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.
