Abstract

Identification of the dominant source could provide instructive guidance for noise mitigation. In this paper, the relation between aerodynamic noise and rolling noise was quantitatively analyzed based on the characteristics of high speed train's pass-by noise. The results indicate that at the speed of 300 km/h, rolling noise is 5.2dB higher than aerodynamic noise, and aerodynamic noise becomes predominant as the speed increasing to 380 km/h.
