Title (EN) HYBRID ACTIVE NOISE REDUCTION DEVICE FOR REDUCING ENVIRONMENTAL NOISE, METHOD FOR DETERMINING AN OPERATIONAL PARAMETER OF A HYBRID ACTIVE NOISE REDUCTION DEVICE, AND PROGRAM ELEMENT
(FR) DISPOSITIF DE RÉDUCTION DU BRUIT ACTIF ET HYBRIDE PERMETTANT DE RÉDUIRE LE BRUIT AMBIANT, PROCÉDÉ DE DÉTERMINATION D'UN PARAMÈTRE FONCTIONNEL D'UN DISPOSITIF DE RÉDUCTION DU BRUIT ACTIF ET HYBRIDE, ET ÉLÉMENT DE PROGRAMME
Abstract: front page image
(EN)A hybrid active noise reduction device for reducing environmental noise is provided, the device (500) comprising a microphone (102) for receiving a noise signal (118) and for transmitting a microphone signal (122), a filter unit (114) for receiving the microphone signal (122) and for transmitting a filtered microphone signal (514), the filter unit (114) comprising a low- latency filter part (501) and a high- latency filter part (112), the low- latency filter part (501) and the high- latency filter part (112) being arranged in series to one another, and a loudspeaker (110) for transmitting a noise reduction signal (120) based on the filtered microphone signal (514). A bypass line (505) is arranged in parallel to the high- latency filter part (112) to add the outputs of the low-latency filter (501) and the high-latency filter part (112).
(FR)L'invention concerne un dispositif de réduction du bruit actif et hybride permettant de réduire le bruit ambiant, le dispositif (500) comprenant un microphone (102) permettant de recevoir un signal de bruit (118) et de transmettre un signal de microphone (122), une unité de filtre (114) permettant de recevoir le signal de microphone (122) et de transmettre un signal de microphone filtré (514), l'unité de filtre (114) comprenant une partie de filtre à faible latence (501) et une partie de filtre à haute latence (112), la partie de filtre à faible latence (501) et la partie de filtre à haute latence (112) étant disposées en série, et un haut-parleur (110) permettant de transmettre un signal de réduction du bruit (120) sur la base du signal de microphone filtré (514).
