Abstract

Objective:To know the effect of noise on hearing loss of workers.Methods:500 workers exposed to noise were selected to do labour health investigation,meanwhile 500 workers were selected to be control, Differences in the level of hearing loss were analyzed.Results:The results showed that the hearing loss incidences in noise group and control group were 22.4% and 4.2% respectively. It was significantly difference (P0.01);The incidence was relatived with the working age and the level exposed to noise.Conclusions:Accompanying the increase of noise intensity exposure and the length of employment,the hearing loss was increased correspondendtly .
