Abstract
A plate-shaped constructional element comprises a perforated plate made of a solid material such as metal, wood, wood chip board, pressboard, synthetic material or gypsum, and is characterized by the provision that a micro-perforated sheet or thin plate is disposed on one of the plate surfaces of the plate. One variant provides that the holes in the plate are formed in such a manner that they open each into a micro hole on one side of the plate.
