摘    要:本文研究了在混响场中用相关传声器识别主声源直达声的近似工程法,包括理论及实验技术。采用该方法对一个置于混响声污染下的恒定声源进行了直达声测量,并将测量结果与该恒定声源的消声室测量结果进行了比较,结果表明:相关传声器近似工程法在很大程度上能减少混响声对主要源声压测量的干扰,从而能在混响声场中获取一定精度的主声源声压级。

关 键 词:混响场  传声器  声源  直达声  近似工程法

Abstract:In this paper, theoretical and experimental investigations are preseted for a correlationmicrophone measurement method which can be used to indentify a primary source in a field polluted by reverberant noise.The method been experimentally tested and the result was compared with that obtained in an anechoic room. It is found that the correlation-microphone method can to some extent reject the reverberant noise affecting the primary souree.Therefore the method can be used to measure the acoustic data of a primary source in a reverberant noise polluted field.
Keywords:Correlation function  Acoustic measurement  Primary source  Reverberant noise
