摘　　要：推出具有多个内插管并联管路声学元件的声传递矩阵 ,利用声传递矩阵进行柴油机排气消声器的插入损失的计算 ,模拟计算结果与试验数据具有较好的拟合程度 .The transmission matrix of the multi insert pipe parallel structure was established. The insertion loss of a diesel engine muffler was calculated by the method of acoustic transmission matrix. The result showed that the calculated insertion loss was roughly conformed to the measured one.
