Level of Sound in a Power Plant Generated by Natural Gas: A Case Study of Its Mapping

Abstract

          The Noise Pollution and Abatement Act of 1972 is a statute of the United States initiating a federal program of regulating noise pollution with the intent of protecting human health and minimizing annoyance of noise to the general public. According to view of Environment Conservation Rules, 1997, the DOE Bangladesh the perfect sound condition for Bangladesh is 75 dB for the day time and 70 dB for the night in industrial areas. Regent Energy Power limited (REPL) 106 MW power plant and 38 natural gas generated machines and 68 exhaust fans. The level of sound was produced by generators and exhaust fans of REPL. The aim of the study will be mapping of sound around the REPL. According to sound mapping the sound level was somewhat greater than standard level (75 dB) of day time. OSHA has been shown 3 dB decreased by one meter distance from its origin, but 0.44 dB decreased by one meter distance from its origin in around REPL.
