ABSTRACT:
A sound-absorbing building panel for lining of the inside walls and ceilings, in particular ceiling tile, consists of a carrier panel to be arranged spaced from a wall, which carrier panel is advantageously a perforated sheet metal and to which on at least one side a sound-absorbing, microporous layer is applied. Such a building panel, which does not require an insulation layer as a backing and can, moreover, be manufactured inexpensively, has a sound-absorbing layer of granules which are surrounded on all sides by an adhesive coating. The granules are essentially designed ball-shaped and are adhesively connected together at point-like connections and to the carrier panel. The granules also have a diameter between 0.1 to 0.9 times of the hole diameter of the carrier panel.
