IMPROVING THE NEAR-FIELD ACOUSTICAL HOLOGRAPHY RESULTS BY USING THE REGRESSIVE DISCRETE FOURIER SERIES [PDF]
International audienceThe planar Near-field Acoustical Holography (NAH) is a non-contact technique that can be used to estimate the vibration pattern of a planar body from the sound pressure it produces on a planar microphone array.

Characterization of High-Power Rocket and Jet Noise Using Near-Field Acoustical Holography [PDF]
Structural fatigue, hearing damage, and community disturbances are all consequences of rocket and jet noise, especially as they become more powerful. Noise-reduction schemes require accurate characterization of the noise sources within rocket plumes and ...

Numerical techniques for near-field acoustic holography
Near-field acoustic holography (NAH) has proved to be an enormously successful sound source identification technique, which is widely used in field of acoustics and noise control. The work presented in this thesis aims at developing a novel method for modelling near-field acoustic holography, where the particle velocity on the surface of a vibrating ...
