Experimental research on the characteristics of the noise source of the Chinese high-speed railway

Abstract

Being familiar with the level and characteristics of a high-speed railway’s noise sources is the theoretical foundation for better noise control. Based on a large number of field experiments relating to Chinese high-speed railway noise sources, the work described in this paper assessed the characteristics of the noise sources at bridge sections and embankment sections in the speed range of 200–300 km/h and 300–350 km/h separately. The paper discusses the relationship between the noise production and the train speed. In the end, the comparison of high-speed railway noise source levels in China and those in foreign countries like France and Germany showed that the noise source levels in these countries were almost the same.
