<p>A process for the production of a panel with a protective acoustic damping layer. The protective layer includes at least one porous core covered, on the one side, with a porous acoustic damping layer and on the other side with an acoustic reflector. The porous damping layer is emplaced by striping or draping. The porous damping layer consists of parallel strips. Edges of the strips of the porous damping layer are positioned facing a strip deposited by striping or draping and containing a thermoplastic, thermosetting or thermofusible material adapted, by subsequent heating, to ensure the securement of the edges of said strips of the porous damping layer with the adjacent strip of thermoplastic, thermosetting or thermofusible material.</p> |
