Abstract
This paper presents a simulation method based on the wave-acoustic theory and its application to the auralization of traffic noise. The CIP method using adaptive mesh refinement (AMR) is employed for solving the governing equation accurately. In order to obtain the accurate numerical solution by CIP method for the propagation of an impulse wave, an imitation impulse developed by Lubich is employed. The auralization of traffic noise is performed by the convolution using the results and the sound source data. The present method is applied to three-dimensional wave propagation problems in order to investigate the validity of the method. The present method is shown to be an useful tool to investigate the traffic noise.
