复杂声场中单个声源的鉴别和评价是噪声污染控制的重要环节。简要介绍了几种常用的噪声源鉴别方法,然后结合变电站复杂声场中噪声产生的实际情况,针对变电站主要声源噪声的特性提出了两种方法的基本原理和具体操作步骤,即声强测量法和基于波叠加的噪声源识别方法,用以进行变电站中多点噪声源的鉴别。这为建立变电站声场中多点声源鉴别的标准方法提供了可能;对于厂界噪声超过环保部门确定标准的变电站.应用这些方法可以提供明确的治理思路。
複雜聲場中單箇聲源的鑒彆和評價是譟聲汙染控製的重要環節。簡要介紹瞭幾種常用的譟聲源鑒彆方法,然後結閤變電站複雜聲場中譟聲產生的實際情況,針對變電站主要聲源譟聲的特性提齣瞭兩種方法的基本原理和具體操作步驟,即聲彊測量法和基于波疊加的譟聲源識彆方法,用以進行變電站中多點譟聲源的鑒彆。這為建立變電站聲場中多點聲源鑒彆的標準方法提供瞭可能;對于廠界譟聲超過環保部門確定標準的變電站.應用這些方法可以提供明確的治理思路。

The identification and evaluation of single noise source in complex sound field are important links in noise pollution control. Several routine methods to discriminate noises source were introduced. Combined with the characteristic of the complex acoustic field of transformer substation and the characteristic of the main noise sources in transformer substation, two methods were suggested. The first method was named sound intensity measurement, and the other was based an improved wave superposition ap- proach. The foundation principle and the practical steps of each method were introduced separately, which provided possibility to construct standard methods to discriminate the noises source in the complex acoustic field of transformer substation. Straightfor- ward management ideas will be advised by applying the method, in which factory bound noise exceeded the standard proposed by environment protection department.
