Abstract This study investigated the effect of occupational exposure to noise and organic solvents on hearing loss among aircraft maintenance workers. The study population comprised 542 male workers for whom exposure and medical examination data were available. The prevalence of hearing loss found in the group exposed to noise and mixed solvents simultaneously (54.9%) was higher than those in the other groups (6.0% in the unexposed, 17.1% in the noise-only exposed, and 27.8% in the solvents-only exposed). The relative risks, adjusted for age, were estimated to be 4.3 for the noise-only group, 8.1 for the noise and solvents group, and 2.6 for the solvents-only group. These findings suggest that chronic exposure to mixed solvents had a toxic effect on the auditory system. This raises the issue of whether hearing conservation regulations should be applied to all workers exposed to solvents.
