Abstract

Background: Driving is a usual job with many occupational complications. Occupational hearing loss in track driver is not an unusual occupational problem. We studied the relation of occupational hearing loss and long term noise exposure in track drivers.Methods: This descriptive study was done among track driver population in Kashani and Al-Zahra hospitals in Isfahan. Taking medical history and physical examination were done by an expert otolarygologist and then, eudiometry was done. The data were analyzed by paired-t and variance regression tests via SPSS11.5 software.Finding: In 384 track drivers, hearing threshold in left ear was more than hearing threshold in right ear (P < 0.001).Conclusions: In this study, such as the other studies, a relation between persistent noise and hearing loss was observed. In track drivers, persistent noise can cause occupational hearing loss and their left ears are more susceptible than the rights in risk.
