摘　　要：高速动车组运行速度越高,车内低频段噪声就越显著,乘坐的舒适性也会越差。为了提高高速动车组乘坐的舒适性,降低噪音对乘客的影响,高速动车组在设计过程中采用各种降噪技术来满足相关标准的要求,满足乘客对舒适坐乘环境的要求。The higher the speed of high-speed EMUs,the more pronounced the low-frequency noise inside the vehicle and the worse the ride comfort.In order to improve the comfort of high speed EMU and reduce the influence of noise on passengers,high speed EMU adopts various noise reduction techniques to meet the requirements of relevant standards during the design process,and meet the requirements of passengers for comfortable sitting and riding environment.
