ABSTRACT:
The panel shaped element finds application specifically for sound absorbing installations. It includes recesses proceeding from both its main surfaces which meet within the element and partially overlap each other. The recesses at one of the sides of the element have, thereby, shapes which differ from the shapes of the recesses at the other side thereof, such that the recesses form passages through the element. The recesses at the absorbing side are arranged in rows and the rows are arranged in a raster-like fashion. One of the sides of the element includes bores and the other side includes grooves. The bores are thereby arranged in rows parallel to the grooves and open into the grooves. Therefore, this panel shaped element can quite easily be selectively designed to cope with specific demands and circumstances by a changing of the relevant diameters.
