Abstract

In this paper, the acoustic performance of a simple Expansion chamber Muffler for center inlet-center outlet and center inlet-side outlet is analyzed. Muffler is the most common device used for suppression of sound. Transmission loss (TL) of a Central inlet – Side outlet muffler is predicted by Transfer Matrix method for different positions of outlet. TL for both muffler configurations having different outlet position with same volume has been analyzed. The influence of different side outlet positions of the simple expansion chamber muffler on its acoustic performance was studied. In this paper, the principles of TMM for calculating the transmission loss (TL) of a muffler are used. Finally it is shown that by adopting suitable design of the muffler it is possible to improve acoustic performance of muffler.
