Abstract
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).
