Abstract: The distributed source boundary point method (DSBPM) is proposed to be a transform algorithm of nearfield acoustic holography (NAH). The models to reconstruct and predict the acoustic quantities of acoustic field are established. Compared with the boundary element method (BEM) based NAH, the variable interpolation, the numerical calculation and the disposal of singular integral are avoided in this method. And it has such merits as follows:the quick calculation speed, the high calculation precision, the good calculation stability, and the simple and pellucid calculation procedure. So it has a good prospect of application in engineering field.
