Abstract

The time history of the sound pressure level (SPL) of a passing high-speed train is asymmetric. In this paper, the noise generated by a high-speed train was investigated, and the influence factors of the time history of the SPL were analyzed. The difference in the sound travel time from each part of the train to the receiver was the primary reason for the asymmetry. An improved calculation method was proposed by introducing a propagation time correction. The calculated curve derived from the optimized method was consistent with the measured data acquired from the China Beijing–Shanghai Railway.
