Abstract (en)
The noise absorbing panel has a profiled surface and through openings. It has at least two superimposed and connected groups of beams (2,3) formed of hardenable material such as cement. The beams in each group are spaced to define openings. The beams in different groups cross at ninety degrees. The beams can be coupled together by cohesion.
