A Road Traffic Noise Evaluation System Using Virtual Reality

摘要

This paper presents an experienced-based road traffic noise evaluation system using virtual reality technology. This system has two functions; auralization function and visualization function. The auralization function expose users the computed traffic noise by auditory information corresponding to the CG animation of traffic, the visualization function expose users the iso-surface of the road traffic noise level by CG image to understand the spatial distribution on the noise level. Users can change the road environment and vehicle conditions by using the controller interactively in VR space. The effects of road traffic noise to the human sensitivity is investigated by the measurement of the brain waves. The present system is shown to be a useful tool to evaluate the road traffic noise in planning and designing a road environment.
