“…There have been only a few studies: a report of progressive hearing loss in workers exposed to carbon disulfide (38); a study on correlation between blood lead level and hearing impairment for investigating hearing impairment from lead exposure (39); a study on the effect of exposure to mixed organic solvents on hearing in video tape manufacturing workers (40); a study on the effect of exposure to organic solvents on occupational hearing loss in noise exposure group and group concomitantly exposed to noise and organic solvents in metal products manufacturing company workers (41); and a study comparing the hearing loss by category according to characteristics of exposure to noise and chemicals such as heavy metals and organic solvents (42). Mean hearing threshold was higher in the mixed organic solvent-exposed group than in the non-exposed group, and hearing threshold was higher in the subgroup with simultaneous exposure to organic solvent and noise than in the noise-exposed group at frequencies higher than 4,000 Hz.…”

In this article, current status of noise exposure in workplaces, trend of workers with noise-induced hearing loss (NIHL), and prevalence of NIHL in workers by industry and job category in Korea were reviewed. In addition, trends of research on the audiological effects such as hearing loss from noise and occupational hearing loss from non-noise in Korea were addressed through reports in industrial audiology. Though noise exposure level has improved, noise still shows the highest rate of cases exceeding exposure limit among workplace hazards. NIHL is the most common occupational disease except work-related disease such as musculoskeletal disorders and cerebrovascular diseases, and NIHL prevalence is thought to be much higher than reported in official publications. Noise affecting hearing comes from various sources such as workplaces, military settings, areas with exposure to high noise, and specific noise sources. There is also occupational hearing loss by non-noise including chemicals such as organic solvents and heavy metals, barotrauma, and trauma due to welding spark. Noise affects daily life through audiological effects such as hearing loss and tinnitus, non-audiological physical effects (e.g., cardiovascular), and psychosocial and behavioral effects. Development of systematic and comprehensive hearing conservation programs for lowering the noise level in workplaces and preventing the NIHL, and preparation of technological, administrative system for its settlement at workplace are urgently needed.
