ACOUSTIC PANEL

摘要

The invention concerns an acoustically absorbent cell (22, 48) for an acoustic panel, comprising a layer (32) having a porous matrix incorporating a plurality of acoustic resonators (A1-A4, Bi-B6) between a first face (30, 54) and a second face (28, 56) of the porous matrix (32). According to the invention, the resonators (A1-A4, Bi-B6) are, for example, ordered in such a way as to form at least two substantially parallel rows (24, 26, 50, 52) each comprising at least two resonators and extending along the first and second faces.
