摘　　要：针对测量结果修正的相关要求,本文对新颁布的《工业企业厂界环境噪声排放标准》(GB 12348—2008)和旧标准《工业企业厂界噪声测量方法》(GB/T 12349—1990)在实际工作中的运用进行了比对、分析和探讨,并根据实际工作经验,提出了在背景噪声难以测量的一些特殊情况下的几种解决途径,主要提出噪声源声值与背景声值相差小于3 dB(A)时的解决方案。Directing against the correction of measuring result in the 《Emission standard for industrial enterprises noise at boundary》（GB12348-2008） and the《Method of measuring noise at boundary of industrial enterprises》（GB/T 12349-1990）, analysis and comparison in practical application were carried out. Several resolving methods are proposed for some complex situation in background noise measuring which are hard to handle. The emphases is a resolving method when the differentials is less-than 3 dB（A） between source noise and background noise.
