摘　　要：采用传递矩阵法,基于MATLAB软件编制程序对原消声器的插入损失进行了预测、分析以及优化,结合实机通过实验验证了优化的效果。实验结果表明,优化后的消声器比原消声器的插入损失提高了1.5dB(A),说明采用传递矩阵法对消声器进行改进设计为一有效的手段。Using the transmission matrix technique,this article predicts,analyzes and optimizes the IL（insertion loss） of the original muffler based on the MATLAB softer.The optimized result has also been validated by experiment.The experiment result shows that the IL of the optimized muffler increased 1.5dB（A） than that of the original one.It indicates that the transmission matrix technique is an efficient mean in optimizing and designing the muffler.
