DEVELOPMENT OF MIXED TRAFFIC NOISE EVALUATION SYSTEM USING VR AND ACOUSTIC SPATIALIZATION TECHNOLOGY

Abstract

This paper presents a road-traffic noise evaluation system using virtual reality technology. In order to provide an experiencing person with a virtual world with so much presence, the 3-D acoustic spatialization using Ambisonics techniques is employed. A complex acoustic field under mixed traffic is reconstructed in VR space. Therefore, it is able to understand and assess traffic noise intuitively, around various environments such as building complex, tunnels, elevated structures and so on. This system is applied to several examples in order to investigate the validity of the method.
