A ROAD TRAFFIC NOISE SIMULATION BASED ON STABILIZED TD-FMBEM AND ITS IMPLEMENTATION OF AN AURALIZATION SYSTEM

Abstract

This paper presents a numerical simulation of a road traffic noise based on fast multipole BEM in time domain(TD-FMBEM) and its application to the auralization using VR system. Because this problem is the large scale problem in time domain, the stabilized method is applied to TD-FMBEM. We solved the traffic noise field having a sound barrier and obtained the stabilized sound pressure using the stabilized TD-FMBEM. We also realize the visualization and auralization of the numerically obtained sound data using VR system.
