions in older patients in a medical setting. Intervention studies are needed to determine whether improvements in hearing and vision can prevent falls and further loss of function in this patient population.

    In recent years some studies could show that besides the negative effects of stressful encounters resulting from disorders and handicaps, positive experiences can also be made. The aim of this study was to determine which strategies can help persons with hearing impairments to gain positive experiences. A questionnaire in the German language consisting of the Trier Personality Inventory and a German translation of a questionnaire designed to measure the positive experiences in life with acquired hearing impairment was distributed to persons with acquired hearing impairment, who were recruited from hearing aid audiologists and ear nose and throat physicians. Persons with hearing impairments showed no differences to the general population with respect to their personality profile. Positive experiences are significantly more common by successful communication behavior than by other strategies. Successful communication helps persons with hearing impairments to gain positive experiences.

  10. Cortical Auditory Evoked Potentials in (Un)aided Normal-Hearing and Hearing-Impaired Adults

    Van Dun, Bram; Kania, Anna; Dillon, Harvey

    2016-01-01

    Cortical auditory evoked potentials (CAEPs) are influenced by the characteristics of the stimulus, including level and hearing aid gain. Previous studies have measured CAEPs aided and unaided in individuals with normal hearing. There is a significant difference between providing amplification to a person with normal hearing and a person with hearing loss. This study investigated this difference and the effects of stimulus signal-to-noise ratio (SNR) and audibility on the CAEP amplitude in a population with hearing loss. Twelve normal-hearing participants and 12 participants with a hearing loss participated in this study. Three speech sounds—/m/, /g/, and /t/—were presented in the free field. Unaided stimuli were presented at 55, 65, and 75 dB sound pressure level (SPL) and aided stimuli at 55 dB SPL with three different gains in steps of 10 dB. CAEPs were recorded and their amplitudes analyzed. Stimulus SNRs and audibility were determined. No significant effect of stimulus level or hearing aid gain was found in normal hearers. Conversely, a significant effect was found in hearing-impaired individuals. Audibility of the signal, which in some cases is determined by the signal level relative to threshold and in other cases by the SNR, is the dominant factor explaining changes in CAEP amplitude. CAEPs can potentially be used to assess the effects of hearing aid gain in hearing-impaired users. PMID:27587919

  11. Apoptosis in acquired and genetic hearing impairment

    PubMed Central

    2012-01-01

    Apoptosis is an important physiological process. Normally, a healthy cell maintains a delicate balance between pro- and anti-apoptotic factors, allowing it to live and proliferate. It is thus not surprising that disturbance of this delicate balance may result in disease. It is a well known fact that apoptosis also contributes to several acquired forms of hearing impairment. Noise-induced hearing loss is the result of prolonged exposure to excessive noise, triggering apoptosis in terminally differentiated sensory hair cells. Moreover, hearing loss caused by the use of therapeutic drugs such as aminoglycoside antibiotics and cisplatin potentially may result in the activation of apoptosis in sensory hair cells leading to hearing loss due to the “ototoxicity” of the drugs. Finally, apoptosis is a key contributor to the development of presbycusis, age-related hearing loss. Recently, several mutations in apoptosis genes were identified as the cause of monogenic hearing impairment. These genes are TJP2, DFNA5 and MSRB3. This implies that apoptosis not only contributes to the pathology of acquired forms of hearing impairment, but also to genetic hearing impairment as well. We believe that these genes constitute a new functional class within the hearing loss field. Here, the contribution of apoptosis in the pathology of both acquired and genetic hearing impairment is reviewed. PMID:21782914

    Mumps was reported to be a cause of hearing loss in 259 persons from a sample of 43,946 students enrolled in special educational programs for the hearing impaired. Males and young children appear to be more prone to deafening by mumps, and there may be a relationship between age of onset and degree of hearing loss. Overall, those deafened by mumps appear to have characteristics quite different from those of children deafened by other causes.

    Failure to recognize the presence of a hearing impairment in early childhood can severely harm the development of the child. A differentiation is made between sound conduction deafness and sensorineural.deafness. The former may be temporary or permanent. The latter may be inherited or acquired. Inherited sensorineural deafness occurs within the framework of syndromes, or may be monosymptomatic. Acquired sensorineural deafness may occur prenatally, perinatally or postnatally. A range of subjective and objective audiological tests is available, which, depending on the age and state of developmental of the child, can be used in combination. Cases of syndromal deafness are investigated on an interdisciplinary basis and involve the pediatrician, geneticist, laboratory physician and radiologist.

    Congenital cytomegalovirus (cCMV) is the most common non-genetic cause of childhood sensorineural hearing loss. Antiviral treatment has been shown to prevent hearing deterioration in these infants. However, studies focused on infants with hearing impairment at birth and on the specific degree of impairment and further improvement or deterioration are lacking. To investigate the relationship between hearing status at birth and any change in hearing status at the end of a prolonged follow-up period, after receiving 12 months of antiviral treatment in children born with hearing impairment due to congenital cCMV. Clinical, laboratory, radiological and audiological data of all infants with cCMV infection followed in our centre between 2005 and 2013 were reviewed. Treatment with antiviral medication for hearing impairment found during the neonatal period was12 months of gan/valganciclovir. Hearing studies were performed only on infants who had been followed up for more than 1 year after treatment. Hearing impairment at birth was found in 54 (36.2%) of the 149 infants diagnosed with symptomatic cCMV, and found in 77 affected ears; unilateral in 31 (57.4%) and bilateral in 23 (42.6%). After 1 year of antiviral treatment and a long-term follow-up of the 77 affected ears at baseline, 50 (64.9%) had improved, 22 (28.6%) remained unchanged and 5 (6.5%) had deteriorated. Most improved ears (38/50=76%) returned to normal hearing. Improvement was most likely to occur in infants born with mild or moderate hearing loss and less in those with severe impairment. We found that infants born with cCMV and hearing impairment, receiving 12 months of antiviral treatment, showed significant improvement in hearing status. The probability of hearing improvement seems inversely related to the severity of the impairment at birth. Published by the BMJ Publishing Group Limited.

  15. Effects of noise reduction on speech intelligibility, perceived listening effort, and personal preference in hearing-impaired listeners.

    This study evaluates the perceptual effects of single-microphone noise reduction in hearing aids. Twenty subjects with moderate sensorineural hearing loss listened to speech in babble noise processed via noise reduction from three different linearly fitted hearing aids. Subjects performed (a) speech-intelligibility tests, (b) listening-effort ratings, and (c) paired-comparison ratings on noise annoyance, speech naturalness, and overall preference. The perceptual effects of noise reduction differ between hearing aids. The results agree well with those of normal-hearing listeners in a previous study. None of the noise-reduction algorithms improved speech intelligibility, but all reduced the annoyance of noise. The noise reduction that scored best with respect to noise annoyance and preference had the worst intelligibility scores. The trade-off between intelligibility and listening comfort shows that preference measurements might be useful in addition to intelligibility measurements in the selection of noise reduction. Additionally, this trade-off should be taken into consideration to create realistic expectations in hearing-aid users.

    Noisy classrooms have been shown to induce among students patterns of interaction similar to those used by hearing impaired people [W. H. McKellin et al., GURT (2003)]. In this research, the speech of children in a noisy classroom setting was investigated to determine if noisy classrooms have an effect on students' speech. Audio recordings were made of the speech of students during group work in their regular classrooms (grades 1-7), and of the speech of the same students in a sound booth. Noise level readings in the classrooms were also recorded. Each student's noisy and quiet environment speech samples were acoustically analyzed for prosodic and segmental properties (f0, pitch range, pitch variation, phoneme duration, vowel formants), and compared. The analysis showed that the students' speech in the noisy classrooms had characteristics of the speech of hearing-impaired persons [e.g., R. O'Halpin, Clin. Ling. and Phon. 15, 529-550 (2001)]. Some educational implications of our findings were identified. [Work supported by the Peter Wall Institute for Advanced Studies, University of British Columbia.

    Objective: Our aim was to explore the usage of individualized computer models to simulate hearing loss based on detailed psychophysical assessment and to offer hypothetical diagnoses of the underlying pathology. Individualized computer models of normal and impaired hearing were constructed and evaluated using the psychophysical data obtained from human listeners. Computer models of impaired hearing were generated to reflect the hypothesized underlying pathology (e.g. dead regions, outer hair cell dysfunction, or reductions in endocochlear potential). These models were evaluated in terms of their ability to replicate the original patient data. Auditory profiles were measured for two normal and five hearing-impaired listeners using a battery of three psychophysical tests (absolute thresholds, frequency selectivity, and compression). The individualized computer models were found to match the data. Useful fits to the impaired profiles could be obtained by changing only a single parameter in the model of normal hearing. Sometimes, however, it was necessary to include an additional dead region. The creation of individualized computer models of hearing loss can be used to simulate auditory profiles of impaired listeners and suggest hypotheses concerning the underlying peripheral pathology.

    Objective Thyroid hormone is necessary for normal development of the auditory system. The aim of this study was to investigate the rate of hearing impairment in congenitally hypothyroid (CH) patients, and its relation with factors such as CH severity and age at starting treatment, during CH screening program in Isfahan. Methods Hearing acuity was assessed in two groups of children with (94 patients aged 4 months – 3 years) and without CH (450), between 2000-2006. Otoacostic emission (OAE) was performed by a two step method. After two tests without OAE signals bilaterally, they were referred for auditory brainstem response (ABR) test. Subjects with both OAE and ABR abnormal test results were considered to have hearing problem. Obtained data was compared in case and control group and also CH patients with and without hearing impairment. Findings Three (3.2%) of patients and 1 of control group (0.2%) were diagnosed with sensorineural hearing loss. The rate of hearing loss was not different significantly in two studied groups (P>0.05). There was no difference between age of starting treatment and first T4 and TSH level in CH patients with and without hearing loss (P>0.05). CH neonates with hearing impairment had thyroid dyshormonogenesis according to the follow up results. Conclusion The rate of hearing loss was low among our studied CH patients. It may be due to proper management of CH patients. In view of the fact that all CH neonates were dyshormonogentic and considering the relation between certain gene mutations and hearing impairment in CH patients, further studies with larger sample size, with regard to different etiologies of CH should be investigated to indicate the possible gene mutations related to hearing loss in CH.

    2007-04-01

    Hearing impairment is the most common sensorineural disorder in humans. Approximately one of thousand new-borns is affected by severe to profound deafness at birth or during early childhood. Genetic causes account for around half of these cases of prelingual hearing impairment and the remainder are attributed to environmental factors. Genetic causes of hearing impairment in combination with a syndrome as Usher, Pendred are distinguished from non-syndromic hearing impairment. In the last years a tremendous growth in the localisation and identification of genes for non-syndromic hereditary hearing impairment has evolved. It has become clear that these conditions are genetically extremely heterogeneous. Approximately 120 different gene loci associated with non syndromic hearing impairment have been identified. Presently 54 gene loci associated with autosomal dominant mode of inheritance and 67 gene loci with autosomal recessive mode of inheritance have been identified; 7 are X-chromosome linked and 4 mitochondrial. Of these, 19 genes have been characterised for autosomal dominant (DFNA), 20 for autosomal recessive (DFNB), and 2 for X-linked (DFN) disorders. These genes encode proteins of diverse functions, including transcription factors, cytoskeletal and extracellular matrix components, and ion channels. Despite this heterogeneity, up to 50 % of prelingual recessive non-syndromic deafness can be attributed to mutations in the GJB2 gene (Connexin-26, gap-junction protein). However, the diversity of genes and genetic loci implicated in hearing loss illustrates the complexity of the genetic basis of hearing. Knowing the gene and the function of its products helps understanding the mechanisms of hearing.

    A permanent, noise-induced hearing loss has doubly harmful effect on speech communications. First, the elevation in the threshold of hearing means that many speech sounds are too weak to be heard, and second, very intense speech sounds may appear to be distorted. The whole question of the impact of noise-induced hearing loss upon the impairments and handicaps experienced by people with such hearing losses was somewhat controversial partly because of the economic aspects of related practical noise control and workmen's compensation.

    1988-05-01

    This study examines the degree to which hearing-impaired children of hearing-impaired parents (HIP) demonstrate an advantage in their acquisition of signed and spoken English over hearing-impaired children of hearing parents (HP). A subset from the normative sample of the Grammatical Analysis of Elicited Language, 50 HIP children and 50 HP children, were matched in terms of their educational program, hearing level, and age. Results indicate that both groups had comparably poor expressive English language ability at 5 and 6 years of age. However, at age 7 and 8 HIP children demonstrated a significant linguistic advantage in both their spoken and signed English over HP children. Because the production of English by HIP children closely resembled that of orally educated hearing-impaired children of hearing parents, consistent language stimulation throughout the child's early years may be a critical factor in the development of English, regardless of the language or mode of expression.

    Previously suggested diagonal-steering algorithms for binaural hearing support devices have commonly assumed that the direction of the speech signal is known in advance, which is not always the case in many real circumstances. In this study, a new diagonal-steering-based binaural speech localization (BSL) algorithm is proposed, and the performances of the BSL algorithm and the binaural beamforming algorithm, which integrates the BSL and diagonal-steering algorithms, were evaluated using actual speech-in-noise signals in several simulated listening scenarios. Testing sounds were recorded in a KEMAR mannequin setup and two objective indices, improvements in signal-to-noise ratio (SNRi ) and segmental SNR (segSNRi ), were utilized for performance evaluation. Experimental results demonstrated that the accuracy of the BSL was in the 90-100% range when input SNR was -10 to +5 dB range. The average differences between the γ-adjusted and γ-fixed diagonal-steering algorithms (for -15 to +5 dB input SNR) in the talking in the restaurant scenario were 0.203-0.937 dB for SNRi and 0.052-0.437 dB for segSNRi , and in the listening while car driving scenario, the differences were 0.387-0.835 dB for SNRi and 0.259-1.175 dB for segSNRi . In addition, the average difference between the BSL-turned-on and the BSL-turned-off cases for the binaural beamforming algorithm in the listening while car driving scenario was 1.631-4.246 dB for SNRi and 0.574-2.784 dB for segSNRi . In all testing conditions, the γ-adjusted diagonal-steering and BSL algorithm improved the values of the indices more than the conventional algorithms. The binaural beamforming algorithm, which integrates the proposed BSL and diagonal-steering algorithm, is expected to improve the performance of the binaural hearing support devices in noisy situations.

  16. Oral health conditions and behaviors among hearing impaired and normal hearing college students at Ratchasuda College, Nakhon Pathom, Thailand.

    This study aimed to explore oral health and oral health related behaviors among hearing impaired and normal hearing students at Rachasuda College. The association between socioeconomic factors, hearing status, oral health behaviors, oral hygiene levels and dental caries status were also examined. The students filled out a self-administered questionnaire with assistance of a sign language video to obtain personal and behavior information. A total of 180 students, 83 normal hearing and 97 hearing impaired students completed the questionnaire and underwent an oral examination. The prevalences of caries were 53.6% and 50.6% among students with hearing impairment and normal hearing, respectively (p=0.354). After age stratification, the hearing impaired students aged 18-21 years had significantly less filled teeth (p=0.012), and those older than 21 years had less missing teeth due to caries than normal-hearing students (p=0.023). Poor oral hygiene was found in 51.8% and 42.2% of normal and hearing-impaired students, respectively (p=0.365). Caries status was significantly associated with maternal education level (OR 3.56; 95% CI: 1.52-8.32) and oral hygiene (OR 3.26; 95% CI: 1.64-6.45). The high prevalence of dental caries and poor oral hygiene among college students is alarming. Hearing impairment did not appear to affect the prevalences of these conditions compared to those with normal hearing. Oral health education tools need to be developed and utilized for both normal hearing and hearing impaired college students in Thailand.

    2009-12-01

    A concept and architecture of a personal communication system (PCS) is introduced that integrates audio communication and hearing support for the elderly and hearing-impaired through a personal hearing system (PHS). The concept envisions a central processor connected to audio headsets via a wireless body area network (WBAN). To demonstrate the concept, a prototype PCS is presented that is implemented on a netbook computer with a dedicated audio interface in combination with a mobile phone. The prototype can be used for field-testing possible applications and to reveal possibilities and limitations of the concept of integrating hearing support in consumer audio communication devices. It is shown that the prototype PCS can integrate hearing aid functionality, telephony, public announcement systems, and home entertainment. An exemplary binaural speech enhancement scheme that represents a large class of possible PHS processing schemes is shown to be compatible with the general concept. However, an analysis of hardware and software architectures shows that the implementation of a PCS on future advanced cell phone-like devices is challenging. Because of limitations in processing power, recoding of prototype implementations into fixed point arithmetic will be required and WBAN performance is still a limiting factor in terms of data rate and delay.

    This study examined strategies for initiating social interactions with peers, among 4 children with hearing impairment, aged 33 to 36 months, attending a special early education center or a regular kindergarten. The study investigated initiation type (related to partner's hearing status) and rates of initiation success/failure vis-a-vis hearing and deaf partners. Results revealed (a) more initiations in the regular program than in the special program; (b) in the special program, much more successful initiations toward children with hearing impairment than toward hearing children; (c) vocalization as the most frequent strategy used with both hearing and hearing-impaired partners; and (d) referential decisions about their initiations even among young children with hearing impairment (made by changing frequencies of various strategies according to partner's hearing status). The discussion addressed implications regarding integration of children with hearing impairment into regular educational settings.

    To determine the relationships between visual and hearing impairment and subsequent functional dependence and mortality among community-dwelling older persons. A Prospective, cohort study. Community-based. A total of 5444 men and women aged 55 to 74 years at baseline. Self-reported and measured visual impairment, self-reported and measured hearing impairment, self-reported and measured combined sensory impairment, 10-year mortality, and dependency in activities of daily living (ADL), instrumental ADL (IADL), and Rosow-Breslau (RB) function. In multiply-adjusted models, adjusting for length of follow-up, socio-demographic characteristics, and chronic conditions, only measured visual impairment was predictive of mortality. Measured visual impairment was also predictive of 10-year ADL and IADL dependence; measured hearing impairment was predictive of RB dependence. Self-reported visual impairment predicted functional impairment on all scales at 10 years, although self-reported hearing impairment predicted only subsequent RB dependence. Measured combined impairment was associated with the highest risk of 10-year functional dependence. Sensory impairment is predictive of subsequent functional impairment in older persons.

    2016-01-01

    Objectives: To better understand the potential impact of hearing impairment (HI) and hearing aid use on emotional vitality and mental health in older adults. Method: We investigated the cross-sectional association of HI with emotional vitality in 1,903 adults aged 76–85 years in the Health ABC study adjusted for demographic and cardiovascular risk factors. Hearing was defined by the speech frequency pure tone average (no impairment < 25 dB, mild impairment 25–40 dB, and moderate or greater impairment > 40 dB). Emotional vitality was defined as having a high sense of personal mastery, happiness, low depressive symptomatology, and low anxiety. Results: Compared with individuals with no HI, participants with moderate or greater HI had a 23% lower odds of emotional vitality (odds ratio [OR] = 0.77; 95% confidence interval [CI]: 0.59–0.99). Hearing aid use was not associated with better emotional vitality (OR = 0.98; 95% CI: 0.81–1.20). Discussion: HI is associated with lower odds of emotional vitality in older adults. Further studies are needed to examine the longitudinal impact of HI on mental health and well-being. PMID:26883806

    The effects of hearing impairment on the person with the impairment and on their significant others are pervasive and affect the quality of life for all involved. The effect of hearing impairment on significant others is known as a third-party disability. This study aimed to develop and psychometrically test a scale to measure the third-party disability experienced by spouses of older people with hearing impairment. The Significant Other Scale for Hearing Disability (SOS-HEAR) was based on results of a previous qualitative study investigating the effect of hearing impairment on a spouse's everyday life. Psychometric testing with 100 spouses was conducted using item analysis, Cronbach's alpha, factor analysis, and test-retest reliability. Principal components analysis identified six key underlying factors. A combined set of 27 items was found to be reliable (alpha = 0.94), with weighted kappa for items ranging from fair to very good. The SOS-HEAR is a brief, easy to administer instrument that has evidence of reliability and validity. The SOS-HEAR could serve as a means of identifying spouses of older people with hearing impairment in need of intervention, directed towards either the couple or the spouse alone.

    1990-12-01

    Training hearing-impaired persons in independent living skills has become a focus of education and rehabilitation programs for the hearing impaired. Yet, few programs and assessment instruments are designed to evaluate a person's potential for acquiring independent living skills. In this study, the Vineland Adaptive Behavior Scale was used to classify 118 hearing-impaired persons in groups based on their ability to be trained in independent living skills. Cluster analysis was used to group the subjects according to four domains: communication, daily living, socialization, and maladaptive behavior. The results indicate that the behavior scale can be used to classify hearing-impaired persons according to their ability to acquire independent living skills. The cluster analysis resulted in three groups. The persons in the lowest group did not have the most severe hearing losses, but they were more likely to have additional handicaps. This suggests that additional handicaps may be more important than degree of hearing loss in determining whether hearing-impaired persons can acquire independent living skills.

  18. Linking hearing impairment, employment and education.

    2016-12-01

    To analyse the impact that hearing impairment and other relevant variables have on the education and employment situation of those affected by it in the Principality of Asturias, Spain. To achieve this objective, two discrete choice models (probit) are presented. The first one associates, among other variables, hearing impairment with the individual's employment status and in the second model, an ordered multinomial probit model is used to analyse, among other variables, how the impairment affects the individual's level of studies. Although the levels of statistical significance are low, the model's estimates appear to indicate that hearing impairment in Spain increases the probability of being unemployed by 18.4% (P = 0.09). Additionally, the people suffering from such a disability are, compared with the rest of the population, 10.2% (P = 0.05) more likely to have only completed elementary studies without pursuing any further education. If an individual is able to reach a level of secondary or higher education thus enabling a future incorporation to the work place, a benefit is obviously generated for both the individual as well as society (which has additionally incurred an investment in human capital). In this regard, encouraging the education of hearing-impaired students would profit both the individual (who receives an early integration as a child), which may contribute positively to family and social factors, as well as society who have incurred the investment. Therefore, our result could indicate that programmes created to support individuals with this type of disability represent an increase of welfare both individually and socially.

    Little gender-specific data related to hearing loss and hearing loss management are available. The purpose of this investigation was to examine personal and social conditions affecting women at selected stages of the adult life course that may influence hearing loss management. In all, 191 women in three age groups, ranging from 35 to 85 years old, participated. None reported hearing problems. Participants completed a demographic data form and were given a standard audiometric evaluation to confirm age-normal hearing. Each completed assessments of speech understanding in quiet and noise, auditory signal duration discrimination, and binaural processing. Measures of hearing knowledge, behaviors, and attitudes; health-related locus of control; ego strength; and, social support were administered. Results revealed that although some variables deteriorate among subsequent age groups (i.e., hearing thresholds, central auditory processing, and ego strength), the reverse is true for others (i.e., social interaction and satisfaction with income). Age-specific sociodemographic burdens that may interfere with hearing loss management were noted. New psychosocial data are revealed against which women and men with impaired hearing may be compared.

  20. Career planning for hearing impaired employees

    1983-06-01

    In recognition of the special needs of hearing-impaired employees, Union Carbide Nuclear Division staff members restructured and rewrote the existing Career Planning Program to accommodate the barriers experienced by deaf people. Consideration for reworking the training program included awareness that hearing-impaired people: learn mostly through their eyes; use sign language, which is grammatically and structurally different than the English language; have a limited understanding of the English language; live in an isolated world influenced mostly by the deaf community; and have sometimes been stigmatized because of their handicap, resulting in the belief by their parents and others in the hearing world that they lack in intelligence and ability. Twelve deaf employees participated in the program, including four from the Oak Ridge Gaseous Diffusion Plant, six from the Oak Ridge National Laboraory, and two from the Department of Energy. All twelve employees completed the 6 1/2 days of sessions spanning over six weeks, evaluating the program overall as very good. Although most did not feel a need for career change, they learned strategies for enhancing and developing their current positions. They also discovered they were not alone in many feelings of isolation or lack of self-confidence, and that many of their problems are shared by hearing people.

    Students with hearing impairments who are educated in classes with normally hearings peers represent the majority of children with hearing impairment. With hearing losses ranging from mild to profound, they require services to optimize their use of residual hearing and reduce the secondary effects of hearing loss, such as communication deficits and academic delays. For most of these students, the speech-language pathologist will be the on-site specialist in hearing responsible for designing a collaborative rehabilitation/education plan that addresses all deficit areas and for assisting in its implementation in the classroom.

  10. Case studies of pronoun development in two hearing-impaired children: normal, delayed or deviant?

    PubMed

    Cole, E B; Oshima-Takane, Y; Yaremko, R L

    1994-01-01

    This paper is a study of first and second person pronoun development in the spoken language of two young hearing-impaired children. Pronoun development was examined over a period of 11 months, starting at the age of 29 and 28 months, to determine whether the children's acquisition of these pronouns would reflect normal, delayed or deviant patterns of development. Comparison of data from these children with data regarding normally developing children shows the hearing-impaired children's acquisition to be within normal expectations for hearing age and overall linguistic level, and only slightly delayed in terms of chronological age. These results lend support to the view that differences in the hearing-impaired child's language ability are probably the result of a relative lack of auditory and linguistic experience, rather than reorganisation of the hearing-impaired child's psychological and cognitive processing abilities.

  11. Correlates of syntactic abilities in hearing-impaired students.

    PubMed

    Clarke, B R; Rogers, W T

    1981-03-01

    Total scores on the recently developed Screening Test from the Test of Syntactic Abilities for 382 hearing-impaired subjects between eight and 19 years and in various educational programs were found to be significantly related to hearing threshold level, number of multiple handicaps, age, educational setting, method of communication, and hearing aid usage. Multivariate analysis of variance on the effect of age controlled for hearing loss showed no significant increase in scores after eleven years of age, thus lending support to the thesis that the capacity to acquire language may cease to function at about puberty. The results of stepwise multiple regression analyses showed that, when personal variables were first forced to enter the equation, degree of hearing loss, multiple handicaps, and age accounted for 14%, nine %, an four % of the explained variability, respectively. Over and above these contributions, two manipulable variables--educational setting (a surrogate for integration) and method of communication--added significantly a further 12% and three % to the explained variability in syntactic ability.

    The School for Young Deaf Children was founded in 1969 when the All India Institute of Speech and Hearing at Mysore and the Christian Medical College Hospital at Vellore started diagnosing hearing impairment in children and prescribing hearing aids. These schools admitted children when they were 5 years old. Bala Vidyalaya was funded as an experimental school to satisfy the needs of younger children. A multi sensory approach based on the Montessori method of teaching with special emphasis on language acquisition was adopted. The School that began with 5 children and 2 teachers had 120 children and 15 teachers in 1992: 50 children were under 3 years old and the rest were between 3 and 6 years. Early auditory management and training is the foundation of the child's linguistic achievement which help the child use the innate ability to develop sophisticated listening skills such as listening to one signal in the presence of competing sounds. Simple games captivate the infants. At the age of 2 1/2 years ideovisual reading is introduced to the child: written sentences are presented to the child about an activity that the child had just experienced. Even before 2 years of age he or she starts scribbling. School lessons are used as tools for writing. The school takes efforts to win the confidence of the parents. So far 97 children have joined the mainstream of education after an initial training the school. Of these, 6 are settled in jobs, 5 are in college or in postgraduate studies, 11 are studying at the university, 8 are in the higher secondary school (classes XI or XII)m 28 are studying in high school (class VI to class X), while the remaining 39 are in primary schools. It has been demonstrated that early educational intervention and involvement of the family into the educational program are very important for the successful integration of hearing-impaired children into the main stream.

