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.

Abstract Background Noise-induced hearing loss (NIHL) is often characterized by the presence of an audiometric notch at 3000-6000 Hz in a behavioral audiogram. The audiometric notch is widely used to investigate NIHL in children and young adults. However, the determinants of the audiometric notch in young adults largely remain unknown. Purpose The study aimed to investigate the determinants of the audiometric notch in young adults. Research Design A cross-sectional design was adopted for the study. Study Sample A sample of 124 adults (38 males and 86 females) aged 18-35 years with normal otoscopic and tympanometric findings was recruited. Data Collection and Analysis Hearing thresholds and real-ear sound pressure levels (RESPLs) were obtained with calibrated ER-3A (Etymotic Research, Elk Grove Village, IL) andTDH-50P receivers (Telephonics, Farmingdale, NY). Distortion-product otoacoustic emissions (DPOAEs) were used to evaluate the cochlear function. The external auditory canal (EAC) length was measured using the acoustical method. Noise exposure background (NEB) was estimated using the Noise Exposure Questionnaire. The notched audiograms were identified using: Phillips, Coles, and Niskar criteria. Results The prevalence of notched audiograms was substantially higher for TDH-50P supra-aural receivers than for ER-3A insert receivers. RESPLs at 6000 and 8000 Hz were the major predictors of notched audiograms for TDH-50P receivers. These predictors explained around 45% of the variance in the notched audiograms. The notched audiograms obtained with TDH-50P receivers showed no association with NEB. Individuals with notched audiograms measured using TDH-50P did not show convincing evidence of cochlear dysfunction as assessed by DPOAEs. Individuals with notched audiograms obtained with TDH-50P receivers revealed an average of shorter EAC and a poorer hearing threshold at 6000 Hz. Conclusions The calibration error in the RESPLs at 6000 and 8000 Hz that are likely to be influenced by the shorter EAC was the major determinant of the notched audiograms when the supra-aural transducers were used to measure hearing thresholds. Therefore, the supra-aural receivers should not be used to estimate the prevalence of NIHL in children and young adults when the less restrictive notch identification criteria are used to identify NIHL. Real-ear calibration techniques that are least influenced by the standing waves in the EAC should be preferred when investigating the prevalence of and risk factors for NIHL in young adults.

ObjectiveThis study investigated risk factors for poor earplug fit, with a focus on the association between hearing loss and personal attenuation ratings (PARs).MethodsEarplug fit was assessed by obtaining PARs using a real ear at attenuation threshold (REAT) system. Hearing loss was assessed using the unoccluded hearing thresholds measured during the REAT testing and the results of a speech-in-noise test. Potential predictors of PARs were modelled using both simple and multiple linear regression. Hearing loss was the primary predictor of interest.ResultsData were collected from 200 workers at ten above-ground mining sites in the Midwestern USA. Workers reported wearing their hearing protection on average 73.9% of the time in a high noise environment (mean 8-hour time-weighted average noise exposure 85.5 dBA, range 65–103 dBA). One-quarter (26.7%) of workers were found to have a hearing loss (hearing threshold ≥25 dB across 1–4 kHz), and 42% reported symptoms of tinnitus. Workers with a hearing loss had a significantly lower PAR than those without a hearing loss (β=−5.1, SE=1.7).ConclusionsThe results of the adjusted regression models suggest that workers with hearing loss achieved significantly lower PARs than those without hearing loss. This association between hearing loss and hearing protection devices (HPD) fit brings into focus the potential benefit of fit checks to be included in hearing conservation programmes. Workers found to have hearing loss should be prioritised for fit testing, as their hearing impairment may be associated with poor HPD fit.

Introduction: Noise Induced Hearing Loss (NIHL) is an occupational health hazard linked with noise exposure of more than 85 dB. Aircraft noise and other occupational noise exposure cause military aviators more susceptible to NIHL than commercial jet pilots. Aim: To find out the prevalence of noise induced hearing loss among different military aircrew population with special emphasis on identifying the associated risk factors. Materials and Methods: This cross sectional study was conducted on Kuwait Air force pilots those who came for annual medical checkup from July 2010 to July 2012. Audiometry of all subjects was done by ENT specialist and necessary data were collected by structured questionnaires. All data were analyzed by SPSS (Statistical Package for the Social Sciences) version 17.0 Results: Out of 221 aircrew 32 (14.48%) developed NIHL. Hearing loss was mild to moderate and predominately at high frequencies. Most affected group was helicopter pilots. Pilots of more than 40 years of age and those who had more than 1000 flying hours had mean hearing threshold more than other groups. The right ear was affected in majority of cases than left ear. Conclusion: Noise exposure to aircrew is inevitable so hearing loss prevention strategies might play a pivotal role to save aircrew hearing. Active surveillance of hearing protection practices might have beneficiary effect. Steps can be taken for early detection of NIHL and hearing conservation program.
