Ce projet de doctorat consiste en la proposition d'une solution technologique d'un résonateur de Helmholtz adaptatif à volume variable, permettant ainsi de s'affranchir du caractère mono-fréquentiel des résonateurs de Helmholtz passifs. Le réglage de volume s'effectue grâce à l'utilisation d'une membrane en polymère électroactif (EAP), permettant ainsi d'accorder les résonances du résonateur de Helmholtz. Le comportement mécanique de ces matériaux est modifié lorsqu'ils sont stimulés par un champ électrique. Des améliorations significatives en perte par transmission acoustique sont obtenues en basses fréquences par deux effets: la variation de raideur de la membrane et l'augmentation de volume due à la déformation de la membrane. Des études...
