摘要： 采用噪声与振动测试分析系统，对地铁车辆进入站台和驶出站台及站台广播噪声进行测试与分析。通过对数据分析得出：站台主要噪声源为车辆通过站台时的轮轨噪声与车辆制动啸叫声的叠加，等效声级81.5 dB(A)，频率范围200~4 000 Hz。无车辆通过时广播噪声为主要噪声源，等效声级为79.1 dB(A)，频率范围为500~1 000 Hz。该研究结果对地铁车站的减振降噪设计具有较高的现实意义和应用价值。

Abstract: The noise environment on platform of metro station is investigated for platform conditions as the train goes in, goes out and without train respectively by measurements using noise and vibration analysis system. The results show that superposition of weeltrack noise and squealing noise of braking is predominant in noise sources, and the equivalent noise level is 81.5 dB(A), frequency range 200～4 000 Hz when train goes in. For the platform without train the equivalent noise level measured is 79.1 dB(A), 500～1000 Hz mainly from broadcast in the station. These data are of value for reference in noise control design of metrostation.
