Abstract

La présente invention a pour objet un procédé et un dispositif de contrôle de la propagation d’ondes acoustiques au voisinage d’une paroi, le procédé et le dispositif mettant en œuvre un dispositif maître pour contrôler un ensemble Nc de cellules (1) constituées principalement d’un haut-parleur (11), d’un ensemble de Nm microphones (10) reliés audit haut-parleur, et d’une unité de commande (12), aux moyens de lois de commande déterminant l’intensité du signal électrique qui doit être envoyé à chaque haut-parleur (11) de manière à obtenir une impédance acoustique généralisée déterminée cible pour chaque haut-parleur, de sorte qu’une fraction des ondes acoustiques est absorbée par la membrane de chaque haut-parleur (11).
