Application of New Technologies in Metro Public Address System
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.
