Abstract

L'invention concerne un procédé permettant d'obtenir un niveau souhaité de diffusivité de sortie acoustique à partir d'un dispositif acoustique, qui comprend les étapes suivantes: mesure d'au moins deux réponses du dispositif acoustique, l'une étant une réponse de référence, calcul de la corrélation entre chaque réponse mesurée et la réponse de référence, variation d'au moins un paramètre du dispositif acoustique, nouvelle mesure d'au moins deux réponses et calcul de la corrélation entre la nouvelle mesure de réponse de référence et les autres nouvelles mesures de réponse pour chaque variation, en sélectionnant le paramètre ou chaque paramètre du dispositif acoustique qui donne la corrélation la plus proche d'une valeur optimale préétablie, de manière à obtenir la diffusivité souhaitée.