    Background and aims Deleterious oral habits represent a serious public health issue. The information available about this problem in children with hearing impairment is insufficient. The purpose of this study was to investigate the prevalence of deleterious oral habits among children with hearing impairment and comparing results against children without hearing impairment. Method This epidemiological study was carried out in a sample size of 315 children. We used a random sampling technique that included 150 children with hearing impairment and 165 without hearing impairment. All subjects were submitted to a clinical examination. The parents/legal guardians were asked to complete a questionnaire regarding the deleterious habits of their children. Results The data collected indicated a higher prevalence of deleterious oral habits among children with hearing impairment: 53.3% as opposed to 40.6% among children without hearing impairment. There was a higher incidence of malocclusion in children with hearing impairment (79.3%) compared to children without hearing impairment (57%). Conclusions This study highlighted the need to establish protocols for preventive orthodontic treatment at an early age, in order to reduce the deleterious oral habits and prevent malocclusion. Dental institutions/clinicians need to implement oral care programs including proper oral education aiming to promote oral health. PMID:26609277

    Elderly persons with a physiologic hearing deficit (hearing impairment) are not necessarily socially or emotionally disturbed by the deficit in everyday life (hearing handicap). The self-perception of a hearing handicap in elderly people is a key element in seeking consultation for a hearing impairment or using hearing aids. Thus, it is important to determine the factors associated with the self-perception of a hearing handicap. The aims of the present study were to report the relation between a hearing impairment and the self-perception of a hearing handicap, and the factors associated with a self-perceived hearing handicap among a group of randomly recruited, community-dwelling elderly persons, aged 65 yr and older, in Taipei, Taiwan. A cross-sectional survey of community-dwelling elderly persons aged 65 yr and older (N = 1220) participating in an annual general purpose geriatric health examination in 2005 in Taipei. Pure-tone audiometry and a questionnaire including the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S) were administered, after obtaining the subject's consent to participate in the study. Demographic information, lifestyle, self-report health status, and biochemical data were also collected. There was a moderate association (gamma(s) = 0.52) between hearing impairment and self-perceived handicap. Only 21.4% of the study subjects with moderate to profound hearing impairment (M4 >or=41 dB HL, N = 555) perceived themselves as hearing-handicapped (HHIE-S total score >or=10). Besides hearing level, marital status (widowed) and self-perceived general health (bad or neutral) were factors that are significantly associated with a self-perceived hearing handicap among elderly subjects with moderate to profound hearing impairment. For study subjects with moderate to profound hearing impairment (M4 >or=41 dB HL), 5.0% of those with HHIE-S <10 and 45.4% of those with HHIE-S >or=10 used or felt that they required hearing aids (chi2 test, p

  17. Timbre discrimination in normal-hearing and hearing-impaired listeners under different noise conditions.

    2008-07-18

    In an attempt to quantify differences in object separation and timbre discrimination between normal-hearing and hearing-impaired listeners with a moderate sensorineural hearing loss of two different configurations, psychoacoustic measurements were performed with a total of 50 listeners. The experiments determined just noticeable differences (JND) of timbre in normal-hearing and hearing-impaired subjects along continua of "morphed" musical instruments and investigated the variance of JND in silence and different background noise conditions and on different sound levels. The results show that timbre JNDs of subjects with a steep hearing loss are significantly higher than of normal-hearing subjects, both in silence and noise, whereas timbre JNDs of flat/diagonal hearing-impaired subjects are similar to JNDs of normal-hearing subjects for signal levels above 55 dB (plus appropriate amplification for hearing-impaired). In noise (SNR=+10 dB) timbre JNDs of all subject groups are significantly higher than in silence. In the condition testing, transferability from silence to noise (i.e., the ability to imagine how the stimulus heard in silence would sound in noise), no significant JND differences across listener groups were found. The results can be explained by primary factors involved in sensorineural hearing loss and contradict the hypothesis that hearing-impaired people generally have more problems in object discrimination than normal-hearing people.

    1992-02-01

    The performance on a conversation-following task by 24 hearing-impaired persons was compared with that of 24 matched controls with normal hearing in the presence of three background noises: (a) speech-spectrum random noise, (b) a male voice, and (c) the male voice played in reverse. The subjects' task was to readjust the sound level of a female voice (signal), every time the signal voice was attenuated, to the subjective level at which it was just possible to understand what was being said. To assess the benefit of lipreading, half of the material was presented audiovisually and half auditorily only. It was predicted that background speech would have a greater masking effect than reversed speech, which would in turn have a lesser masking effect than random noise. It was predicted that hearing-impaired subjects would perform more poorly than the normal-hearing controls in a background of speech. The influence of lipreading was expected to be constant across groups and conditions. The results showed that the hearing-impaired subjects were equally affected by the three background noises and that normal-hearing persons were less affected by the background speech than by noise. The performance of the normal-hearing persons was superior to that of the hearing-impaired subjects. The prediction about lipreading was confirmed. The results were explained in terms of the reduced temporal resolution by the hearing-impaired subjects.

  1. Motor Skills in Hearing Impaired Children with or without Cochlear Implant--A Systematic Review.

    2015-07-01

    Hearing impairment is a major limitation in communication, and it can obstruct psychological development, development of social skills and motor development. Hearing impairment is the third most common contemporary chronic health condition, and it has become a public health problem. The effectiveness of problem solving in everyday life and in emergency situations depends greatly on the amount and quality of the motor programs. Therefore, it is evident that the normal motor development in persons with hearing impairment is essential for everyday life. The aim of this research is to analyze the available information pertaining to motor skills of hearing impaired children both with and without a cochlear implant (CI) and to analyze possibilities of influencing their motor skills. The relevant studies on motor skills of hearing impaired children both with and without CI were obtained by an extensive computer search of various databases using special keywords and extraction with respect to certain criteria, resulting in 22 studies. The overall results of this systematic review indicate that the children with hearing impairment exhibit suboptimal levels of motor skills especially balance. Very few studies compared children with hearing impairment with CI units and without CI units and the results of those studies are quite contradictory. Numerous studies have confirmed that the regular and appropriate physical exercise can improve motor skills of children with hearing impairment, especially balance. The fact that the development of motor skills is crucial for the child's interaction with the outside world, action, perception and acquisition of academic skills and other skills necessary for life shows the importance of motor skills development for children with hearing impairment.

    This study analyzes the differences in manual reaction time (RT) to visual stimuli in two samples of physically active persons: a group of athletes without hearing impairment (n = 79; M age = 22.6 yr., SD = 3.7) and a group of athletes with hearing impairment (n = 44, M age = 25.6 yr., SD = 5.0). Reaction time (RT) was measured and then differences between both groups were assessed by sex, type of sport (individual vs team sports), and competition level. RT to visual stimuli was significantly shorter for athletes with hearing impairment than for those without hearing impairment, with a significant sex difference (shorter RT for males), but no differences regarding type of sport or competition level. Suggestions for further research and sport applications are provided.

  3. Problems of hearing impaired children and suggested solutions.

    1992-01-01

    Factors related to development of verbal skills in hearing-impaired children include early diagnosis, early age of obtaining hearing aids, and early intervention. The development of speech occurs in the first 2 years of one's life. In addition to the hearing aid the child should also get early stimulation and training by parents and professionals toward developing speech and language. The hearing-impaired child is likely to get the benefit of a hearing aid only if it amplifies sound in accordance with his or her hearing loss. Proper audiological examination assesses the level of hearing loss and helps select a suitable hearing aid by conducting an aided audiogram. Parents who accept their child's problem are in a better emotional state to assist their child. The relationship between the degree of hearing impairment and development of verbal skills is analyzed by performance on the verbal section of the Weschler Intelligence Scale for Children (WISC). Analysis of WISC results showed that in a group of 24 children with severe to profound hearing loss only 12% were able to answer questions on the verbal section of WISC. These children were attending normal schools and had developed almost normal speech and language with high parental involvement. In a group of 16 children with moderate and conductive hearing loss 80% were able to deal with the verbal section. Hearing-impaired children who attend school have better prospects of receiving structured stimulation for language development. There are only 2 special schools available for 3-5 year old children in Delhi. Services could be improved by spelling out in the educational policy of training programs for teachers of hearing-impaired children that 1) the method of teaching must be decided on the basis of the hearing-impaired child's capabilities and 2) teachers must conduct proper auditory stimulation programs.

    Szterman, Ronit; Friedmann, Naama

    2014-01-01

    Children with hearing impairment show difficulties in sentences derived by Wh-movement, such as relative clauses and Wh-questions. This study examines the nature of this deficit in 48 hearing impaired children aged 9-12 years and 38 hearing controls. The task involved reading aloud and paraphrasing of object relatives that include a noun-verb heterophonic homograph. The correct pronunciation of the homograph in these sentences depended upon the correct construction of the syntactic structure of the sentence. An analysis of the reading and paraphrasing of each participant exposed two different patterns of syntactic impairment. Some hearing-impaired children paraphrased the object relatives incorrectly but could still read the homograph, indicating impaired assignment of thematic roles alongside good syntactic structure building; other hearing-impaired children could neither read the homograph nor paraphrase the sentence, indicating a structural deficit in the syntactic tree. Further testing of these children confirmed the different impairments: some are impaired only in Wh-movement, whereas others have CP impairment. The syntactic impairment correlated with whether or not a hearing device was fitted by the age of 1 year, but not with the type of hearing device or the depth of hearing loss: children who had a hearing device fitted during the first year of life had better syntactic abilities than children whose hearing devices were fitted later.

    This study compares the occupational performance of employees with and without hearing impairment, and aims to identify occupational difficulties specifically related to hearing loss. The Amsterdam Checklist for Hearing and Work was administered to 150 hearing-impaired employees and 60 normally-hearing colleagues. A multivariate analysis of variance was performed to test group effects, and to examine differences between means. Factors predicting sick-leave were identified by regression analyses. A significant group effect (p < 0.01) was found. Hearing-impaired employees differed from normally-hearing colleagues in their perception of 'environmental noise', 'job control' and the 'necessity to use hearing activities' at work. Also, sick-leave due to distress occurred significantly more often in the hearing impaired group (p < 0.05). 'Hearing impairment', 'job demand', and the requirement to 'recognize/distinguish between sounds' were the strongest risk-factors for stress related sick-leave. The importance of hearing functions besides speech communication is discussed. Implications for rehabilitation are suggested. In future research, hearing loss should be considered as a risk factor for fatigue and mental distress which may lead to sick-leave.

    To develop a version of the Montreal Cognitive Assessment (MoCA) to be administered to the severely hearing impaired (HI-MoCA), and to assess its performance in two groups of cognitively intact adults over the age of 60. Test development followed by prospective subject recruitment. The MoCA was converted into a timed PowerPoint (Microsoft Corp., Redmond, WA) presentation, and verbal instructions were converted into visual instructions. Two groups of subjects over the age of 60 were recruited. All subjects passed screening questionnaires to eliminate those with undiagnosed mild cognitive impairment. The first group had normal hearing (group 1). The second group was severely hearing impaired (group 2). Group 1 received either the MoCA or HI-MoCA test (T1). Six months later (T2), subjects were administered the test (MoCA or HI-MoCA) they had not received previously to determine equivalency. Group 2 received the HI-MoCA at T1 and again at T2 to determine test-retest reliability. One hundred and three subjects were recruited into group 1, with a score of 26.66 (HI-MoCA) versus 27.14 (MoCA). This was significant (P < 0.05), but scoring uses whole numerals and the 0.48 difference was found not clinically significant using post hoc sensitivity analyses. Forty-nine subjects were recruited into group 2. They scored 26.18 and 26.49 (HI-MoCA at T1 and T2). No significance was noted (P > 0.05), with a test-retest coefficient of 0.66. The HI-MoCA is easy to administer and reliable for screening cognitive impairment in the severely hearing impaired. No conversion factor is required in our prospectively tested cohort of cognitively intact subjects. 1b.

    A multichannel electronic visual aid device which is able to signal to the user whether sound is coming from the left or right, front or back, or both is presented. For the plurality of channels, which may operate in pairs, the sound is picked up by a respective microphone and amplified and rectified into a DC voltage. The DC voltage is next fed to an analog to digital converter and then to a digital encoder. The binary code from the encoder is coupled into a logic circuit where the binary code is decoded to proved a plurality of output levels which are used to drive an indicator which, in turn, provides a visual indication of the sound level received. The binary codes for each pair of channels are also fed into a digital comparator. The output of the comparator is used to enable the logic circuits of the two channels such that if, for example, the signal coming from the right is louder than that coming from the left, the output of the logic unit of the right channel will be enabled and the corresponding indicator activated, indicating the sound source on the right. An indication of the loudness is also provided. One embodiment of the invention may be carried by the hearing impaired or deaf, as a system which is embedded into eye glasses or a cap. Another embodiment of the invention may be integrated with a vehicle to give a hearing impaired or deaf driver a warning, with a directional indication, that an emergency vehicle is in the vicinity. In this second embodiment, the emergency vehicle transmits a radio frequency signal which would be used as an enabling signal for the visual aid device to avoid false alarms from traffic and other sound sources in the vicinity of the driver's vehicle.

  3. Inflectional morphology in German hearing-impaired children.

    PubMed

    Penke, Martina; Wimmer, Eva; Hennies, Johannes; Hess, Markus; Rothweiler, Monika

    2016-01-01

    Despite modern hearing aids, children with hearing impairment often have only restricted access to spoken language input during the 'critical' years for language acquisition. Specifically, a sensorineural hearing impairment affects the perception of voiceless coronal consonants which realize verbal affixes in German. The aim of this study is to explore if German hearing-impaired children have problems in producing and/or acquiring inflectional suffixes expressed by such phonemes. The findings of two experiments (an elicitation task and a picture-naming task) conducted with a group of hearing-impaired monolingual German children (age 3-4 years) demonstrate that difficulties in perceiving specific phonemes relate to the avoidance of these same sounds in speech production independent of the grammatical function these phonemes have.

    1988-09-01

    The purpose of this study was to compare the summary writing skills of hearing-impaired and normally hearing college students. Summarization was defined in terms of the following measures: deletion of trivial text information, inclusion of most important ideas, selection of topic sentences, creation of topic statements, and integration of information within and among several paragraphs. Inclusion of opinionated, incorrect, and uninterpretable information was measured also. Thirty hearing-impaired and 30 normally hearing students read and summarized two expository science passages that were controlled for the number of topic (main idea) sentences and that had been rated previously for the importance of "idea units." Students' factual comprehension also was assessed. Hearing-impaired and normally hearing students exhibited a similar pattern of use among several measured summarization strategies, except for the inclusion of opinions or comments in their summaries. Hearing-impaired students were not as sensitive as normally hearing students to importance of ideas and used the following summarization strategies significantly less often: inclusion of important ideas, selection of topic sentences, creation of topic statements, and integration of ideas within and among paragraphs. The results indicated that hearing-impaired college students have basic summarization skills but do not apply summarization strategies as effectively as normally hearing students.

    A human being takes in the outer world information by using the five senses, and lives. So he is forced very inconvenient life even when one sense is missing. Among others, it is said that the sense of hearing has importance next to the sight, but it is one of the organs which surely become weak with aging, and "hearing defect" is particularly the problem which all people face someday. But, technically and socially, the system which the person whose physical function is poor can entry into and contribute to the society is very important. In this research, the way of making up for a lost function by the medium change to the sense of touch information from the auditory information is examined, as a help that hearing-impaired gets "safety", "independence", "the tranquility of the heart" from the technical side. In this paper, as a concrete system, it paid attention to the mouse of the PC interface, and a vibration mouse was used under the environment which a PC was being used for, and thought about building of the system which can acquire the sound information of the life environment in real time.

    The objective of this study was to evaluate hearing aid fitting from a societal viewpoint, rather than the more traditional patient perspective. The effects of hearing aid fitting on generic quality of life (EuroQol), social functioning (SF36), auditory disability, productivity at paid and unpaid labour, and medical consumption, were assessed in a prospective study among 80 moderately hearing-impaired first-time hearing aid applicants. The study showed that hearing aid fitting solved problems with paid employment, but did not seem to affect unpaid work. Use of medical services remained relatively stable after first-time hearing aid fitting. The Amsterdam Inventory proved to be a useful questionnaire to assess the effects on hearing disability. No effects of hearing aid fitting on generic quality of life could be determined with the EuroQol, while hearing aid fitting did lead to an improvement in one aspect of generic quality of life; namely social functioning.

    Since the pragmatic skills of hearing-impaired Persian-speaking children have not yet been investigated particularly through story retelling, this study aimed to evaluate some pragmatic abilities of normal-hearing and hearing-impaired children using a story retelling test. 15 normal-hearing and 15 profound hearing-impaired 7-year-old children were evaluated using the story retelling test with the content validity of 89%, construct validity of 85%, and reliability of 83%. Three macro structure criteria including topic maintenance, event sequencing, explicitness, and four macro structure criteria including referencing, conjunctive cohesion, syntax complexity, and utterance length were assessed. The test was performed with live voice in a quiet room where children were then asked to retell the story. The tasks of the children were recorded on a tape, transcribed, scored and analyzed. In the macro structure criteria, utterances of hearing-impaired students were less consistent, enough information was not given to listeners to have a full understanding of the subject, and the story events were less frequently expressed in a rational order than those of normal-hearing group (P < 0.0001). Regarding the macro structure criteria of the test, unlike the normal-hearing students who obtained high scores, hearing-impaired students failed to gain any scores on the items of this section. These results suggest that Hearing-impaired children were not able to use language as effectively as their hearing peers, and they utilized quite different pragmatic functions.

    Worker's compensation for hearing loss caused by occupational noise exposure is calculated by varying methods, from state to state within the United States (US), with many employing arithmetic formulas based on the pure-tone audiogram, to quantify hearing loss. Several assumptions unsupported or weakly supported by empirical data underlie these formulas. The present study evaluated the ability of various arithmetic hearing impairment calculations to predict a self-reported hearing handicap in a sample of presenting with sensorineural hearing loss. 204 adults (127 male, 77 female) ranging in age from 18 to 94 served as participants. The sample was selected to exclude patients who had been referred for hearing testing for a medicolegal examination or a hearing conservation appointment. A hearing handicap was measured by the Hearing Handicap Inventory for Adults/for the Elderly (HHIA/E). The covariance analysis of linear structural equations was used to assess the relative strength of correlation with the HHIA/E score among the six formulas and various forms of pure-tone average. The results revealed that all the hearing impairment calculations examined were significantly, but weakly, correlated with the self-reported hearing impairment scores. No significant differences among the predictive abilities of the impairment calculations were evident; however, the average binaural impairment assigned differed significantly among the six calculations examined. Individuals who demonstrated 0% impairment had significantly lower (i.e., better) HHIA/E scores compared to those with non-zero impairment for each formula. These results supported the idea that audiometric data provided an insufficient explanation for real-world hearing difficulties.

    The aim of this study was to compare the visual field (VF) categorizations (based on the severity of VF defects) between adolescent boys with hearing impairments and those with normal hearing. This cross-sectional study involved the evaluation of the VF of 64 adolescent boys with hearing impairments and 68 age-matched boys with normal hearing at high schools in Tehran, Iran, in 2013. All subjects had an intelligence quotient (IQ) > 70. The hearing impairments were classified based on severity and time of onset. Participants underwent a complete eye examination, and the VFs were investigated using automated perimetry with a Humphrey Visual Field Analyzer. This device was used to determine their foveal threshold (FT), mean deviation (MD), and Glaucoma Hemifield Test (GHT) results. Most (50%) of the boys with hearing impairments had profound hearing impairments. There was no significant between-group difference in age (P = 0.49) or IQ (P = 0.13). There was no between-group difference in the corrected distance visual acuity (P = 0.183). According to the FT, MD, and GHT results, the percentage of boys with abnormal VFs in the hearing impairment group was significantly greater than that in the normal hearing group: 40.6% vs. 22.1%, 59.4% vs. 19.1%, and 31.2% vs. 8.8%, respectively (P < 0.0001). The mean MD in the hearing impairment group was significantly worse than that in the normal hearing group (-0.79 ± 2.04 and -4.61 ± 6.52 dB, respectively, P < 0.0001), and the mean FT was also significantly worse (38.97 ± 1.66 vs. 35.30 ± 1.43 dB, respectively, P <0.0001). Moreover, there was a significant between-group difference in the GHT results (P < 0.0001). Thus, there were higher percentages of boys with VF abnormalities and higher mean MD, FT, and GHT results among those with hearing impairments compared to those with normal hearing. These findings emphasize the need for detailed VF assessments for patients with hearing impairments. PMID:28293650

    Hearing impairment (HI) remains a problem among dentists Hearing loss at speech frequencies was recently reported among dentists and dental hygienists. This study aimed to investigate prevalence and factors associated with perceived HI among dentists. In 2009-2010, 100 general dental practitioners (GDPs) and 115 general (medical) practitioners (GPs) (mean ages, 43.7 and 44.4 years) from Rome (Italy), who commenced practice ≥ 10 years ago, were interviewed on a series of occupation- and recreation-related HI risk factors and on HI-associated symptoms (tinnitus, sensation of fullness, hypoacusis). Prevalence of presumptive HI (≥ 1 symptom perceived during workdays and weekends) was assessed and factors associated with presumptive HI were investigated. Prevalence was 30.0% (95% confidence interval, 21.0-39.0%) and 14.8% (95% confidence interval, 8.3-21.3%) among GDPs and GPs, respectively. Occupation (GDP vs. GP), family history of hypoacusis, hypertension, ear diseases and smoking were significantly associated with presumptive HI. Within GDPs alone, significant associations were found for frequent use of ultrasonic scalers, use of dental turbines aged≥1 year and prosthodontics as prevalent specialty. GDPs experienced HI risk than GPs. Such a risk was not generalized to all dentists, but was specific for those who frequently used noisy equipment (aged turbines, ultrasonic scalers) during their daily practice. GDPs with 10 or more years of practice who routinely use potentially noisy equipment, could be at risk of HI. In order to prevent such condition, daily maintenance and periodical replacement of dental instruments is recommended. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Objectives The aim of the study was to determine the characteristics of patients who did not match the audiometric criteria of idiopathic sudden sensorineural hearing loss (SSNHL) but complained of acute hearing loss. Methods By thorough medical chart reviews, historical cohort study was performed with consecutive data of 589 patients complaining of acute unilateral sensorineural hearing loss without identifiable causes between 2005 and 2013. Those patients demonstrating a hearing loss of at least 30 dB at three consecutive frequencies based on pure tone audiometry were classified as group I; the others were classified as group II. Patients' characteristics, final hearing, and hearing improvement rate (HIR) between the two groups were compared. Results Group II exhibited distinctive characteristics, including an early age of onset of the hearing loss (P<0.01), an absence of accompanying diabetes (P<0.01) and hypertension (P<0.01), and better unaffected hearing and final hearing compared with group I (P<0.001). However, the HIR of the patients in the two groups was not significantly different (P>0.05). Conclusion Patients who did not meet the audiological criteria of SSNHL exhibited distinctive characteristics compared to SSNHL patients. PMID:26622953

    Objectives: Children with hearing loss are at risk of developing psychopathology, which has detrimental consequences for academic and psychosocial functioning later in life. Yet, the causes of the extensive variability in outcomes are not fully understood. Therefore, the authors wanted to objectify symptoms of psychopathology in children with cochlear implants or hearing aids, and in normally hearing peers, and to identify various risk and protective factors. Design: The large sample (mean age = 11.8 years) included three subgroups with comparable age, gender, socioeconomic status, and nonverbal intelligence: 57 with cochlear implants, 75 with conventional hearing aids, and 129 children who were normally hearing. Psychopathology was assessed by means of self- and parent-report measures. Results: Children with cochlear implants showed similar levels of symptoms of psychopathology when compared with their normally hearing peers, but children with hearing aids had significantly higher levels of psychopathological symptoms, while their hearing losses were approximately 43 dB lower than those of children with implants. Type of device was related with internalizing symptoms but not with externalizing symptoms. Furthermore, lower age and sufficient language and communication skills predicted less psychopathological symptoms. Conclusions: Children who are deaf or profoundly hearing impaired and have cochlear implants have lower levels of psychopathological symptoms than children with moderate or severe hearing loss who have hearing aids. Most likely, it is not the type of hearing device but rather the intensity of the rehabilitation program that can account for this difference. This outcome has major consequences for the next generation of children with hearing loss because children with profound hearing impairment still have the potential to have levels of psychopathology that are comparable to children who are normally hearing.

    Present descriptive study was carried out for the assessment of hearing capability in leprosy patients. After getting approval from Institutional ethical committee, the present descriptive study was carried out on 60 subjects. All the patients were indoor-patients at the Leprosy Rehabilitation Center Maharogi Sewa Samiti Anandvan Warora, and were on multidrug therapy described by World Health Organization from an average period of 6 months. Study Group I consisted of 30 diagnosed Leprosy patients taking multidrug therapy from an average period of 6 months. Group II (Control group) consisted of 30 normal healthy individuals of same age. Patients suffering from acute or chronic ear discharge, Presence of wax in external auditory canal, diabetes mellitus, hypertension, impaired renal function and patients having history of trauma were excluded from the study. All the subjects underwent Pure tone audiometry, Tuning Fork test to check the level of hearing loss and type of hearing loss and detailed clinical examination for cranial nerve function was done in all the patients of study group and control group. Audiometry findings in study group patients showed that 23 patients (76.66%; 45 ears) of the leprosy patients had sensory neural hearing impairment and 7 patients (23.33%) showed normal hearing. Out of these affected patients, 10 patients (43.47%; 19 ears) had mild sensory neural hearing impairment, 10 patients (43.47%; 20 ears) had moderate sensory neural hearing impairment. 2 patients (8.69%; 04 ears) had moderate to severe hearing impairment, 1 patient (4.34%; 02 ears) showed severe sensory neural hearing impairment. In the absence of any local or systemic disease or drugs likely to have side effects on the cochleovestibular function, leprosy affects the cochleovestibular system, and effect on cochlear function is seen more often than effect on the vestibular system. Thus hearing loss which is seen in patients suffering from Hansen's disease is of cochlear origin.

  16. Auditory handicap of hearing impairment and the limited benefit of hearing aids.

    PubMed

    Plomp, R

    1978-02-01

    The aim of this article is to promote a better understanding of hearing impairment as a communicative handicap, primarily in noisy environments, and to explain by means of a quantitative model the essentially limited applicability of hearing aids. After data on the prevalence of hearing impairment and of auditory handicap have been reviewed, it is explained that every hearing loss for speech can be interpreted as the sum of a loss class A (attenuation), characterized by a reduction of the levels of both speech signal and noise, and a loss D (distortion), comparable with a decrease in speech-to-noise ratio. On the average, the hearing loss of class D (hearing loss in noise) appears to be about one-third (in decibels) of the total hearing loss (A + D, hearing loss in quiet). A hearing aid can compensate for class-A-hearing losses, giving difficulties primarily in quiet, but not for class-D hearing losses, giving difficulties primarily in noise. The latter class represents the first stage of auditory handicap, beginning at an average hearing loss of about 24 dB.

  12. Hearing impairment in Stickler syndrome: a systematic review

    PubMed Central

    2012-01-01

    Background Stickler syndrome is a connective tissue disorder characterized by ocular, skeletal, orofacial and auditory defects. It is caused by mutations in different collagen genes, namely COL2A1, COL11A1 and COL11A2 (autosomal dominant inheritance), and COL9A1 and COL9A2 (autosomal recessive inheritance). The auditory phenotype in Stickler syndrome is inconsistently reported. Therefore we performed a systematic review of the literature to give an up-to-date overview of hearing loss in Stickler syndrome, and correlated it with the genotype. Methods English-language literature was reviewed through searches of PubMed and Web of Science, in order to find relevant articles describing auditory features in Stickler patients, along with genotype. Prevalences of hearing loss are calculated and correlated with the different affected genes and type of mutation. Results 313 patients (102 families) individually described in 46 articles were included. Hearing loss was found in 62.9%, mostly mild to moderate when reported. Hearing impairment was predominantly sensorineural (67.8%). Conductive (14.1%) and mixed (18.1%) hearing loss was primarily found in young patients or patients with a palatal defect. Overall, mutations in COL11A1 (82.5%) and COL11A2 (94.1%) seem to be more frequently associated with hearing impairment than mutations in COL2A1 (52.2%). Conclusions Hearing impairment in patients with Stickler syndrome is common. Sensorineural hearing loss predominates, but also conductive hearing loss, especially in children and patients with a palatal defect, may occur. The distinct disease-causing collagen genes are associated with a different prevalence of hearing impairment, but still large phenotypic variation exists. Regular auditory follow-up is strongly advised, particularly because many Stickler patients are visually impaired. PMID:23110709

    of this association remains unclear. Many of the authors conclude that hearing impairment is unlikely to be an etiological factor in autism. However, auditory impairment may be a marker for brain damage in autism. Although some studies showed high rates of depression and anxiety disorders, particularly social phobias, in deaf and hard-of-hearing children and adolescents, most of the studies conclude that the prevalence of affective disorders in hearing-impaired children and adolescents is comparable with estimates of prevalence for hearing young people. A number of studies have suggested that deaf children show greater degrees of impulsivity than hearing children. However, it seems that this background of greater impulsivity does not lead to higher rates of attention-deficit/hyperactivity disorder (ADHD) among deaf children. Using standardized instruments to estimate the prevalence of ADHD in this population, recent studies conclude that deaf children with hereditary deafness are not at greater risk of developing ADHD but that children with acquired deafness are, and that this difference is probably related to the medical conditions and family climates distinguishing these two groups. Psychotic disorders are no more common among hearing-impaired young people than among young people with normal hearing. However, some recent studies showed that the presentation of schizophrenia can differ in deaf people because of the high frequency of visual hallucinations observed in them. Lastly, if primitive personality has been described as being more prevalent among hearing-impaired children and adolescents, most of the studies found a normal range of emotional-behavioral functioning in them. In summary, if varying incidences of emotional disturbances and behavioral problems have been reported for hearing-impaired children and adolescents, except autism, it seems that children with hearing impairment experience the same range of mental health problems as hearing children.

