| 摘 要： | 采用声电类比的传递矩阵法，本文对消声器插入损失进行了理论探讨，所推导的理论公式准确地反映了整个内燃机排气系统对消声器插入损失的影响，克服了其它学者在研究此问题中的不足，考虑了声源声阻抗对传递损失的影响，对消声器的整体优化设计具有重要的指导意义。 |

| Abstract: | In the method of electroacoustic transfer matrix, the muffler insertion loss was studied in this paper, the relationship between the structure parameters of internal--combustion engine exhaust system and its insertion loss was given by the formulas, the disadvantages were overcome and the acoustics source impedance influence to insertion loss was thought of. All of these works are helpful to the muffler optimum design. |
| Keywords: | Muffler Transfer matrix Acoustics impedance Insertion loss |
