| Abstract: | Acoustical property of cross-flow muffler is investigated based on sound propagation theory in this paper. The transmission matrix is deduced by establishing equivalent model and dividing the perforated pipe to finite elements. And the accuracy of this method is testified by contrasting it with experiment data. |