    2011-01-01

    A self-fitting hearing aid is a personal amplification device that is designed to be assembled, programmed, and fine-tuned by the user, without the need for additional equipment or professional support. A written description of the device was presented to 80 older adults with a hearing impairment, all of whom were residents of an urban area in a developed country. In response to a structured questionnaire, the majority of participants reported that the self-fitting hearing aid concept was a good idea (83%), would be of personal benefit (60%), and could be managed independently by the user (90%). Overall, half of the participant group agreed with all three statements. Two were uncertain about the concept, but none of the participants rejected it outright. There were no significant differences between the opinions of participants with previous hearing aid experience and those without. Participant responses to open-ended questions revealed that the main benefits of a self-fitting hearing aid were thought to be the ability to self-adjust the device’s settings (reported by 33% of participants) and increased convenience (20% of participants). The main drawback, mentioned by 25% of participants, was a preference for professional guidance through the fitting process. These results suggest that the self-fitting hearing aid may present as an alternative product in developed countries for those users who prefer to be in control of the fitting process. PMID:22079900

    To systematically assess the data on the prevalence and causes of hearing impairment in Africa. Systematic review on the prevalence and causes of hearing loss in Africa. We undertook a literature search of seven electronic databases (EMBASE, PubMed, Medline, Global Health, Web of Knowledge, Academic Search Complete and Africa Wide Information) and manually searched bibliographies of included articles. The search was restricted to population-based studies on hearing impairment in Africa. Data were extracted using a standard protocol. We identified 232 articles and included 28 articles in the final analysis. The most common cut-offs used for hearing impairment were 25 and 30 dB HL, but this ranged between 15 and 40 dB HL. For a cut-off of 25 dB, the median was 7.7% for the children- or school-based studies and 17% for population-based studies. For a cut-off of 30 dB HL, the median was 6.6% for the children or school-based studies and 31% for population-based studies. In schools for the deaf, the most common cause of hearing impairment was cryptogenic deafness (50%) followed by infectious causes (43%). In mainstream schools and general population, the most common cause of hearing impairment was middle ear disease (36%), followed by undetermined causes (35%) and cerumen impaction (24%). There are very few population-based studies available to estimate the prevalence of hearing impairment in Africa. Those studies that are available use different cut-offs, making comparison difficult. However, the evidence suggests that the prevalence of hearing impairment is high and that much of it is avoidable or treatable. © 2015 John Wiley & Sons Ltd.

    To evaluate the association of hearing impairment, vision impairment and their combination (dual sensory impairment) with negative well-being such as depression, subjective poor health and the reduced functional ability in community-dwelling older adults, and to determine whether any association varies by gender. Between 2005 and 2006, we objectively examined vision and hearing impairment (using best-corrected visual acuity and pure-tone audiometric test) in 843 people aged 65 years and older (351 males, 492 females) in a rural Japanese town. Through a home visit interview survey using a structured questionnaire, we also collected information on depression (the five-item Geriatric Depression Scale), subjective poor health, and reduced functional activity (the Tokyo Metropolitan Institute of Gerontology's Index of Competence). We observed gender differences in the association between sensory impairment and depression. Multiple logistic regression analysis revealed that hearing impairment in males (adjusted odds ratio: 2.22, 95% confidence interval; 1.07-4.61) and vision impairment in females (1.91, 1.14-3.21) were related to depression. Vision impairment and dual sensory impairment were also associated with subjective poor health and reduced functional activity in both sexes. Sensory impairment is significantly associated with negative well-being in older persons, and its association with depression may differ between males and females.

    To use a computer model of impaired hearing to explore the effects of a physiologically-inspired hearing-aid algorithm on a range of psychoacoustic measures. A computer model of a hypothetical impaired listener's hearing was constructed by adjusting parameters of a computer model of normal hearing. Absolute thresholds, estimates of compression, and frequency selectivity (summarized to a hearing profile) were assessed using this model with and without pre-processing the stimuli by a hearing-aid algorithm. The influence of different settings of the algorithm on the impaired profile was investigated. To validate the model predictions, the effect of the algorithm on hearing profiles of human impaired listeners was measured. A computer model simulating impaired hearing (total absence of basilar membrane compression) was used, and three hearing-impaired listeners participated. The hearing profiles of the model and the listeners showed substantial changes when the test stimuli were pre-processed by the hearing-aid algorithm. These changes consisted of lower absolute thresholds, steeper temporal masking curves, and sharper psychophysical tuning curves. The hearing-aid algorithm affected the impaired hearing profile of the model to approximate a normal hearing profile. Qualitatively similar results were found with the impaired listeners' hearing profiles.

    The implementation of regional protocols for newborn hearing screening and early audiologic diagnosis represent the first step of the entire diagnostic, rehabilitative and prosthetic programme for children with permanent hearing impairment. The maximum benefit of early diagnosis can indeed be obtained only by prompt rehabilitation aimed at fostering the child's communicative, linguistic and cognitive development. Within the framework of the CMM 2013 project of the Ministry of Health entitled "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", the problems concerning the promotion of the global development of children with PHI through an early rehabilitation project based on shared knowledge and scientific evidence. In this project, our specific aim was to define the features and modes of access to a precise and specialised rehabilitation project for the small hearing-impaired child within three months from audiologic diagnosis. Three main recommendations relative to assessment and rehabilitation aspects of early care emerged from the study.

    Aims: The functional state of the auditory analyzer of several operators groups was study. The objective of this study was to determine some characteristics of hearing impairment in relation with features of acoustic stimuli and informative significance of noise. Materials and Methods: 236 employees (middle age 35.4 ± 0.74 years) were divided into four groups according to features of noise perception at the workplaces. The levels of permanent shifts of acoustic thresholds were estimated using audiometric method. Statistical Analysis Used: Common statistical methods were used in research. Mean quantity and mean absolute errors were calculated. Statistical significance between operators' groups was calculated with 0.05 confidential intervals. Results: The peculiarities of hearing impairment in observed groups were different. Operators differentiating acoustic signals had peak of hearing impairment in the field of language frequencies, while the employees who work with noise background at the workplaces had maximal hearing threshold on the 4000 Hz frequency (P ≤ 0.05). Conclusions: Hearing impairment depends both on energy and human interaction with acoustic irritant. The distinctions in hearing impairment may be related with the necessity of recognizing of acoustic signals and their frequency characteristics. PMID:26957812

    This study investigated the acoustic characteristics of the Belgian Standard Dutch vowels in children with hearing impairment and in children with normal hearing. In a balanced experimental design, the 12 vowels of Belgian Standard Dutch were recorded in three groups of children: a group of children with normal hearing, a group with a conventional hearing aid and a group with a cochlear implant. The formants, the surface area of the vowel space and the acoustic differentiation between the vowels were determined. The analyses revealed that many of the vowels in hearing-impaired children showed a reduction of the formant values. This reduction was particularly significant with respect to F2. The size of the vowel space was significantly smaller in the hearing-impaired children. Finally, a smaller acoustic differentiation between the vowels was observed in children with hearing impairment. The results show that even after 5 years of device use, the acoustic characteristics of the vowels in hearing-assisted children remain significantly different as compared to their NH peers.

    On the basis of certain fundamental data on the maturation processes of the central auditory pathways in early childhood the importance of early intervention with hearing aids is discussed and emphasized. Pathological hearing, that is acoustical deprivation in early childhood will influence the maturation process. Very often speech development is delayed if diagnosis and therapy or rehabilitation are not early enough. Anamnesis, early diagnosis and clinical differential diagnosis are required before a hearing aid can be fitted. Selection criteria and adjustment parameters are discussed, showing that the hearing aid fitting procedure must be embedded in a complex matrix of requirements related to the development of speech as well as to the cognitive, emotional and social development of the child. As a rule, finding and preparing the "best" hearing aids (binaural fitting is obligatory) for a child is a long and often difficult process, which can only be performed by specialists who are pedo-audiologists. After the binaural fitting of hearing aids an intensive hearing and speech education in close cooperation between parents, pedo-audiologist and teacher must support the whole development of the child.

    To assess the hearing impairment in people over 60 years old using hearing aids. This was a single-center study, but it is planned to extend it further to the whole country. The study was focused on patients with hearing aids. During the assessment 57 people were included in the observation in order to control the status of their hearing loss and benefit from traditional hearing aids as well as the possibility to apply the auditory implants in case of a little benefit from hearing aids. The otoscopy and pure tone audiometry were performed as well as the questionnaires on demographic and epidemiological data of patients were collected as well as the quality of their life with hearing aids was subjectively assessed. The results show that 91% of patients have sensorineural hearing loss (SHL), the remaining 9%--severe mixed hearing loss. Severe SHL was found in 22 patients, the moderate hearing loss was observed in 37%, and the profound SHL was the case in 5 patients. Minimal SHL was observed in 7% of patients (n=4). More than 73% of the study subjects were male (n=38). The average age of the patients who completed the survey was 74 years old. Thirty-five patients used their hearing aid over 3 years and less than 70% of them used it every day all day. Hearing aid was not actively used by 10 patients. Over the last year 51.92% of the patients underwent a hearing examination. The bone anchored hearing aid was suggested to 2% of subjects and the cochlear implant was offered to 10 patients. The data analysis shows the need to educate and inform the elderly about alternative methods of hearing loss treatment. Copyright © 2013 Polish Otorhinolaryngology - Head and Neck Surgery Society.

    Introduction: Hearing impairment remains the main occupational health problem in the manufacturing industry, and its contributing factors have not been well controlled. Methods: Unmatched case control and comparative studies were carried out among fertilizer factory workers in Sarawak with the aim of determining contributing factors for hearing impairment. Respondents consisted of 49 cases that were diagnosed from 2005 to 2008 with 98 controls from the same work places. Chi-square test and Mann-Whitney test were used in a univariate analysis to determine the association between hearing impairment and the contributing risks being studied. Results: The results of the univariate analysis showed that hearing impairment was significantly (p<0.05) associated with older age, lower education level, high smoking dose, high occupational daily noise dose, longer duration of service, infrequent used of hearing protection device (HPD), and low perception of sound on HPD usage. Multivariate logistic regression of hearing impairment after controlling for age found the following five variables: occupational daily noise dose ≥50% (OR 3.48, 95% CI 1.36-8.89), ≥15 years of services (OR 2.92, 95% CI 1.16-7.33), infrequent use of HPD (OR 2.79, 95% CI 1.15-6.77), low perception of sound on HPD (POR 2.77, 95% CI 1.09-6.97), and smoking more than 20 packs per year (OR 4.71, 95% CI 1.13-19.68). Discussion: In conclusion, high occupational noise exposure level, longer duration of service, low perception of sound on HPD, infrequent used of HPD, and smoking more than 20 packs per year were the contributing factors to hearing impairment, and appropriate intervention measures should be proposed and taken into considerations.

    The aim of present study is to evaluate and compare speech intelligibility in hearing impaired children with cochlear implants (CI) and hearing aid (HA) users and children with normal hearing (NH). The sample consisted of 45 Persian-speaking children aged 3 to 5-years-old. They were divided into three groups, and each group had 15, children, children with CI and children using hearing aids in Hamadan. Participants was evaluated by the test of speech intelligibility level. Results of ANOVA on speech intelligibility test showed that NH children had significantly better reading performance than hearing impaired children with CI and HA. Post-hoc analysis, using Scheffe test, indicated that the mean score of speech intelligibility of normal children was higher than the HA and CI groups; but the difference was not significant between mean of speech intelligibility in children with hearing loss that use cochlear implant and those using HA. It is clear that even with remarkabkle advances in HA technology, many hearing impaired children continue to find speech production a challenging problem. Given that speech intelligibility is a key element in proper communication and social interaction, consequently, educational and rehabilitation programs are essential to improve speech intelligibility of children with hearing loss.

    Despite evidence that hearing aids can improve the social and psychological functioning of older hearing-impaired adults, hearing aid uptake is low. High cost of hearing aids and poor access to audiology services in rural areas are potential barriers to hearing aid acquisition. Methods of hearing aid delivery deviating from the traditional clinician-based model have been available to consumers for many years. One such method is Internet hearing aid sales. However, research exploring Internet-based hearing aid delivery, as a method to improve hearing aid uptake in this population, is limited. The purpose of this study was to explore the perceptions of older hearing aid users (aged ≥65 yr) toward Internet-based hearing aid delivery. A qualitative approach was adopted to investigate older adults' perceptions of buying hearing aids online. The sample consisted of 18 participants aged between 64 and 81 yr. Fourteen men and four women participated in this study. Participants were all experienced hearing aid users. Face-to-face semistructured interviews were conducted. An interview schedule guided the interview. Interviews were recorded with a voice recorder and transcribed verbatim. Thematic analysis of the data was carried out. Seven main themes emerged from the data. A general lack of awareness, but willingness to learn more about Internet hearing aid sales, was found. Two perceived benefits of Internet-based hearing aid delivery were identified: lower cost of hearing aids and greater convenience or physical accessibility. Numerous concerns and limitations were communicated. Concerns regarding the availability of clinical procedures, such as hearing tests, obtaining the correct-sized earmolds, and fine-tuning of hearing aids, were expressed. Participants conveyed distrust in online retailers. However, trust in and a preference for audiologists' expertise, which was not perceived to be available online, was found. Participants further conveyed a preference for face

    Data compiled by the US Equal Employment Opportunity Commission (EEOC), in its Integrated Mission System, provide documentation regarding the employment discrimination experience of Americans who are deaf or hard of hearing. This paper presents an analysis of 8,936 allegations filed by persons with hearing impairment and closed by EEOC between July 26, 1992 and September 30, 2003, as compared to 165,674 allegations filed by individuals with other physical or sensory disabilities. The investigators compare and contrast demographic characteristics of Charging Parties, characteristics of Respondents, the nature of allegations, and the outcomes of the allegations in order to illustrate how these variables differ between the two groups, herein referred to as HEARING (deaf, hard of hearing, or other hearing impairment) and GENDIS (general disability). Most allegations derived from both groups were filed against larger Respondents (those with 500+ workers). The most common allegation issues in the HEARING group involved matters of discharge, reasonable accommodation, and hiring. Outcomes derived from HEARING allegations were more likely to result in merit resolutions when compared to GENDIS, by a 25% to 21% margin.

  3. Recognition of sine wave modeled consonants by normal hearing and hearing-impaired individuals

    NASA Astrophysics Data System (ADS)

    Balachandran, Rupa

    Sine wave modeling is a parametric tool for representing the speech signal with a limited number of sine waves. It involves replacing the peaks of the speech spectrum with sine waves and discarding the rest of the lower amplitude components during synthesis. It has the potential to be used as a speech enhancement technique for hearing-impaired adults. The present study answers the following basic questions: (1) Are sine wave synthesized speech tokens more intelligible than natural speech tokens? (2) What is the effect of varying the number of sine waves on consonant recognition in quiet? (3) What is the effect of varying the number of sine waves on consonant recognition in noise? (4) How does sine wave modeling affect the transmission of speech feature in quiet and in noise? (5) Are there differences in recognition performance between normal hearing and hearing-impaired listeners? VCV syllables representing 20 consonants (/p/, /t/, /k/, /b/, /d/, /g/, /f/, /theta/, /s/, /∫/, /v/, /z/, /t∫/, /dy/, /j/, /w/, /r/, /l/, /m/, /n/) in three vowel contexts (/a/, /i/, /u/) were modeled with 4, 8, 12, and 16 sine waves. A consonant recognition task was performed in quiet, and in background noise (+10 dB and 0 dB SNR). Twenty hearing-impaired listeners and six normal hearing listeners were tested under headphones at their most comfortable listening level. The main findings were: (1) Recognition of unprocessed speech was better that of sine wave modeled speech. (2) Asymptotic performance was reached with 8 sine waves in quiet for both normal hearing and hearing-impaired listeners. (3) Consonant recognition performance in noise improved with increasing number of sine waves. (4) As the number of sine waves was decreased, place information was lost first, followed by manner, and finally voicing. (5) Hearing-impaired listeners made more errors then normal hearing listeners, but there were no differences in the error patterns made by both groups.

    Although recent studies show that age-related hearing impairment is associated with cerebral changes, data from a population perspective are still lacking. Therefore, we studied the relation between hearing impairment and brain volume in a large elderly cohort. From the population-based Rotterdam Study, 2,908 participants (mean age 65 years, 56% female) underwent a pure-tone audiogram to quantify hearing impairment. By performing MR imaging of the brain we quantified global and regional brain tissue volumes (total brain volume, gray matter volume, white matter (WM) volume, and lobe-specific volumes). We used multiple linear regression models, adjusting for age, sex, head size, time between hearing test and MR imaging, and relevant cognitive and cardiovascular covariates. Furthermore, we performed voxel-based morphometry to explore sub-regional differences. We found that a higher pure-tone threshold was associated with a smaller total brain volume [difference in standardized brain volume per decibel increase in hearing threshold in the age-sex adjusted model: -0.003 (95% confidence interval -0.004; -0.001)]. Specifically, WM volume was associated. Both associations were more pronounced in the lower frequencies. All associations were consistently present in all brain lobes in the lower frequencies and in most lobes in the higher frequencies, and were independent of cognitive function and cardiovascular risk factors. In voxel-based analyses we found associations of hearing impairment with smaller white volumes and some smaller and larger gray volumes, yet these were statistically non-significant. Our findings demonstrate that hearing impairment in elderly is related to smaller total brain volume, independent of cognition and cardiovascular risk factors. This mainly seems to be driven by smaller WM volume, throughout the brain. PMID:28163683

    Several studies have focused on the potential impact of children's hearing loss on learning and development. Recently, numerous teenage students have been found to be fond of listening to music on personal devices and participating in recreational music activities. The objective of this study was to investigate teenage students' hearing impairment, their experience with recreational noise exposure, and their self-reported hearing. The participants were 1878 first-year students at a university in Taiwan. The result of the pure tone audiometry test showed that 11.9% of the participants had one or two ears with a hearing threshold over 25 dB. Over the past year, approximately 80.9% of the participants had taken part in at least one loud-noise recreational activity, and 90.9% of the participants were in the habit of using earphones. Among the participants, 190 students with a high level of recreational noise exposure were assigned to the exposure group, and 191 students with a low level of recreational noise exposure constituted the control group. The exposure group had more hearing problems than the control group, but no significant difference existed between the two groups in the pure tone audiometry test (p=0.857). It is suggested that the schools should reinforce hearing health education and proactively provide intervention measures, such as hearing tests, evaluation of noise exposure, and hearing protection.

    The purpose of this study was to describe the experiences of coping with demanding auditory situations in everyday life from the perspective of individuals with severe-profound hearing impairment. Seventeen individuals (11 women and 6 men), with post-lingual severe-profound hearing impairment participated in the study. All were patients at the Department of Audiology, Sahlgrenska University Hospital in Göteborg, Sweden. Inclusion criteria were a hearing impairment exceeding 70 dB HL at the frequency of 1 kHz in the better ear, and full-time employment. Data were assessed by in-depth interviews lasting about one hour. The interviews were transcribed verbatim and analysed line-by-in line in accordance with the grounded theory tradition. Six theoretical constructs, or categories, were grounded in the data. These categories were labelled 'coaching', 'belonging to two worlds', 'self-efficacy', 'hardiness' and 'directing coping strategies'. In a grounded theory the central phenomenon on which all the other categories are integrated is known as the 'core category'. The core category, which emerged in the present study, was labelled 'finding flow and entering a positive circle'. This was described as a condition necessary for successful coping with the demanding situation of being a profoundly hearing-impaired person working full-time. According to the core category, there is a small 'margin' within the positive circle (a space where smaller mistakes may occur). However, if mistakes are too severe, or too many, individuals will no longer find flow in the positive circle, rather they enter a negative circle. In the present study subjects' personalities were characterized by hardiness. It is suggested that coaching behaviour and the hearing-impaired individuals' personality dispositions of hardiness and self-efficacy function as resistance resources, buffering stressful events in everyday life.

    Programmes for early childhood childhood hearing impairment identification allows to quickly start the appropriate hearing aid fitting and rehabilitation process; nevertheless, a large number of patients do not join the treatment program. The goal of this article is to present the results of a strategic review of the strengths, weaknesses, opportunities and threats connected with the audiologic/prosthetic/language follow-up process of children with bilateral permanent hearing impairment. Involving small children, the follow-up includes the involvement of specialised professionals of a multidisciplinary team and a complex and prolonged multi-faced management. Within the framework of the Italian Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", the purpose of this analysis was to propose recommendations that can harmonise criteria for outcome evaluation and provide guidance on the most appropriate assessment methods to be used in the follow-up course of children with permanent hearing impairment. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    Hearing impairment is a recognized cause of emotional and psychological disturbances worldwide, however little is known about this condition in Nigeria. The aim of this study is to compare the prevalence of psychopathology between hearing impaired adolescents and healthy adolescents. Students attending two special schools for the hearing impaired were assessed for psychopathology with the help of a trained signer and their teacher, using the International Classification of Diseases Diagnostic Criteria (ICD 10). Fifty two hearing impaired students and 52 age and sex matched controls from the same school were also interviewed using the same instrument. The mean age of the hearing impaired students was 16 (sd=3.8), while for the controls the mean age was 16 (sd=2.5). Psychopathology was present in 10 (19%) of the hearing impaired adolescents compared to 2 (4%) among the control group, this difference was statistically significant (χ(2)=4.62 p=0.03). The most common diagnosis was generalized anxiety disorder 4 (8%), followed by depression 2 (4%). Years spent in school (t=4.81, p=0.001), primary guardian (χ(2)=18.3, p=0.001) and mean income of guardian (t=7.10, p=0.001) were all significantly different between the two groups. Psychopathology is relatively common in this population. Proper assessment and treatment should be made available for this population group. A limitation to this study is communication difficulty which made only a third party assessment possible; this may affect the generalizability of the findings. Copyright © 2015 Elsevier B.V.

    Preminger, Jill E; Oxenbøll, Maria; Barnett, Margaret B; Jensen, Lisbeth D; Laplante-Lévesque, Ariane

    2015-01-01

    This paper describes how trust is promoted in adults with hearing impairment within the context of hearing healthcare (HHC) service delivery. Data were analysed from a previously published descriptive qualitative study that explored perspectives of adults with hearing impairment on hearing help-seeking and rehabilitation. Interview transcripts from 29 adults from four countries with different levels of hearing impairment and different experience with the HHC system were analysed thematically. Patients enter into the HHC system with service expectations resulting in a preconceived level of trust that can vary from low to high. Relational competence, technical competence, commercialized approach, and clinical environment (relevant to both the clinician and the clinic) influence a patient's resulting level of trust. Trust is evolving rather than static in HHC: Both clinicians and clinics can promote trust. The characteristics of HHC that engender trust are: practicing good communication, supporting shared decision making, displaying technical competence, offering comprehensive hearing rehabilitation, promoting self-management, avoiding a focus on hearing-aid sales, and offering a professional clinic setting.

    The objective of the present study was to elucidate the incidence of mycoplasma infection concomitant with sensorineural hearing impairment and its clinical manifestations with special reference to the methods for its diagnostics and treatment. The main method for the detection of mycoplasma infection is PCR in real time and the auxiliary one is the immunoenzymatic assay. The study revealed mycoplasma infection in 15 (13.9%) of the examined patients. The results of our investigations give evidence of the necessity to further study the clinical symptoms of mycoplasma infection associated with sensorineural hearing impairment and to search for the methods of the management of this condition.

    2007-01-01

    The present study investigated whether moderate amounts of computer-assisted speech training can improve the speech recognition performance of hearing-impaired children. Ten Mandarin-speaking children (3 hearing aid users and 7 cochlear implant users) participated in the study. Training was conducted at home using a personal computer for half an hour per day, 5 days per week, for a period of 10 weeks. Results showed significant improvements in subjects' vowel, consonant, and tone recognition performance after training. The improved performance was largely retained for 2 months after training was completed. These results suggest that moderate amounts of auditory training, using a computer-based auditory rehabilitation tool with minimal supervision, can be effective in improving the speech performance of hearing-impaired children.

    According to the scientific reports the postural stability is inseparably associated with hearing organ's correct functioning. The aim of the study was to evaluate the degree of disorders occurring in balance reactions in this group of children with profound hearing loss compared to their healthy peers. The study worked with a total of 228 children, including 65 who are deaf (DCH) and 163 subjects without any hearing deficits (CON) in the control group. Stabilometric measurements were performed with the use of a force distribution platform. The results indicate statistically significant differences in terms of one parameter (the total path length) recorded in the test with the eyes open and a whole range of parameters recorded when the subjects had their eyes closed (the width, height, and area of the ellipse, the total path length, and the horizontal and vertical sway). The study results showed better values of the static balance parameters in deaf children as compared to their peers without hearing disorders and the differences were particularly evident in the test with the subject's eyes closed. The results suggest significantly better processing of sensory stimuli in postural reactions particularly from propioception, and to a lesser extent, from the vision system observed in the subjects as compared to their peers in the control group.

    Although the need for better-skilled workers has been signaled by the marketplace, people with hearing impairments generally are employed in unskilled or semiskilled jobs. They are, therefore, at heightened risk of unemployment and underemployment. Compounding this risk are the levels of vocational preparation and job awareness of adolescents with hearing impairments, which are generally considered inadequate. With a view to improving prevocational programs for hearing impaired adolescents, the researcher collected information on career awareness and vocational maturity. Significant differences were identified between hearing impaired and hearing adolescents on a range of career measures. In particular, adolescents with hearing impairments were identified as having less career awareness.

    2000-01-01

    The frequency of three mitochondrial point mutations, 1555A→G, 3243A→G, and 7445A→G, known to be associated with hearing impairment, was examined using restriction fragment length polymorphism (RFLP) analysis in two Japanese groups: (1) 319 unrelated SNHL outpatients (including 21 with aminoglycoside antibiotic injection history), and (2) 140 cochlear implantation patients (including 22 with aminoglycoside induced hearing loss). Approximately 3% of the outpatients and 10% of the cochlear implantation patients had the 1555A→G mutation. The frequency was higher in the patients with a history of aminoglycoside injection (outpatient group 33%, cochlear implantation group 59%). One outpatient (0.314%) had the 3243A→G mutation, but no outpatients had the 7445A→G mutation and neither were found in the cochlear implantation group. The significance of the 1555A→G mutation, the most prevalent mitochondrial mutation found in this study of a hearing impaired population in Japan, among subjects with specific backgrounds, such as aminoglycoside induced hearing loss, is evident.

