Patent ID: 8146310

Claim:
A noise control flooring system that reduces noise transmission in a building structure containing the system and which comprises: a solid substrate layer; a compressible layer overlying at least a portion of said substrate layer, the compressible layer comprising a high-loft nonwoven fabric, wherein the weight of the fabric is between 50 gsm and 200 gsm, and the fabric is compressible from an initial thickness of between 0.125 in (0.318 cm) and 0.626 in (1.590 cm) to a compressed thickness of about 0.05 in (0.125 cm); a void space creating device overlying at least a portion of said compressible layer; and a separation layer that overlies at least a portion of said void space creating device and which separation layer serves to carry a floating solid substrate layer thereupon and which provides loading for causing said compressible layer to compress into said overlying device, wherein the compressible layer at least partially fills a void space of the overlying void space creating device.
