3D sound scattering by rigid barriers in the vicinity of tall buildings

摘要

The boundary element method (BEM) is used to evaluate the acoustic scattering of a three- dimensional (3D) sound source by an infinitely long rigid barrier in the vicinity of tall buildings, The barrier is assumed to be non-absorbing and the buildings are modeled as an infinite barrier The calculations are performed in the frequency domain and time signatures are obtained by Means of inverse Fourier transforms.
