| Summary: | In the past few decades, a rapid of industrialization increasing the noise pollution and provides a people awareness to combat this issue. Here, apart from providing employment opportunities to worker, manufacturing industry also produce disturbing noise that is generated by various sources especially from the machineries. The aim of this study is to estimate the maximum working hours due to the over exposure of the noise hazard in the industry. Initially, the reading of noise exposure was obtained using the dosimeter. Then, criteria for a recommended standard occupation noise exposure based on NIOSH (1998) and OSHA (1989) noise working safe condition was measured. The results indicate that there is high risk of noise-induced hearing loss (NIHL) among workers that come from the noise exposure was obtained. The critical is CAM & CNC department with less than 0.125 hours and 1.33 hours following NIOSH and OSHA regulation respectively. In addition, the proposedly related noise exposure working period are also included.
