为研究新建城市轨道交通高架车站设备房和管理用房噪声现状及特点，以及巡视设备房工作人员的累积噪声暴露量，选取某线的ZFL站、GML站和HQ站，对其六类设备房及管理用房进行了实地测量，并对噪声测量结果进行分析。结果显示：设备房中最大噪声为400 V开关柜室74 dB（ A）。三个站六类设备房噪声在56～74 dB（ A）之间。管理用房噪声在53～65 dB（ A）之间。站厅噪声随人流多少而变化，低频声较高。巡视设备间工作人员最大噪声暴露量是65dB（ A）。

In order to study the noise level and characteristics of equipment and management room for a newly built elevated station of urban rail transit , and to know the noise exposure of equipment inspection staffs , three stations of a urban rail transit line , the ZFL station, GML station and HQ station were selected , and six kinds of equipment and management rooms were practically measured , and the measurement results of noise were analyzed .It showed that the maximum value LAeq was 74dB(A) in 400V switch cabinet room , and LAeq was between 56~74 dB(A) in six kinds of equipment room of three stations .The average of LAeq ranged from 53 to 65 dB(A) in the management room.The noise of station hall changed with the passenger flow , and was higher at low frequency .The maximum noise exposure LAeq was 65dB(A) for staffs to inspect equipment.
