摘要
为了解和掌握环境背景噪声对边界噪声监测结果的影响情况,本文就此作了相应的探讨。结果显示:当测量值与背景值的差值超过10 dB(A)时,可以忽略背景值对测量结果的影响;当测量值与背景值的差值为3~10 dB(A)时,应分段考虑背景值的修正;当测量值与背景值的差值小于3 dB(A)时,应重新选择时间进行测定。
The paper discussed environmental background noise influenced monitoring result of boundary noise, the result showed if margin of monitoring value and background value exceeded 10 dB(A), ignored background value, ff margin of monitoring value and background value was 3 - 10 dB(A), corrected baekground value, if margin of monitoring value and background value less than 3 dB(A), remonitored noise other time.
