A Study on the Vertical SPL of Railway Noise by Noise Barrier

With rapidly industrial development, a railway has become of a main traffic means. But, the railway noise has caused much annoyance for the residents living nearby railway tracks. Therefore, in our country, for established of quite dwelling environment. execute regulation standard of railway noise from January 1. 2000. Efficiency soundproofing measures, however, are very difficult because of the lack of basic data and insufficiency of the existing research. In this point. this study attempts to survey the vertical sound pressure level of railway noise in by existence of noise harrier And this study intends to get the basic data for establishment of a efficient noise barrier about railway noise.
