The use of partially measured source data in near-field acoustical holography based on the BEM [PDF]
, 2000 In applying the conformal near-held acoustical holography (NAH) to actual source identification problems, it is often possible to determine the velocity at certain points of the source surface in advance.

Data extrapolation method for near-field acoustic holography
Journal of the Acoustical Society of Japan (E), 1998 We propose a new data smoothing method for near-field acoustic holography (NAH) with the aid of the data extrapolation. This method can reduce the error energy which comes from the finiteness of the measurement aperture. We illustrate our calculational results by using of the computer simulations which apply to the numerically generated data by Fast ...

The Development of an Energy-Based Near Field Acoustical Holography Technique [PDF]
, 2007 Nearfield Acoustical Holography (NAH) is an acoustic imaging technique that has been traditionally based on pressure measurements. A NAH technique has been developed that allows for energy density (ED) to be propagated.
