Abstract

This article introduces the performance evaluation method of automobile´s exhaust muffler and its the size parameter to the noise elimination effect influence. It presents a two chambers impedance compound exhaust muffler designment´s method based on a boundary element method, which focuses on the truck´s diesel engine. Test shows that the truck exhaust muffler has a good effect with insertion loss of 22.7dB, and by the boundary element method we calculate transmission loss under the static condition. Both are consistent.
