The Relationship

Abstract Hearing impairment is a risk factor for dementia but the mechanism underlying this association is unknown. We investigated the relationship between hearing and cognitive performance and brain β-amyloid deposition in 252 adults aged 67-88 years (37% black race) without dementia from three U.S. communities. Global cortical standardized uptake value ratios (SUVRs) were calculated from florbetapir-positron emission tomography scans, with elevated SUVR defined as >1.2 (the median value). Air conduction hearing threshold levels for the frequencies of 0.5, 1, 2 and 4 kHz were obtained by pure tone audiometry and averaged for the better-hearing ear to yield a pure tone average (PTA) in decibels hearing level (dB). A composite cognitive score was created from ten neuropsychological tests summarized using latent variable methods. Multivariable-adjusted linear and Poisson regression with robust standard errors were used to estimate the average difference in cognitive scores and prevalence of elevated SUVR, respectively, by hearing impairment status. In analyses adjusted for age, sex, education and APOE ε4 status, hearing was not associated with elevated SUVR [prevalence ratio per 10 db increase (worse hearing) = 0.94 (95% CI: 0.84, 1.04)]. Results did not differ by race. In contrast, each 10 db increase in hearing impairment was associated with 0.08 standard deviation (95% CI: 0.02, 0.15) lower cognitive score, after adjustment for demographic and cardiovascular factors. Poorer hearing is associated with poorer cognitive performance but not with amyloid deposition, suggesting that the mechanism underlying the relationship between hearing and cognition may be independent of Alzheimer’s-related pathologic brain changes.

Hearing Problems

Background: There are not many population-based epidemiological studies on the association between self-reported hearing problems and measured hearing thresholds in older adults. Previous studies have shown that the relationship between self-reported hearing difficulties and measured hearing thresholds is unclear and, according to our knowledge, there are no previous population-based studies reporting hearing thresholds among subjects with hyperacusis. Purpose: The aim was to investigate the prevalence of self-reported hearing problems, that is, hearing difficulties, difficulties in following a conversation in noise, tinnitus, and hyperacusis, and to compare the results with measured hearing thresholds in older adults. Research Design: Cross-sectional, population-based, and unscreened. Study Sample: Random sample of subjects (n = 850) aged 54-66 yr living in the city of Oulu (Finland) and the surrounding areas. Data Collection and Analysis: Otological examination, pure tone audiometry, questionnaire survey Results: The prevalence of self-reported hearing problems was 37.1% for hearing difficulties, 43.3% for difficulties in following a conversation in noise, 29.2% for tinnitus, and 17.2% for hyperacusis. More than half of the subjects had no hearing impairment, or HI (BEHL[better ear hearing level]0.5–4 kHz < 20 dB HL) even though they reported hearing problems. Subjects with self-reported hearing problems, including tinnitus and hyperacusis, had significantly poorer hearing thresholds than those who did not report hearing problems. Self-reported hearing difficulties predicted hearing impairment in the pure-tone average at 4, 6, and 8 kHz, and at the single frequency of 4 kHz. Conclusions: The results indicate that self-reported hearing difficulties are more frequent than hearing impairment defined by audiometric measurement. Furthermore, self-reported hearing difficulties seem to predict hearing impairment at high frequencies (4–8 kHz) rather than at the frequencies of 0.5–4 kHz, which are commonly used to define the degree of hearing impairment in medical and legal issues.

Background and Objectives Self-reported hearing levels determined by self-report questionnaires are not always correlated with the audiometric hearing level. It is necessary to ascertain the subjectively perceived normal hearing threshold to determine the need for hearing aids at the appropriate time. The objective is to identify the level of correlation between the self-reported hearing level and the audiometric hearing level and ascertain the subjectively perceived normal hearing threshold for each age group.Subjects and Method This cross-sectional study, using the data from the Korea National Health and Nutrition Examination Survey V, looked at participants with hearing loss who were aged ≥40 years. Pure tone audiometry was conducted bilaterally. Self-reported hearing level was ascertained via survey enquiring about hearing loss. The level of correlation between self-reported hearing level and audiometric hearing level, age-specific patterns of hear-ing self-evaluation and subjectively perceived normal hearing values at which participants complained of hearing loss were main outcomes.Results Mean audiometric thresholds (MATs) increased with the age and degree of self-reported hearing level. The accuracy of self-reported hearing level compared to the audiometric threshold decreased with age both in the better-ear and worse-ear groups. Younger participants tended to overestimate their hearing impairment, while older participants tended to underestimate it. Subjectively perceived normal hearing thresholds increased with age and they were very close to the MATs for each age group.Conclusion Results can be useful for devising different age-group specific pure tone audi-ometry-based diagnostic criteria for self-reported hearing loss, which can be used to determine the need for hearing aid in a timely manner.

