摘要
以消声器声传递矩阵分析方法为基础，给出了５种内燃机抗性消声器声学子结构的声传递矩阵，编制了消声器性能分析的计算机程序，计算了两种结构的消声器插入损失并进行了试验，结果表明，计算值与实测值吻合良好。
Basedon theanalysis method of the sound transfer matrices，5kinds of thesound transfer matrices of sound substructures of the restricting type exhaust mufflers ofinternal computer programs about characteristic analysis were worked out．The sound in-sertion loss of 2 kinds of muffler structures were calculated， and the calculation wasvalidated by the experiments．The results show that calculated values and measured valuescoincide well.
