Abstract
Sound absorbing panel of cement conglomerate and a procedure for its manufacture.The panel, produced from a block of concrete (1), based on a casting procedure, has the special feature that at least one of the side surfaces (5) has orifices (3) open to the outside of this surface (5) and connected internally to a resonance chamber (2) filled with a sound-absorbing material (4), so that when the surface (5) with the holes (3) is facing towards a source of propagation of acoustic waves, there is acoustic attenuation in the range of frequencies characteristic of a known noise source. The sound-absorbing panel is applicable, for example, in the formation of a prefabricated platform for absorbing noise from a vehicle that is running on rails.
