Original Abstract

Near field acoustic holography (NAH) is an experimental technique for analysing sound fields near sources. A simulation study has been carried our, and this paper examines and compares i) classical planar NAH based on spatial transforms (single layer NAH), ii) a similar technique based on measurements in two parallel planes (double layer NAH), and iii) a method that avoids spatial transforms (and thus leakage) by using statistical considerations (SONAH).
