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

Abstract 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

フウドセイ ト デザイン : トウトウミ ノ バアイ

本研究は、起業精神、先取り精神で多くの製造業(トヨタ、ホンダ、スズキ、ヤマハ、河合楽器、浜松ホトニクスなど)の創業者を輩出し、地方都市でありながら世界レベルの技術が集積し、それを形にする高いデザイン力を備えているモノづくりの街、浜松における文化のあり方としてのデザインを考察したものである。This research, based on climate milieu and design, considers the design as the state of culture in Hamamatsu area where many manufacturing enterprises have been founded. This area has produced a large number of founders, of those enterprises, such as HONDA, SUZUKI, YAMAHA, KAWAI and HAMAMATSU PHOTONICS. Although it is a local city, the technology of a world level is accumulated, and the design as the state of the culture in the town of manufacturing is equipped with the high design power
