利用四端网络方法对穿孔管插入式的抗性消声器进行分析，建立了该消声器的声传递矩阵，编制了相应的计算软件，计算出消声器的消声频率特性，试验证明，消声器声传递矩阵和计算程序是可行的，可以较正确地分析消声器的频率特性的走向趋势。
The four-terminal network method is used to analyze the perforated tube-inserted resistance muffler, and the sound transmission matrix of the muffler is established. The corresponding calculation software is compiled and the muffler frequency characteristics of the muffler are calculated. Experiments show that the muffler acoustic transfer matrix and The calculation procedure is feasible, which can analyze the tendency of the frequency characteristics of the muffler more correctly.