  1. Binaural pitch perception in normal-hearing and hearing-impaired listeners.

    PubMed

    Santurette, Sébastien; Dau, Torsten

    2007-01-01

    The effects of hearing impairment on the perception of binaural-pitch stimuli were investigated. Several experiments were performed with normal-hearing and hearing-impaired listeners, including detection and discrimination of binaural pitch, and melody recognition using different types of binaural pitches. For the normal-hearing listeners, all types of binaural pitches could be perceived immediately and were musical. The hearing-impaired listeners could be divided into three groups based on their results: (a) some perceived all types of binaural pitches, but with decreased salience or musicality compared to normal-hearing listeners; (b) some could only perceive the strongest pitch types; (c) some were unable to perceive any binaural pitch at all. The performance of the listeners was not correlated with audibility. Additional experiments investigated the correlation between performance in binaural-pitch perception and performance in measures of spectral and temporal resolution. Reduced frequency discrimination appeared to be linked to poorer melody recognition skills. Reduced frequency selectivity was also found to impede the perception of binaural-pitch stimuli. Overall, binaural-pitch stimuli might be very useful tools within clinical diagnostics for detecting specific deficiencies in the auditory system.

  2. Laryngeal Aerodynamics in Children with Hearing Impairment versus Age and Height Matched Normal Hearing Peers.

    PubMed

    2013-01-01

    Lack of proper auditory feedback in hearing-impaired subjects results in functional voice disorder. It is directly related to discoordination of intrinsic and extrinsic laryngeal muscles and disturbed contraction and relaxation of antagonistic muscles. A total of twenty children in the age range of 5-10 years were considered for the study. They were divided into two groups: normal hearing children and hearing aid user children. Results showed a significant difference in the vital capacity, maximum sustained phonation, and fast adduction abduction rate having equal variance for normal and hearing aid user children, respectively, but no significant difference was found in the peak flow value with being statistically significant. A reduced vital capacity in hearing aid user children suggests a limited use of the lung volume for speech production. It may be inferred from the study that the hearing aid user children have poor vocal proficiency which is reflected in their voice. The use of voicing component in hearing impaired subjects is seen due to improper auditory feedback. It was found that there was a significant difference in the vital capacity, maximum sustained phonation (MSP), and fast adduction abduction rate and no significant difference in the peak flow.

    Previous research, mostly reliant on self-reports, has indicated that hearing aid (HA) use is related to the degree of hearing impairment (HI). No large-scale investigation of the relationship between data-logged HA use and HI has been conducted to date. This study aimed to investigate if objective measures of overall daily HA use and HA use in various listening environments are different for adults with mild HI compared to adults with moderate HI. This retrospective study used data extracted from a database of fitting appointments from an international group of HA providers. Only data from the participants' most recent fitting appointment were included in the final dataset. A total of 8,489 bilateral HA fittings of adults over the age of 18 yr, conducted between January 2013 and June 2014, were included. Participants were subsequently allocated to HI groups, based on British Society of Audiology and American Speech-Language-Hearing Association audiometric descriptors. Fitting data from participating HA providers were regularly transferred to a central server. The data, with all personal information except age and gender removed, contained participants' four-frequency average (at 500, 1000, 2000, and 4000 Hz) as well as information on HA characteristics and usage. Following data cleaning, bivariate and post hoc statistical analyses were conducted. The total sample of adults' average daily HA use was 8.52 hr (interquartile range [IQR] = 5.49-11.77) in the left ear and 8.51 hr (IQR = 5.49-11.72) in the right ear. With a few exceptions, there were no statistical differences between hours of HA use for participants with mild HI compared to those with moderate impairment. Across all mild and moderate HI groups, the most common overall HA usage was between 8 and 12 hr per day. Other factors such as age, gender, and HA style also showed no relationship to hours of use. HAs were used, on average, for 7 hr (IQR = 4.27-9.96) per day in quiet and 1 hr (IQR = 0.33-1.41) per

    As people grow older, speech perception difficulties become highly prevalent, especially in noisy listening situations. Moreover, it is assumed that speech intelligibility is more affected in the event of background noises that induce a higher cognitive load, i.e., noises that result in informational versus energetic masking. There is ample evidence showing that speech perception problems in aging persons are partly due to hearing impairment and partly due to age-related declines in cognition and suprathreshold auditory processing. In order to develop effective rehabilitation strategies, it is indispensable to know how these different degrading factors act upon speech perception. This implies disentangling effects of hearing impairment versus age and examining the interplay between both factors in different background noises of everyday settings. To that end, we investigated open-set sentence identification in six participant groups: a young (20-30 years), middle-aged (50-60 years), and older cohort (70-80 years), each including persons who had normal audiometric thresholds up to at least 4 kHz, on the one hand, and persons who were diagnosed with elevated audiometric thresholds, on the other hand. All participants were screened for (mild) cognitive impairment. We applied stationary and amplitude modulated speech-weighted noise, which are two types of energetic maskers, and unintelligible speech, which causes informational masking in addition to energetic masking. By means of these different background noises, we could look into speech perception performance in listening situations with a low and high cognitive load, respectively. Our results indicate that, even when audiometric thresholds are within normal limits up to 4 kHz, irrespective of threshold elevations at higher frequencies, and there is no indication of even mild cognitive impairment, masked speech perception declines by middle age and decreases further on to older age.

    Hearing impairments and hearing loss cause deficits in communication ability and represent relevant participation restrictions according to the International Classification of Functioning, Disability and Health (ICF). In order to counteract these participation restrictions, particularly in the workplace, several acts have been passed in Germany including SGB IX and UN-BRK. The implementation of these laws in the federal states Saxony, Saxony-Anhalt, and Thuringia is presented from the perspective of hearing-impaired employees. In the GINKO study, conducted in cooperation with self-help organizations, a standardized written questionnaire with items about the workplace was administered to employed persons with hearing impairments. The questionnaire was also available online with sign language. Overall, 3189 severely disabled hearing-impaired working persons responded to the GINKO survey, of whom n = 260 (8.3 %) were from Saxony, n = 53 (1.7 %) from Saxony-Anhalt, and n = 62 (1.9 %) from Thuringia. The majority of participants reported that they did not (yet) have an accessible workplace and that assistive services were not available to all hearing-impaired employees. This was true overall and in the three individual states. There are still considerable deficits in the implementation of legally required possibilities. No statistically significant differences exist between the three federal states in terms of utilization of legally required assistive services in the workplace or the accessibility of the workplace to hearing-impaired employees. Causes for this might be found in insufficient information regarding legal possibilities available to hearing-impaired employees. Therefore, information about state-wide self-help organizations is important to encourage participation in working life in accordance with ICF after successful medical treatment.

    Hearing loss is a barrier to speech and social and cognitive development. This can be especially pronounced in children living in low- and middle-income countries with limited resources. To determine the feasibility, durability and social impact of ComCare GLW solar-powered hearing aids provided for Vietnamese children with hearing impairment. A retrospective review of data from an international, multi-discipline humanitarian visit was performed. Hearing aids were given to 28 children enrolled at the Khoai Chau Functional Rehabilitation School, Hung Yen Province, Vietnam. Device inspection and observational assessments were performed by teachers using a modified Parents' Evaluation of Aural/Oral Performance of Children and an Infant Hearing Program Amplification Benefit Questionnaire. Qualitative interviews were undertaken to assess the study aims. Hearing aids were well tolerated for use during regular school hours. All units remained functional during the study period (12 months). Teachers noted increased student awareness and responsiveness to surrounding sounds, but the degree of response to amplification varied between children. There was no significant improvement in speech development as all subjects had prelingual deafness. Teachers felt confident in troubleshooting any potential device malfunction. A solar-powered hearing aid may be a viable option for children in low- and middle-income countries. This study demonstrates that device distribution, maintenance and function can be established in countries with limited resources, while providing feasibility data to support future studies investigating how similar devices may improve the quality of life of those with hearing loss.

  7. Temporal modulation transfer functions obtained using sinusoidal carriers with normally hearing and hearing-impaired listeners.

    Temporal modulation transfer functions were obtained using sinusoidal carriers for four normally hearing subjects and three subjects with mild to moderate cochlear hearing loss. Carrier frequencies were 1000, 2000 and 5000 Hz, and modulation frequencies ranged from 10 to 640 Hz in one-octave steps. The normally hearing subjects were tested using levels of 30 and 80 dB SPL. For the higher level, modulation detection thresholds varied only slightly with modulation frequency for frequencies up to 80 Hz, but decreased for high modulation frequencies. The decrease can be attributed to the detection of spectral sidebands. For the lower level, thresholds varied little with modulation frequency for all three carrier frequencies. The absence of a decrease in the threshold for large modulation frequencies can be explained by the low sensation level of the spectral sidebands. The hearing-impaired subjects were tested at 80 dB SPL, except for two cases where the absolute threshold at the carrier frequency was greater than 70 dB SPL; in these cases a level of 90 dB was used. The results were consistent with the idea that spectral sidebands were less detectable for the hearing-impaired than for the normally hearing subjects. For the two lower carrier frequencies, there were no large decreases in threshold with increasing modulation frequency, and where decreases did occur, this happened only between 320 and 640 Hz. For the 5000-Hz carrier, thresholds were roughly constant for modulation frequencies from 10 to 80 or 160 Hz, and then increased monotonically, becoming unmeasurable at 640 Hz. The results for this carrier may reflect "pure" effects of temporal resolution, without any influence from the detection of spectral sidebands. The results suggest that temporal resolution for deterministic stimuli is similar for normally hearing and hearing-impaired listeners.

    Serious hearing problems appear in approximately one in 1000 newborns. In 2000, the Joint Committee on Infant Hearing defined a list of risk factors for neonatal hearing impairment relating to health, physical characteristics and family history. The aim of this study is to determine which personal, environmental and social factors are associated with the prevalence of congenital hearing impairment (CHI). The entire population of 103,835 term newborns in Flanders, Belgium, was tested by a universal neonatal hearing screening (UNHS) programme using automated auditory brainstem responses (AABR). In the case of a positive result, a CHI diagnosis was verified in specialized referral centres. Socio-demographic risk factors were investigated across the entire population to study any relationship with CHI. The prevalence of bilateral CHI of 35 dB nHL (normal hearing level) or more was 0.87/1000 newborns. The sensitivity and specificity of the screening test were 94.02 and 99.96%, respectively. The socio-demographic factors of gender, birth order, birth length, feeding type, level of education and origin of the mother were found to be independent predictors of CHI. The socio-demographic factors found to be associated with CHI extend the list of classic risk factors as defined by the American Academy of Pediatrics (AAP). Assessment of these additional factors may alert the treating physician to the increased risk of newborn hearing impairment and urge the need for accurate follow-up. Moreover, this extended assessment may improve decision making in medical practice and screening policy.

    Self-assessment tools have proven to be useful in everyday practice in the audiology field, mostly in developed countries. There is a lack of such tests in Spanish. Our objective was to construct an inventory that could help us to identify elderly non-institutionalized patients who need an audiological assessment; we did not intend to identify or qualify emotional or social/situational reactions towards hearing handicap. As a prototype we initially translated, adapted and standardized the Hearing Handicap Inventory for the Elderly. This questionnaire was given to 60 elderly subjects. The performance on each question was compared with the audiometric results. After selecting useful and suitable questions, modifying some others and eliminating those with a poor performance, a new inventory in Spanish was developed. This final version was then tested in 63 elderly subjects. Very good scores were obtained for each question. An 'easy-to-use' rule is proposed in order to identify those patients who need to be audiologically tested. A brief meta-linguistic analysis is made on semantic and cultural factors that contributed to good translation and cultural adaptation.

    The aim of this study was to evaluate health-related quality of life (HRQoL) in adults with hearing impairment in Finland before and after hearing rehabilitation. The study was prospective with hearing-aid rehabilitation as the intervention. The data was collected, using the 15D instrument, before and six months after hearing-aid rehabilitation. The data was analysed using t-tests and multiple linear regression methods. The study sample included 949 adults with hearing impairment, and the control group included a sample of age- and gender-standardized general population. The study population had significantly poorer HRQoL on most dimensions of the 15D when compared to the control group both before and after hearing-aid rehabilitation. Hearing-aid rehabilitation resulted in improved mean scores on the dimensions of hearing and in the overall 15D score that were statistically significant, although the mean improvement in the overall score was marginal. Self-reported hearing ability can better predict the change in HRQoL, as a result of a hearing aid, when compared with measured hearing sensitivity. The study supports the hypothesis that on average, use of a unilateral hearing aid results in improved subjective hearing and marginal improvement in HRQoL in adults with hearing impairment.

    This study, involving 215 students and 63 teachers, addressed three concerns related to mainstreaming for hearing imparied students: the selection process, the difference between a mainstream placement with an interpreter and a self-contained placement, and the quality of the educational experience. Almost half of the variance in achievement between the two settings is described. Three conclusions can be drawn. First, student background factors are a primary determinant of achievement. Second, mainstreaming with an interpreter has no specific effect on achievement for hearing impaired students. Third, the quality of instruction is the prime determinant of achievement, regardless of placement.

    2015-01-01

    The aim of this article is to address the issue of nightmares in the deaf population, given that there are no documented studies on this matter to the best of our knowledge. The study of nightmares in the deaf population is of high relevance given their specific characteristics (impossibility of verbalisation) and the lack of studies with this population. Nightmares are dreams of negative content that trigger an awakening associated with a rapid return to a full state of alert and a persistent feeling of anxiety and fear, which may cause significant distress. Various studies show that the deaf population has dreams with more negative imagery and emotions, are more exposed to interpersonal traumas and have higher rates of dissociation, than hearing people. These concepts seem to be connected given that, in the presence of traumatic events, dissociation may act as a defence mechanism and nightmares may operate as an adaptive coping strategy.

    Understanding underlying pathological mechanisms is prerequisite for a sensible design of protective therapies against hearing loss. The triad of age-related, noise-generated, and drug-induced hearing loss displays intriguing similarities in some cellular responses of cochlear sensory cells such as a potential involvement of reactive oxygen species (ROS) and apoptotic and necrotic cell death. On the other hand, detailed studies have revealed that molecular pathways are considerably complex and, importantly, it has become clear that pharmacological protection successful against one form of hearing loss will not necessarily protect against another. This review will summarize pathological and pathophysiological features of age-related hearing impairment (ARHI) in human and animal models and address selected aspects of the commonality (or lack thereof) of cellular responses in ARHI to drugs and noise.

    Summary The cochlear microphonic is a receptor potential believed to be generated primarily by outer hair cells. Its detection in surface recordings has been considered a distinctive sign of outer hair cell integrity in patients with auditory neuropathy. This report focuses on the results of an analysis performed on cochlear microphonic recorded by transtympanic electrocochleography in response to clicks in 502 subjects with normal hearing threshold or various degrees of hearing impairment, and in 20 patients with auditory neuropathy. Cochlear microphonics recorded in normally-hearing and hearing-impaired ears showed amplitudes decreasing by the elevation of compound action potential Cochlear microphonic responses were clearly detected in ears with profound hearing loss. After separating recordings according to the presence or absence of central nervous system pathology (CNS+ and CNS-, respectively), cochlear microphonic amplitude was significantly higher in CNS+ than in CNS- subjects with normally-hearing ears and at 70 dB nHL compound action potential threshold. Cochlear microphonic responses were detected in all auditory neuropathy patients, with similar amplitudes and thresholds to those calculated for normally-hearing CNS- subjects. Cochlear microphonic duration was significantly higher in auditory neuropathy and normally-hearing CNS+ patients compared to CNS- subjects. Our results show that: 1. cochlear microphonic detection is not a distinctive feature of auditory neuropathy; 2. CNS+ subjects showed enhancement in cochlear microphonic amplitude and duration, possibly due to efferent system dysfunction; 3. long-lasting, high frequency cochlear microphonics with amplitudes comparable to those obtained from CNS- ears were found in auditory neuropathy patients. This could result from a variable combination of afferent compartment lesion, efferent system dysfacilitation and loss of outer hair cells. PMID:16886850

    A self-fitting hearing aid, designed to be assembled and programmed without audiological or computer support, could bring amplification to millions of people in developing countries, who remain unaided due to the lack of a local, professional, audiological infrastructure. The ability to assemble and insert a hearing aid is fundamental to the successful use of a self-fitting device. In this study, the management of such tasks was investigated. Eighty older, urban-dwelling, hearing-impaired adults in a developed country were asked to follow a set of written, illustrated instructions to assemble two slim-fit behind-the-ear hearing aids. Participants were allowed to access assistance with the task from an accompanying partner. A range of personal and audiometric variables was measured through the use of structured questionnaires and standardized tests of health literacy, cognitive function, and manual dexterity. The results showed that 99% of participants were able to complete the hearing aid assembly task, either on their own or with assistance. Health literacy, or the ability to read and understand health-related text, and gender most strongly influenced participants’ ability to complete the assembly task independently and accurately. Higher levels of health literacy were associated with an increased likelihood of independent and successful task completion. Male participants were more likely to complete the task on their own, while female participants were more likely to assemble the device without errors. The results of this study will inform future work regarding development of educational material for the self-fitting hearing aid as well as candidacy for such a device. PMID:22200734

    The objective of this study was to evaluate hearing impairment in patients affected by Parkinson's disease compared with hearing scores observed in normal age- and sex-matched controls. One hundred eighteen consecutive patients with a clinical diagnosis of Parkinson's disease were screened. Severity of motor symptoms and staging were measured with the Unified Parkinson's Disease Rating Scale (section III) and the Hoehn and Yahr scale. Audiometric evaluation consisted of a comprehensive audiologic case history and questionnaire, visual otoscopic examination, acoustic immittance measures (tympanogram and acoustic reflexes), pure tone audiometry, and measurement of brain stem auditory-evoked potentials. Healthy age- and sex-matched subjects were selected as the control group. One hundred six of 118 patients were enrolled. Pure tone audiometry revealed age-dependent high-frequency hearing loss in patients with Parkinson's disease compared with both normative values and values for healthy age- and sex-matched controls (75/106 [71%], χ(2) = 5.959, P = .02; 92/106 [86.8%] vs 60/106 [56.6%], χ(2) = 23.804, P < .001, respectively). Pure tone audiometry scores correlated with Hoehn and Yahr scale scores (P < .05). Brain stem auditory-evoked potentials were normal in all patients. Our patients with Parkinson's disease showed age-dependent peripheral, unilateral, or bilateral hearing impairment. Whether these auditory deficits are intrinsic to Parkinson's disease or secondary to a more complex impaired processing of sensorial inputs occurring over the course of illness remains to be determined. Because α-synuclein is located predominately in the efferent neuronal system within the inner ear, it could affect susceptibility to noise-induced hearing loss or presbycusis. It is feasible that the natural aging process combined with neurodegenerative changes intrinsic to Parkinson's disease might interfere with cochlear transduction mechanisms, thus anticipating presbycusis.

    In elementary school classes, noise during student led activities is often taken as evidence of successful interaction and learning. In this complex social environment of elementary school classrooms, acquisition of complex language and social skills-the focus of activities in early education-is expected to take place in hearing-hostile environments. Communication and language processing in these contexts requires interactive strategies, discourse forms, and syntactic structures different from the educationally desired forms used in acoustically advantageous environments. Recordings were made of the interaction of groups of students in grades 1-3, 5, and 7 during collaborative group work in their regular classrooms. Each student wore microphones at the ear level and head-mounted video cameras. Each group as a whole was also audio- and videotaped and noise level readings were recorded. Analysis of the acoustical and phonological properties of language heard by each student has demonstrated that the language variety used in these noisy and reverberant settings is similar to that of individuals with hearing impairments. This paper reports similarities between the syntactic structures and pragmatic strategies used by hearing impaired children and normally hearing children in noisy contexts.

    Stroke survivors may suffer from a range of hearing impairments that may restrict their participation in postacute rehabilitation programs. Hearing impairment may have a significant impact on listening, linguistic skills, and overall communication of the affected stroke patient. However, no studies sought to systematically characterize auditory function of stroke patients in detail, to establish the different types of hearing impairments in this cohort of patients. Such information would be clinically useful in understanding and addressing the hearing needs of stroke survivors. The present study aimed to characterize and classify the hearing impairments, using a detailed audiological assessment test battery, in order to determine the level of clinical need and inform appropriate rehabilitation for this patient population. A case-control study. Forty-two recruited stroke patients who were discharged from a stroke unit and 40 control participants matched for age. All participants underwent pure-tone audiometry and immittance measurements including acoustic reflex threshold, transient-evoked otoacoustic emissions, auditory-evoked brainstem response, and a central auditory processing assessment battery, performed in a single session. Hearing impairments were classified as peripheral hearing loss (cochlear and neural type), central auditory processing disorder (CAPD), and as a combination of CAPD and peripheral hearing loss. Overall mean hearing thresholds were not significantly different between the control and stroke groups. The most common type of hearing impairment in stroke patients was the combination type, "peripheral and CAPD," in the 61- to 80-yr-old subgroup (in 55%), and auditory processing deficits in 18- to 60-yr-olds (in 40%), which were both significantly higher than in controls. This is the first study to examine hearing function in detail in stroke patients. Given the importance of hearing for the efficiency of communication, it is essential to identify

Two research questions were addressed: Q1) does hearing impairment affect listening effort? and Q2) can hearing aid amplification affect listening effort during speech comprehension? Design: English language articles were identified through systematic searches in PubMed, EMBASE, Cinahl, the Cochrane Library, and PsycINFO from inception to August 2014. References of eligible studies were checked. The Population, Intervention, Control, Outcomes, and Study design strategy was used to create inclusion criteria for relevance. It was not feasible to apply a meta-analysis of the results from comparable studies. For the articles identified as relevant, a quality rating, based on the 2011 Grading of Recommendations Assessment, Development, and Evaluation Working Group guidelines, was carried out to judge the reliability and confidence of the estimated effects. Results: The primary search produced 7017 unique hits using the keywords: hearing aids OR hearing impairment AND listening effort OR perceptual effort OR ease of listening. Of these, 41 articles fulfilled the Population, Intervention, Control, Outcomes, and Study design selection criteria of: experimental work on hearing impairment OR hearing aid technologies AND listening effort OR fatigue during speech perception. The methods applied in those articles were categorized into subjective, behavioral, and physiological assessment of listening effort. For each study, the statistical analysis addressing research question Q1 and/or Q2 was extracted. In seven articles more than one measure of listening effort was provided. Evidence relating to Q1 was provided by 21 articles that reported 41 relevant findings. Evidence relating to Q2 was provided by 27 articles that reported 56 relevant findings. The quality of evidence on both research questions (Q1 and Q2) was very low

    Experience is being gained from evaluating and modifying the acoustical properties and background noise levels of existing classrooms for use by hearing impaired students. Projects include more than 25 schools in public school systems that are mainstreaming handicapped children. Various practical and economic restrictions have led to recommendations for modifications that do not necessarily comply with ANSI S12.60 2002. Examples of real world conditions and practical solutions will be described.

    Legislation for people with disabilities has also changed due to other changes in the law, especially due to the recent ratification of the UN Convention on the Rights of Persons with Disabilities. These laws, in particular the UN Convention on the Rights of Persons with Disabilities, with its inclusion of the right to equitable and universal access to education for people with disabilities and their implementation, are of central importance for students who are impaired. As part of the GINKO (the legislative effect laws have on the professional integration of those who are hard of hearing, people who have gone deaf and those who are deaf through communication and organization; promotion: BMAS) project, the following questions were also brought up for discussion and were investigated: to what extent hearing-impaired students are aware of legislation that benefits them, whether these laws will be implemented, and what factors have an impact on this legal knowledge or its implementation. Overall, 4,825 handicapped individuals with hearing impairments - including n=166 students - took part in the survey. The results of the evaluation of the group of hearing-impaired students indicate that many of them are not informed about laws important to them. It was also found that the knowledge of a law cannot be equated with its implementation. This survey also resulted in a resolve for the future, to demand information about legal options be reinforced, and to adjust this information to fit the needs of specific target groups, e.g. this information could be disseminated through sign language films. On the other hand, these results also apply to higher education, for these institutions to create learning conditions where existing regulatory design options for students with disabilities are implemented, thereby affording students an equal opportunity to participate in higher education. © Georg Thieme Verlag KG Stuttgart · New York.

    Lifestyle including smoking, noise exposure with MP3 player and drinking alcohol are considered as risk factors for affecting hearing synergistically. However, little is known about the association of cigarette smoking with hearing impairment among subjects who carry a lifestyle without using MP3 player and drinking alcohol. We showed here the influence of smoking on hearing among Bangladeshi subjects who maintain a lifestyle devoid of using MP3 player and drinking alcohol. A total of 184 subjects (smokers: 90; non-smokers: 94) were included considering their duration and frequency of smoking for conducting this study. The mean hearing thresholds of non-smoker subjects at 1, 4, 8 and 12 kHz frequencies were 5.63±2.10, 8.56±5.75, 21.06±11.06, 40.79±20.36 decibel (dB), respectively and that of the smokers were 7±3.8, 13.27±8.4, 30.66±12.50 and 56.88±21.58 dB, respectively. The hearing thresholds of the smokers at 4, 8 and 12 kHz frequencies were significantly (p<0.05) higher than those of the non-smokers, while no significant differences were observed at 1 kHz frequency. We also observed no significant difference in auditory thresholds among smoker subgroups based on smoking frequency. In contrast, subjects smoked for longer duration (>5 years) showed higher level of auditory threshold (62.16±19.87 dB) at 12 kHz frequency compared with that (41.52±19.21 dB) of the subjects smoked for 1-5 years and the difference in auditory thresholds was statistically significant (p<0.0002). In this study, the Brinkman Index (BI) of smokers was from 6 to 440 and the adjusted odds ratio showed a positive correlation between hearing loss and smoking when adjusted for age and body mass index (BMI). In addition, age, but not BMI, also played positive role on hearing impairment at all frequencies. Thus, these findings suggested that cigarette smoking affects hearing level at all the frequencies tested but most significantly at extra higher frequencies. PMID:25781179

    We aimed to determine the prospective association between measured hearing impairment, self-reported hearing handicap and hearing aid use with quality of life. 829 Blue Mountains Hearing Study participants (≥ 55 years) were examined between 1997-1999 and 2007-2009. The shortened version of the hearing handicap inventory was administered. Hearing levels were measured using pure-tone audiometry. Quality of life was assessed using the 36-Item Short-Form Survey (SF-36); higher scores reflect better quality of life. Hearing impairment at baseline compared with no impairment was associated with lower mean SF-36 mental composite score 10 years later (multivariable-adjusted p=0.03). Physical composite score and mean scores for seven of the eight SF-36 domains after 10-year follow-up were significantly lower among participants who self-reported hearing handicap at baseline. Differences in the adjusted means between participants with and without hearing handicap ranged from 2.7 (physical composite score) to 10.4 units ('role limitations due to physical problems' domain). Individuals who developed incident hearing impairment compared to those who did not, had adjusted mean scores 9.5- and 7.7-units lower in the 'role limitation due to physical problems', and 'bodily pain' domains, respectively, at the 10-year follow-up. Hearing aid users versus non-users at baseline showed a 1.82-point (p=0.03) and 3.32-point (p=0.01) increase in SF-36 mental composite score and mental health domain over the 10-year follow-up, respectively. Older adults with self-perceived hearing handicap constitute a potential risk group for overall deterioration in quality of life, while hearing aid use could help improve the well-being of hearing impaired adults.

