Abstract: A damp rail assembly for a garage door opening system is provided. The rail assembly includes a beam member configured for mounting to a support structure, and for slidably supporting a trolley member. A viscoelastic laminate structure is attached to the beam member to absorb and attenuate vibration and structure-borne noise directly therefrom. The viscoelastic laminate structure includes a constraining layer and a viscoelastic layer spanning substantially the entirety of the constraining layer and bonded thereto. The viscoelastic laminate structure may include a plurality of planar viscoelastic laminate structures each having an adhesive layer spanning substantially the entirety of a respective viscoelastic layer such that each of the planar viscoelastic laminate structures may be individually adhered at different predetermined locations along the beam member. Alternatively, the viscoelastic laminate structure and beam member may be preformed as a single, unitary structure.
