Background: The cause of most industrial accidents can be found in not observing the consideration of engineering science completely and human factors at individual or organizational levels. Undesirable noises in working areas, has negative effects on workers’ mental conditions and reduces their pruductivity. Based on these facts, the subject of assessing the noise pollution rate in industrial environments & presenting practical approaches for improving and controlling work conditions was reviewed & implemented in one case study. Material and Methods: For recognizing and assessing the pollution rate in different working stations, noise elevations at different levels were measured by SLM machine and the average pressure elevation of the considered unit noise was calculated. In addition, noise dosage was performed for the employed personnel and the maximum permitted time for working units was measured. To assess the effects of undesirable noises on the employees, the hearing level of all the under-study personnel was reviewed by periodical tests. Results: Input analysis showed server noise pollution in the area of word chips production and the results of measuring noise reduction hearing level of the personnel was an indication of noise pollution in the above mentioned area. After applying the related approaches, the results of periodical noise measurements for the personnel showed that noise pollution of that area was under control. Conclusion: Following the individuals and managerial actions for solving the problem of noise pollution in the wood chips area, the continuous reviews and noise measurement tests, showed that the undesirable effects of the noise on the personnel was under control.

Keywords: noise pollution, reduction hearing level, dosimetring, periodical noise measurements
