Abstract: Sound of exhaust system makes a substantial contribution to the interior as well as exterior noise of automobiles. Accurate prediction and control of noise from automobiles is of significant importance in automotive exhaust system design. When it comes into the term of acoustic performance there are several parameters that describe the performance of a muffler, the Transmission Loss (TL) being the most popular one for validating an analytical model. Acoustic characteristics of silencers filled with fibrous material are also studied.
Keywords: Transmission Loss (TL), Reactive Muffler, Central Inlet and Side Outlet, Multi Expansion Chamber, Dissipative Muffler, Hybrid Muffler, Sound Quality.
