【Abstract】 The use of transmission matrix in the design of reactive muffler is discussed in this paper,then based 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.更多还原
