The invention relates to an aircraft nacelle that comprises a duct (32), a peripheral wall (34), a front lip (36) connecting said duct (32) and said peripheral wall (34) and defining an air inlet, as well as an ice treatment system for treating an area extending along a longitudinal section from a point A at the peripheral wall (34) to a point B at the duct (32) and including a front frame (38) defining together with said lip (36) a duct (51) in which flows hot air for de-icing, wherein said duct (32) includes an acoustic-treatment coating (44) that comprises, from the inside to the outside, a reflecting layer, at least one cellular structure and at least one acoustically-resistive structure, characterised in that the front frame (38) includes a junction area with the lip (36) and/or the duct (32), that is offset towards the front of the nacelle relative to point B, wherein ducts (50) are provided at the inner face of the lip (36) and of the duct (32) in order to direct hot air from said hot-air duct (51) to outlets provided at a circle corresponding to point B, said ducts (50) extending beyond the junction area between the front frame (38) and the lip (36) and/or the duct (32), and being defined by at least one wall that insulates the hot air of the coating (44) for the acoustic treatment.

L'objet de l' invention est une nacelle d'aéronef comprenant un conduit (32), une paroi périphérique (34), une lèvre (36) à l'avant reliant ledit conduit (32) et ladite paroi périphérique (34), ainsi qu'un système de traitement du givre comportant un cadre avant (38) délimitant osec ladite lèvre (36) un conduit (51) dans lequel circule de l'air chaud pour le dégivrage, ledit conduit (32) comprenant un revêtement (44) pour le traitement acoustique, comportant de l'intérieur vers l'extérieur, une couche réf lectrice, au moins une structure alvéolaire et au moins une structure acoustiquement résistive du cadre avant (38) comprend une zone de jonction os/ec la lèvre (36) et/ou le conduit (32) décalée vers l'avant de la nacelle par rapport au point B, des conduits (50) étant prévus au niveau de la face intérieure de la lèvre (36) et du conduit (32) pour acheminer l'air chaud depuis ledit conduit (51) pour l'air chaud jusqu'à des sorties disposées au niveau d'un cercle correspondant au point B, lesdits conduits (50) s' étendant au-delà de la zone de jonction entre d'une part le cadre avant (38), et d'autre part la lèvre (36) et/ou le conduit (32) et étant délimités par au moins une cloison qui isole l'air chaud du revêtement (44) pour le traitement acoustique.
