Measurement and analysis of noise pollution in Al-shaheed Copper and Brass factories, Iraq.

Industry workers suffer psychological and physical stress as well as hearing loss due to industrial noise. Although noise source control can be profound process sometimes, it would be the most effective way to eliminate noise level on source. Therefore, identifying dominant source of noise shall be the first step to overcome the noise problem in industry. This paper presents the noise pollution in Al-shaheed Copper and Brass factories in Iraq at 33°06ˉ04˭ longitude and 43°48ˉ50˭ altitude. The factories are staffed by 1700 workers for 12 hours a day, 7 days a week. This study depended on the maximum permissible occupational noise exposure limit of International Standards Organization (ISO) and Occupational Safety Health Act (OSHA) as a comparison reference. And proved that the half of the work sites in factories where unacceptable noise levels and all sites of comfort workers exceeded the limit of acceptable noise and the study also proved that the administration building factories sites within the levels of the noise surveys and administrative staff in safety from the impact of noise in factories. Also the Noise pollution has no effect on residential areas near the factories.
