Title
(EN) PORTABLE DEVICE FOR ADAPTIVE NOISE REDUCTION
(ES) DISPOSITIVO PORTÁTIL PARA REDUCCIÓN ADAPTATIVA DEL RUIDO
(FR) DISPOSITIF PORTATIF DE RÉDUCTION ADAPTATIVE DU BRUIT
Abstract
(EN)
The invention relates to a device and method for reducing noise, in indoor and outdoor areas, from multiple unwanted sound sources or from a single mobile noise source. The device is a set of loudspeakers that consists of multiple panels assembled together in a geometric configuration that depends on the coverage angle of the loudspeakers used. The device implements an active signal-processing method which consists of an estimator of the equivalent noise source, an adaptive phase shifting and correction unit, and a loudspeaker control unit, which synthesises the sound.

Un dispositivo y método para reducir ruido, en áreas interiores y exteriores, de múltiples fuentes de sonido no deseadas o de una única fuente de ruido móvil. El dispositivo es un conjunto de altavoces que consiste en múltiples paneles ensamblados juntos en una configuración geométrica que depende del ángulo de cobertura de los altavoces utilizados. El dispositivo implementa un método activo de procesamiento de señales que consiste en un estimador de fuente equivalente de ruido, una unidad adaptativa de desplazamiento y corrección de fase, y una unidad de control de los altavoces, que sintetiza el sonido.

La présente invention concerne un dispositif et un procédé permettant de réduire le bruit, dans des zones intérieures et extérieures, provenant de multiples sources sonores non désirées ou d'une seule source de bruit mobile. Le dispositif est composé d'un ensemble de haut-parleurs qui consiste en de multiples panneaux assemblés selon une configuration géométrique qui dépend de l'angle de couverture des haut-parleurs utilisés. Le dispositif met en oeuvre un procédé actif de traitement de signaux qui implique une unité d'estimation de source équivalente de bruit, une unité adaptative de déplacement et de correction de phase et une unité de commande des haut-parleurs qui synthétise le son.
