摘　　要：高速铁路的大规模使用,运行时的噪声随着速度提高而增大,严重影响了所在环境下工作人员和乘客的舒适性,因此开发了一种基于数字信号处理(DSP)的噪声监测系统。该系统以DSP为核心扩展音频采集模块以及存储模块,同时通过上位机实时观察。将该系统安装于动车组内部,对关键部位进行噪声监测。实验结果表明:基于DSP的噪声监测系统能有效满足动车组实时监测的需求。Due to the massive use of high-speed railway,running noise increases with speed which affected the comfort of the staff in the environment seriously. A DSP-based noise monitoring system was designed. The system took DSP as a core and extended audio acquisition module and a storage module,and observed the real-time data through the host computer. The system was installed in EMU for monitoring noise.Experimental results showed that the DSP-based noise monitoring system could effectively monitor the noise of EMU in real time.
