Abstract
An acoustic treatment device for an aircraft propulsion assembly includes two skins that enclose an acoustic structure. The acoustic structure has a cellular structure with hollow cells and a structure of shapes with protruding shapes, each of which is engaged in a different hollow cell of the cellular structure. The structure of shapes additionally has stubs designed to fit into the hollow cells of the cellular structure and to allow the acoustic treatment device to be fixed to a component of the aircraft propulsion assembly.
