摘要
机场噪声对周边社区居民的健康生活影响越来越突出,解决噪声问题首先要对飞机噪声进行监测;机场噪声实时监测系统采用双核24位Δ-Σ方式的AD采集技术,利用DSP的计算能力,实现飞机噪声数据的高速采集和实时计算;利用计算得到的时间-声级曲线等参数识别飞机噪声事件,并将声暴露级、声压等参数通过网络发送到云端进行处理,得到有利于机场噪声管理所需参考文件。
The impact of airport noise on the healthy life of residents in surrounding communities is more and more prominent.To solve the noise problem,we must first monitor the aircraft noise. Use dual-core 24-bit delta-sigma AD acquisition technology in the airport noise real-time monitor system,and achieved the high speed acquisition and real-time calculation of aircraft noise data by using the computing power of DSP. Aircraft noise event is identified by using parameters such as calculated time-level curves,and the parameters such as sound exposure level and sound pressure are sent to the cloud for processing through the network,which get the necessary reference documents for airport noise management.
