Abstract

Plane wave propagation can be assumed in many duct and exhaust systems because the dimensions of the silencer and muffler components are small compared to an acoustic wavelength. However, the plane wave assumption is not appropriate for larger duct or exhaust systems. Examples include HVAC duct systems, and large diesel engine mufflers commonly used in ship and generator sets. In this paper, the finite element method is utilized to simulate large duct systems and then to predict the insertion loss. The boundary condition at the source is a diffuse field applied using the diffuse reciprocity relationship developed by Shorter and Langley. Simulation results are compared to published measurement results for HVAC plena and show excellent agreement.
