Abstract
The audiometric examinations of motor-sawers exposed to intermittent noise at a level of 98-112 dB (A) for 1-4 hrs daily indicated hearing losses. An index of the potential hearing impairment risk induced by noise is a temporary hearing threshold shift due to that noise exposure. The studies showed not a single temporary hearing threshold shift in motor-sawers after a daily exposure to the saw noise, which implies that the noise does not immediately affect the hearing organ.
