Objectives To examine whether adolescents exceed recommended noise exposure limits when using personal listening devices (PLDs) and to investigate the relationship between objectively measured PLD use and hearing thresholds Study Design Cross-sectional study. Setting This study was embedded within an ongoing prospective birth cohort study in Rotterdam, the Netherlands. Data were collected from May 2017 to September 2019. Methods A smartphone application was developed to measure daily noise exposure from PLDs. Listening habits were monitored among 314 adolescents with a mean age of 13 years 7 months (SD, 5 months), of whom 51.6% were male. Hearing acuity was measured by pure tone audiometry, and tympanometry was performed in both ears. Results Within the study group, 2.2% adolescents exceeded the recommended daily noise dose (85 dBA as an 8-hour time-weighted average) among all days when the application was active and 9.9% when among only the listening days. No significant correlation was found between the daily noise dose from PLDs and pure tone thresholds. Conclusions The majority of adolescents exhibited listening habits that could be considered safe. As noise-induced hearing loss develops slowly over time, it could be that the effects of PLD use on hearing are not evident yet in this young population with a relatively short duration of PLD use.

ABSTRACT Objective To assess central auditory function in Friedreich's ataxia. Methods A cross-sectional, retrospective study was carried out. Thirty patients underwent the anamnesis, otorhinolaryngology examination, pure tone audiometry, acoustic immittance measures and brainstem auditory evoked potential (BAEP) assessments. Results The observed alterations were: 43.3% in the pure tone audiometry, bilateral in 36.7%; 56.6% in the BAEP test, bilateral in 50%; and 46.6% in the acoustic immittance test. There was a significant difference (p < 0.05) in the comparison between the tests performed. Conclusion In the audiological screening, there was a prevalence of the descending audiometric configuration at the frequency of 4kHz, and absence of the acoustic reflex at the same frequency. In the BAEP test, there was a prevalence of an increase of the latencies in waves I, III and V, and in the intervals of interpeaks I-III, I-V and III-V. In 13.3% of the patients, wave V was absent, and all waves were absent in 3.3% of patients.

Background Sudden sensorineural hearing loss (SSNHL) is an otologic emergency that warrants urgent management. Pure-tone audiometry remains the gold standard for definitively diagnosing SSNHL. However, in clinical settings such as primary care practices and urgent care facilities, conventional pure-tone audiometry is often unavailable. Objective This study aimed to determine the correlation between hearing outcomes measured by conventional pure-tone audiometry and those measured by the proposed smartphone-based Ear Scale app and determine the diagnostic validity of the hearing scale differences between the two ears as obtained by the Ear Scale app for SSNHL. Methods This cross-sectional study included a cohort of 88 participants with possible SSNHL who were referred to an otolaryngology clinic or emergency department at a tertiary medical center in Taipei, Taiwan, between January 2018 and June 2019. All participants underwent hearing assessments with conventional pure-tone audiometry and the proposed smartphone-based Ear Scale app consecutively. The gold standard for diagnosing SSNHL was defined as the pure-tone average (PTA) difference between the two ears being ≥30 dB HL. The hearing results measured by the Ear Scale app were presented as 20 stratified hearing scales. The hearing scale difference between the two ears was estimated to detect SSNHL. Results The study sample comprised 88 adults with a mean age of 46 years, and 50% (44/88) were females. PTA measured by conventional pure-tone audiometry was strongly correlated with the hearing scale assessed by the Ear Scale app, with a Pearson correlation coefficient of .88 (95% CI .82-.92). The sensitivity of the 5–hearing scale difference (25 dB HL difference) between the impaired ear and the contralateral ear in diagnosing SSNHL was 95.5% (95% CI 87.5%-99.1%), with a specificity of 66.7% (95% CI 43.0%-85.4%). Conclusions Our findings suggest that the proposed smartphone-based Ear Scale app can be useful in the evaluation of SSNHL in clinical settings where conventional pure-tone audiometry is not available.

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.

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.

AbstractObjective:To examine whether distortion product otoacoustic emissions can serve as a replacement for pure tone audiometry in longitudinal screening for occupational noise exposure related auditory deficit.Methods:A retrospective review was conducted of pure tone audiometry and distortion product otoacoustic emission data obtained sequentially during mandatory screening of brickyard workers (n = 16). Individual pure tone audiometry thresholds were compared with distortion product otoacoustic emission amplitudes, and a correlation of these measurements was conducted.Results:Pure tone audiometry threshold elevation was identified in 13 out of 16 workers. When distortion product otoacoustic emission amplitudes were compared with pure tone audiometry thresholds at matched frequencies, no evidence of a robust relationship was apparent. Seven out of 16 workers had substantial distortion product otoacoustic emissions with elevated pure tone audiometry thresholds.Conclusion:No clinically relevant predictive relationship between distortion product otoacoustic emission amplitude and pure tone audiometry threshold was apparent. These results do not support the replacement of pure tone audiometry with distortion product otoacoustic emissions in screening. Distortion product otoacoustic emissions at frequencies associated with elevated pure tone audiometry thresholds are evidence of intact outer hair cell function, suggesting that sites distinct from these contribute to auditory deficit following ototrauma.

