Abstract

Audiograms from 49711 workers exposed to industrial noise over 85 dB(A) and with no obvious ear pathology were analyzed by sex and age. It was found that the configuration of the mean audiograms shows a notch at 6 kHz instead of 4 kHz reported in previous studies. When the mean audiograms were corrected for presbycusis, the notch shifted from 6 kHz to 4 kHz only for the age groups over 45 years. The reasons for the difference between results of previous studies and this study are discussed
