Abstract
An acoustic treatment panel includes an acoustically resistive layer that defines a surface of an aircraft that is in contact with an aerodynamic stream, a reflective layer () between which are arranged at least one alveolar structure () with a number of cells dedicated to the acoustic treatment, and de-icing cavities () in which hot air circulates in contact with the acoustically resistive layer to ensure a frost treatment, characterized in that it includes holes for supplying de-icing cavities () with hot air and in that the capacity to treat the frost is adjusted along the zones by modifying the open surface ratio that results from the holes.
