ABSTRACT
Indusrial noise exposure is the most common hazardous agent in the world.This study has been done to determine the prevalence associated with occupational noise in car smoothers at Qazvin. The study group composed of 50 subjects who were selected out of a total of 218 car smoothing workshops.Background information,exposure time and ... with a questionnaire collected.Noise exposure and hearing loss were measured by noise dosimeter model CEL-280 and audiometer model OB 288 Madsen. The mean of age and work experience were 38.7 and 21.5 respectively.Noise exposure and total hearing loss were measured 98.2 +/- 3.4 dB [90-104dB] and 22.1 +/- 9.16 dB respectively. Spireman correlation was significant between right and left ears [P<0.05, R=0.87].Total hearing loss were measured natural [NIHL
