采用局部和扩展反应近似的多孔吸声体时域建模

Application ID: 132441


This tutorial studies the propagation of sound in the presence of a porous absorber in the time domain. It demonstrates how to model a porous absorber using the local and extended reacting approximations and compares the two approaches for absorbers of various thickness. The dissipative and resonant behavior of the absorber is frequency-dependent. The use of the Partial Fraction Fit functionality makes it possible to account for the frequency dependency in the time-domain simulations.
