| Abstract: | Sound muffling mechanism widely applied to ceramic beehive carrier currently for motor vehicle exhaust emission purification muffler are analysed and its acoustic transmitting matrix is give out basedon the theory of multi-hole acoustic absorbtive material of theory of acoustic transmitting matrix, and severalprincipal factors which affect property are also analysed. Simulating computation of sound transmitting losshas been carried out, of which the result is practically the same as that by substantial measurement. |
