Title (EN) APPARATUS FOR ACOUSTICALLY IMPROVING AN ENVIRONMENT AND RELATED METHOD
(FR) APPAREIL ET PROCEDE PERMETTANT D'AMELIORER UN ENVIRONNEMENT DU POINT DE VUE ACOUSTIQUE
Abstract:
(EN) The invention provides apparatus for acoustically improving an environment and a corresponding method. The invention features partitioning means in the form of a curtain (10) for producing a discontinuity in a sound conducting medium, such as air, and for absorbing sound. One or more microphones (12) serve for receiving acoustic energy and for converting it into electrical signals for supply to a digital signal porcessor (14). The processor employs an algorithm for performing a spectral transformation on the electrical signals, and outputs the transformed signals to output means (16) in the form of exciters (36).
(FR) L'invention concerne un appareil et un procédé permettant d'améliorer un environnement du point de vue acoustique. D'une manière spécifique, l'invention concerne un dispositif de séparation se présentant sous la forme d'un rideau (10) destiné à créer une discontinuité dans un milieu conducteur de son, tel que l'air, et à absorber le son. Un ou plusieurs microphones (12) servent à recevoir l'énergie acoustique et à la convertir en signaux électriques destinés à être envoyés à un processeur de signal numérique (14). Ce processeur utilise un algorithme pour effectuer une transformation spectrale des signaux électriques et transmet ces signaux électriques transformés à un dispositif de sortie (16) sous la forme d'excitateurs (36).
