Abstract
An acoustic treatment panel including a porous acoustically resistive structure which includes at least one external layer which is in contact with the external environment and which has through holes, internal strips including several openings which communicate with the inside of the cells of the panel and connecting canals, interposed between the external layer and the internal strips, which ensure that the floor-section openings communicate with at least one through hole of the external layer.
Claims9
An acoustic treatment panel comprising:
- a porous acoustically resistive structure in contact with an external environment in which during operation sound waves travel;
- a reflective layer and at least one cellular structure positioned between the porous acoustically resistive structure and the reflective layer and configured to compartmentalize a zone between the porous acoustically resistive structure and the reflective layer into a plurality of cells;
- the porous acoustically resistive structure comprising at least one external layer in contact with the external environment and which has through holes;
- and
- internal strips, each of the internal strips comprising openings which communicate with an inside of the cells and connecting canals, interposed between the external layer and the internal strips, which communicate with at least one of the through holes of the external layer, and with at least one of the openings of one of the internal strips.
