一、前言 目前,声强测量已越来越多地用于机械噪声研究。最普通的声强测量法就是用一对靠得很近的传声器作为探测器。最近许多刊物介绍了这种方法及其可能的误差[1—7]。 对于声强测量,虽然每对传声器可能有三种配置方法,但目前仅使用两种方法,即边靠边配置和面对面配置。Fahy I. Introduction At present, the sound intensity measurement has been used more and more for mechanical noise research. The most common sound intensity measurement method is to use a pair of close microphones as detectors. Many publications recently introduced this method and its possible errors [1-7]. For sound intensity measurement, although there may be three configuration methods for each pair of microphones, only two methods are currently used, edge-by-edge configuration and face-to-face configuration.
