Internal combustion engine is a major source of noise pollution. These engines are used for various purposes such as, in power plants, automobiles, locomotives, and in various manufacturing machineries. Noise pollution created by engines becomes a vital concern when used in residential areas or areas where noise creates hazard. Generally, noise level of more than 80 dB is injurious for human being. The main sources of noise in an engine are the exhaust noise and the noise produced due to friction of various parts of the engine. The exhaust noise is the most dominant. To reduce this noise, various kinds of mufflers are usually used. The level of exhaust noise Reduction depends upon the construction and the working procedure of mufflers. The objective of the present study is to investigate acoustic behavior of reactive muffler by FEM and BEM. Validation of the standard procedure for the use of SYSNOISE software. First, the acoustic performance of simple and concentric resonator chamber is explored with FEA. Computational results obtained are compared with the experimental results available in the literature. Once these result shows good agreement with each other than this finite element analysis procedure can be used for performance analysis of muffler with perforated tubes and baffles.