Abstract Introduction: Navy personnel are exposed to several risk factors that increase hearing thresholds and impair hearing. The aim of the study was to determine the prevalence of hearing impairment among Nigerian Navy personnel. Materials and Method: This was a cross sectional study of Nigerian Navy personnel working in various ships. Structured, self-administered questionnaire was used to obtain information on hearing. All the subjects had ear examination and pure tone audiometry of both ears. Results: The prevalence of hearing impairment was 22(14.7%) in the right and 17(11.3%) in the left ears. The Pure Tone Average for the right and left ear were 19.0±8.6dB and 17.4±6.7dB respectively. There was a statistically significant association between noisy work place and total hearing loss (p<.01), pure tone average in the left ear (p<.05) and frequencies of 3000 Hz (p<.05), 2000 Hz (p<.001) and 1000Hz (p<.05) in the left ear. The association between past history of ear infections and pure tone average in the left ear (p<.05) and the frequency 2000 Hz (p<.005) in the left ear were significant. The length of service years, occupational group, age, sex report of change in hearing, non-use of hearing protection and presence of tinnitus did not show significant association with pure tone averages nor on the frequencies tested. Conclusion: The significant unilateral hearing impairment on the right ear suggests the need for more research on hearing impairment in the Nigerian Navy as well as development of a comprehensive hearing conservation programme.

Objectives: To identify the etiologies of hearing impairment (HI) in schools for students who are deaf and to use a systematic review to summarize reports on the etiologies and clinical and genetic features of HI in Mali.Methods: We included individuals with HI that started before the age of 15 years old. Patients were carefully evaluated under standard practices, and pure-tone audiometry was performed where possible. We then searched for articles published on HI in the Malian population from the databases' inception to March 30, 2020.Results: A total of 117 individuals from two schools for the deaf were included, and a male predominance (sex ratio 1.3; 65/52) was noted. HI was pre-lingual in 82.2% (n = 117), and the median age at diagnosis was 12 years old. The etiologies were environmental in 59.4% (70/117), with meningitis being the leading cause (40%, 20/70), followed by cases with genetic suspicion (29.3%, 21/117). In 11.3% (8/117) of patients, no etiology was identified. Among cases with genetic suspicion, three were syndromic, including two cases of Waardenburg syndrome, while 15 individuals had non-syndromic HI. An autosomal recessive inheritance pattern was observed in 83.3% of families (15/18), and consanguinity was reported in 55.5% (10/18) of putative genetic cases.Conclusion: This study concludes that environmental factors are the leading causes of HI in Mali. However, genetic causes should be investigated, particularly in the context of a population with a high consanguinity rate.

Using the Hearing Handicap Inventory for Adults (HHIA), we assessed self-perceived hearing handicap in a sample of 63 patients having either unilaterally normal hearing or a mild hearing loss (pure tone average ≤40 dB hearing level). Large intersubject variability in responses to the HHIA confirmed observations that reactions to minimal hearing impairment vary greatly among patients. The individual differences in responses highlight the importance of quantifying the perceived communication and psychosocial handicap, which cannot be determined from the audiogram alone. An item examination of responses to the HHIA revealed a number of emotional and social-situational problems encountered by patients with minimal hearing loss.

Background: Tinnitus is a common complaint and often of no clinical significance. There are a number of unresolved issues concerning the etiology, pathogenesis, and natural history of tinnitus. There are a few current population-based estimates of the prevalence of tinnitus done in representative large geographic areas, but there is little data from multi-area, large sample studies of tinnitus in China. Purpose: To investigate the prevalence of tinnitus and related factors in a Chinese population. These data would be used to plan and evaluate health-care services. Research Design: We carried out an epidemiologic study of tinnitus as part of an epidemiologic study of ear and hearing disorders that was undertaken in Jiangsu Province, China. A question about tinnitus history was included in a comprehensive questionnaire about hearing. All participants also had both pure tone audiometry and an otological examination. Study Sample: The sample consisted of 6333 people 10 yr of age or older, selected by the methods of probability proportional to size. Data Collection and Analysis: All participants answered a questionnaire concerning their tinnitus and had pure tone audiometry testing and an ear examination. All data were entered using EPIDATD 3.0 software and analyzed by a chi-squared test and test for trends. Results: The overall prevalence of tinnitus was 14.5%, and the standardized rates were 11.4% in the whole country and 12.4% in Jiangsu province. Its prevalence increased with age. The prevalence of tinnitus was 11.9 and 15.6% in urban and rural residents, respectively There was no significant difference in prevalence between men and women. Hearing impairment, history of middle ear infections, and noise exposure were the main risk factors for tinnitus. Conclusion: Tinnitus is a common problem in the population. With the aging of the population, the prevalence of tinnitus will increase. The prevention of tinnitus should focus on hearing impairment screening, otitis media treatment, and noise exposure reduction. Health services in rural areas should emphasize prevention more.

Pure Tone Threshold

The efficiency of the Verbal Auditory Screening for Children (VASC) compared to a pure-tone threshold test as a technique to identify hearing impairment among preschool children was investigated with 162 subjects. The VASC-1 test correctly identified 84.6% of the total subjects. Of the 41 subjects failed by the pure-tone threshold test, 48.8% were missed by the VASC-1. An analysis of the average hearing threshold loss for 500–2000 Hz or the ears misclassified by the VASC-1 revealed 83.3% ranged from 0 to 13 dB. The VASC-1 and the verbal portion of the VASC-2 appear to be fairly equivalent forms.
