Abstract
This paper presents a numerical simulation method for transient acoustic field analysis based on boundary element method and its application to the auralization of road traffic noise. For the governing equation, the unsteady wave equation is employed. In order to solve a large scale problem, the fast multipole boundary element method (FMM) is applied. Three dimensional wave scattering problem with a road trafic noise is solved by the time domain FM-BEM. The auralization is investigated by using the computed sound pressure.
