Abstract
The present disclosure describes a sound attenuating flooring system. The sound attenuating flooring system has a subfloor, a sound attenuating material overlaying and contacting only a portion of the subfloor, and an overlayment. The sound attenuating material has a first surface and second surface. The first surface is defined by a plurality of outwardly projecting hollow protrusions. The second surface is defined by a plurality of open recesses corresponding to the plurality of outwardly projecting hollow protrusions. The overlayment overlays the second surface of the sound attenuating material.
Claims26
A sound attenuating flooring system comprising:
- a subfloor;
- a sound attenuating material overlaying the subfloor, the sound attenuating material having a first surface and a second surface, the first surface defined by a plurality of outwardly projecting hollow protrusions, each protrusion has a tip, the tip carries a vibration dampening reactive material, said vibration dampening reactive material on the tip of the outwardly projecting hollow protrusions in direct contact with said subfloor, and the second surface defined by a plurality of open recesses corresponding to the plurality of outwardly projecting hollow protrusions;
- and
- an overlayment overlaying the second surface of the sound attenuating material.
A sound attenuating flooring system comprising:
- the sound attenuating flooring system incorporated into an above-ground flooring system;
- a subfloor;
- an underlayment in direct contact with said subfloor;
- a sound attenuating material having a first surface and a second surface, the first surface defined by 4 outwardly projecting hollow protrusions to 50 outwardly projecting hollow protrusions per square inch, each protrusion has a tip, the tip carries a vibration dampening reactive material, said vibration dampening reactive material on the tip of the outwardly projecting hollow protrusions directly contacting said underlayment, and the second surface defined by a plurality of open recesses corresponding to said outwardly projecting hollow protrusions;
- and
- an overlayment overlaying the second surface of the sound attenuating material, said overlayment having a thickness between about 0.25 inch and about 0.7 inch.
