Abstract

The noise measurement and analysis system of multi-channel was used at a test of high-speed intercity railway coaches analyzing the noise at different operating conditions and different speed, the sound field distribution in the intercity high-speed railway coach was tested and analyzed. The results show that the maximum noise in the car of the same height which is at different positions is at the vestibule diaphragm, followed by the bogie positions at the end portion of the vehicle body, minimizing noise is at the vehicle center position, the noise value at the vestibule diaphragm and the central body was maximum difference 20dB(A); the noise inside the car reflected by the tunnel wall is mainly in the frequency range 630-1000Hz; in the same location of different heights, noise is concentrated in the low and middle frequency band, and in that band noise attenuation is slow, the noise is mainly through the floor and the roof spreading to the car; it is obtained that the noise frequency of the intercity high-speed railway passenger car is mainly concentrated in 100-1000Hz.
