Title (EN) MODULAR SYSTEM FOR NOISE REDUCTION
(FR) SYSTÈME MODULAIRE DE RÉDUCTION DE BRUIT
(ES) SISTEMA MODULAR DE REDUCCIÓN DE RUIDO
Abstract:
(EN) The invention relates to a system, comprising a number of portable noise-reduction devices for actively reducing the levels of acoustic noise in external locations generated by undesired sources of noise. The noise-reduction devices have adaptive capacities for noise attenuation and they are installed around the area of noise generation. The noise-reduction devices have their own capacity for processing signals or this is centrallised in an acoustic processing unit. Said unit consists of an adaptive phase shift and phase correction unit, and a unit for controlling the speakers, which synthesises the sound components required for reducing the perceptible noise.
(FR) L'invention concerne un système composé de divers dispositifs portatifs de réduction de bruit pour réduire activement les niveaux de bruit acoustique dans des lieux extérieurs produits par des sources de bruit non désirées. Les dispositifs de réduction de bruit ont la capacité adaptative d'atténuer le bruit et sont installés autour de la zone de production de bruit. Les dispositifs de réduction de bruit ont leurs propres capacités de traitement des signaux ou celui-ci est centralisé dans une unité de traitement acoustique. Cette unité consiste en une unité adaptative de décalage de phase et de correction de phase, et une unité de commande des enceintes, qui synthétise les composantes de son nécessaires pour réduire le bruit perceptible.

Los dispositivos de reducción de ruido tienen sus propias capacidades de procesamiento de señales o está centralizada en una unidad de procesamiento acústico. Dicha unidad consiste en una unidad adaptativa de desfase y corrección de fase, y una unidad de control de las bocinas, que sintetiza las componentes de sonido requeridas para reducir el ruido percibible.
