Title

Systematic Procedure for the Analysis of Multiply Branched Acoustic Transmission Lines

Abstract

The transmission of relatively low-frequency sound in piping systems is an important problem in a variety of applications. Of particular interest in this investigation are exhaust and induction systems for internal combustion engines. Both of these examples involve manifolds, expansion chambers, cavities, and complex piping arrangements. They can be described as multiply branched acoustic transmission lines. They have the common feature that the wavelengths of the propagated sound are large compared to the transverse dimensions of the system components, except perhaps in elements such as expansion chambers or plenums at the highest frequencies. Other applications include fluid transmission lines and compressor discharge lines.
