(EN) MODULAR SYSTEM FOR NOISE REDUCTION
(ES) SISTEMA MODULAR DE REDUCCIÓN DE RUIDO
(FR) SYSTÈME MODULAIRE DE RÉDUCTION DE BRUIT
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.

Los dispositivos de reducción de ruido tienen capacidades adaptativas de atenuación de ruido y son instalados alrededor del área de generación de ruido. 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.
