Abstract:
(EN) The present technology relates to a signal processing device and method, and a program capable of improving noise canceling performance. The signal processing device includes: a noise detection unit for detecting the noise generated within a control region created by a microphone array; and a control unit for controlling the update of the filter coefficient for an adaptive filter used to generate the signal for a sound output from a speaker array on the basis of detecting noise generated within the control region to reduce the external noise generated by the speaker array toward a noise-canceling region. The present technology is applicable to a spatial noise control device.
(FR) La présente invention concerne un dispositif et un procédé de traitement de signal, et un programme capable d'améliorer les performances d'annulation de bruit. Le dispositif de traitement de signal comprend : une unité de détection de bruit destinée à détecter le bruit généré à l'intérieur d'une région de commande créée par un réseau de microphones; et une unité de commande destinée à commander la mise à jour du coefficient de filtre pour un filtre adaptatif utilisé pour générer le signal pour une sortie sonore provenant d'un réseau de haut-parleurs sur la base de la détection du bruit généré à l'intérieur de la région de commande afin de réduire le bruit externe généré par le réseau de haut-parleurs vers une région d'annulation de bruit. La présente invention peut être appliquée à un dispositif de réduction de bruit spatial.
