Electrical Generators Noise Effect at The Hearing Threshold on Workers

Abstract

Sound level meter was used to assess the noise levels produced by electric generators. The average noise level of 15 generators was measured, and it was found to be greater than the daily exposure limit of 101.5333 decibels. It was also investigated how this kind of noise affected workers' health, particularly in terms of hearing loss. The study involved 51 workers who underwent a pure tone average (PTA) test to assess their hearing level after otoscopic examination. After statistical analysis of the data, it was found that 42 workers had hearing loss in the high frequencies (left and right ear) and 30 and 38 workers had hearing loss in the speech frequencies in the right and left ear respectively. The study also covered the connection between aging and hearing loss.
