In ISO-9000 and 14000 management , Health of employee and employers is very important. Noise is a very important agent that was caused to decrease productivity in mines, The worker was contacted with noise, Noise in mines was caused to decrease the level of worker health and
productivity . This study was done to determine the level of noise pollution in mines of Harsin region in Kermanshah in 1380.Method: This study was done at during the first half year in 1380. The method of this study was conformed with Niosh and ACGIH method. Noise was measured in a weighting Net work in fast response. The noise was analyzed in Octave band between 125-8000 HZ in the step of study was used sound level meter Quest- 2800 and Quest -2900. In second step of this study, was measured Leq factor and Noise Dose. For comparing results with standards was used Z statistical method. Results: The results of this study was showed that the drilling worker and Knapping - hammer
worker was contacted with 108.4Plus-Minus 3.4 dB. The noise Dose in this worker was 97.3 Plus-Minus 2.1 dB . The level of Noise was high in 2000-4000 HZ, The results at transport in the mines was showed that the level of noise was 95.3 V 1.7 dB and the Noise Dose was 90.4 V 2.6 . The level of Noise in 1000-4000 Hz was high. Discussion: Noise pollution in the mines was much higher than standards (90dB). The best earmuff is blue comfort. For using in this mines.
