摘要
在工业企业厂界噪声实际监测中,对于差值小于3和不为整数时按照GB/T12349-90《工业企业厂界噪声测量方法》进行噪声背景值修正,常会与实际值产生较大误差。通过对三种修正值取值方法进行误差分析,在遵循GB/T12349-90《工业企业厂界噪声测量方法》的情况下,对噪声背景值的修正进行补充细化。
In industrial enterprise factory boundary noise actual monitor.Usually there is a big error between the actual and the noise background value.Which is revised when the difference（between them） is smaller than 3 and not the inter according to GB/T12349 90 ＂Industrial Enterprise Factory Noise Measurement Method＇.Through the error analysis of the three methods getting corrected wdues, the noise background value revision will be supplemented thin,following GB/T 12349-90 ＂Industrial Enterprise Factory Noise Measurement Method＂.
