Abstract:
Occupational noise-induced hearing loss is referred to hearing loss caused by work-related noise exposure and it is estimated that worldwide, 16–24% of hearing impairment is work-related. Occupational noise exposure and related hearing impairment 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.
