摘要
阐述了四端子网络法在抗性消声器设计中的应用,介绍了消声单元的传递矩阵,并由此导出了消声器插入损失的计算公式,可对所设计的消声器的消声性能进行计算与预测.
The use of transmission matrix in the design of reactive muffler is discussed in this paper, thenbased on the transmission matrix of the noise elimination cell, the insertion loss formula of the muffler is deduced. It can be used to calculate and forecast the muffler＇s noise elimination capability. This appears to be useful for the design and further study on mufflers.
