Résumé

Abstract Background Globally, the prevalence of occupational noise-induced hearing loss ranges from 16–24%. Moreover, occupational noise exposure is a major public health problem among metal and woodwork workers in sub-Saharan Africa including Ethiopia. However, there is limited evidence about the risk of hearing impairments and level of noise exposure in Ethiopia. Methods In this cross-sectional study 580 metal and woodwork employees in Gondar town were surveyed from February10-March 25/2020. The data were collected through an interviewer-administered questioner and the noise exposure level was measured using an ICE 651 type II sound pressure level meter. The data were entered into EPI info version7 and analyzed using SPSS20 version software. Bivariable and multivariable logistic regression analyses were performed to identify factors associated with hearing impairments. Result The overall prevalence of self-reported hearing impairment was 20.7% [95%CI: (17.4–24)]. From the total participants, 11.2% of the woodwork and 9.5% of metal workers reported hearing impairments. The mean (± SD) noise exposure level in both industries was 96.63 ± 3.7 dBA. Listening to music using earphones for more than two hours per day [AOR = 5.33, 95% CI (1.29, 21.9)] and playing music with loud volume (AOR = 3.75 (1.13, 12.43) were significant risk factors for hearing impairments. Conclusion The prevalence of hearing impairment is comparable in metal and woodwork worker, but higher noise exposure level is recorded in woodwork industry and the majority of the employees exposed to the noise level above the permissible exposure limit. Therefore, the hearing conservation program shall be implemented in both wood and metalwork industries.
