Comparison between Square and Rectangular Cross Section Muffler to Predict Noise Attenuation with Same Gas Volume

Authors(1) :-Amit Kumar Gupta

The paper shows the measurement of the acoustical transmission loss of square and rectangular cross section expansion chamber muffler with same gas volume. A muffler (silencer) is an important noise control element for reduction of machinery exhaust noises other noise source which involves the flow of gases. Mufflers are typically arranged along the exhaust pipe as the part of the exhaust system of an internal combustion engine to reduce its noise. Here basic term is used for noise attenuation namely transmission loss (TL). An experimental method for muffler’s transmission loss (TL) measurement for central inlet and central outlet muffler shows the validation of result. Finite element analysis tools comsol multiphysics used to validate the results. The wave 1-D used as a simulation tool. This paper is investigating the shape of muffler which is capable to reduce noise level.
