Acoustic Property Prediction of an Automobile Air Filter with Acoustical BEM
In this paper, we use Acoustical BEM to predict the muffling effect of an air filter improvement with Helmholtz resonator of a domestic commercial vehicle. The result shows that the method works at some frequency range, which means there is a peak value of transmission loss close to the wanted frequency. And the position of the Helmholtz resonator is optimized.
