Survey and Analysis of Noise Pollution in the Bidboland Gas Refinery

Abstract

We investigated the issue of noise pollution in the Bidboland gas refinery<br />by noise measurement and surveys. The Bidboland gas refinery has several process units.<br />The sound pressure levels were measured at several places, such as units of 200, 300,<br />400, 500, boiler, powerhouse area, cooling towers pumps, and maintenance area, and the<br />corresponding noise maps were produced by using sound plan software. We identified the<br />sources of noise pollution. We first measured the mean A-weighted sound pressure level<br />in each study unit and analyzed the obtained data in Microsoft Excel. The noisiest units<br />were identified and some suggestions were offered to reduce the sound exposure level. It<br />was specifically noted through the surveys that the noise levels detected in all tested<br />industries was much above 80 dBA limit specified by regulations. In lieu, various<br />measures to control the noise pollution were contemplated and discussed.
