| Abstract: | In this paper the general equations and boundary condition are derived for the perforated tube elements used in the exhaust silencer of internal combustion engine. With the aid of numerical computation the transmission matrices for the perforated tube elements are set up. Their transmission losses are calculated, and their silencing of noise properties analyzed. This calculation method put forward by the authors provides a practical basis for the design of the silencer. |
