Noise dampers of sound absorbent material are inserted on the metal grid beams in a suspended ceiling.Hangers, embedded in a structural ceiling, that support the beams, are insulated from the beams by the noise dampers.Sound vibrations generated in the structural ceiling, which is often a floor, are not transmitted through the hangers, to the suspended ceiling, or to the room, below, but are absorbed in the dampers before reaching the grid beams.
