105 生活・住環境における音の評価と現状 : 日本人とタイ人の音環境のとらえ方

Abstract

I had been transferred to Environmental Research and Training Center (ERTC) of Thailand from 1999 of March to 2001 of February, to transfer the environment noise technologies as JICA Expert. This paper reports on the present state of Noise Environment in Thailand I survey during this period. The contents of this paper consists of 1) The present state of Noise Environment in Thai, 2) The traffic system and Traffic noise condition, 3) Environmental Noise condition in Thai city, 4) Thai views on this traffic noise condition. The city noise in Thailand is almost the traffic noises, which are almost the internal engine exhaust noise of 1) Motorcycle, 2) Tuk Tuk (three wheels Thai-car), 3) Bus, Truck etc. of old model and 4) Long tail boat on the rive and canal. And the reasons that the traffic noise in big city, for example Bangkok is bigger are : 1) Economical condition, 2) Don't be used the adaptive exhaust silencer by technical misunderstand, 3) Thai citizen ls lack of interest for traffic noise, 4) Can't control traffic noise by law. Traffic noise problems occur not only in big cities of Thailand but also in big cities of Southeast Asia by same reasons. My conclusion is that the policy of Japanese economy and the policy of Japanese manufacturers as supplier of vehicles are deeply concerned in the traffic noise problems of Southeast Asia and we have to discuss and resolve traffic noise problems in Southeast Asia as our problems.
