An experimental investigation of planar nearfield acoustic holography using pressure and particle velocity measurements
基于声压-振速测量的平面近场声全息实验研究

In the conventional nearfield acoustic holography (NAH),only the pressure or particle velocity is used as the input quantity,and it cannot separate the waves from the two sides of the hologram surface. Therefore,all sources are assumed to be on one side of the hologram surface,i.e. the sound field is assumed to be free. This assumption limits the practical applications of NAH. In the NAH using pressure and particle velocity measurements,both pressure and particle velocity are used as the input quantities. B...
