Abstract

L'invention concerne un procédé destiné à améliorer l'acoustique perçue dans un espace, procédé comprenant les étapes suivantes : réception d'au moins un signal sonore, via des moyens récepteurs, à proximité d'au moins une source sonore dans ledit espace ; exécution d'un repliement du signal sonore reçu au moyen, respectivement, d'une fonction de réponse d'impulsion, pour la production de signaux sonores différemment optimisés, la fonction de réponse d'impulsion respective étant choisie, pour l'espace en question, à partir d'une sélection de fonctions de réponse d'impulsion prédéterminées ; reproduction des signaux sonores optimisés, via des moyens de reproduction sonore disposés dans l'espace, un signal sonore optimisé différent étant envoyé à chaque moyen de reproduction sonore et, après un intervalle temporel de commutation, les signaux sonores optimisés sont envoyés auxdits moyens de reproduction, de telle façon que le même signal sonore optimisé ne soit amené en intervalles temporels de commutation se succédant directement, à aucun desdits moyens de reproduction.
