The reconstruction of sound sources by using inverse methods is known to be prone to estimation errors due to measurement noise, model mismatch, and poor conditioning of the inverse problem. This paper introduces a solution to map the estimation erro

Source localization and quantification by an acoustic array of microphones depend to a great extent on an accurate knowledge of the antenna position towards the radiating device. The present work details a methodology to determine the location of the

Iterative positioning of microphone arrays for acoustic imaging

Autor: Laurent Gilquin, Pierre Lecomte, Jérôme Antoni, Clément Marteau, Thibaut Le Magueresse

For the characterization of acoustic sources, a common approach is to retro-propagate the sound pressure measured with a microphone array, which is often performed through the resolution of an inverse problem. The ill-posed nature of this problem, as

International audience; In a previous work, an attempt was made to give a unified view of some acoustic holographic methods within a Bayesian framework. One advantage of the so-called “Bayesian Focusing” approach is to introduce an aperture funct

Bayesian regularization applied to real-time near-field acoustic holography

Autor: Jean-Hugh Thomas, Jérôme Antoni, Sébasien Paillasseur, Thibaut Le Magueresse

Publikováno v: The Journal of the Acoustical Society of America. 136:2171-2171

Real-Time Near-field Acoustic Holography is used to recover non stationary acoustic sound sources using a planar microphone array. In the direct way, describing propagation requires the convolution of the spatial spectrum of the source under study wi
