The influence of a noisy environment on hearing impairment and tinnitus: The hearing outcomes of 50-year-old male Japan ground self-defense force personnel.
Hearing loss is one of the biggest health problems in the world and occupational noise-induced hearing loss is recognized as the most common work-related illness. However, many factors that result in hearing loss make it difficult to define the specific factor that induces noise-induced hearing loss. To access the exact effect of occupational noise exposure on hearing, we conducted a cross-sectional cohort study of the relationship between noise exposure and hearing impairment in 50-year-old male Japanese Self-Defense Force (JSDF) personnel who work in a noisy environment. This population is ideal for the detection of noise-induced hearing impairments due to the homogeneity of genetic and social backgrounds. ⋯ This study provides specific evidence for the relationship between noise exposure and noise-induced hearing impairments.
