摘    要:声强测量技术在声功率测量、噪声源识别等方面有着广泛的应用,是近年来发展起来的一项重要的声学测量技术。但在实际测量中由于传声器间的相位失配会引起声强测量的误差。通过分析残余声强的产生原因,阐述了其对于声强测量精度的影响,并通过实际测量声压残余声强指数来对声强测量结果进行了评价。

关 键 词:声强  声压  相位失配  评价

Abstract:Sound intensity measurement is an important measuring technique developed lately which has a wide application in sound power measurement and recognition of sound sources. But in practice, there is always error due to phase mismatch for intensity measurements. In this treatise, the author analyzed the cause of residual inten- sity and the effect on the measure accuracy. Finally, the author used the pressure-residual intensity index in the e- valuation of an intensity measurement' s accuracy.
Keywords:sound intensity  sound pressure  phase mismatch  evaluation
