Abstract

An analysis of the noise sources in coal mines and the noise control design of truck mufflers was discussed. The acoustic noise measurement and modeling of the sound propagation in mines was performed. The factors taken into account included topographical features, vegetation, wind direction. The noise measurements indicated that the engine exhaust was the most significant noise source and a muffler was designed for providing the requried noise attenuation.