Background: Prisoners, due to confinement are isolated from contact with the society and access to many of the facilities, including medical care. This study aimed to evaluate the hearing threshold of inmates of Kaduna convict prison. Method: It was a cross-sectional study of prison inmates at the Kaduna convict prison between April 2017 and February 2019. Ethical approvals were obtained from relevant bodies and all consented inmates aged 18 – 55years in the Kaduna convict prison were enrolled. Equal number of control matched for age and gender were enrolled from the communities in Kaduna North Local Government Area. Data were collated using a structured questionnaire. A diagnostic Pure Tone Audiometry was performed to assess their hearing threshold. Statistical Package for Social Sciences (SPSS) version 20.0 was used for analysis. Results: Four hundred and thirty inmates and equal number of control group were enrolled. The mean age for the inmates and controls were 30.2±7.5 and 30.4±8.02 years respectively. There were 383 males and 47 females in both groups. Among the 860 ears of the inmates, 238(27.7%) ears had hearing loss while in the control group, 95/ (11.1%) ears had impaired hearing. Conductive hearing loss was the commonest among the inmates 111(46.6%) while sensorineural was commoner among the controls 57(60.0%). The mean pure tone average among the inmates was 25.6±11.3dBHL and 26.1±11.2dBHL on the right and left ears respectively while in the control group, it was 18.4±7.8dBHL on the right and 17.9±7.9dBHL on the left. Conclusion: This study revealed that hearing loss was more prevalent among prison inmates than the general population. In majority of the inmates, the hearing loss was mild, conductive and mostly affecting all the frequencies.

Background: Presbycusis is related to degenerative changes of aging resulting from deficient cochlear microcirculation. It is characterized by bilateral, symmetrical, sensorineural hearing loss (SNHL) in which recruitment and speech discrimination is affected in the absence of noise exposure. The objective of this study was to analyze the pure tone audiogram characteristics in Presbycusis. Methods: This descriptive study recruited n=192 cases of presbycusis of both genders, aged 50 to 80 years with convenience sampling technique. The study was conducted at Yusra General Hospital and the National Institute of Rehabilitation Medicine, Islamabad from1st July 2017 to 30th September 2017. Pure tone audiometry was used to collect audiometric data. SPSS-24 was used for data analysis. Chi-square and Pearson’s correlation were used to determine association between variables with p < 0.05 taken as significant. Results: Pure tone audiometry revealed 58 (30.2%) right and 65 (33.9%) left ears with high frequency gently sloping audiogram, while the second commonest configuration being high frequency steeply sloping curve in 51(26.6%) right and 52(27.1%) left ears. There was a significant correlation between the configuration of the audiogram and age with p=0.000, while no significant correlation with gender (p=0.71). The majority,77 (40.10%) right and 71(36.98%) of left ears had moderately severe hearing loss, while severe hearing loss was second commonest with 60(31.25%) right and 70(36.46%) left ears affected. The severity of hearing loss had a significant (P=0.000) positive correlation with age but no significant relationship with gender. Conclusion:  High frequency gently sloping audiogram was the commonest configuration followed by high frequency steeply sloping curve. Moderately severe hearing loss was most commonly seen followed by severe hearing loss.

Purpose The aim of this study was to assess the proportion of patients seen in a tinnitus and hyperacusis therapy clinic for whom presentation levels based on the British Society of Audiology (BSA)–recommended procedures for pure-tone audiometry and determination of uncomfortable loudness levels (ULLs) exceed ULLs, leading to discomfort during administration of these procedures. Method This was a retrospective cross-sectional study of 362 consecutive patients who attended a National Health Service audiology clinic for tinnitus and/or hyperacusis rehabilitation. Results For 21% of the patients, presentation levels based on the BSA procedure for pure-tone audiometry exceeded the ULL for at least 1 of the measured frequencies (excluding the first frequency tested, 1 kHz): 0.25, 0.5, 2, 3, 4, 6, and 8 kHz. For 24% of patients, the starting presentation level of 60 dB hearing level recommended for determination of ULLs exceeded the ULL for at least 1 frequency. Conclusion The starting presentation levels used for pure-tone audiometry and measurement of ULLs should be lower than those recommended by the BSA for people with tinnitus and hyperacusis.
