Acoustically resistive layer for an acoustical attenuation panel, panel using such a layer

   
   

An acoustically resistive layer for an acoustic attenuation panel (22) forming a conduit in which there is an aerodynamic flow (18), adapted particularly for an aircraft turbo jet engine. The panel has at least one acoustically resistive layer (24), at least one porous structure (26) and a reflector (28) disposed opposite the incident wave. The acoustically resistive layer (24) is constituted by strips (30) disposed in the direction of the flow (18), interconnected by a plurality of splints (32) ensuring the absorption of force, particularly radially, the splints (32) having very small surfaces ensuring the continuity of the homogeneous character of the quantity of open surface of the acoustically resistive layer thus formed.
