Abstract
An acoustic treatment panel that is connected to an air intake of an aircraft nacelle, includes at least one acoustically resistive structure () and a reflective layer (), between which are located—in a direction that is essentially perpendicular to the longitudinal direction of the nacelle—bands () of alveolar cells spaced in such a way as to allow the passage of hot air provided for a frost treatment, characterized in that it includes pipes () for hot air that are each delimited by at least one partition that extends from the acoustically resistive layer () up to the reflective layer () in such a way as to insulate the bands () of cells in the longitudinal direction.
