摘要
随着城市化的推进,低频噪声问题日趋严重,对低频噪声源的识别,常规的监测判别方法往往效果不佳或者起不到作用。以某信访案例为例,介绍了利用频域分析法结合倍频程频谱分析,通过寻找特征频率来确定噪声源的方法,并提出采用更多频率段识别噪声源的建议。
With urbanization,the growing problem of low frequency noise,low-frequency noise sources for the identification,monitoring routine identification methods are often ineffective or no effect.On this point,a petition to the case,for example,focuses on the use of frequency domain analysis combined with octave spectrum analysis,by seeking to determine the characteristic frequency of the noise source approach,and propose the use of more frequency noise source identification section of the proposal.
