Abstract (en)
[origin: WO2019078726A1] A sound-absorbing panel consisting of a supporting core designed as a truss (2), wherein pads (1) of felt or other suitable material are placed within or fastened to the openings (3) of the truss (2). The truss may have a plane, curved or double-curved design. When all the openings (3) in the truss (2) are filled, a closed sound-absorbing panel plane is formed. By omitting to fill some of the openings (3), a transparent sound-absorbing panel plane is formed. The openings (3) in the truss (2) may be compared with the pixels of a television or computer screen. By filling the openings (3) with different material and colour qualities, the panels may appear in countless variations of patterns, images, colours and materials.
