摘　　要：国家标准(GB12349-90)规定的扣除背景噪声值是一种理想化的状态,在实际监测中常常会遇到背景噪声不能满足测量要求,这使背景噪声的测量结果及修正产生失准,本文分析了这些问题并提出了相应的解决办法。According to the national standard of China,the real level of the noise source to deduct a background value is an ideal state.However,in real monitoring,the background value of boundary noise is not suitable to the work of environmental monitoring.As a result,there is an error for the monitoring result of the background value and its correction.This paper discusses the problems and their solutions.
