A noise control flooring system is presented herein for reducing noise transmission in a building structure that contains the system. The system comprises a solid substrate layer, a compressible layer overlying at least a portion of the substrate layer, and an entangled net layer that overlies at least a portion of the compressible layer, wherein the net layer is comprised of multiple polymer filaments and air, together forming a void space. A separation layer overlies at least a portion of the entangled net layer. The separation layer carries a floating solid substrate layer thereupon. This solid substrate layer provides loading for causing the compressible layer to compress into the overlying entangled net layer.
