摘　　要：随着地铁线网建设的不断扩大和运营事业的发展,地铁所带来的噪声污染已经引起了人们的高度关注。文章以广州地铁修造车为研究对象,根据相关标准,采用声学分析仪对广州地铁修造车进行运行内部噪声测试,通过对测试结果进行分析,得出其噪声水平及分布规律,并进一步为修造质量控制以及新线设计提供依据。With the expansion of the subway network construction and the development of the operational cause, metro noise pollution has aroused people＇s high attention. This paper takes a Guangzhou metro overhaul vehicle as the research object. According to the relevant standards, we test the running internal noise of Guangzhou metro overhaul vehicles using acoustic analyzer, and get the noise level and distribution by analyzing the test results. It furtherly provides basis for overhaul quality control and new line design.
