description	Lèvre avant de nacelle de turboréacteur, comportant un volume annulaire de dégivrage (4) recevant une alimentation en air chaud (40) pour effectuer un dégivrage de ses parois extérieures, cette lèvre comprenant de plus des panneaux acoustiques (42) disposés sur sa paroi sensiblement tournée radialement vers l'axe de la nacelle, caractérisée en ce qu'elle comporte des perçages de sortie d'air chaud (50) qui sont disposés entre l'extrémité avant de la lèvre, et les panneaux acoustiques (42). A front lip of a turbofan engine nacelle is provided, defined at the rear by a partition wall, the lip comprising an annular de-icing space including a tube for supplying hot air in order to de-ice the outer walls thereof, said lip also including acoustic panels arranged on the wall thereof substantially radially facing the axis of the nacelle. The front lip includes hot-air outlet bores/piercings which are arranged between the front end of the lip and said acoustic panels, which allow a flow of hot air, from said annular space, forming a substantially regular film which covers said acoustic panels with a boundary layer in order to heat said acoustic panels.
