A Road Traffic Noise Evaluation System Considering A Stereoscopic Sound Field UsingVirtual Reality Technology

This paper presents a road traffic noise evaluation system based on spatialization of sound using virtual reality technology. The key feature of the system is that the road traffic noise is provided for users by both audio and visual information under various road and vehicle conditions. The geometric acoustic theory is employed for the simulation of traffic noise to realize the real-time simulation. In order to improve the reality, the sound source data for the auralization in VR space are generated from the various car driving tests. This system is applied to several examples in order to investigate the validity of the method.
