摘要： 在高速动车组减振降噪设计中，声品质已成为舒适性评价的重要指标之一。以Zwicker提出的对噪声进行主观评价的客观量化方法为基础，通过响度、尖锐度、粗糙度和抖动强度4种噪声客观评价参量计算方法对某高速铁路动车组车内噪声试验测试数据进行分析，得到车内典型位置不同运行速度时各心理声学参量的现状和分布规律，可为高速铁路动车组车内声品质研究提供参考依据。

Abstract: In vibration and noise reduction design of high speed train, sound quality has become an important indicator of comfort evaluation. In this paper, based on the theory by Zwicker who presented objective quantificational methods for subjective evaluation of the noise, the experimental data of internal noise of high speed railway trains is analyzed through the calculation of four objective evaluation parameters of noise: loudness, sharpness, roughness and fluctuation strength. Finally, the status and distribution regulations of various psychoacoustics parameters are obtained in the typical position of the train driven at several constant speeds. This work provides some reference basis for sound quality research of the high speed railway trains.
