Fast evaluation of the Rayleigh integral and applications to inverse acoustics [PDF]
, 2006 In this paper we present a fast evaluation of the Rayleigh integral, which leads to fast and robust solutions in inverse acoustics. The method commonly used to reconstruct acoustic sources on a plane in space is Planar Nearfield Acoustic Holography (PNAH)
