Acoustic absorption structure comprising a partitioning system provided with at least one foot

An acoustic absorption structure including an acoustically resistive layer, a reflective layer and a cellular structure inserted between the acoustically resistive layer and the reflective layer, said cellular structure including walls, one or more of which delimit tubular cells from other tubular cells, the walls being closed at each of their ends by the acoustically resistive layer and the reflective layer, said cellular structure also including at least one partitioning system;

• wherein the partitioning system is individual, placed in a single cell and comprises:
• a partition configured to separate the cell into first and second compartment, having a peripheral edge in contact sealingly with the wall or walls delimiting the cell in which the partition is placed,
• at least one opening passing through the partition and placing the first and second compartments in communication,
• at least one conduit which has a first end rigidly secured to the partition surrounding the opening and a second end at a distance from the partition and spaced apart from the reflective layer, and
• several feet independent of the conduit, which each have a first end connected directly to the partition and a second end in contact against the reflective layer.
