Car Cabin Acoustics — Transient Analysis
Application ID: 132741
This tutorial shows the analysis of a car cabin in order to study the performance of a sound system in the low to mid frequency range. The model studies the transient response to an emitted Gaussian modulated harmonic signal solved with thePressure Acoustics, Time Explicitphysics interface.
Frequency dependent impedance conditions for the seats, carpet, and roof are included using theGeneral local reacting (rational approximation)impedance option. The input data is fitted using thePartial Fraction Fit. The model is solved using the Accelerated solver formulation that can be run on a GPU.
