Title (EN) SIGNAL ACQUISITION DEVICE FOR ACQUIRING THREE-DIMENSIONAL (3D) WAVE FIELD SIGNALS
(FR) DISPOSITIF D'ACQUISITION DE SIGNAL POUR ACQUÉRIR DES SIGNAUX DE CHAMP D'ONDE TRIDIMENSIONNEL (3D)
Abstract:
(EN) A Signal acquisition device is described for acquiring three-dimensional wave field signals. The signal acquisition device comprises an acoustically reflective plate (PLT) comprising two planar sides facing oppositely and a two-dimensional array of inherently omnidirectional sensors (TSS) arranged on one of the two sides, characterized in that the sound recording device comprises another two-dimensional array of inherently omnidirectional sensors (BSS) arranged on the other of the two sides.
(FR) Un dispositif d'acquisition de signal est décrit pour acquérir des signaux de champ d'onde tridimensionnel. Le dispositif d'acquisition de signal comprend une plaque acoustiquement réfléchissante (PLT) comprenant deux côtés plats se faisant face et un réseau bidimensionnel de capteurs intrinsèquement omnidirectionnels (TSS) disposés sur l'un des deux côtés, caractérisé en ce que le dispositif d'enregistrement sonore comprend un autre réseau bidimensionnel de capteurs intrinsèquement omnidirectionnels (BSS) disposés sur l'autre des deux côtés.
