Patent

CA 2759084

The invention relates to an apparatus and a method for the binaural reproduction of audio sonar signals (20), which can be direction-selectively received by a sonar system having a receiving antenna 2, which is provided with a plurality of transducers 54, and at least one direction generator 4, and which can be modified by way of binaural audio signal processing 18. The apparatus comprises a portable sound reproduction device 22, particularly a headphone, and a head tracking sensor 24 connected to the sound reproduction device 22 for registering position changes of the sound reproduction device 22. Signals 26, associated with the position changes, are generated, which are transferred to the direction generator 4, in order to select a direction of the sound waves to be received.

L'invention concerne un dispositif et un procédé pour effectuer une restitution binaurale de signaux sonar audio (20) qui peuvent être reçus par sélection de direction, au moyen d'une installation sonar comportant une antenne de réception (2) qui présente une pluralité de transducteurs (54), et au moins un générateur de direction (4), lesdits signaux pouvant être modifiés par traitement binaural de signaux audio (18). Le dispositif selon l'invention comprend un dispositif de restitution sonore (22) portatif, notamment un casque d'écoute ainsi qu'un détecteur de mouvements de la tête (24) pour détecter des variations de position du dispositif de restitution sonore (22). Des signaux (26) associés aux variations de position sont produits, lesdits signaux étant transmis au générateur de direction (4) afin de sélectionner une direction des ondes sonores reçues.
