Abstract

Le module d'absorption d'une onde sonore (1) comporte un conduit central (20) ajourée dans lequel une onde sonore est destinée à se propager, un carter (10) s'étendant à distance et en regard du conduit central de manière coaxiale, une chambre d'absorption (40) délimitée en partie par le conduit central et le carter, et une poche (30) déformable élastiquement positionnée dans la chambre d'absorption de sorte à entourer au moins en partie le conduit central, la poche contenant un fluide d'absorption (31).
