噪声监测中前景噪声与背景噪声分离方法的研究

为了能够有效的区分前景噪声和背景噪声，本文搭建了一种噪声采集的系统，采用数字噪音计VC824B为噪声采集传感器，单片机作为初级处理端并将噪声数据传输给ARM主控板，再通过通讯板传输给上位机主机。本文提出了在总体噪声的数据中用声强法进行噪声分离。经过实验验证了该方法的可行性，同时为以后提供大规模的噪声采集提供了合理的硬件平台和分析方法。

Study on the method of foreground noise and background noise separation in noise monitoring

In orderto distinguish the foreground and background noises effectively,this paper builds the a noise data acquisition system,using digital noise meter VC824B noise acquisition sensor,microcontroller as the end of the primary treatment and the noise data transmission to the arm main control board,and then transmitted through the communication board to PC host.In this paper,we put forward a method to separate the noise from the data of the total noise.Experimental results show that the method is feasible,and it provides a reasonable hardware platform and analysis method for large scale noise collection.
