1. A method for manufacturing a soundproofing assembly, said manufacturing method comprising:
a first provision step comprising providing a first panel of honeycomb structure comprising a plurality of cells, each cell of the first panel opening both at a first face of the first panel and at a second face of the first panel, wherein the plurality of cells are joined along nodal joints,
a fastening step comprising fastening an intermediate plate against the second face of the first panel to close off one end of each cell of the plurality of cells of the first panel, wherein an opposing end of each cell of the plurality of cells of the first panel remains open and uncovered,
an adhesive-coating step comprising depositing a layer of adhesive on the intermediate plate on the side opposite the first panel,
a second provision step comprising providing a second panel of honeycomb structure comprising a plurality of cells, each cell of the second panel opening both at a first face of the second panel and at a second face of the second panel, wherein the plurality of cells are joined along nodal joints,
a bonding step comprising bonding the first face of the second panel to the layer of adhesive to close off one end of each cell of the plurality of cells of the second panel, wherein an opposing end of each cell of the plurality of cells of the second panel remains open and uncovered, and
a piercing step comprising piercing the intermediate plate and the layer of adhesive through the open and uncovered cells of the first panel or the open and uncovered cells of the second panel at a bonding zone of the second panel,
wherein an imaging unit captures an image of an open and uncovered opposing end of a cell and transmits this image to a control unit that analyses the image and identifies edges of said cell,
wherein the control unit determines positions for piercings inside these edges and controls a piercing unit so that the piercing unit is positioned successively facing each of the determined positions for the piercings and effects the piercings.
