Title (EN) SOUND WAVE ABSORPTION MODULE AND DEVICE COMPRISING SAME
(FR) MODULE D'ABSORPTION D'UNE ONDE SONORE ET DISPOSITIF LE COMPRENANT
Abstract:
(EN) The sound wave absorption module (1) comprises a perforated central conduit (20) in which a sound wave is intended to propagate, a casing (10) extending at a distance from and facing the central conduit, in a coaxial manner, an absorption chamber (40) partially delimited by the central conduit and the casing, and a resiliently deformable pocket (30) positioned in the absorption chamber in such a way as to at least partially surround the central conduit, the pocket containing an absorption fluid (31).
(FR) 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).
