Introduction: Noise is a type of energy when exceeds T.L.V., It can cause hearing loss, especially in working environments. As factory workers are at high risk of noise, the present study evaluated the Bistoon Tile Factory workers hearing losses.
Methods and Materials: In this analytical cross-sectional study, workers’ noise Leq were calculated according to I.S.O. standards and their audiometry results were derived from their health files. Data was analyzed by statistical tables and chisquare test by SPSS 21.
Results: There is no statistically significant relation between age and work history and hearing status of the workers, but a significant statistical relationship existed between noise Leq exposure and audiometry status. The persons with more noise exposure than standard values had bad audiometry status.
Conclusions: Large body of research has indicated that noise has effect on audio system, and in the present study, however the workers age and work history were not long enough to detect an exposure to Leq of higher than the standard level, a high exposure to loud noise reminded us that considering the issue, workers would prove important in the context of occupational health.
