Perforated plate for the acoustic correction of premises, consisting of a plasterboard or other appropriate material, forming on its back face a cavity filled with a material that absorbs sound and whose thickness is perforated by a series of holes that allow the passage of the vibrations until they are absorbed by the subsequent absorbent material; characterized in that the holes that perforate this plate, are of two or more different dimensions and are irregularly distributed on the surface of the plate and mixed, also irregularly, the holes of greater diameter with those of smaller diameter, to obtain an irregular distribution of these holes in the plate, which improves the appearance of the plate and the acoustic correction of the room.
