Partial coherence decomposition (PCD) and singular value decomposition(SVD) are two mostly used methods in multi-reference near-field acoustic holog raphy. In order to obtain application availability of the two methods systematically, influences of factors such as reference microphone locations, level differences between sources, measurement noise are investigated deeply. Research results demonstrate that reconstruction via PCD is superior to that via SVD on the basis of accurate reference arrangement, and this conclusion is validated by experiment.
