Student in Environmental Science, Faculty of Science and Research, Islamic Azad University, Tehran, Iran Journal Article 2015 07 14 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. https://jpoll.ut.ac.ir/article_57876_9a71856c84dab19ca9f753a4216cd2d2.pdf
