Title (EN) SYSTEMS, METHODS, AND APPARATUS FOR PRODUCING A DIRECTIONAL SOUND FIELD
(FR) SYSTÈMES, PROCÉDÉS ET APPAREIL DE PRODUCTION D'UN CHAMP SONORE DIRECTIONNEL
Abstract: front page image
(EN)A system may be used to drive an array of loudspeakers to produce a sound field that includes a source component, whose energy is concentrated along a first direction relative to the array, and a masking component that is based on an estimated intensity of the source component in a second direction that is different from the first direction.
(FR)L'invention concerne un système pouvant être utilisé pour entraîner un réseau de haut-parleurs à produire un champ sonore qui comprend un composant source, dont l'énergie est concentrée le long d'une première direction par rapport au réseau, et un composant de masquage qui est basé sur une intensité estimée du composant source dans une seconde direction qui est différente de la première direction.
