| 摘要 |
The invention relates to an acoustically absorbent cell (22, 48) for an acoustic panel, comprising a layer (32) with a porous matrix incorporating a plurality of acoustic resonators (A1-A4, B1-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, B1-B6) are for example ordered so 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. |

1. An acoustically absorbent cell (22, 48, 80, 100, 102) for an acoustic panel, comprising a layer (32) with a porous matrix incorporating a plurality of acoustic resonators (A1-A4, B1-B6, C1-C4, D1-D2) between a first face (30, 54, 86, 108, 118) and a second face (28, 56, 88, 110, 120) of the porous matrix (32), characterised in that the resonators (A1-A4, B1-B6, C1-C4, D1-D2) are ordered so that, in a direction extending substantially perpendicular to the first face (30, 54, 86, 108, 118) and the second face (28, 56, 88, 110, 120), at least one first resonator is arranged between the first face (30, 54, 86, 108, 118) and at least one second resonator is arranged between the second face (28, 56, 88, 110, 120) and the at least one first resonator. |
