1. A floor assembly, comprising: a sub-flooring layer;a top-flooring layer overlying the sub-flooring layer; anda sound control mat positioned between the sub-flooring layer and the top-flooring layer, the sound control mat comprising: a resilient layer of extruded polymer monofilaments, the polymer
1. A floor assembly, comprising: a sub-flooring layer;a top-flooring layer overlying the sub-flooring layer; anda sound control mat positioned between the sub-flooring layer and the top-flooring layer, the sound control mat comprising: a resilient layer of extruded polymer monofilaments, the polymer monofilaments being heat welded at junctions to form a matrix of tangled monofilaments, the resilient layer having a machine direction and a cross-direction, the resilient layer comprising a plurality of waves forming a repeating pattern of peaks and valleys, the waves extending in the machine direction and the cross-direction, each wave having a pair of legs, each leg extending from the peak of the wave to an adjacent valley, the average ratio of the width of the waves, as measured in the cross-direction, to the length of the waves, as measured in the machine direction, being at least about 2:1; anda fiberglass scrim bonded to the resilient layer at the valleys of the waves, the scrim comprising a plurality of fiberglass strands, the fiberglass strands comprising two sets of strands, the strands in one set of strands intersecting the strands in the other set of strands at angles of about 90°, the fiberglass scrim further comprising a water or moisture impermeable polymer coating extending between the two sets of strands;the resilient layer contacting the sub-flooring layer at the peak of the waves, the scrim contacting the top-flooring layer,wherein the peaks of the waves are configured to at least partially compress upon application of an impacting force to the top-flooring layer and recover their pre-compressed shape upon release of the impacting force. 2. The floor assembly of claim 1 wherein the polymer monofilaments have an average diameter in the range from about 1 to about 4 mils. 3. The floor assembly of claim 1 wherein the thickness of the resilient layer has a major dimension in the range from about 0.1 to about 1 inch, and a minor dimension in the range from about 0.01 to about 0.04 inch. 4. The floor assembly of claim 1 wherein the mat has a porosity level in the range from about 75 to about 98 percent. 5. The floor assembly of claim 1 wherein the resilient layer comprises from about 25 to about 400 polymer monofilaments per foot as measured in the cross direction. 6. The floor assembly of claim 1 wherein the polymer monofilaments are made of a material comprising polyolefin, polyamide, polyester, polyvinylchloride, or a mixture of two or more thereof. 7. The floor assembly of claim 1 wherein the polymer monofilaments are made of a material comprising polyethylene, polypropylene, or a mixture thereof. 8. The floor assembly of claim 1 wherein the strands in one set of strands are aligned parallel to each other and extend lengthwise in the machine direction, and the strands in the other set of strands are aligned parallel to each other and extend in the cross-direction. 9. The floor assembly of claim 8 wherein the number of strands extending in the machine direction is in the range from about 1 to about 20 per inch of scrim as measured in the cross-direction; and the number of strands extending in the cross-direction is in the range from about 1 to about 20 per inch of scrim as measured in the machine direction. 10. The floor assembly of claim 1 wherein the fiberglass strands comprise a plurality of filaments. 11. The floor assembly of claim 1 wherein the fiberglass strands are made of a plurality of filaments, the filaments comprising fiberglass filaments and optionally polyester filaments. 12. The floor assembly of claim 1 wherein the polymer coating comprises a polyolefin, polyvinyl alcohol, polyvinyl chloride, polyacrylate, styrene-butadiene rubber, or a mixture of two or more thereof. 13. The floor assembly of claim 1 wherein the fiberglass scrim comprises a polymer coating for binding the fiberglass strands, the polymer coating being derived from a polyvinyl chloride plastisol. 14. The floor assembly of claim 1 wherein the scrim has a thickness in the range from about 0.5 to about 1.5 mils. 15. The floor assembly of claim 1 wherein the mat has a weight in the range from about 1 to about 5 ounces per square foot. 16. The floor assembly of claim 1 wherein the mat is in the form of a roll. 17. The floor assembly of claim 1 wherein the average ratio of the width of each wave, as measured in the cross-direction, to the length of each wave, as measured in the machine direction, is at least about 10:1. 18. The floor assembly of claim 1 wherein the top-flooring layer comprises a poured floor, and at least part of the scrim is embedded in the top-flooring layer.