    Objectives The purpose of this study was to assess a new signal-processing strategy, Spatiotemporal Pattern Correction (SPC), for a group of listeners with varying degrees of sensorineural hearing loss. SPC is based on a physiological model of the level-dependent temporal response properties of auditory nerve (AN) fibers in normal and impaired ears. SPC attempts to “correct” AN response patterns by introducing time-varying group delays that differ across frequency channels. Listeners’ speech intelligibility and preference judgments were obtained at different strengths of SPC processing. Design Fifteen listeners, 12 with bilateral sensorineural hearing loss and 3 with normal hearing, participated in this study. Listeners with hearing impairment were separated into 3 groups (mild, moderate, and moderate-to-severe), based on their pure-tone averages at 0.5, 1, 2, and 4 kHz. All preference judgments were made using sentences from the Hearing-In-Noise-Test (HINT). The sentences were processed at five SPC strengths (1.0, 1.1, 1.2, 1.3, and 1.4). At an SPC strength of 1.0, the speech was processed through the SPC signal processor, becoming bandlimited, but no dynamic group delays were added to the signal. On each trial, listeners were presented a single sentence at two different SPC strengths, 1.0 (uncorrected) and a randomly selected SPC strength. Listeners were instructed to identify which of the two sentences they preferred. Sixteen vowel-consonant syllables, a subset of the Nonsense Syllable Test (NST), were used to assess speech intelligibility at three SPC strengths (1.0, 1.1, and 1.2). Listeners were asked to push one of 16 buttons on a response box that corresponded to the vowel-consonant syllable they heard. The moderate-to-severe hearing loss group was also tested using the low-probability sentences of the Speech-Perception-In-Noise (SPIN) test. Results Listeners with normal hearing and listeners with mild hearing loss preferred the quality of uncorrected

    A self-fitting hearing aid, designed to be assembled and programmed without audiological or computer support, could bring amplification to millions of people in developing countries, who remain unaided due to the lack of a local, professional, audiological infrastructure. The ability to assemble and insert a hearing aid is fundamental to the successful use of a self-fitting device. In this study, the management of such tasks was investigated. Eighty older, urban-dwelling, hearing-impaired adults in a developed country were asked to follow a set of written, illustrated instructions to assemble two slim-fit behind-the-ear hearing aids. Participants were allowed to access assistance with the task from an accompanying partner. A range of personal and audiometric variables was measured through the use of structured questionnaires and standardized tests of health literacy, cognitive function, and manual dexterity. The results showed that 99% of participants were able to complete the hearing aid assembly task, either on their own or with assistance. Health literacy, or the ability to read and understand health-related text, and gender most strongly influenced participants' ability to complete the assembly task independently and accurately. Higher levels of health literacy were associated with an increased likelihood of independent and successful task completion. Male participants were more likely to complete the task on their own, while female participants were more likely to assemble the device without errors. The results of this study will inform future work regarding development of educational material for the self-fitting hearing aid as well as candidacy for such a device.

    The purpose of this study was to investigate the effect of symmetrical, asymmetrical and unilateral hearing impairment on music quality perception. Six validated music pieces in the categories of classical music, folk music and pop music were used to assess music quality in terms of its 'pleasantness', 'naturalness', 'fullness', 'roughness' and 'sharpness'. 58 participants with sensorineural hearing loss [20 with unilateral hearing loss (UHL), 20 with bilateral symmetrical hearing loss (BSHL) and 18 with bilateral asymmetrical hearing loss (BAHL)] and 29 normal hearing (NH) subjects participated in the present study. Hearing impaired (HI) participants had greater difficulty in overall music quality perception than NH participants. Participants with BSHL rated music pleasantness and naturalness to be higher than participants with BAHL. Moreover, the hearing thresholds of the better ears from BSHL and BAHL participants as well as the hearing thresholds of the worse ears from BSHL participants were negatively correlated to the pleasantness and naturalness perception. HI participants rated the familiar music pieces higher than unfamiliar music pieces in the three music categories. Music quality perception in participants with hearing impairment appeared to be affected by symmetry of hearing loss, degree of hearing loss and music familiarity when they were assessed using the music quality rating test (MQRT). This indicates that binaural symmetrical hearing is important to achieve a high level of music quality perception in HI listeners. This emphasizes the importance of provision of bilateral hearing assistive devices for people with asymmetrical hearing impairment.

    Cooperative and individualistic learning experiences were compared in terms of their effects on interaction and relationships between hearing and hearing-impaired students. Two contradictory hypotheses were tested--one stating that the effort required for hearing and hearing-impaired students to communicate would lead to frustration, withdrawal, exclusion, and rejection; the other stating that cooperative learning experiences would lead to cross-handicap interpersonal attraction regardless of communication difficulties. Thirty 3rd-grade students (20 hearing and 10 hearing impaired) were assigned to conditions on a stratified, random basis controlling for handicap, sex, and ability level. They participated in the study for 55 min a day for 15 instructional days. The results indicate that subjects involved in cooperative learning experiences performed higher on measures of interaction and interpersonal attraction between hearing and hearing-impaired students than did subjects involved in individualistic learning experiences.

    This study had two aims: (1) to describe the extent of third-party disability in a sample of spouses of older people with hearing impairment, and (2) to investigate factors associated with third-party hearing disability. Third-party disability is defined as the disability and functioning of family members as a result of the health condition of their significant other. One hundred older spouses who had partners with hearing impairment participated. All assessments were self-reported, and included a set of measures (the 36-item Significant Other Scale for Hearing Disability, SOS-HEAR; the Relationship Assessment Scale; and the Significant Other Assessment of Communication) administered to the target population of normally hearing older spouses, and those administered to the hearing impaired partners of the spouses in the study (the Self Assessment of Communication). To address the first aim, descriptive statistics were used to describe the extent of third-party hearing disability in the spouses. To address the second aim, binary logistic regression analysis was used to examine factors associated with third-party hearing disability. Factors investigated were focused on the spouse (e.g., spouse perception of relationship satisfaction) and on the partners with hearing impairment (e.g., partners' level of hearing impairment). Most spouses (98%) reported some degree of third-party hearing disability on at least one item of the SOS-HEAR, with the majority reporting a mild disability. Three risk factors were found to be significantly associated with severe or complete third-party disability: lower relationship satisfaction as reported by the spouse (Relationship Assessment Scale), spousal age difference, and spouse perception of their partner's hearing disability (Significant Other Assessment of Communication). Partners' level of hearing impairment, self-reported hearing disability (Self Assessment of Communication), use of hearing aids, and spouse satisfaction that their

    Objective To assess the safety, stability, and performance of the broad spectrum, light based Contact Hearing Device (CHD) on listeners with hearing impairment. Study Design Feasibility study. Setting Single-Site Research and Development Facility. Subjects Thirteen subjects with symmetric mild to severe sensorineural hearing impairment had the CHD placed bilaterally. Intervention A custom-molded light activated Tympanic Contact Actuator (TCA) was placed into each ear by a physician, where it stayed in contact with the umbo and a portion of the medial wall of the ear canal for four months. Each CHD was calibrated and programmed to provide appropriate broad-spectrum amplification. Main Outcome Measures Safety was determined through routine otologic examinations. Aided and pre-TCA-insertion unaided audiometric thresholds, Reception Threshold for Sentences (RTS), and Abbreviated Profile of Hearing Aid Benefit (APHAB) measurements were made to characterize system performance as well as the benefits of amplification via the CHD. Results The TCAs remained on subjects’ ears for an average total of 122 days, without causing signs of inflammation or infection, and there were no serious device-related adverse events. Measured average maximum output of 90–110 dB SPL in the 0.25–10 kHz range, average maximum gain before feedback of 40 dB, and functional gain through 10 kHz show extended bandwidth broad spectrum output and gain. RTS results showed significant aided improvements of up to 2.8 dB, and APHAB results showed clinically significant aided benefits in 11/12 (92%) subjects. Conclusion The safety, stability, and performance demonstrated in this initial 4-month study suggest that the CHD may offer a feasible way of providing broad-spectrum amplification appropriate to treat listeners with mild to severe hearing impairment.

    Diagnosis of child permanent hearing impairment (PHI) can be made with extreme timeliness compared to the past thanks to improvements in PHI identification through newborn hearing screening programmes. It now becomes essential to provide an effective amplification as quickly as possible in order to restore auditory function and favour speech and language development. The early fitting of hearing aids and possible later cochlear implantation indeed prompts the development of central auditory pathways, connections with secondary sensory brain areas, as well as with motor and articulatory cortex. The aim of this paper is to report the results of a strategic analysis that involves identification of strengths, weaknesses, opportunities and threats regarding the process of achieving early amplification in all cases of significant childhood PHI.

  14. Multisensory dysfunction accompanies crossmodal plasticity following adult hearing impairment.

    PubMed

    Meredith, M A; Keniston, L P; Allman, B L

    2012-07-12

    Until now, cortical crossmodal plasticity has largely been regarded as the effect of early and complete sensory loss. Recently, massive crossmodal cortical reorganization was demonstrated to result from profound hearing loss in adult ferrets (Allman et al., 2009a). Moderate adult hearing loss, on the other hand, induced not just crossmodal reorganization, but also merged new crossmodal inputs with residual auditory function to generate multisensory neurons. Because multisensory convergence can lead to dramatic levels of response integration when stimuli from more than one modality are present (and thereby potentially interfere with residual auditory processing), the present investigation sought to evaluate the multisensory properties of auditory cortical neurons in partially deafened adult ferrets. When compared with hearing controls, partially-deaf animals revealed elevated spontaneous levels and a dramatic increase (∼2 times) in the proportion of multisensory cortical neurons, but few of which showed multisensory integration. Moreover, a large proportion (68%) of neurons with somatosensory and/or visual inputs was vigorously active in core auditory cortex in the absence of auditory stimulation. Collectively, these results not only demonstrate multisensory dysfunction in core auditory cortical neurons from hearing impaired adults but also reveal a potential cortical substrate for maladaptive perceptual effects such as tinnitus.

    An evaluation of the installation and use of sound field systems in ten schools in England has been carried out. The evaluation included noise surveys of classrooms, questionnaire surveys of pupils and teachers and experimental testing of children with and without the use of SFS. The aim of this project was to investigate the impact of SFS on teaching and learning in elementary school classrooms, in particular, to ascertain whether the SFS differentially benefited children with hearing impairments. Barriers to teachers use of SFS were found in terms of equipment placement and maintenance, appropriate training, and teacher's knowledge. Nonetheless positive reports are recorded from both teachers and pupils. Teachers' and pupils' perceptions are compared with objective data evaluating change in performance when SFS are used for language and cognitive tasks. Data from children with hearing impairments and additional learning needs are analyzed for comparative purposes. The results are discussed in terms of effective practice for the use of SFS with elementary school pupils.

  16. An instructional guide for reducing the stress of hearing parents of hearing-impaired children.

    The impact of a self-instructional program to reduce stress levels of parents of hearing-impaired children is examined. Fifty parents with hearing-impaired children were randomly assigned to one of two groups: Participating Parents, who received a Self-Instructional Parent Program (SIPP); and Non-participating Parents, who received no such program. Findings indicate that the participating parents did not experience significant decreases in their stress levels or in the perceived incidence of misbehavior in their children in comparison with non-participating parents. Participating parents, however, reported a decrease in their children's misbehavior; non-participating parents noted an increase. Additionally, the findings also associated increasing stress on the part of parents with parental perceptions of burgeoning misbehavior on the part of the child.

    High frequency of hereditary pathologies resulting in congenital and prelingual auditory inefficiency necessitates organization of readily available medico-genetic counseling services based at specialized centres and an integrated dispensary system for the observation of families at risk of hereditary hearing impairment and identification of high-risk groups among the general population. Correct clinical diagnosis provides a basis for the strategy of molecular-genetic examination of a given patient and members of his (her) family. Results of the examination can be used for family planning and the choice of measures for the prevention of recurrent cases. The objective of the present work was to draw up the main lines of cooperative activities of deafness specialists and geneticists, propose indications for medico-genetic counseling, and distinguish groups at high risk of development of hereditary hearing impairment among the affected subjects and in the general population. It is shown that the efficiency of measures for the prevention of hereditary hearing loss is directly related to the availability of medico-genetic aid and the degree of involvement of risk groups in the examination.

    2013-12-01

    The authors address 3 questions: (a) What is evidence-based practice (EBP), and why is it important for adults with hearing impairment? (b) What is the evidence about intervention options for adults who fail a hearing screening and are identified with hearing impairment? (c) What intervention options do adults choose when identified with hearing impairment for the first time? The 5 steps of the EBP process are discussed in relation to a clinical question about whether hearing aids and communication programs reduce activity limitations and participation restrictions compared with no treatment for adults who fail a hearing screening and are identified with hearing impairment. Systematic reviews of the evidence indicate that both hearing aids and communication programs reduce activity limitations and participation restrictions for this population and are therefore appropriate options. A study is then described in which these options were presented to 153 clients identified with hearing impairment for the first time: 43% chose hearing aids, 18% chose communication programs, and the remaining 39% chose not to take any action. EBP supports the offer of intervention options to adults who fail a hearing screening and are identified with hearing impairment.

  2. Sentence intelligibility in noise for listeners with normal hearing and hearing impairment: influence of measurement procedure and masking parameters.

    PubMed

    2005-03-01

    Speech intelligibility measurements strongly depend on several procedural parameters. In order to obtain comparable results from different test procedures, these parameters must be investigated as to which should be standardized and which could be set freely. This study investigates the influence of noise level, noise type, and presentation mode on speech reception thresholds (SRTs), and intelligibility function slopes in noise for normal-hearing and hearing-impaired subjects. The noise presentation level had no significant influence on either SRTs or slope values, provided that the presentation level exceeded hearing threshold. Two stationary, speech-shaped noises produced identical results. Speech-simulating fluctuating noise yielded about 14 dB lower SRTs for normal-hearing subjects and about 10 dB lower SRTs for 20% of the heating-impaired subjects. Of the hearing-impaired subjects, 30% did not benefit from the modulations and showed similar SRTs as for stationary noise. Using continuous noise yielded lower SRTs compared to gated noise. However, the difference between the results in continuous and gated noise was not significant for the hearing-impaired subjects. A presentation level of 65 dB SPL (normal-hearing subjects) or 80 dB SPL (hearing-impaired subjects) and an interfering noise with a spectrum similar to the mean long-term average speech spectrum (LTASS) is suggested for comparable adaptive measurement procedures. A fluctuating, speech-shaped noise is recommended to differentiate between subjects.

    Although there are numerous single-channel noise reduction strategies to improve speech perception in noise, most of them improve speech quality but do not improve speech intelligibility, in circumstances where the noise and speech have similar frequency spectra. Current exceptions that may improve speech intelligibility are those that require a priori knowledge of the speech or noise statistics, which limits practical application. Hearing impaired (HI) listeners suffer more in speech intelligibility than normal hearing listeners (NH) in the same noisy environment, so developing better single-channel noise reduction algorithms for HI listeners is justified. Our model-based "sparse coding shrinkage" (SCS) algorithm extracts key speech information in noisy speech. We evaluate it by comparison with a state-of-the-art Wiener filtering approach using speech intelligibility tests with NH and HI listeners. The model-based SCS algorithm relies only on statistical signal information without prior information. Results show that the SCS algorithm improves speech intelligibility in stationary noise and is comparable to the Wiener filtering algorithm. Both algorithms improve intelligibility for HI listeners but not for NH listeners. Improvement is less in fluctuating (babble) noise than in stationary noise. Both noise reduction algorithms perform better at higher input signal-to-noise ratios (SNR) where HI listeners can benefit but where NH listeners have already reached ceiling performance. The difference between NH and HI subjects in intelligibility gain depends fundamentally on the input SNR rather than the hearing loss level. We conclude that HI listeners need different signal processing algorithms from NH subjects and that the SCS algorithm offers a promising alternative to Wiener filtering. Performance of all noise reduction algorithms is likely to vary according to extent of hearing loss and algorithms that show little benefit for listeners with moderate hearing loss may

    Hearing or visual impairments may negatively affect child's development and participation. Yet the literature about participation of children with hearing or visual impairments is insufficient. The present study aimed to compare participation patterns of children with visual impairments to those of children with hearing impairments and to typical peers and to examine the correlations between participation and socio-demographic parameters in each group. Participants were 70 children between the ages of 6-11: 25 with hearing impairments, 20 with visual impairments and 25 typical peers. All children filled the Children's Assessment of Participation and Enjoyment (CAPE). This self-report refers to participation in daily out of school activities. Children with hearing or visual impairments showed significant limited participation compared to typical peers, expressed in lower number of activities, lower participation intensity; more activities performed at home and with someone else. The limited participation was more emphasized among children with visual impairments. Socio-demographic variables (age, mother's education and socio-economic level) correlated with participation dimensions in both study groups. In conclusion, children with hearing or visual impairments may have restricted participation in out of school activities. Socio-demographic parameters may play a role in encouraging child's participation. Participation among these populations should be further studied in order to assist service providers to create intervention programs together with the child, for enhancing his/her inclusion in the community.

  9. Auditory Brainstem and Middle Latency Responses Measured Pre- and Posttreatment for Hyperacusic Hearing-Impaired Persons Successfully Treated to Improve Sound Tolerance and to Expand the Dynamic Range for Loudness: Case Evidence.

    PubMed

    2017-02-01

    In this report of three cases, we consider electrophysiologic measures from three hyperacusic hearing-impaired individuals who, prior to treatment to expand their dynamic ranges for loudness, were problematic hearing aid candidates because of their diminished sound tolerance and reduced dynamic ranges. Two of these individuals were treated with structured counseling combined with low-level broadband sound therapy from bilateral sound generators and the third case received structured counseling in combination with a short-acting placebo sound therapy. Each individual was highly responsive to his or her assigned treatment as revealed by expansion of the dynamic range by at least 20 dB at one or more frequencies posttreatment. Of specific interest in this report are their latency and amplitude measures taken from tone burst-evoked auditory brainstem response (ABR) and cortically derived middle latency response (MLR) recordings, measured as a function of increasing loudness at 500 and 2,000 Hz pre- and posttreatment. The resulting ABR and MLR latency and amplitude measures for each case are considered here in terms of pre- and posttreatment predictions. The respective pre- and posttreatment predictions anticipated larger pretreatment response amplitudes and shorter pretreatment response latencies relative to typical normal control values and smaller normative-like posttreatment response amplitudes and longer posttreatment response latencies relative to the corresponding pretreatment values for each individual. From these results and predictions, we conjecture about the neural origins of the hyperacusis conditions (i.e., brainstem versus cortical) and the neuronal sites responsive to treatment. The only consistent finding in support of the pre- and posttreatment predictions and, thus, the strongest index of hyperacusis and positive treatment-related effects was measured for MLR latency responses for wave Pa at 2,000 Hz.

Subjects with pure-tone thresholds greater than 20 dB in 0.5, 1.0 and 2.0 kHz were presented with a version of the W-22 list of phonetically balanced words under three conditions: (1) 'quiet', with the chamber noise below 28 dB and speech at 60 dB; (2) at a constant S/N ratio of +10 dB, and with a background white noise at 70 dB; and (3) same as condition (2), but with the background noise at 80 dB. The mean speech discrimination scores decreased significantly with noise in all groups. However, the decrease in binaural speech discrimination scores with an increase in hearing impairment was less for material presented under the noise conditions than for the material presented in quiet.

    2001-12-01

    This study was aimed at defining the relationship between noise-related hearing impairment in industrial workers exposed to continuous noise. For this malondialdehyde and glutathione peroxidase were analyzed as free radical form and antioxidant form. A total of 60 patients working in the units of a hydroelectric power plant were included in the study. This experimental group was further divided into three subgroups of 20 workers, each group exposed to a different noise level. The control group consisted of 20 male volunteers employed in the Medical Centre where the study was carried out. A standard ascending/descending method was applied to the subjects of the experimental and the control groups in order to determine their hearing thresholds at seven different frequencies between 250 and 8000 Hz. Then, 10 ml blood was collected from each person to measure the malondialdehyde values in plasma and glutathione peroxidase activity in erythrocytes. Slight sensorineural hearing impairment was found in group I beginning at 4 kHz and in group II beginning at 6 kHz. Statistically significant differences were observed in group I and II when compared to the control group (P<0.05). It was found that malondialdehyde levels increased in the experimental groups more than in the control groups. However, this increase was only significant in group I (P<0.05). Erythrocyte glutathione peroxidase activity significantly increased in group I and II compared to the other groups (P<0.05), also, the difference was significant between group I and II (P<0.05). Accordingly, it is suggested that free oxygen radicals may take a role in noise-related hearing impairment.

    We evaluated the possible effects of noise created by high energy shock waves on the hearing function of children treated with extracorporeal shock wave lithotripsy. A total of 65 children with normal hearing function were included in the study. Patients were divided into 3 groups, ie those becoming stone-free after 1 session of shock wave lithotripsy (group 1, 22 children), those requiring 3 sessions to achieve stone-free status (group 2, 21) and healthy children/controls (group 3, 22). Extracorporeal shock wave lithotripsy was applied with patients in the supine position with a 90-minute frequency and a total of 2,000 shock waves in each session (Compact Sigma, Dornier MedTech, Wessling, Germany). Second energy level was used with a maximum energy value of 58 joules per session in all patients. Hearing function and possible cochlear impairment were evaluated by transient evoked otoacoustic emissions test at 1.0, 1.4, 2.0, 2.8 and 4.0 kHz frequencies before the procedure, 2 hours later, and 1 month after completion of the first shock wave lithotripsy session in groups 1 and 2. In controls the same evaluation procedures were performed at the beginning of the study and 7 weeks later. Regarding transient evoked otoacoustic emissions data, in groups 1 and 2 there was no significant alteration in values obtained after shock wave lithotripsy compared to values obtained at the beginning of the study, similar to controls. A well planned shock wave lithotripsy procedure is a safe and effective treatment in children with urinary stones and causes no detectable harmful effect on hearing function.

  2. Sexual Behavior Among Persons With Cognitive Impairments.

    PubMed

    Thom, Robyn P; Grudzinskas, Albert J; Saleh, Fabian M

    2017-05-01

    Although the cognitively impaired are frequently included in heterogeneous studies of problematic sexual behavior, the epidemiology, etiology, and approach to assessment and treatment of persons with dementia and intellectual disability are distinct from those of the general population. The incidence of inappropriate sexual behavior among the intellectually disabled is 15-33%; however, the nature tends to be more socially inappropriate than with violative intent. Limited sociosexual education is a large contributor, and better addressing this area offers a target for prevention and treatment. A thorough clinical assessment of problematic sexual behaviors in the cognitively impaired requires understanding the patient's internal experience, which can be challenging. Assessment tools validated for the general population have not been validated for this population. Very few studies have assessed treatment approaches specifically among the cognitively impaired; however, research does suggest utility in habilitative, psychotherapeutic, and pharmacologic approaches which have been validated among the general population.

    Background. Previous research has found that hearing loss is associated with poorer cognitive function. The question is that when a hearing impairment is being compensated for by appropriately fitted monaural hearing aids, special precautions are still needed when screening cognitive function in older adults. Objective. This research examined cognitive function in elderly hearing aid users who used monaural hearing aids and whether the presence of a hearing impairment should be accounted for when screening cognitive function in these individuals. Methods. Auditory thresholds, sentence reception thresholds, and self-reported outcomes with hearing aids were measured in 34 older hearing aid users to ensure hearing aids were appropriately fitted. Mini-Mental State Examination (MMSE) results obtained in these participants were then compared to normative data obtained in a general older population exhibiting similar demographic characteristics. Stepwise multiple regression analyses were used to examine the effects of demographic and auditory variables on MMSE scores. Conclusions. Results showed that, even with appropriately fitted hearing aids, cognitive decline was significant. Besides the factors commonly measured in the literature, we believed that auditory deprivation was not being fully compensated for by hearing aids. Most importantly, screening of cognitive function should take into account the effects of hearing impairment, even when hearing devices have been appropriately fitted. PMID:25140321

    Objectives To (a) study the prevalence of hearing impairment in a cohort of very low birthweight (VLBW) infants and (b) evaluate the effectiveness of transient evoked otoacoustic emissions (TEOAE) as a first stage in‐hospital hearing screening tool in this population. Study design The study group was a cohort of 346 VLBW infants born in 1998–2000 at The Sheba Medical Center. The prevalence of hearing impairment in the study group was compared with that of all other newborn infants participating in a universal newborn hearing screening programme during the same period. To evaluate the effectiveness of TEOAE, a control group of 1205 healthy newborns who had no known risk factors for hearing impairment was selected. The results and follow up of hearing screening for these infants were examined retrospectively. Results Only one VLBW infant (0.3%) was diagnosed with bilateral sensory‐neural hearing loss. In addition, nine infants (2.7%) were diagnosed with conductive hearing loss. Bronchopulmonary dysplasia and low Apgar score were the most significant factors for predicting the occurrence of conductive hearing loss. The percentage of VLBW infants who successfully passed the in‐hospital TEOAE screening was 87.2, compared with 92.2% in the full term control group. No false negative cases were detected on follow up. Conclusions The study shows a low incidence of sensory‐neural hearing loss in a cohort of VLBW infants and a relatively high incidence of conductive hearing loss. TEOAE screening was found to be an effective first stage in‐hospital hearing screening tool in this population. PMID:16531449

    Children with hearing impairment commonly present with articulation deficits. This is considered one main characteristic. 24 pairs of children (5;00 - 6;11 yrs) with articulation deficits in the context of a language disorder were matched in the severity of the language disorder, age, gender and nonverbal intelligence. Of each matched pair one child had a hearing impairment, the other a specific language impairment. Both groups were compared for their articulation. In children with hearing impairment the influence of the severity of the hearing loss was evaluated. In both groups the same type of articulation deficit for consonants was found. Both groups of children had most frequently problems with sibilants. Children with specific language impairment had slightly more severe articulation deficits. In unvoiced plosives children with specific language impairment demonstrated more often substitutions. The severity of the language disorder, but not the severity of the articulation deficit, was correlated with the degree of hearing loss. Articulation deficits in children with hearing impairment are slightly less than in children with specific language impairment, but follow the same pattern.

    2001-09-01

    The limited number of studies concerning the prevalence of hearing loss and vision impairment and their causes, and the lack of strategies to prevent or treat the deleterious effects of hearing loss and vision impairment, point to a significant gap in the knowledge base concerning aged minority populations. This cross-sectional study evaluated the relationship between vision and hearing impairment and psychological well-being among a sample of 988 elderly African American persons. Fair or poor vision or hearing was reported for 36.5% and 26% of our sample, respectively. Reported prevalence rates for these impairments are considerably higher than rates previously documented in comparable studies of elderly people conducted in general (i.e., predominantly White) populations. Eighty-four percent of our study participants attempted to improve their vision through the use of eyeglasses. By contrast, only 4.3% of individuals in the study who described their hearing as poor reported using hearing aids. Using multivariate analysis and other related variables that have previously been identified as common predictors of psychological well-being, the findings of this study suggest that poor vision is independently associated with a lower level of psychological well-being among aged African Americans even after adjusting for sociodemographic characteristics, functional limitations, perceived health status, and cognition. Poor hearing was also found to be associated with a lower level of psychological well-being; however, this relationship was not independent but was mediated by the effect of hearing on functional status. These data indicate considerable potential for improved psychological well-being for African American elderly people through visual and audiological rehabilitation.

  10. Effects of signal level and spectral contrast on vowel formant discrimination for normal-hearing and hearing-impaired listeners.

    PubMed

    Woodall, Ashley; Liu, Chang

    2013-06-01

    The aim of this study was to determine whether increasing the overall speech level or the individual spectral contrasts of vowel sounds can improve vowel formant discrimination for listeners both with and without normal hearing. Thresholds of vowel formant discrimination were examined for the F2 frequencies of 3 American English vowels for listeners with and without normal hearing. Spectral contrasts of the F2 were enhanced by 3, 6, and 9 dB. Vowel stimuli were presented at 70 and 90 dB SPL. The thresholds of listeners with hearing impairment were reduced significantly after spectral enhancement was implemented, especially at 90 dB SPL, whereas normal-hearing listeners did not benefit from spectral enhancement. These results indicate that a combination of spectral enhancement of F2 and high speech level is most beneficial to improve vowel formant discrimination for listeners with hearing impairment.

    2010-09-01

    In tone languages such as Cantonese, a change in tone denotes a change in lexical meaning. The present study investigates the functional benefit of hearing devices in assisting tone perception among children with profound hearing impairment. Fifty-two children with profound hearing loss were categorized into two groups based on their primary type of hearing device - a hearing aid group and cochlear implant group. A 75-item tone identification test covering all 15 Cantonese tone contrast pairs was administered to each subject under two conditions - unaided (hearing devices turned off) and aided (devices turned on). The proportion of correct responses was computed as the total score for all items and subtotal contrast scores for each of the 15 tone contrasts. The results indicated no significant differences between the children wearing hearing aids and those with cochlear implants under the unaided or the aided condition (z = -0.91, p = 0.36; z = -0.40, p = 0.69, respectively). Regardless of the type of device used, the total scores under the aided condition were higher than those under the unaided condition (z = -3.55 for the hearing aid group; z = -4.87 for the cochlear implant group, both ps < 0.01). Children wearing hearing devices generally have a satisfactory functional gain in tone perception. No major observable difference was noted between children using cochlear implants and those using hearing aids. Tone contrast pairs with dissimilar fundamental frequency at onset and dissimilar tone contour patterns were more easily identified.

