Abstract
The transfer matrix analysis of the transmission through walls as discussed in Chap. 3 is readily adaptable to the analysis of mufflers. This approach will enable us to construct models of muffler and/or duct systems having nearly arbitrary complexity. In the following, we will examine several key muffler components using transfer matrices. A very common muffler construction is the expansion muffler, which consists of a section of a pipe or duct that has an increased cross-sectional area. To develop a transfer matrix model of this we will use three transfer matrices, one for each of the junctions at the ends of the muffler and one for the section between each junction.
