The Initial Research Of The Railway And Road Traffic Noise In City

Railway and road traffic are close to the noise in city, as one of the environment pollution problems in city, Regarded weightily by society more and more.Traffic noise will affect the work and life of people with rapid development of city.But,noise control of railway and road traffic promote the society of development.In this paper, some railway and road noise control data were read. Noise mechanisms of railway and road traffic were summarized in cities. Some railway and road traffic noise were concluded. The noise of main body was the key of noise control. There into, road traffic associated with noise mechanism, for example, main road, quantity of traffic, styles of vehicle, run-speed, status of road, building position in side way, vibration of noise-solicitation and so on. Secondly, some amount of noise assessment, noise limits and standards were particularized in some countries. The situation and influence of railway and road traffic noise were analyzed in some countries and the influence was harmful to the work and life with exceeding standard. The traffic noise measure codes were used. The residence along the line of railway and road was tested and the data was analyzed in Taiyuan, the situation standard of noise was described. Thirdly, the noise control methods of railway and road traffic were combined in domestic and overseas countries now, for example, noise control of main body, city-layout, environment-layout of city, noise barriers, design of architecture and so on. The methods of railway and road traffic were summarized. In the condition of situation of noise, which was the residence along the line of railway and road in Taiyuan, the advice methods of noise control were proposed.In the paper, referenced data was offered, which was the design of noise reduction in the residence along the line of railway and road.
