Open publisher page 0 citations

Abstract

The paper shows the measurement of the sound transmission loss of elliptical chamber muffler having different ovality parameters. 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. A silencer is an important noise control element for reduction of 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).