  12. Within-consonant perceptual differences in the hearing impaired ear

    Trevino, Andrea; Allen, Jont B.

    2013-01-01

    The consonant recognition of 17 ears with sensorineural hearing loss is evaluated for 14 consonants /p, t, k, f, s, ʃ , b, d, g, v, z, ʒ, m, n/+/ɑ/, under four speech-weighted noise conditions (0, 6, 12 dB SNR, quiet). One male and one female talker were chosen for each consonant, resulting in 28 total consonant-vowel test tokens. For a given consonant, tokens by different talkers were observed to systematically differ, in both the robustness to noise and/or the resulting confusion groups. Such within-consonant token differences were observed for over 60% of the tested consonants and all HI ears. Only when HI responses are examined on an individual token basis does one find that the error may be limited to a small subset of tokens with confusion groups that are restricted to fewer than three confusions on average. Averaging different tokens of the same consonant can raise the entropy of a listener's responses (i.e., the size of the confusion group), causing the listener to appear to behave in a less systematic way. Quantifying these token differences provides insight into HI perception of speech under noisy conditions and characterizes each listener's hearing impairment. PMID:23862835

    1986-03-01

    The Vowel Corrector is a visual aid to be used in speech training of the hearing impaired. The display provides information about the identity of vowels spoken in isolation or in monosyllables. Vowels appear on a screen as differently located areas in a space, the coordinates of which are obtained from a dimensional analysis of vowel spectra. Resolving properties of the device, indexed by a measure of area overlap, are examined in detail. In particular, implications for differentiating utterances of male, female, and child speakers are studied. Results show that the device has promising features and is especially useful for exploring the vowel space as well as for learning a global differentiation of the vowels. The discrimination of spectrally similar vowels is limited, however. Ideas for future improvements are discussed.

    The number of deaf children has dramatically increased in the past few decades. These children present to the pediatric dentist a unique set of challenges mostly pertaining to the establishment of communication with them. There have been very few attempts in the past to break down these challenges and formulate a strategy on how to manage them effectively. This is a case report of a child who was successfully managed using two different modes of communication. Finally, the advantages and disadvantages are mentioned, and a common strategy incorporating the positives of both the methods has been devised.

    Hearing-impaired patients often encounter obstacles in communication. Not all of them wear hearing aids, citing issues with usage difficulty and discomfort in wearing. To overcome these difficulties, a new endeavor was started to improve sound intelligibility from the speaker's side. The present study objectively evaluated an intelligible-hearing (IH) loudspeaker by means of magnetoencephalography. Magnetic counterparts of mismatch negativity (MMNm) to pronunciation ('mi' and 'ni') were recorded and compared when they were transmitted from the IH loudspeaker and from a normal-hearing loudspeaker. On using the IH loudspeaker, the peak latency was found to be significantly shortened. In the case of hearing-impaired participants, marked MMNm responses were observed only when the IH loudspeaker was used. These findings suggest that improving sound intelligibility may be a supportive and rehabilitative approach for hearing-impaired patients.

  17. Decision strategies of hearing-impaired listeners in spectral shape discrimination

    Lentz, Jennifer J.; Leek, Marjorie R.

    2002-03-01

    The ability to discriminate between sounds with different spectral shapes was evaluated for normal-hearing and hearing-impaired listeners. Listeners detected a 920-Hz tone added in phase to a single component of a standard consisting of the sum of five tones spaced equally on a logarithmic frequency scale ranging from 200 to 4200 Hz. An overall level randomization of 10 dB was either present or absent. In one subset of conditions, the no-perturbation conditions, the standard stimulus was the sum of equal-amplitude tones. In the perturbation conditions, the amplitudes of the components within a stimulus were randomly altered on every presentation. For both perturbation and no-perturbation conditions, thresholds for the detection of the 920-Hz tone were measured to compare sensitivity to changes in spectral shape between normal-hearing and hearing-impaired listeners. To assess whether hearing-impaired listeners relied on different regions of the spectrum to discriminate between sounds, spectral weights were estimated from the perturbed standards by correlating the listener's responses with the level differences per component across two intervals of a two-alternative forced-choice task. Results showed that hearing-impaired and normal-hearing listeners had similar sensitivity to changes in spectral shape. On average, across-frequency correlation functions also were similar for both groups of listeners, suggesting that as long as all components are audible and well separated in frequency, hearing-impaired listeners can use information across frequency as well as normal-hearing listeners. Analysis of the individual data revealed, however, that normal-hearing listeners may be better able to adopt optimal weighting schemes. This conclusion is only tentative, as differences in internal noise may need to be considered to interpret the results obtained from weighting studies between normal-hearing and hearing-impaired listeners.

    Hearing loss is common in school-age individuals with Williams syndrome (WS) and extensive in adults. Prior studies with relatively small sample sizes suggest that hearing loss in WS has an early onset and may be progressive, yet the auditory phenotype and the scope of the hearing loss have not been adequately characterized. We used standard audiometric tools: Otoscopy, tympanometry, air-conduction (bone conduction when available) behavioral testing, and distortion product otoacoustic emissions (DPOAEs) to measure hearing sensitivity and outer hair cell function. We tested 81 individuals with WS aged 5.33 to 59.50 years. 63% of the school-age and 92% of the adult participants had mild to moderately-severe hearing loss. The hearing loss in at least 50% was sensorineural. DPOAE testing corroborated behavioral results. Strikingly, 12 of 14 participants with hearing within normal limits bilaterally had 4000-Hz DPOAE input/output (DPOAE IO) functions indicative of outer hair cell damage and impaired cochlear compression. Our results indicate that hearing loss is very common in WS. Furthermore, individuals with WS who have “normal” hearing as defined by behavioral thresholds may actually have sub-clinical impairments or undetected cochlear pathology. Our findings suggest outer hair cell dysfunction in otherwise normal hearing individuals. The DPOAE IO in this same group revealed growth functions typically seen in groups with noise-induced damage. Given this pattern of findings, individuals with WS may be at increased risk of noise-induced hearing loss. Recommendations regarding audiological testing for individuals with WS and accommodations for these individuals in both academic and nonacademic settings are provided. PMID:20425785

    2012-01-01

    Client involvement in health decision making, or shared decision making, is increasingly being advocated. For example, rehabilitation interventions such as hearing aids and communication programs can be presented as options to adults with hearing impairment seeking help for the first time. Our previous research focused on the predictors of intervention decisions when options were presented with a decision aid. However, not all participants took up the intervention they initially decided upon. Although it is interesting to understand what informs adults with hearing impairment's intervention decisions, it is their intervention uptake and outcomes which best represent the ultimate end result of the rehabilitation process. This prospective study investigated the predictors of uptake and of successful outcomes of hearing aids and communication programs in middle-aged and older adults with hearing impairment seeking help for the first time. Using shared decision making, 153 participants with hearing impairment (average of air conduction thresholds at 0.5, 1, 2, and 4 kHz greater than 25 dB HL in at least one ear) aged 50 yr and older were presented with intervention options: hearing aids, communication programs (group or individual), and no intervention. Each participant received a decision aid and had at least 1 wk to consider intervention options before the intervention decision was made. Outcome measures for both hearing aids and communication programs at 3 mo after intervention completion were benefit (measured with the Client-Oriented Scale of Improvement), composite outcomes (measured with the International Outcome Inventory), and reduction in self-reported hearing disability (measured with the Hearing Handicap Questionnaire). Multivariate analysis (logistic and linear regression) identified predictors of intervention uptake and of successful outcomes when all other variables were held constant. Almost a quarter of the 153 participants (24%) did not take up the

    Our purpose was to determine the extent to which a predetermined set of modifiable impairments predicted progression of disability. We conducted a 3-year follow-up of two community-based cohorts of older adults. The impairment areas included lower extremity, upper extremity, hearing, vision, and affect. Home management and social or productive activities were the domains of function investigated. All five impairments were of at least borderline significance in predicting decline in both functional domains in both cohorts with the exception of hearing for home management activities. The five impairments together explained from 17% to 23% of the decline seen in the functional outcomes (partial R(2)s 0.17 to 0.23). Five prevalent and potentially modifiable impairments explained much of the progressive disability experienced. Given the priority that older patients place on function as a health outcome, these impairments should be routinely assessed and modified.

    To identify and quantify sources of variability in scores on the speech, spatial, and qualities of hearing scale (SSQ) and its short forms among normal-hearing and hearing-impaired subjects using a French-language version of the SSQ. Multi-regression analyses of SSQ scores were performed using age, gender, years of education, hearing loss, and hearing-loss asymmetry as predictors. Similar analyses were performed for each subscale (Speech, Spatial, and Qualities), for several SSQ short forms, and for differences in subscale scores. One hundred normal-hearing subjects (NHS) and 230 hearing-impaired subjects (HIS). Hearing loss in the better ear and hearing-loss asymmetry were the two main predictors of scores on the overall SSQ, the three main subscales, and the SSQ short forms. The greatest difference between the NHS and HIS was observed for the Speech subscale, and the NHS showed scores well below the maximum of 10. An age effect was observed mostly on the Speech subscale items, and the number of years of education had a significant influence on several Spatial and Qualities subscale items. Strong similarities between SSQ scores obtained across different populations and languages, and between SSQ and short forms, underline their potential international use.

    Genetic testing for hereditary hearing impairment has become more routinely available as a diagnostic tool in the outpatient clinic. However, little is known about the psychological impact of a genetic diagnosis. To evaluate this impact, an exploratory study was conducted. Prospectively, 48 individuals who underwent genetic testing for hereditary hearing impairment were included in this study. Study participants were asked to fill out the following questionnaires: Hospital Anxiety Depression Scale, Impact of Event Scale, Self-Efficacy 24, Illness Cognition Questionnaire and the Inventory for Social Reliance. Questionnaires were filled out on three occasions: before genetic testing, directly after counselling on either positive or negative test results, and six weeks thereafter. No significant differences were found between the group that received a genetic diagnosis for their hearing impairment and the group that did not. This study did not demonstrate differences between receiving a genetic diagnosis or not; however, special attention to psychological well-being should be offered to hearing-impaired patients who seek a genetic diagnosis for their hearing impairment. Additionally, the psychological impact of sensorineural hearing impairment might be greater than the impact of a genetic diagnosis itself. Based on the current exploratory study, there are no psychological reasons in favour of or against genetic testing for hereditary hearing impairment. © 2017 John Wiley & Sons Ltd.

    The objective of this study is to explore the sensitivity to intermodal asynchrony in audiovisual speech with moderate to severe sensorineural hearing loss. Based on previous studies, two opposing expectations were an increase in sensitivity, as hearing-impaired listeners heavily rely on lipreading in daily life, and a reduction in sensitivity, as hearing-impaired listeners tend to be elderly and advanced age could potentially impair audiovisual integration. Adults with normal (N = 11, ages between 23 and 50 yrs) and impaired hearing (N = 11, ages between 54 and 81 yrs, the pure-tone average between 42 and 67 dB HL) participated in two experiments. In the first experiment, the synchrony judgments were recorded for varying intermodal time differences in audiovisual sentence recordings. In the second experiment, the intelligibility of audiovisual and audio-only speech was measured in speech-shaped noise, and correlations were explored between the synchrony window and intelligibility scores for individual listeners. Similar to previous studies, a sensitivity window on the order of a few hundred milliseconds was observed with all listeners. The average window shapes did not differ between normal-hearing and hearing-impaired groups; however, there was large individual variability. Individual windows were quantified by Gaussian curve fitting. Point of subjective simultaneity, a measure of window peak shift from the actual synchrony point, and full-width at half-maximum, a measure of window duration, were not correlated with participant's age or the degree of hearing loss. Points of subjective simultaneity were also not correlated with speech intelligibility scores. A moderate negative correlation that was significant at most conditions was observed between the full-width at half-maximum values and intelligibility scores. Contrary to either expectation per se, there was no indication of an effect of hearing impairment or age on the sensitivity to intermodal asynchrony in

    In India, owing to cultural norms and a lack of formal long-term care facilities, responsibility for care of the older person falls primarily on the family. Based on the stress process model, we assessed the association of type and number of impairments of older persons (∼primary stressors) with caregiver burden among their family caregivers in rural South India. All impaired older persons (aged ≥60, with impairment in activities of daily living (ADL) or cognition or vision or hearing) residing in 8 villages in Bangalore district, Karnataka, India, and their primary informal caregivers were interviewed. Caregiver burden was measured using the Zarit Burden Interview (ZBI; higher score indicating greater perceived burden). Linear regression models, adjusting for background characteristics of older persons and caregivers, assessed the association of type of impairment (physical [Yes/No], cognitive [Yes/No], vision [Yes/No] and hearing [Yes/No]) and number (1 or 2 or 3 or 4) of older person impairments with caregiver burden. A total of 140 caregivers, caring for 149 older persons, were interviewed. The mean (standard deviation) ZBI score was 21.2 (12.9). Of the various older person impairments, ZBI score was associated only with physical impairment (β=6.6; 95% CI: 2.1-11.1). Relative to caregivers of older person with one impairment, those caring for an older person with all 4 impairments had significantly higher ZBI score (β=13.9; CI: 2.5-25.4). Caregivers of older persons with multiple impairments, especially physical impairment, are vulnerable. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  8. The effect of spatial separation on informational masking of speech in normal-hearing and hearing-impaired listeners

    Arbogast, Tanya L.; Mason, Christine R.; Kidd, Gerald

    2005-04-01

    The ability to understand speech in a multi-source environment containing informational masking may depend on the perceptual arrangement of signal and masker objects in space. In normal-hearing listeners, Arbogast et al. [J. Acoust. Soc. Am. 112, 2086-2098 (2002)] found an 18-dB spatial release from a primarily informational masker, compared to 7 dB for a primarily energetic masker. This article extends the earlier work to include the study of listeners with sensorineural hearing loss. Listeners performed closed-set speech recognition in two spatial conditions: 0° and 90° separation between signal and masker. Three maskers were tested: (1) the different-band sentence masker was designed to be primarily informational; (2) the different-band noise masker was a control for the different-band sentence; and (3) the same-band noise masker was designed to be primarily energetic. The spatial release from the different-band sentence was larger than for the other maskers, but was smaller (10 dB) for the hearing-impaired group than for the normal-hearing group (15 dB). The smaller benefit for the hearing-impaired listeners can be partially explained by masker sensation level. However, the results suggest that hearing-impaired listeners can use the perceptual effect of spatial separation to improve speech recognition in the presence of a primarily informational masker. .

  9. Phoneme recognition in modulated maskers by normal-hearing and aided hearing-impaired listeners.

    Phatak, Sandeep A; Grant, Ken W

    2012-09-01

    This study measured the influence of masker fluctuations on phoneme recognition. The first part of the study compared the benefit of masker modulations for consonant and vowel recognition in normal-hearing (NH) listeners. Recognition scores were measured in steady-state and sinusoidally amplitude-modulated noise maskers (100% modulation depth) at several modulation rates and signal-to-noise ratios. Masker modulation rates were 4, 8, 16, and 32 Hz for the consonant recognition task and 2, 4, 12, and 32 Hz for the vowel recognition task. Vowel recognition scores showed more modulation benefit and a more pronounced effect of masker modulation rate than consonant scores. The modulation benefit for word recognition from other studies was found to be more similar to the benefit for vowel recognition than that for consonant recognition. The second part of the study measured the effect of modulation rate on the benefit of masker modulations for vowel recognition in aided hearing-impaired (HI) listeners. HI listeners achieved as much modulation benefit as NH listeners for slower masker modulation rates (2, 4, and 12 Hz), but showed a reduced benefit for the fast masker modulation rate of 32 Hz.

    2014-08-01

    This study compared modulation benefit for phoneme recognition obtained by normal-hearing (NH) and aided hearing-impaired (HI) listeners. Consonant and vowel recognition scores were measured using nonsense syllables in the presence of a steady-state noise and four vocoded speech maskers. Vocoded maskers were generated by modulating the steady-state noise, in either one or six frequency channels, with the speech envelope extracted from the speech of either a single talker or a four-talker babble. Aided HI listeners obtained lower consonant recognition scores than NH listeners in all masker conditions. Vowel recognition scores for aided HI listeners were comparable to NH scores, except in the six-channel vocoded masker conditions where they were relatively lower. Analysis using the extended speech intelligibility index developed by Rhebergen, Versfeld, and Dreschler [(2006). J. Acoust. Soc. Am. 120(6), 3988-3997] suggested that the signal-to-noise ratio deficit observed in aided HI listeners was largely due to uncompensated audibility loss. There was no significant difference between modulation masking release obtained by NH and aided HI listeners for both consonant and vowel recognition.

    Spectral peak resolution was investigated in normal hearing (NH), hearing impaired (HI), and cochlear implant (CI) listeners. The task involved discriminating between two rippled noise stimuli in which the frequency positions of the log-spaced peaks and valleys were interchanged. The ripple spacing was varied adaptively from 0.13 to 11.31 ripples/octave, and the minimum ripple spacing at which a reversal in peak and trough positions could be detected was determined as the spectral peak resolution threshold for each listener. Spectral peak resolution was best, on average, in NH listeners, poorest in CI listeners, and intermediate for HI listeners. There was a significant relationship between spectral peak resolution and both vowel and consonant recognition in quiet across the three listener groups. The results indicate that the degree of spectral peak resolution required for accurate vowel and consonant recognition in quiet backgrounds is around 4 ripples/octave, and that spectral peak resolution poorer than around 1-2 ripples/octave may result in highly degraded speech recognition. These results suggest that efforts to improve spectral peak resolution for HI and CI users may lead to improved speech recognition.

    The purpose of this study was to compare vowel productions by deaf cochlear implant (CI) children, hearing-impaired hearing aid (HA) children and normal-hearing (NH) children. 73 children [mean age: 9;14 years (years;months)] participated: 40 deaf CI children, 34 moderately to profoundly hearing-impaired HA children and 42 NH children. For the 3 corner vowels [a], [i] and [u], F(1), F(2) and the intrasubject SD were measured using the Praat software. Spectral separation between these vowel formants and vowel space were calculated. The significant effects in the CI group all pertain to a higher intrasubject variability in formant values, whereas the significant effects in the HA group all pertain to lower formant values. Both hearing-impaired subgroups showed a tendency toward greater intervowel distances and vowel space. Several subtle deviations in the vowel production of deaf CI children and hearing-impaired HA children could be established, using a well-defined acoustic analysis. CI children as well as HA children in this study tended to overarticulate, which hypothetically can be explained by a lack of auditory feedback and an attempt to compensate it by proprioceptive feedback during articulatory maneuvers.

    This study set out to obtain information on the impact of trainable hearing aids among clinicians and hearing aid users and candidates. Two online adaptive surveys were developed to evaluate provision, uptake and experience or expectation of trainable hearing aids. Responses from 259 clinicians, 81 hearing aid users and 23 candidates for hearing aids were included. Over half of the clinicians surveyed activated trainable features in hearing aids. Most of these clinicians activated trainable features for selected users and reported positive findings. Most commonly trainable features were not activated because the hearing aid controls had already been disabled for management or client preference. One-third reported that they had no access to trainable aids or they were unsure about the presence or activation of trainable features. The remaining clinicians never activated trainable features. One in five users reported having used trainable aids and 93% would train again. Over 85% of the remaining hearing-impaired adults were interested in trainable aids. Positive reports from most providers and users who had experience with the trainable feature support the provision of trainable aids to selected clients, pending more evidence-based data to support the clinical management of such devices.

    This cohort study of persons aged 65 years and over, conducted in the Yoruba-speaking regions of Nigeria determines the prevalence and correlates of hearing impairment (HI) in the elderly population. Self-reports of HI and its putative risk factors among several indices were obtained using face-to-face interviews. HI was based on self-report, complemented by observer’s evaluation. HI was found in 79, giving a prevalence of 6.1%. Gender difference was not significant but increasing age was associated with higher prevalence. Logistic regression analysis that adjusted for age and sex, revealed that history of recurrent suppurative otitis media (OR=4.6, CI=2.3-8.9, P=0.01) and head injury (OR=2.2, CI=1.1-4.3, P=0.02) and current hypertension (OR=2.1, CI=1.2-3.6, P=0.01) were significantly associated with HI. No identifiable risk factors were found in 32 (40.5%) of the respondents. We conclude that the prevalence of HI among the elderly in Nigeria is comparable to reports from other countries. Identified risk factors were preventable or controllable. The large proportion of elderly with no identifiable risk factors, presumably presbyacusis, suggests a need for further study. The strategies for control of these risk factors and hearing aid support should be integrated into health care policy initiative for elderly persons in the sub-Saharan Africa. PMID:20307358

    Observational studies suggested an association between hearing impairment and cognitive disorders. However, whether hearing impairment is an independent risk factor or a harbinger of Alzheimer's disease remains controversial. Our goal was to assess the association between hearing impairment (HI) and the risk of Alzheimer's disease (AD) by conducting a meta-analysis of prospective cohort studies. We comprehensively searched the PubMed, Embase, Web of Science and Cochrane Library databases on January 19, 2016 to incorporate all the prospective cohort studies meeting the inclusion criteria to perform a systematic review and meta-analysis. Four prospective cohort studies with comparison between hearing impairment and normal hearing were incorporated, with 7461 participants. The outcomes of three studies were the incidence of Alzheimer's disease and the outcome of the fourth study was the incidence of mild cognitive impairment. The overall combined relative risk of people with hearing impairment to develop Alzheimer's disease was 4.87 (95% CI 0.90-26.35; p = 0.066), compared with the control group. Since both Alzheimer's disease and mild cognitive impairment are cognitive disorders, we incorporated all the four studies and the overall combined relative risk was 2.82 (95% CI 1.47-5.42; p = 0.002), indicating that the difference was significant. This meta-analysis suggests that hearing impairment significantly increases the risk of cognitive disorders and future well-designed prospective cohort studies are awaited to confirm the association between hearing impairment and risk of Alzheimer's disease.

  18. Students with hearing impairment at a South African university: Self-identity and disclosure.

    2016-01-01

    A growing number of students with hearing loss are being granted access to higher education in South Africa due to the adoption of inclusive educational policies. However, available statistics indicate that participation by students with hearing impairments in higher education remains low and research suggests that support provisioning for those who do gain access is inadequate. This article aims to illustrate that the assumed self-identity of students with hearing impairment influences their choice to disclose their disability. The choice not to disclose their hearing loss prevents them from accessing the necessary reasonable accommodations and this in turn may affect their eventual educational success. Reported here is a qualitative descriptive case study at a South African university. Purposive sampling methods were employed. Data were gathered from in-depth interviews with seven students with hearing impairment ranging from moderate to profound, using spoken language. Constructivist grounded theory was used as an approach to the process of generating and transforming the data, as well as the construction of theory. All the student participants identified as having a hearing rather than a D/deaf identity cultural paradigm and viewed themselves as 'normal'. Linked to this was their unwillingness to disclose their hearing impairment and thus access support. It is crucially important for academic, support and administrative staff to be aware of both the assumed 'hearing' identity and therefore subsequent non-disclosure practices of students with a hearing impairment using the oral method of communication. Universities need to put measures in place to encourage students to voluntarily disclose their hearing impairment in order to provide more targeted teaching and learning support. This could lead to improved educational outcomes for students.

    Hearing-impaired children who are identified early and appropriately managed have improved outcomes in speech, language, cognitive and social development. Enhanced parental awareness of their child's hearing disability, behavioral, developmental and psychosocial limitations is essential to sustaining timely detection and appropriate intervention. Additionally, availability of services for diagnosis, treatment and habilitation would improve the demand for pedaudiological care in this community. To describe level of parental awareness of childhood HI and the pattern of access to and utilization of ambulatory care services. Thirty-three parents of lower primary school-going children who failed audiometric screening from sampled schools in Kisumu district, western Kenya. First person to detect HI, age of child at first suspicion of HI, source of ambulatory health care and use of the health care facilities. The prevalence of HI was 2.48%. Most parents/guardians (69.7%) were aware of their child's hearing impairment. Of these, 63.6% were first to detect HI in the pupils, while 30.3% were detected by screen. Most children (57.2%) were first recognized with (HI) after age 2 years. The mean age at identification was 5.5 years. The median travel distance to the preferred health care facility was 2 km (IQR 1-2.5). Parents seldom sought or lacked help for their hearing-impaired children. Of 27.3% who asked for hearing assessment, 9.1% received some counsel on HI and 12.1% received medication, one (3%) was referred for audiological assessment and none used a hearing aid. Use of health facilities for maternal care was (65.7%) and immunization (62.9%). Despite adequate parental awareness of chronic childhood disability, health facilities were underutilized. This indicates the need to further stimulate and maintain a desirable level of uptake of services for diagnosis, treatment and habilitation of childhood HI, while sustaining delivery of effective and acceptable high quality

    Hearing loss is the third most common chronic physical condition in the United States, and is more prevalent than diabetes or cancer (1). Occupational hearing loss, primarily caused by high noise exposure, is the most common U.S. work-related illness (2). Approximately 22 million U.S. workers are exposed to hazardous occupational noise (3). CDC compared the prevalence of hearing impairment within nine U.S. industry sectors using 1,413,789 noise-exposed worker audiograms from CDC's National Institute for Occupational Safety and Health (NIOSH) Occupational Hearing Loss Surveillance Project (4). CDC estimated the prevalence at six hearing impairment levels, measured in the better ear, and the impact on quality of life expressed as annual disability-adjusted life years (DALYs), as defined by the 2013 Global Burden of Disease (GBD) Study (5). The mining sector had the highest prevalence of workers with any hearing impairment, and with moderate or worse impairment, followed by the construction and manufacturing sectors. Hearing loss prevention, and early detection and intervention to avoid additional hearing loss, are critical to preserve worker quality of life.

    2011-06-01

    Inherited hearing impairment is a frequent and highly heterogeneous condition. Among the different subtypes of autosomal recessive non-syndromic hearing impairment, DFNB1 is remarkable for its high frequency in most populations. It is caused by mutations in the coding region or splice-sites of the GJB2 gene, or by mutations affecting regulatory sequences that are essential for the expression of this gene. GJB2 encodes connexin-26, a protein component of intercellular gap junctions, which play crucial physiological roles in the cochlea. Because of its high frequency, DFNB1 hearing impairment has received continued attention from researchers along the years, resulting in a wealth of data that is unparalleled among these disorders. Here we review our current knowledge on the genetic, molecular, and phenotypic aspects of this subtype of hearing impairment.

    In a population-based sample, we determined whether a larger proportion of essential tremor (ET) cases reported hearing impairment compared with controls. Ninety-six (38.7%) of 248 ET cases versus 1,371 (29.4%) of 4,669 controls (p = 0.002) reported hearing impairment. In a logistic regression analysis adjusted for age, gender, educational level, depressive symptoms, and dementia, participants who reported hearing impairment were 30% more likely to suffer from ET than were controls (odds ratio 1.3; 95% confidence interval 1.01–1.7; p = 0.04). ET seemed to be associated with reported hearing impairment. The basis for this finding, which has been noted in several studies, deserves further exploration. PMID:18073494

    Hypernasality is considered a prevalent speech abnormality that could significantly contribute to the unintelligibility of the hearing-impaired speakers. The aim of this study was to evaluate the effect of cochlear implantation and the duration of hearing loss on nasalance of speech of a postlingually impaired group of Saudi adult patients. Retrospective study. This study included 25 postlingually hearing-impaired patients who underwent cochlear implantation and 25 age-matched control subjects. Patients were divided into three groups according to the duration of hearing loss. The nasometric data of the hearing-impaired group were compared with the control group. Also, the preoperative values were compared with the postoperative values 6, 12, and 24 months after surgery. Significant differences were demonstrated between the preimplantation nasalance scores of the three subgroups and between the patients and control groups. There were statistically significant differences demonstrated between the pre- and the postimplantation nasalance values for the three groups of patients. Cochlear implantation appears to have significant effects on improving the nasalance of the speech of postlingually hearing-impaired adult patients. However, the degree of improvement might vary according to the duration of hearing loss the patients had preimplantation. Copyright © 2012 The Voice Foundation. Published by Mosby, Inc.

