In order to identify the performance of simple expansion chamber with/without offset and currently using muffler of the 1.51 engine class passenger vehicle(H-muffler). experiments using the two michrophone method were carried out. Transmission loss of silencer with elliptic cross-section type was calculated by Sysnoise, a general purpose acoustic software, and was compared with that of various sizes of circular cross-section type silencers. In this paper, sound pressure level and transmission loss of simple expansion chamber with/without offset and H-muffler were measured.
