Acoustically absorbent cell for acoustic panel
First Claim
1. An acoustically absorbent cell for an acoustic panel, comprising a layer with a porous matrix incorporating a plurality of acoustic resonators between a first face and a second face of the porous matrix, wherein the resonators are ordered so that, in a direction extending substantially perpendicular to the first face and the second face, at least one first resonator is arranged between the first face and a second resonator, and at least one second resonator is arranged between the second face and the at least one first resonator.

Abstract
An acoustically absorbent cell for an acoustic panel, comprising a layer with a porous matrix incorporating a plurality of acoustic resonators between a first face and a second face of the porous matrix is described. The resonators are ordered so as to form at least two substantially parallel rows each comprising at least two resonators and extending along the first and second faces.