  1. Sunrise alarm clock for the hearing impaired - biomed 2011.

    PubMed

    Follum, James D; Catchpole, Jennifer M

    2011-01-01

    The Sunrise Alarm Clock is a device designed to be more effective than standard alarm clocks and more pleasant than specialty devices in waking the hearing impaired. This is accomplished with the inclusion of visual, physical, and audio alarms. The visual alarm stimulus is created by manipulating the light output of a bedside lamp to mimic the sunrise. This is achieved by varying the duty cycle of a pulse width modulated signal supplied through a standard three-prong receptacle located on the side of the alarm clock. Physical alarms are in the form of wristbands containing vibrating motors. Finally, audio alarms are provided with both volume and pitch control to match the user’s specific needs. The entire system is designed with two users in mind by providing two independently controlled receptacles, wristbands, and audio systems. At the conclusion of development, a nearly fully functional prototype has been produced. The prototype’s audio and physical alarm system along with one visual alarm are fully functional. Shortcomings include poor timekeeping accuracy and problems clearly displaying the time. Even so, this development in sleep technology is capable of performing its task and waking its user with all three alarm systems.

  3. Masker phase effects in normal-hearing and hearing-impaired listeners: Evidence for peripheral compression at low signal frequencies

    NASA Astrophysics Data System (ADS)

    Oxenham, Andrew J.; Dau, Torsten

    2004-10-01

    The presence of cochlear-based compression at low frequencies was investigated by measuring phase effects in harmonic maskers. In normal-hearing listeners, the amount of masking produced depends strongly on the phase relationships between the individual masker components. This effect is thought to be determined primarily by properties of the cochlea, including the phase dispersion and compressive input-output function of the basilar membrane. Thresholds for signals of 250 and 1000 Hz were measured in harmonic maskers with fundamental frequencies of 12.5 and 100 Hz as a function of the masker phase curvature. Results from 12 listeners with sensorineural hearing loss showed reduced masker phase effects, when compared with data from normal-hearing listeners, at both 250- and 1000-Hz signal frequencies. The effects of hearing impairment on phase-related masking differences were not well simulated in normal-hearing listeners by an additive white noise, suggesting that the effects of hearing impairment are not simply due to reduced sensation level. Maximum differences in masked threshold were correlated with auditory filter bandwidths at the respective frequencies, suggesting that both measures are affected by a common underlying mechanism, presumably related to cochlear outer hair cell function. The results also suggest that normal peripheral compression remains strong even at 250 Hz. .

    Among all of the sources responsible for noise pollution, traffic related sources are of great environmental concern and increasing level of discomfort in urban areas with increasing traffic concentration. It will be a larger and serious problem in the future, if effective precautions are not taken addressed and attended to. Hence, a study was undertaken to measure the levels of road traffic noise at major intersections of Surat city, located in Western India and assess the hearing impairment among the exposed group of population i.e. the traffic policemen. Manual noise measurements and vehicle counts were performed at three of the busiest traffic intersections in the city for a period of 12 h. Audiometric screening was done on 46 policemen working at these intersections to determine the occurrence of hearing impairment. At all the three intersections, Leq measured was well above the permissible levels of 65 dBA for daytime. The Lmax recorded for three intersections were 84.6 dBA (07:36 pm), 87.3 dBA (06:32 pm) and 85.6 dBA (11:41 am). Audiometric screening showed that only 10 policemen (22%) had normal hearing. Slight, moderate and severe hearing impairment was recorded among 13 (28%), 18 (39%) and 5 (11%) policemen respectively. Of the total 46 policemen, none had profound impairment (deafness, hearing loss >81 dB). Of the 36 policemen having hearing impairment, 27 had bilateral impairment.

    Although we've made big strides in perinatal and neonatal care, auditory handicap remains a serious complication in those who were born very premature. The aim was to determine the prevalence and analyze possible risk factors of hearing impairment in very-low-birth-weight (VLBW) infants. This was a retrospective study by reviewing medical records of all VLBW infants (BW ≤ 1500 g) admitted to NICU of Chang Gung Children's Hospital over 2 years period from Jan. 2010 to 2011. Brainstem auditory evoked potentials (BAEP) hearing screening was performed at 3 months postnatal corrective age and repeated if failed the 1st time, then refer to ENT doctor if BAEP confirmed abnormal. All VLBW infants examined for hearing impairment were included and data were retrieved retrospectively and analyzed for neonatal risk factors using logistic regression. Over the period, 309 VLBW infants were screened. Prevalence of uni- or bilateral hearing impairment was 3.9% (12/309; 95% CI 2.6-4.1). The mean corrective age on diagnosed of hearing impairment was 2.9 ± 1.1 (range 1-5) months. Mean gestational age was 27.9 weeks (SD 1.4) and mean birth weight was 1028 g (SD 180). By univariant analysis for hearing impairment, severe birth asphyxia, craniofacial anomalies, ventilator dependence, patent ductus arteriosus ligation, and use of postnatal ototoxins yielded good prediction of hearing impairment in this population. However, using multivariate analysis revealed that the only independent risk factors for hearing impairment were ototoxins (OR: 3.62; CI: 1.67-7.82), PDA ligation (OR: 4.96; CI: 2.34-10.52), craniofacial anomalies (OR: 3.42; CI: 1.70-6.88)and assisted prolonged use of oxygen at gestational age of >36 weeks (OR: 5.94; CI: 2.61-13.54). The incidence of hearing impairment among VLBW infants was 3.9%. Prolonged supplemental oxygen use is a marker for predicting hearing impairment; this requires detailed analysis of the pathophysiologic features, to reduce the prevalence of

  7. Students with hearing impairment at a South African university: Self-identity and disclosure

    PubMed Central

    2016-01-01

    Background A growing number of students with hearing loss are being granted access to higher education in South Africa due to the adoption of inclusive educational policies. However, available statistics indicate that participation by students with hearing impairments in higher education remains low and research suggests that support provisioning for those who do gain access is inadequate. Objectives This article aims to illustrate that the assumed self-identity of students with hearing impairment influences their choice to disclose their disability. The choice not to disclose their hearing loss prevents them from accessing the necessary reasonable accommodations and this in turn may affect their eventual educational success. Method Reported here is a qualitative descriptive case study at a South African university. Purposive sampling methods were employed. Data were gathered from in-depth interviews with seven students with hearing impairment ranging from moderate to profound, using spoken language. Constructivist grounded theory was used as an approach to the process of generating and transforming the data, as well as the construction of theory. Findings All the student participants identified as having a hearing rather than a D/deaf identity cultural paradigm and viewed themselves as ‘normal’. Linked to this was their unwillingness to disclose their hearing impairment and thus access support. Conclusion It is crucially important for academic, support and administrative staff to be aware of both the assumed ‘hearing’ identity and therefore subsequent non-disclosure practices of students with a hearing impairment using the oral method of communication. Universities need to put measures in place to encourage students to voluntarily disclose their hearing impairment in order to provide more targeted teaching and learning support. This could lead to improved educational outcomes for students. PMID:28730053

    Hearing technology can play an essential part in the education of deaf and hard-of-hearing children in inclusive schools. Few studies have examined these children's experiences with this technology. This article explores factors pertaining to children's use of and attitudes toward hearing technologies, such as hearing aids, cochlear implants, teacher-worn microphones, and student-worn microphones. The study included 153 deaf and hard-of-hearing students. All students communicated orally and were in inclusive schools from grades 5-10. The results suggest that males view hearing technology more positively than do females. Having severe hearing loss also promoted positive attitudes toward hearing aids and cochlear implants, but not toward microphones. The students with positive self-descriptions tended to be more satisfied with hearing aids or cochlear implants than the students with negative self-descriptions. The main factors promoting the use of hearing aids were severe hearing loss, positive attitudes toward hearing aids, and the sound quality of hearing aids.

    Background The prevalence of hearing impairment is increasing and an association between hearing impairment and mental health has been reported. Our study aimed to determine the association between hearing impairment and mental health in Korea. Methods This was a cross-sectional study of data from the Korean National Health and Nutrition Examination Survey 2010–2013, with a sample size of 18,563 individuals (6,395 with hearing impairment and 12,168 without hearing impairment), aged ≥20 years. Results The female group with hearing impairment tended to have a higher rate of stress (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.11 to 1.56). The association between hearing impairment and depressive symptoms was higher in elderly males (OR, 1.60; 95% CI, 1.10 to 2.32), while the association of hearing impairment with suicide ideation was higher in elderly females (OR, 1.32; 95% CI, 1.00 to 1.75). Conclusion Elderly individuals with hearing impairment are easily susceptible to poor mental health status. Early targeted intervention to address mental health problems is recommended for people with hearing impairment. PMID:28360980

    Early diagnosis, evaluation and treatment of childhood deafness are essential for a child's normal growth. Etiological diagnosis of hearing loss makes prevention, family scheduling and more effective therapy feasible goals. Etiological assessment of sensorineural deafness still remains difficult although recently with the progress of genetics it has become more efficient. In this retrospective study, the etiology of bilateral, sensorineural hearing loss with indication for hearing aids has been studied in 153 hearing impaired children. Etiological diagnosis was based on family and patient record, physical, audiological and laboratory examinations. Among the 94 children who completed the diagnostic protocol etiological groups revealed the following distribution: non-hereditary acquired hearing impairment was present in 36 children (38%) and hereditary was present in 44 (47%) children. The etiology remained unknown in 14 (15%) children. Non-syndromic autosomal dominant type accounted for 13 (29% of hereditary hearing loss) children, non-syndromic autosomal recessive type for 21 (48%) children and syndromic deafness for 10 (23%) children. Modern diagnostic methods, such as genetic testing, help diminish the number of cases with hearing impairment of unknown etiology, for the benefit of children who receive early and appropriate medical, audiologic, genetic and educational counseling based on the etiology of their hearing loss.

    Although speech motor control has been studied intensively in normal-hearing and hearing-impaired (HI) speakers in America and Europe, essentially no research has been performed using Persian-speaking participants. A total of 46 prelingual hearing-impaired 15-18-year-old males and 15 normally hearing control participants from Iran participated in the study. Three speaking performance measures, oral diadochokinesis (DDK), speaking rate (words per minute), and intelligibility ratings, were obtained for the two groups and compared to previously published research for English-speaking participants. The DDK results in general showed that the normal-hearing group produced the fastest syllable rates, and the profoundly HI group produced the slowest. Similar results were obtained for speaking rates. Speech intelligibility was highest in the normal-hearing group and lowest in the profoundly HI group. Correlation analysis between DDK and speaking rates showed that for HI group only, a slow speaking rate corresponded to slow DDK rates. It is shown that generally there are significant differences in measures of speech motor control in normal-hearing and hearing-impaired participants. These results concord with those from other language groups.

    This overview study provides information on important phoniatric and audiological aspects of early childhood hearing and language development with the aim of presenting diagnostic and therapeutic approaches. The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA). The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV) infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant for hearing and language development and therefore requires treatment. The third topic covered in this article is speech and language development in the first 3 years of life, which is known today to be crucial for later language development and learning to read and write. There is a short overview and introduction to modern terminology, followed by the abnormalities and diagnostics of early speech and language development. Only some aspects of early hearing and language development are addressed here. Important areas such as the indication for a cochlear implant in the first year of life or because of unilateral deafness are not included due to their complexity. PMID:25587365

    Questionnaires evaluating hearing impairment are available in English but there is a need for French standardised questionnaires for researchers as well as for audiologists and other clinicians. The objective of this study is to describe the translation and validation of four questionnaires that assess different aspects of hearing impairment and handicap among elders with hearing loss, by comparing the main score and psychometric evaluation of original and French-Canadian (FC) versions of the World Health Organization Disability Assessment Scale II (WHO-DAS II), the Screening Test for Hearing Problems (STHP), the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (MARS-HA). Vallerand method: translation and back-translation by two translators, revision by a committee of experts and pre-tested with five bilingual older participants. Participants (n = 29) were 65 years of age or older including 21 with hearing aids. The psychometric properties (internal consistency, temporal stability after four weeks) indicate good reliability for most of the translated questionnaires and their subscales, especially the WHO-DAS II. The translations in FC of two hearing loss and two hearing aid questionnaires were validated. It is recommended to pursue the demonstration for temporal stability for the STHP.

    Hearing loss is a common problem in modern society due to the combined effects of noise, aging, disease, and heredity. According to 2005 estimates by the World Health Organization (WHO), 278 million people worldwide have moderate to profound hearing loss in both ears. Incidence increases with age. Approximately 31.4% of people over age 65 have hearing loss and 40% to 50% of people 75 and older have a hearing loss. Only 1 out of 5 people who could benefit from a hearing aids actually wears one. To review literature for articles that focus on hearing aids. Hearing aids have continuously evolved over the past 50 years, in term of styles and technology. Technological advances in hearing aids and HATS (Hearing Assistive Technologies, and Rehabilitation Services) have expanded the range of options available to improve the success of a device use. Today's hearing aids differ significantly from their analog predecessors because the application of digital signal processing has permitted many adaptive and/or automatic features. Included in the benefits of digital hearing aids are improved sound quality, multiple listening programs for different listening environments, advanced noise reduction strategies, acoustic feedback reduction, compatibility with remote control options, and flexibility in manipulation of the frequency, compression, and gain. The hearing aids continue to be developed to enhance the characteristics in terms of rehabilitation and acceptability.

    Hearing impairment may affect children’s communication skills, social development, and educational achievement. Little is known about the prevalence of hearing impairment among Chinese children. Data were taken from the 2006 second China National Survey on Disability (CNSD). Hearing impairment was defined as moderate (41–60 dB HL), severe (61–80 dB HL), profound (81–90 dB HL), or complete (>91 dB HL). Logistic regression was used to estimate the odds ratio (OR) and 95% confidence intervals (CI). A weighted number of 567,915 hearing impairment children were identified, yielding a prevalence of 17.49 per 10,000 people (95% CI: 16.90–18.08), with prevention or treatment options possible for 64.6% of hearing impairment children. The main causes of hearing impairment were hereditary, tympanitis, and drug intoxication. Illiteracy in one or both parents (mother: OR = 1.388, 95% CI: 1.125–1.714, p < 0.0001; father: OR = 1.537, 95% CI: 1.152–2.049, p < 0.0001 relative to no school or primary school), annual family income lower than national average (OR = 1.323, 95% CI: 1.044–1.675, p = 0.0203, relative to higher than national average), household size larger than three people (OR = 1.432, 95% CI: 1.164–1.762, p = 0.0007, relative to smaller than three people) and single-mother family (OR = 2.056, 95% CI: 1.390–3.042, p = 0.0176, relative to intact family) were the independence risk factors for hearing impairment among Chinese children. Lower annual family income, male children, larger household size, single-mother family, and lower levels of maternal and paternal education were independent risk factors for hearing impairment for Chinese children. Further studies on hearing impairment prevention and the relationship between parental social factors and the risk of hearing impairment are needed. PMID:28106811

    As a result of well-known recent federal mandates for appropriate special education to all disabled students, the majority of children who are hearing impaired currently are educated in public school settings, along with hearing students. Consequently, teachers of students who are hearing impaired have expanded their role to include the provision of ongoing support to regular classroom teachers, speech-language pathologists, paraprofessionals and administrators. One model for delivery of these services is that of collaborative consultation. The purpose of this paper is to provide an overview of collaborative consultation, and to delineate some principles that merit consideration by regular and special educators who are involved in the education of students who are hearing impaired.

    The purpose of the this study was to examine the perception of both generic and disease-specific quality of life (QoL) in adults with hearing impairment who are members of the lesbian, gay, bisexual, and transgender (LGBT) community. Eighty-three adults who self-identified as having hearing impairment and as being members of the LGBT community and 80 adults with hearing impairment who do not self-identify as being members of the LGBT community (comparison group) participated in this study. The mean age of the participants in the LGBT group was 64.65 years, and the mean age for the comparison group was 63.26 years. Demographic information about the participants included: self-identification in the LGBT community, age, current and previous gender, relationship status, and hearing aid use. Participants received an audiometric evaluation and completed a disease-specific QoL instrument (Hearing Handicap Inventory for the Elderly/Adults) and a generic QoL instrument (Short-Form 36 Health Survey). The results from this study indicate that factors such as gender, relationship status, and hearing aid use are related to the perception of QoL for individuals with hearing impairment who are members of the LGBT community. Differences were found between the participants in the LGBT group and the comparison group. After reading this article, readers should be able to: (1) describe the disease-specific QoL affects of hearing loss on members of the LGBT community compared with a group of adults with hearing impairment who are not members of the LGBT community, (2) describe the gender diffferences in perception of QoL for members of the LGBT community and participants not in the LGBT community, and (3) discuss clinical implications of the findings.

Study design Cross-sectional observational study. Setting Two public hospitals and 1 nonprofit center in Lima, Peru, between August 2009 and April 2010. Subjects A total of 139 HIV-infected children, ages 4 to 19 years. Methods Hearing impairment and otologic health were assessed with pure tone audiometry, tympanometry, and otoscopy. The primary outcome was hearing loss, defined as average threshold >25dB for 0.5, 1, 2, and 4 kHz, in one or both ears. Historical and socioeconomic information was obtained through parental survey and medical chart review. Statistical analysis included univariate analysis and multivariate logistic regression. Results Fifty-four (38.8%) of 139 children had hearing impairment. On multivariate analysis, risk factors included: tympanic membrane perforation (odds ratio [OR] 7.08; 95% confidence interval [CI], 1.65-30.5; P = .01), abnormal tympanometry (OR 2.71; 95% CI, 1.09-6.75; P = .03), cerebral infection (OR 11.6; 95% CI, 1.06-126; P = .05), seizures (OR 5.20; 95% CI, 1.21-22.4; P = .03), and CD4 cell count <500 cells/mm3 (OR 3.53; 95% CI, 1.18-10.5; P = .02). Conclusions The prevalence of hearing impairment in HIV-infected children in Lima, Peru was 38.8%. Middle ear disease, prior cerebral infection, and low CD4 cell count were significantly associated with hearing impairment. The high prevalence of hearing impairment emphasizes the need for periodic hearing assessment in the routine clinical care of HIV-infected children. PMID:22128111

    Binaural speech intelligibility of individual listeners under realistic conditions was predicted using a model consisting of a gammatone filter bank, an independent equalization-cancellation (EC) process in each frequency band, a gammatone resynthesis, and the speech intelligibility index (SII). Hearing loss was simulated by adding uncorrelated masking noises (according to the pure-tone audiogram) to the ear channels. Speech intelligibility measurements were carried out with 8 normal-hearing and 15 hearing-impaired listeners, collecting speech reception threshold (SRT) data for three different room acoustic conditions (anechoic, office room, cafeteria hall) and eight directions of a single noise source (speech in front). Artificial EC processing errors derived from binaural masking level difference data using pure tones were incorporated into the model. Except for an adjustment of the SII-to-intelligibility mapping function, no model parameter was fitted to the SRT data of this study. The overall correlation coefficient between predicted and observed SRTs was 0.95. The dependence of the SRT of an individual listener on the noise direction and on room acoustics was predicted with a median correlation coefficient of 0.91. The effect of individual hearing impairment was predicted with a median correlation coefficient of 0.95. However, for mild hearing losses the release from masking was overestimated.

    This work aimed to highlight a challenging asymptomatic problem which is early detection of hearing impairment in toddlers with protein energy malnutrition (PEM) as a neuro-cognitive effect of PEM on developing brain in relation to hemoglobin level. 100 toddlers, aged 6-24 months, fifty with moderate/severe PEM and fifty healthy children, were included in study. Both TEOAEs and ABR testing were used to assess auditory function. Study reported an association between malnutrition and hearing impairment, 26% of cases had conductive deafness secondary to otitis media with effusion using tympanometry; 84.6% showed type B and 15.4% type C which may suggest developing or resolving otitis media. Their ABR showed 46% mild and 53% moderate impairment. 32% of PEM cases had sensory neural hearing loss and with type (A) tympanometry. Those were assessed using ABR; 58% had mild, 34% moderate and 8% profound impairment. 10% of PEM cases had mixed hearing loss with 50% type B and 50% type C tympanometry and their ABR showed moderate to profound impairment. TEOAEs latencies at different frequencies correlate negatively with hemoglobin level. Toddlers with moderate/severe PEM had hearing impairments of different types and degrees. Neuro-physiological methods could be early and safe detectors of auditory disorders especially in high-risk toddlers. Anemia increases risk for auditory dysfunction.

    This study was aimed at investigating the ability of lexical tone perception in listeners with sensorineural hearing impairment and auditory. neuropathy spectrum disorder. Three groups of subjects were recruited in this study, including 11 subjects with normal hearing, 14 subjects with sensorineural hearing impairment, and 25 subjects with auditory neuropathy spectrum disorder. Ten monosyllabic syllables were selected, and combined with four lexical tones which were made up of 40 tone tokens as the original test materials. Then, these original words were recorded using one adult male and one adult female native Beijing Mandarin speaker. The speakers were asked to record these 40 monosyllabic words multiple times, and the 80 tokens in which the durations of four tones in each monosyllabic word were within 5ms precision were chosen as the test tone tokens. The subjects were asked to perform a four-alternative forced-choice study and select which tone they had heard. The mean and standard deviation of the tone perception correct scores for normal-hearing subjects, subjects with sensorineural hearing impairment, and subjects with auditory neuropathy spectrum disorder were (97.3 ± 2.8)%, (88.0 ± 9.9)%, and (65.7 ± 17.1)%, respectively. Significant differences in tone perception scores were found to be between subjects with normal hearing and subjects with sensorineural hearing impairment (P < 0.01) and between subjects with auditory neuropathy spectrum disorder (P < 0.01). In addition, a significant difference was found to be between subjects with sensorineural hearing impairment and auditory neuropathy spectrum disorder (P < 0.05). A significantly negative correlation was observed between tone perception score and pure tone hearing thresholds for both subjects with sensorineural hearing loss (r = -0.756, P < 0.01) and subjects with auditory neuropathy spectrum disorder (r = -0.546, P < 0.01).

    To test, whether modern Internet telephony with a broadband transmission (0.1-8 kHz) of speech improves speech perception in comparison to conventional telephony (0.3-3.5 kHz) in hearing-impaired and normal-hearing adults. Experimental clinical study. Audiologic laboratory in a tertiary referral center in Bern, Switzerland. Twenty-one adult hearing-impaired patients consisting of 11 users of cochlear implants and 10 users of hearing aids were selected from the institution's database based on pure tone audiograms, speech perception scores, and device settings. Ten normal-hearing adults served as controls. Superiority trial of speech perception assessed with Internet versus conventional telephone quality and noninferiority trial of Internet telephone versus frequency restricted, uncompressed audio CD quality. A modern broadband codec was chosen to simulate Internet telephone quality, and ideal network conditions without packet loss were assumed. Speech perception scores of a monosyllabic word test in quiet and a sentence test in background noise assessed in different audio qualities. : Test scores were, on average, 15% (4-33) higher in the monosyllabic word and 25% (8-51) higher in the sentence test using Internet versus conventional telephone quality across all subject groups. Speech perception was not significantly different when Internet telephone quality was compared with high-cut CD quality. Internet telephony offers significantly improved speech perception to hearing-impaired and normal-hearing adults under ideal laboratory conditions through doubling the frequency range and through conserving audio quality during digital sound processing.

    Hearing loss from birth up to the age of 3 years has a negative effect on speech/language development and results in sensory, cognitive, emotional, and academic defects in adulthood by causing delayed development of communicative-linguistic abilities. The present study was performed in order to assess the effect of early intervention on language development in Persian children aged 6-7 years with severe sensorineural hearing loss. Thirty boys and girls aged 6-7 years participated in this study, all of them had severe congenital sensorineural hearing loss in both ears. All children were using bilateral behind-the-ear hearing aid, and had similar economic/socio-cultural backgrounds. Subjects were categorized into two groups based on the age of identification/intervention of hearing loss (3-6 and 12-15 months of age). The Persian TOLD-P3 test was used to evaluate language development in all subjects. Data collection was accomplished by observation, completion of questionnaires, and speech recording. There was a significant difference in language development in 11 sub-tests and five lingual gains on the Persian TOLD-P3 test between early (3-6 months of age) and late identified/intervened (12-15 months of age) hearing-impaired children (P[Formula: see text]0.05). Early identified/intervened hearing-impaired children had a notable preference in all assessed sub-tests and lingual gains. Early identification/intervention of hearing loss before the age of 6 months has a significant positive effect on a child's language development in terms of picture/relational/oral vocabulary, grammatical comprehension, sentence combining, grammatical completion, phonologic analysis, word differentiation, word production, semantics, and syntax. Moreover, early identification/ intervention of hearing loss develops the hearing-impaired child's lingual gains in visual vocabulary, grammatical completion, word differentiation, phonologic analysis, and word production.

    The speech intelligibility index (SII) is an often used calculation method for estimating the proportion of audible speech in noise. For speech reception thresholds (SRTs), measured in normally hearing listeners using various types of stationary noise, this model predicts a fairly constant speech proportion of about 0.33, necessary for Dutch sentence intelligibility. However, when the SII model is applied for SRTs in quiet, the estimated speech proportions are often higher, and show a larger inter-subject variability, than found for speech in noise near normal speech levels [65 dB sound pressure level (SPL)]. The present model attempts to alleviate this problem by including cochlear compression. It is based on a loudness model for normally hearing and hearing-impaired listeners of Moore and Glasberg [(2004). Hear. Res. 188, 70-88]. It estimates internal excitation levels for speech and noise and then calculates the proportion of speech above noise and threshold using similar spectral weighting as used in the SII. The present model and the standard SII were used to predict SII values in quiet and in stationary noise for normally hearing and hearing-impaired listeners. The present model predicted SIIs for three listener types (normal hearing, noise-induced, and age-induced hearing loss) with markedly less variability than the standard SII.

    Audiological parameters alone do not determine the choice to use hearing aids (HA). Subjective hearing-related QoL is a major factor that determines whether or not an older person will continue to wear HA. This study aimed to identify which audiological parameters and quality-of-life (QoL) measures determine whether or not older persons will continue wearing HA. Charts of 157 patients aged ≥65 years who attended the HA service unit at the Otolaryngology Department were retrospectively reviewed. After HA fitting and a trial, the patients were divided into groups, depending upon whether or not they wanted to continue wearing the HA (users, 58.2%; non-users, 41.8%) and then audiological parameters were compared between them. At least 4 months after the HA fitting, the self-reported QoL questionnaire, Hearing Handicap Inventory for the Elderly (HHIE), was mailed to all 157 patients and HHIE scores were compared between HA users and non-users. Speech discrimination score and dynamic range did not significantly differ between HA users and non-users. A difference in the average hearing threshold was marginally significant. The response rate to the HHIE was 65.2%. Total HHIE and emotional scores were higher (more impaired) among HA users than non-users.

    The main objective of this study was to investigate the extent to which hearing impairment influences the duration of sentence processing. An eye-tracking paradigm is introduced that provides an online measure of how hearing impairment prolongs processing of linguistically complex sentences; this measure uses eye fixations recorded while the participant listens to a sentence. Eye fixations toward a target picture (which matches the aurally presented sentence) were measured in the presence of a competitor picture. Based on the recorded eye fixations, the single target detection amplitude, which reflects the tendency of the participant to fixate the target picture, was used as a metric to estimate the duration of sentence processing. The single target detection amplitude was calculated for sentence structures with different levels of linguistic complexity and for different listening conditions: in quiet and in two different noise conditions. Participants with hearing impairment spent more time processing sentences, even at high levels of speech intelligibility. In addition, the relationship between the proposed online measure and listener-specific factors, such as hearing aid use and cognitive abilities, was investigated. Longer processing durations were measured for participants with hearing impairment who were not accustomed to using a hearing aid. Moreover, significant correlations were found between sentence processing duration and individual cognitive abilities (such as working memory capacity or susceptibility to interference). These findings are discussed with respect to audiological applications. © The Author(s) 2015.

