Abstract


For the over exploitation of cities, it makes that tall buildings and cloverleaf junctions are full of the city above the land, which breach the nature environment, also brings problems in the common traffic on the city land. So, underground is invented when the cities are big enough. Up to the end of the 20th centuries, there are 115 cities with underground, and the total length of the underground is over 7000 km. The subway stations are the most important thing of the underground, and the Sound Environment Design is attached important.At the present time, it is fastigium in underground-building in China, but the Sound Environment Design is just at the beginning. The article is focused on the subway stations in China, by the experimentations of the non-diffuse sound field and the sound theories in long-room, with the locale research of subway stations, concludes the problem of the Sound Environment Design in the subway stations in China, and gives measures correspond to the problems.Firstly, the article reviews the theories of the tradition acoustics, expatiates that the theories of the tradition acoustics are unsuitable with the long- room. By the summarization and analyzing of the sound experimentation results, concludes the problems of the Sound Environment Design.Secondly, based on the locale research of subway stations, this paper concludes the main style and room modalities in China, and by analyzing of the theories, this paper summarizes the problems of the Sound Environment Design in the subway stations in China.At last, in allusion to the actuality of the subway stations in China, with the results of the sound experimentation results, the article makes some strategies in four sides: the Sound Environment Design in public, the Sound Environment Design in rail sections, the sound insulation in side chapel rooms, and the language-impression index.The article is based on the non-adaptation between classical sound theories and the acoustics of long spaces. By the he locale research of subway stations, concludes new cognitions of the sound index in long-room, and analyzes some problems in the practice according to the data analyzing. In China, the research of sound in the subway stations is just on the way, so the article is meaningful for the improvement of study in the field.
