Abstract

Otoacoustic emission (OAE) testing is not widespread in Japanese industrial health. This study examined the association between hearing thresholds (HTs) and OAEs among workers exposed to noise in actual workplaces. In two metal products manufacturing factories, 34 workers with noise exposure in the workplace (exposure group, mean age 40.6 ± 9.4 years), and 9 workers with no noise exposure (control group, 49.0 ± 14.3 years) were surveyed. The time-weighted average (LAeq) and maximum (LAMAX) of environmental noise monitoring (ENM), and the time-weighted average (LTWA) and sound exposure level (LAE) of personal noise monitoring (PNM) were measured for each subject at the same time. As hearing effect indicators of noise exposure levels, HTs (0.5, 1, 2, 4 and 8 kHz) and distortion product OAEs (DPOAEs) (2, 3 and 4 kHz) were performed before and after 5 days of work. The results of the ENM, PNM, HTs and OAEs were compared between the groups using Student's t test, and their correlations were investigated using Pearson correlation coefficients. Noise exposure levels of the exposure group were significantly higher than those of the control group. In the exposure group, LAeq, LAMAX, LTWA and LAE were respectively 84.5 ± 4.1 dB(A),89.5 ±...Continue Reading
