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