The transmission matrix of rigid straight pipe with mean flow and linear temperature gradient is established by dividing the tube into N segments and assuming the gas flow speed and temperature to be constant in each segment, and applying the matching conditions on the boundary of adjacent elements. Utilizing the equivalent circuit diagram of the extended inlet/outlet silencer and the theory of rigid straight pipe that has been established, the mathematic model of transfer matrix of the extended inlet/outlet silencer and its insertion loss can be obtained. The numerical results are verified by comparing them with the experimental results. The results demonstrate that the present theory can well predict the insertion loss of extended inlet/outlet silencer which has mean gas flow and linear temperature gradient.