    To determine whether hearing impairment, highly prevalent in older adults, is associated with activity levels. Cross-sectional. National Health and Nutritional Examination Survey (2005-06). Individuals aged 70 and older who completed audiometric testing and whose physical activity was assessed subjectively using questionnaires and objectively using body-worn accelerometers (N=706). Hearing impairment was defined according to the speech-frequency (0.5-4 kHz) pure-tone average in the better-hearing ear (normal <25.0 dB, mild 25.0-39.9 dB, moderate or greater ≥40 dB). Main outcome measures were self-reported leisure time physical activity and accelerometer-measured physical activity. Both were quantified using minutes of moderate-intensity physical activity and categorized as inactive, insufficiently active, or sufficiently active. Ordinal logistic regression analyses were conducted and adjusted for demographic and cardiovascular risk factors. Individuals with moderate or greater hearing impairment had greater odds than those with normal hearing of being in a lower category of physical activity as measured according to self-report (OR=1.59, 95% CI=1.11-2.28) and accelerometry (OR=1.70, 95% CI=0.99-2.91). Mild hearing impairment was not associated with level of physical activity. Moderate or greater hearing impairment in older adults is associated with lower levels of physical activity independent of demographic and cardiovascular risk factors. Future research is needed to investigate the basis of this association and whether hearing rehabilitative interventions could affect physical activity in older adults. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Childhood bacterial meningitis (BM) damages hearing, but the potential of different agents to cause impairment in developing countries is poorly understood. We compared the extent of hearing impairment in BM caused by Haemophilus influenzae type b (Hib), Streptococcus pneumoniae or Neisseria meningitidis among children aged 2 months to 13 years in Luanda, Angola. Hearing of 685 ears of 351 (78%) survivors among 723 enrolled patients was tested by brainstem-evoked response audiometry on day 7 of hospitalization. The causative agent was sought by cerebrospinal fluid culture, PCR or the latex-agglutination test. Altogether, 45 (12%) of the survivors were deaf (threshold >80 dB), and 20 (6%) had a threshold of 80 dB. The incidence of any kind of hearing loss, with ≥60 dB, was 34% with Hib, 30% with S. pneumoniae, 19% with N. meningitidis and 33% with other bacteria. Examining all ears combined and using the ≥60 dB threshold, the agents showed dissimilar harm (P=0.005), Hib being the most frequent and N. meningitidis the most infrequent cause. Compared to other agents, S. pneumoniae more often caused deafness (P=0.025) and hearing impairment at ≥60 dB (P=0.017) in infants, whereas this level of hearing loss in older survivors was most commonly caused by Hib (P=0.031). BM among children in Angola is often followed by hearing impairment, but the risk depends on the agent. S. pneumoniae is a major problem among infants, whereas Hib is mainly a risk beyond 12 months. N. meningitidis impairs hearing less frequently. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Head movements are intimately involved in sound localization and may provide information that could aid an impaired auditory system. Using an infrared camera system, head position and orientation was measured for 17 normal-hearing and 14 hearing-impaired listeners seated at the center of a ring of loudspeakers. Listeners were asked to orient their heads as quickly as was comfortable toward a sequence of visual targets, or were blindfolded and asked to orient toward a sequence of loudspeakers playing a short sentence. To attempt to elicit natural orienting responses, listeners were not asked to reorient their heads to the 0° loudspeaker between trials. The results demonstrate that hearing-impairment is associated with several changes in orienting responses. Hearing-impaired listeners showed a larger difference in auditory versus visual fixation position and a substantial increase in initial and fixation latency for auditory targets. Peak velocity reached roughly 140 degrees per second in both groups, corresponding to a rate of change of approximately 1 microsecond of interaural time difference per millisecond of time. Most notably, hearing-impairment was associated with a large change in the complexity of the movement, changing from smooth sigmoidal trajectories to ones characterized by abruptly-changing velocities, directional reversals, and frequent fixation angle corrections.

    The Vibrant Soundbridge, a semi-implantable hearing device for subjects with moderate to severe sensorineural hearing impairment was introduced commercially. First audiologic results are presented on 63 patients from 10 European implant centers. Hearing loss was at 0.5, 1, 2, and 4 kHz varying between 43 and 81 dB HL. The patients used the analogue audio processor, type 302. Measured sound-field gain was compared with NAL-R target values. For most patients an acceptable agreement was found. There was a subgroup of patients, however, with relatively low gain. The results suggest that this was related to the suboptimal positioning and fixation of the transducer to the incus.

    Objectives Speech perception in background noise is difficult for many individuals and there is considerable performance variability across listeners. The combination of physiological and behavioral measures may help to understand sources of this variability for individuals and groups and prove useful clinically with hard-to-test populations. The purpose of this study was threefold: (1) determine the effect of signal-to-noise ratio (SNR) and signal level on cortical auditory evoked potentials (CAEPs) and sentence-level perception in older normal-hearing (ONH) and older hearing-impaired (OHI) individuals, (2) determine the effects of hearing impairment and age on CAEPs and perception; and (3) explore how well CAEPs correlate with and predict speech perception in noise. Design Two groups of older participants (15 ONH and 15 OHI) were tested using speech-in-noise stimuli to measure CAEPs and sentence-level perception of speech. The syllable /ba/, used to evoke CAEPs, and sentences were presented in speech-spectrum background noise at four signal levels (50, 60, 70, and 80 dB SPL) and up to seven SNRs (−10, −5, 0, 5, 15, 25, 35 dB). These data were compared between groups to reveal the hearing impairment effect and then combined with previously published data for 15 young normal-hearing individuals (Billings et al., 2013) to determine the aging effect. Results Robust effects of SNR were found for perception and CAEPs. Small but significant effects of signal level were found for perception, primarily at poor SNRs and high signal levels, and in some limited instances for CAEPs. Significant effects of age were seen for both CAEPs and perception, while hearing impairment effects were only found with perception measures. CAEPs correlate well with perception and can predict SNR50s to within 2 dB for ONH. However, prediction error is much larger for OHI and varies widely (from 6 to 12 dB) depending on the model that was used for prediction. Conclusions When background

    2010-01-01

    This article investigated the relationship between age at onset of canonical babbling and audibility of amplified speech in children with hearing impairment. Thirteen children with severe–profound hearing impairment and two children with normal hearing participated in a longitudinal investigation of vocalization development. A nonconcurrent multiple baseline design was used to analyze vocalization recordings obtained during two phases (hearing aid [HA] and cochlear implant [CI]). Audibility during HA and CI use was calculated using the Speech Intelligibility Index (SII). Earlier ages of canonical babble onset were related to greater audibility of the speech signal during HA use. Children who developed canonical babble had an SII of .35 or greater. SII was a statistically significant predictor of age of onset of canonical babble. Results support the concept of an “essential” level of audibility for onset of canonical babble. Findings are discussed relative to their methodological and clinical implications regarding treatment decision making. PMID:20457674

    The study examined the impact of acquired profound hearing loss (APHL) on the relationship between the hearing impaired person and their normally hearing close family member, usually a partner, and identified the kinds of adjustment leading to maintenance or deterioration of the relationship. The participants were 25 people with APHL and 25 family members, interviewed separately in their own home. Analysis of the interview transcripts adopted a grounded theory methodology. The different levels of analysis were linked in terms of a core category based on the social construction of a committed relationship. The conceptual codes were grouped as: (a) aural impairments giving rise to the need for adjustment; (b) pragmatic adjustments to spoken communication and family activities; (c) managing the adjustments without negative consequences; (d) adjustments leading to negative interaction. The results suggest that APHL places considerable strain on relationships and increases their vulnerability to failure, consistent with previous research. They highlight the need for professional support and suggest that a systemic conceptual framework is needed that includes the public response to profound hearing impairment.

It aimed at measuring the prevalence of hearing impairment among students and studying the predisposing factors of hearing problems. The schools of the middle educational region were selected to carry out the study. Hearing tests; audiometry and tympanometry, were used to screen 196 students from different types of schools (113, 55 and 28 students from governmental, language and private schools respectively). A questionnaire was introduced to a subsample of those students (n = 141) including some predisposing factors of hearing problems and answered by parents. The physical environment of schools was studied including noise level, ventilation and crowding. The obtained results showed that the prevalence of failed students in audiometry and tympanometry was 24.49 % and 36.22 % respectively. Moreover, the prevalence of pupils who failed in both tests was 7.65 %. Boys were more likely to have hearing impairments than girls. Positive family history of deafness early in life and the continuous complaining of nasal obstruction were significantly related to hearing impairments among students. A very small percentage of parents (4.17 %) were aware of the presence of a hearing problem in their children. Furthermore, 48 % of failed students in audiometry were poor achievers in schools as stated by their teachers. The study of physical environment in schools revealed noise levels (inside and outside classes) above the acceptable but still within the permissible level. On the other hand, crowding at schools, as measured by the per capita space area, showed a significant association with the hearing problems in students. It is recommended to improve awareness of parents and teachers through health education programs. Screening questionnaire can develop an at risk concept for children, as the use of specialist otologists for screening is likely to be very expensive and they must be

    In a previous study with normal-hearing listeners, we evaluated consonant identification masked by two or more spectrally contiguous bands of noise, with asynchronous square-wave modulation applied to neighboring bands. Speech recognition thresholds were 5.1-8.5 dB better when neighboring bands were presented to different ears (dichotic) than when all bands were presented to one ear (monaural), depending on the spectral width of the frequency bands. This dichotic advantage was interpreted as reflecting masking release from peripheral spread of masking from neighboring frequency bands. The present study evaluated this effect in listeners with sensorineural hearing loss, a population more susceptible to spread of masking. Speech perception (vowel-consonant-vowel stimuli, as in /aBa/) was measured in the presence of fluctuating noise that was either modulated synchronously across frequency or asynchronously. Hearing-impaired listeners (n = 9) and normal-hearing controls were tested at either the same intensity (n = 7) or same sensation level (n = 8). Hearing-impaired listeners had mild-to-moderate hearing loss and symmetrical, flat audiometric thresholds. While all groups of listeners performed better in the dichotic than monaural condition, this effect was smaller for the hearing-impaired (3.5 dB) and equivalent-sensation-level controls (3.3 dB) than controls tested at the same intensity (11.0 dB). The present study is consistent with the idea that dichotic presentation can improve speech-in-noise listening for hearing-impaired listeners, and may be enhanced when combined with amplification.

    The purpose of this study was to determine the 10-yr cumulative incidence of hearing impairment and associations of education, occupation and noise exposure history with the incidence of hearing impairment in a population-based cohort study of 3753 adults ages 48-92 yr at the baseline examinations during 1993-1995 in Beaver Dam, WI. Hearing thresholds were measured at baseline, 2.5 yr-, 5 yr-, and 10-yr follow-up examinations. Hearing impairment was defined as a pure-tone average (PTA)>25 dB HL at 500, 1000, 2000, and 4000 Hz. Demographic characteristics and occupational histories were obtained by questionnaire. The 10-yr cumulative incidence of hearing impairment was 37.2%. Age (5 yr; Hazard Ratio (HR)=1.81), sex (M vs W; HR=2.29), occupation based on longest held job (production/operations/farming vs others; HR=1.34), marital status (unmarried vs married; HR=1.29) and education (<16 vs 16+yr; HR=1.40) were associated with the 10 yr incidence. History of noisy jobs was not associated with the 10-yr incidence of hearing impairment. The risk of hearing impairment was high, with women experiencing a slightly later onset. Markers of socioeconomic status were associated with hearing impairment, suggesting that hearing impairment in older adults may be associated with modifiable lifestyle and environmental factors, and therefore, at least partially preventable.

    To estimate the prevalence and causes of hearing impairment in Fundong Health District, North-West Cameroon. We selected 51 clusters of 80 people (all ages) through probability proportionate to size sampling. Initial hearing screening was undertaken through an otoacoustic emission (OAE) test. Participants aged 4+ years who failed this test in both ears or for whom an OAE reading could not be taken underwent a manual pure-tone audiometry (PTA) screening. Cases of hearing impairment were defined as those with pure-tone average ≥41 dBHL in adults and ≥35 dBHL in children in the better ear, or children under age 4 who failed the OAE test in both ears. Each case with hearing loss was examined by an ear, nose and throat nurse who indicated the main likely cause. We examined 3567 (86.9%) of 4104 eligible people. The overall prevalence of hearing impairment was 3.6% (95% confidence interval [CI]: 2.8-4.6). The prevalence was low in people aged 0-17 (1.1%, 0.7-1.8%) and 18-49 (1.1%, 0.5-2.6%) and then rose sharply in people aged 50+ (14.8%, 11.7-19.1%). Among cases, the majority were classified as moderate (76%), followed by severe (15%) and profound (9%). More than one-third of cases of hearing impairment were classified as unknown (37%) or conductive (37%) causes, while sensorineural causes were less common (26%). Prevalence of hearing impairment in North-West Cameroon is in line with the WHO estimate for sub-Saharan Africa. The majority of cases with known causes are treatable, with impacted wax playing a major role. © 2017 John Wiley & Sons Ltd.

    A pure-tone average of 0.5, 1, 2, and 4 kHz in the better ear (PTA-4) is the international standard criterion set by the World Health Organization (WHO) to describe hearing loss. Presently, there are no epidemiological data on hearing loss in Germany based on this criterion. A representative sample of adults from Oldenburg and Emden were invited for a hearing assessment. This article analyzes the association between hearing loss and age, sex, noise, occupation, and educational level. Age- and sex-specific prevalence rates following the WHO classification are compared with international findings. According to the WHO classification, the prevalence of hearing impairment in the study cohort (n=1,866) is approx. 16%. In men, who more commonly work in noisy jobs, a higher prevalence rate is observed than in women of the same age. Nevertheless, sex differences in the present study are smaller than those reported in most international studies. PTA-4 is approximately the same for men and women when effects of occupational noise are controlled, but differences in prevalence between occupational areas are still significant. Compared with international findings, age-specific prevalence rates in HÖRSTAT are low. In the synopsis of epidemiological studies of the past 25 years, a trend toward decreasing prevalence in middle and higher age groups can be observed.

    Extensive measures of speech production and perception were secured before and after the individualized training of 75 hearing-impaired postsecondary students to evaluate the efficacy of therapy. Additional measures of hearing, reading, writing, nonverbal intelligence, and manual and simultaneous communication reception were made to explore variables that might influence response to training. Significant improvements in vowel, word and sentence production, and word and sentence perception were observed. Pretherapy measures of speech production and perception were the most powerful factors explaining variability in posttest scores. Other variables predicting the outcome of speech therapy were residual hearing and linguistic competence. Clinical implications are discussed.

    Hearing function of an institutionalized population with intellectual disability, consisting of 70 subjects with a mean age of 70.1 (range 60-92) years at initial evaluation, was assessed during a 10-year longitudinal study. One subject had Down's syndrome and could not be assessed as a result of dementia. The total prevalence of mild to severe hearing loss (33.3% in the 60-70 age group and 70.4% in those over age 70) was comparable to reported data from an ageing population without intellectual disability in the United Kingdom (37%, respectively 60%). However, the proportion of moderate to severe losses might be higher (16.7% vs. 7% in the 60-70 age group and 33.3% vs. 18% in the older age group). Excess impairment was caused by severe congenital and childhood hearing impairment on one hand, and by conductive losses, probably caused by unrecognized chronic middle ear infections, superposed upon presbyacusis, on the other. Impacted ear wax was also a major problem. The incidence of new cases with hearing loss during follow-up was 50%. After individual habituation training hearing aids were used without difficulties by 20 out of 24 subjects. The importance of active screening and treatment of middle ear infections and hearing impairment from a young age onwards, and regular cleaning of the external ear canals is stressed.

    This study examined the effects of mild-to-moderate sensorineural hearing loss on vowel perception abilities of young, hearing-impaired (YHI) adults. Stimuli were presented at a low conversational level with a flat frequency response (approximately 60 dB SPL), and in two gain conditions: (a) high level gain with a flat frequency response (95 dB SPL), and (b) frequency-specific gain shaped according to each listener's hearing loss (designed to simulate the frequency response provided by a linear hearing aid to an input signal of 60 dB SPL). Listeners discriminated changes in the vowels /smcapi ee eh invv æ/ when F1 or F2 varied, and later categorized the vowels. YHI listeners performed better in the two gain conditions than in the conversational level condition. Performances in the two gain conditions were similar, suggesting that upward spread of masking was not seen at these signal levels for these tasks. Results were compared with those from a group of elderly, hearing-impaired (EHI) listeners, reported in Coughlin, Kewley-Port, and Humes [J. Acoust. Soc. Am. 104, 3597-3607 (1998)]. Comparisons revealed no significant differences between the EHI and YHI groups, suggesting that hearing impairment, not age, is the primary contributor to decreased vowel perception in these listeners.

    This paper explains about a comparison between assistive video for hearing-impaired learners (AV4HI) and assistive courseware for hearing-impaired learners (AC4HI). The rationale is that previous statement was made after learners experience normal courseware, not the courseware specifically designed for them. Hence, perhaps if the courseware is designed special for them, the hearing-impaired learners would experience differently, and behave more positive upon the AC4HI. Hence, this paper aims at describing the execution of the comparison. It involves a 3-stage process: designing the AC4HI, developing the AC4HI, and user experience. In the end, it was found that users are happy with both, but in terms of content acquisition, they prefer to have notes in the learning material.

    Despite the increasing number of reports of families with hearing impairment and mitochondrial DNA (mtDNA) mutations, the frequency of these mutations as causes of non-syndromic sensorineural hearing impairment (NSSHI) remains unknown. Mutations such as A1555G, A7445G and 7472insC have been found in several unrelated families implying they are more frequent than initially thought. We describe a family with NSSHI due to the presence of the homoplasmic mtDNA A7445G mutation in the tRNASer(UCN) gene. This is the fourth such family described with this mutation, all of different genetic backgrounds. Our study also demonstrates the difficulties sometimes encountered in establishing mitochondrial inheritance of hearing impairment in some families.

    In order to optimize the use of tactual aids for the deaf, it is important to have a battery of assessments to determine the potential contribution of the aids to acoustic perception and speech identification. We have designed such a battery to be used with young hearing-impaired children. The tasks were developed so that they could be implemented with standard audiometric equipment and applied to subjects of varying age and to different types of tactual aids. Illustrative results from four profoundly hearing-impaired children showed that tactual vocoders allowed detection of high frequencies that were not available to the subjects through aided audition. In most cases with these subjects, performance on simple detection and discrimination tasks showed facilitative effects with tactual vocoders. Facilitative effects were further evidenced in more complex phonemic identification tasks for all subjects. The tasks can be used to determine possible benefits of tactual aids for individual hearing-impaired children.

    The aim was to determine whether there are indications that hearing-impaired children experience difficulties in accessing dental care and/or in receiving dental treatment. The study was carried out by means of a questionnaire. Parents of 84 children contacted through the National Deaf Children's Society returned completed questionnaires. Eighty-two children (98%) had visited a dentist. Nearly two-thirds (63%) were reported to have at least one problem in communication while receiving dental care, this increased significantly as the severity of the hearing impairment increased. Fifty-nine children (70%) reported having at least one problem in communication at the doctors'. Fifty-two (62%) reported that the dentist had worn a mask while communicating with the child and 48 (57%) that there had been background noise in the surgery during appointments. Removing masks while talking, reducing background noise and learning to use simple signs may improve communication with hearing-impaired children.

    To estimate the prevalence and severity of hearing impairment (HI), the self-perception of HI, and the willingness to use a hearing aid (HA) in the elderly population in southern Taiwan. This community-based study was performed in a metropolitan hospital. A questionnaire about the perception of HI and the willingness to use a HA was used. The severity of HI in speech-frequency pure-tone average (PTA) was evaluated. The associations between sex, age, severity of HI, self-perception of HI, and the willingness to use a HA were analysed. A total of 599 volunteers were recruited from the health management center; 324 (54.1%) males and 275 (45.9%) females, who were 65 years of age or older. The prevalence of HI >25 dBHL in the elderly was 78%. The predicted levels for elderly persons to perceive HI and hearing difficulties were 34.38 dBHL and 54.38 dBHL, respectively. Males and younger participants were more willing to use HA. The primary reasons for refusing HA use were discomfort (25.1%) and a self-perception that the HA was unnecessary (19.7%). The prevalence of HI was high among the elderly population in southern Taiwan. Age and sex were the determinants of HA use.

    External degradations in incoming speech reduce understanding, and hearing impairment further compounds the problem. While cognitive mechanisms alleviate some of the difficulties, their effectiveness may change with age. In our research, reviewed here, we investigated cognitive compensation with hearing impairment, cochlear implants, and aging, via (a) phonemic restoration as a measure of top-down filling of missing speech, (b) listening effort and response times as a measure of increased cognitive processing, and (c) visual world paradigm and eye gazing as a measure of the use of context and its time course. Our results indicate that between speech degradations and their cognitive compensation, there is a fine balance that seems to vary greatly across individuals. Hearing impairment or inadequate hearing device settings may limit compensation benefits. Cochlear implants seem to allow the effective use of sentential context, but likely at the cost of delayed processing. Linguistic and lexical knowledge, which play an important role in compensation, may be successfully employed in advanced age, as some compensatory mechanisms seem to be preserved. These findings indicate that cognitive compensation in hearing impairment can be highly complicated—not always absent, but also not easily predicted by speech intelligibility tests only.

All neonatal intensive care unit infants and well babies with risk factors (including well babies who failed neonatal tests) were targeted for follow-up behavioral evaluation once they had reached 8 mo corrected age. Three thousand one hundred and thirty-four (64.4%) of the 4868 surviving infants returned for at least one behavioral hearing evaluation, which employed a well-defined VRA protocol. VRA thresholds or minimum response levels (MRLs) were determined for speech and pure tones of 1.0, 2.0, and 4.0 kHz for each ear using insert earphones. More than 95% of the infants were reliably tested with the VRA protocol; 90% provided complete tests (four MRLs for both ears). Ninety-four percent of the at-risk infants were found to have normal hearing sensitivity (MRLs of 20 dB HL) at 1.0, 2.0, and 4.0 kHz in both ears. Of the infants, 2.2% had bilateral hearing impairment, and 3.4% had impairment in one ear only. More than 80% of the impaired ears had losses of mild-to-moderate degree. This may be the largest study to attempt to follow all at-risk infants with behavioral audiometric testing, regardless of screening outcome, in an effort to validate the results of auditory brain stem response, distortion product otoacoustic emission, and transient evoked otoacoustic emission testing in the newborn period. It is one of only a few studies to report hearing status of infants at 1 yr of age, using VRA on a clinical population. Successful testing of more than 95% of the infants who returned for the VRA follow-up documents the feasibility of obtaining monaural behavioral data in this population.

  10. Hearing impairment risk and interaction of folate metabolism related gene polymorphisms in an aging study

    PubMed Central

    2011-01-01

    Background Recent investigations demonstrated many genetic contributions to the development of human age-related hearing impairment (ARHI), however, reports of factors associated with a reduction in the ARHI risk are rare. Folate metabolism is essential for cellular functioning. Despite the extensive investigations regarding the roles of folate metabolism related gene polymorphisms in the pathophysiology of complex diseases, such as cancer, cardio-cerebrovascular disease, and atherosclerosis, little is known about the association with ARHI. The aim of this study is to investigate the effects of the methionine synthase (MTR) A2756G and methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphisms on the risk of hearing impairment in middle-aged and elderly Japanese. Methods Data were collected from community-dwelling Japanese adults aged 40-84 years who participated in the Longitudinal Study of Aging biennially between 1997 and 2008. We analyzed cumulative data (5,167 samples in accumulated total) using generalized estimating equations. Results The MTHFR 677T allele was significantly associated with a reduced risk of hearing impairment only when the subjects were wild-type homozygotes for MTR A2756G. The per-T allele odds ratio of MTHFR for the risk of developing hearing impairment was 0.7609 (95% CI: 0.6178-0.9372) in the MTR AA genotype. In addition, a subgroup analysis demonstrated that the favorable effect of the MTHFR 677T allele on the risk of developing hearing impairment was independent of folate and homocysteine level, whereas plasma total homocysteine level was independently associated with an increased risk of developing hearing impairment. The interactive effect of gene polymorphisms associated with folate metabolism may modify the risk of developing hearing impairment after middle age. These results contribute to the elucidation of the causes of ARHI. Conclusions The present study has found that the MTHFR 677T allele has a favorable effect on a

    Hearing-impaired students have trouble with question forms, a fact that is well-documented. To date, the implications of this linguistic difficulty on their reading comprehension have been virtually unexplored. This article discusses the importance of questions as a means of acquiring and clarifying information and as a way to develop independent learning processes. The article also discusses roadblocks to learning faced by hearing-impaired students who have difficulty comprehending question forms, especially WH-question forms. Strategies for diagnosing and developing students' ability to understand questions are described, and the importance of parents and teachers working together is explained.

    The effects of audibility and age on masking for sentences in continuous and interrupted noise were examined in listeners with real and simulated hearing loss. The absolute thresholds of each of ten listeners with sensorineural hearing loss were simulated in normal-hearing listeners through a combination of spectrally-shaped threshold noise and multi-band expansion for octave bands with center frequencies from 0.25–8 kHz. Each individual hearing loss was simulated in two groups of three normal-hearing listeners (an age-matched and a non-age-matched group). The speech-to-noise ratio (S∕N) for 50%-correct identification of hearing in noise test (HINT) sentences was measured in backgrounds of continuous and temporally-modulated (10 Hz square-wave) noise at two overall levels for unprocessed speech and for speech that was amplified with the NAL-RP prescription. The S∕N in both continuous and interrupted noise of the hearing-impaired listeners was relatively well-simulated in both groups of normal-hearing listeners. Thus, release from masking (the difference in S∕N obtained in continuous versus interrupted noise) appears to be determined primarily by audibility. Minimal age effects were observed in this small sample. Observed values of masking release were compared to predictions derived from intelligibility curves generated using the extended speech intelligibility index (ESII) [Rhebergen et al. (2006). J. Acoust. Soc. Am. 120, 3988–3997]. PMID:20649229

    Universal newborn hearing screening (UNHS) is of paramount importance for early identification and management of hearing impairment in children. However, infants with slight/mild, progressive, or late-onset hearing impairment might be missed in conventional UNHS. To investigate whether genetic screening for common deafness-associated mutations could assist in identifying these infants, 1017 consecutive newborns in a tertiary hospital were subjected to both newborn hearing screening using a two-step distortion-product otoacoustic emissions (DPOAE) screening and newborn genetic screening (NGS) for deafness. The NGS targeted 4 deafness-associated mutations commonly found in the Taiwanese population, including p.V37I (c.109G>A) and c.235delC of the GJB2 gene, c.919-2A>G of the SLC26A4 gene, and mitochondrial m.1555A>G of the 12S rRNA gene. The results of the NGS were then correlated to the results of the NHS. Of the 1017 newborns, 16 (1.6%) had unilateral DPOAE screening failure, and 22 (2.2%) had bilateral DPOAE screening failure. A total of 199 (19.6%) babies were found to have at least 1 mutated allele on the NGS for deafness, 11 (1.1%) of whom were homozygous for GJB2 p.V37I, 6 (0.6%) compound heterozygous for GJB2 p.V37I and c.235delC, and 1 (0.1%) homoplasmic for m.1555A>G, who may potentially have hearing loss. Among them, 3 babies, 5 babies, and 1 baby, respectively, passed the NHS at birth. Comprehensive audiological assessments in the 9 babies at 3 months identified 1 with slight hearing loss and 2 with mild hearing loss. NGS for common deafness-associated mutations may identify infants with slight/mild or potentially progressive hearing impairment, thus compensating for the inherent limitations of the conventional UNHS.

    Hearing loss as a result of meningitis, now the leading nongenetic cause of deafness in infants and young children, may be reduced by the introduction of the HiB (Hemophilus influenzae type B) vaccine. It is highly effective, relatively safe, and recommended for most children over 24 months and high risk children 18-24 months old. (VW)

    The ability to discriminate the spectral shapes of complex sounds is critical to accurate speech perception. Part of the difficulty experienced by listeners with hearing loss in understanding speech sounds in noise may be related to a smearing of the internal representation of the spectral peaks and valleys because of the loss of sensitivity and…
