摘要
在城市轨道交通系统中，通信及公共广播系统是仅次于信号系统的重要部分。地铁公共广播主要是指行车的正线广播、车辆段运转库广播和停车场列检库广播等，针对如何提高地铁公共广播的服务质量，更人性化，在设计中引入了各种新技术，从而改变了目前大多数轨道交通的广播然停留在只考虑功能的实现局面，由于广播声效的考虑，抛弃了原来安装中以经验和人耳测试为主的施工方式，设计中在地铁广播功能基础上，引入声效及噪声传感器网络，使地铁广播声效达到一个新高度。
Abstract
In the rail traffic system, the communication and public address systems are the second important parts after the signal system. The metro public address mainly indicates the main track public address, depot operation house public address and park train examining house public address, etc. For the question how to improve the service quality of metro public address and make it more humanized, various new technologies are introduced, so that the situation that currently most rail traffic public address systems just concern the realization of functions is changed. Considering the sound effects of public address, the experience and human ear test based construction mode originally used in the installation is abandoned, and the sound effect and noise sensor network is introduced to the design on the basis of metro public address functions, making the sound effect of metro public address to a new height.
