Abstract
A sound absorbing glass building component or transparent synthetic glass building component is provided with holes penetrating through it and is disposed at a distance from a surface, such as a wall, ceiling, window or door. The glass building component is formed as a panel having microperforated holes having a diameter of 0.1-2.0 mm, the holes being spaced 2-20 mm apart and the panel having a thickness of 0.2-30 mm.
Claims20
A sound absorbing arrangement comprising a panel formed of glass or synthetic glass, said panel having first and second surfaces defining a panel thickness, said first surface being located at a distance from a building component surface and facing said building component surface such that said first surface and said building component surface define an air space therebetween, said second surface facing away from said building component surface and being exposed to an ambient atmosphere and soundwaves travelling through said ambient atmosphere, said panel defining a plurality of microperforated holes extending through said panel thickness to communicate said ambient atmosphere located opposite said building component surface with said air space.
