摘　　要：在研究国内外相关铁路列车运行辐射噪声测量标准的基础上,结合大量的试验数据与现场测试经验分析成果,研究并提出我国高速铁路列车运行辐射噪声关键测量参数测量量和测量点位的选取建议:(1)高速铁路列车运行辐射噪声测量量应选择LAeq,Tp;(2)高速铁路列车运行辐射噪声测试中,以距轨道中心25.0m、距轨面高度3.5m和距轨道中心7.5m、距轨面高度3.5m两个测点作为标准测点。Based on the study of measurement standards of train operation radiated noise of high speed railway (HSR) at home and abroad and taking mass test data and the analysis results of field test into account, the paper proposes the selecting suggestions about key measurement parameters for train operation radiated noise of HSR in China:(1) Measurement quantity for train operation radiated noise of HSR shall select LAeq,Tp;(2) During the radiated noise test, there shall be two standard measurement points. One is 25.0 m from the track center and 3.5 m above the track surface, and the other is 7.5 m from the track center and 3.5 m above the track surface.
