Outline of Final Research Achievements

This paper presents an advanced road traffic noise evaluation system using virtual reality technology based on the immersive projection technology. The key feature of the system is that the road traffic noise is provided for users by both auditory and visual information under various road and vehicle conditions. The geometric acoustic theory and the acoustic wave theory are employed for the simulation of traffic noise. The visual information of road traffic noise is created by the visualization system based on the Open-GL and CAVE library and the auditory information is created by the Max/msp. In order to investigate the effect of traffic noise to the psychological influence of a human being, the measurement of brain wave is performed.
