The invention relates to a coating for the acoustic treatment of the surface of an aircraft, especially at the level of a leading edge such as the air intake of an aircraft nacelle, said coating including an acoustically resistive layer, at least one cellular structure (30) and a reflective layer, said cellular layer (30) including a plurality of ducts giving, on the one hand, onto a first imaginary surface (34) and, on the other hand, onto a second imaginary surface (36), characterised in that the cellular structure (30) includes cut-outs or openings (38) formed at the side walls of some ducts for establishing a communication between adjacent ducts in order to create a network of communicating ducts that isolate at least one non communicating duct or group of ducts, one at least of said communicating ducts being connected to at least one hot-air inlet (40).

L'objet de l'invention est un revêtement pour le traitement acoustique rapporté au niveau d'une surface d'un aéronef, notamment au niveau d'un bord d'attaque tel qu'une entrée d'air d'une nacelle d'aéronef, ledit revêtement comprenant une couche acoustiquement résistive, au moins une structure, alvéolaire (30) et une couche réflectrice, ladite structure alvéolaire (30) comprenant une pluralité de conduits débouchant d'une part au niveau d'une première surface imaginaire (34), et d'autre part, au niveau d'une seconde surface imaginaire (36), caractérisé en ce que la structure alvéolaire (30) comprend des découpes ou des orifices (38) ménagés au niveau des parois latérales de certains conduits permettant de faire communiquer des conduits adjacents de manière à créer un réseau de conduits communicants isolant au moins un conduit ou un groupe de conduits non communicants, au moins un des conduits communicants étant reliés à au moins une arrivée de gaz chaud (40).
