This study aimed to describe the noise pollution, and to identify the main noise source for providing sound abatement measures in a petrochemical company. In this context, environmental noise was measured and also the main sound sources were identified. Then, a formula has been proposed as an index of noise control priority to select one part of the company as the first priority for controlling noise. The main sound source of the part selected was found by referring to noise maps and contours. The sound source acoustic properties were analyzed and noise control measure suitable for the situation were adopted. The Company was divided into three sections depending on their noise levels including safe area (16.7%), caution area (74.5%) and danger area (8.8%). Compression part of Air plant was found to be the first priority for the adoption of noise abatement measures and Dryer machines were discovered to be the main sound source.
