The acoustic damping article according to claim 1, wherein the acoustic damping composition has a ratio of coverage of the acoustic damping composition on a first major surface of the release liner of at least about 0.1. 4. The acoustic damping article according to claim 3, wherein the ratio of coverage of the damping composition on the first major surface of the release liner is not greater than about 0.9. 5. The acoustic damping article according to claim 1, wherein the acoustic damping composition forms a pattern. 6. The acoustic damping article according to claim 5, wherein the pattern includes of a rectangle, a square, a triangle, a pentagon, a hexagon, a circle, a circular section, a ring, a half ring, or any combination thereof. 7. The acoustic damping article according to claim 5, wherein the damping composition forms a pattern of stripes. 8. The acoustic damping article according to claim 7, wherein the damping composition forms a pattern of rectangular stripes, wavy stripes, zig-zag stripes, parallel stripes, or a combination thereof. 9. The acoustic damping article according to claim 1, wherein the damping composition comprises a binder resin, wherein the binder resin comprises a urethane component in a water-based emulsion. 10. The acoustic damping article according to claim 9, wherein the binder resin further comprises an acrylic component. 11. The acoustic damping article according to claim 1, further comprising a layer overlying the acoustic damping composition, wherein the layer comprises a wall panel, a ceiling panel, a dry wall, a tile, a subfloor panel, a wood panel, a plywood panel, or a plastic sheet. 12. The acoustic damping article according to claim 1, wherein the release liner comprises polyethylene, polypropylene, polyimide, or any combination thereof. 13. The acoustic damping article according to claim 1, wherein the acoustic damping article has a modal damping factor in the range between 50 to 850 Hz of at least about 10%. 14. The acoustic damping article according to claim 1, wherein the acoustic damping article has a modal damping factor in the range between 700 to 1500 Hz of at least about 10%. 15. The acoustic damping article according to claim 1, wherein the acoustic damping article has a modal damping factor in the range between 1500 to 4000 Hz of at least about 10%. 16.

The construction sheet according to claim 16, wherein the acoustic damping composition forms a pattern. 18. A construction panel comprising: a rigid panel having a first major surface;an acoustic damping composition disposed on the first major surface; anda release liner overlying the acoustic damping composition;wherein the acoustic damping composition has an Interlayer Stiffness of at least about 1 GN/m3; andwherein the acoustic damping article has a modal damping factor in the range between 50to 850 Hz of at least about 10%; wherein the acoustic damping article has a modal damping factor in the range between 700 to 1500 Hz of at least about 10%; and/or wherein the acoustic damping article has a modal damping factor in the range between 1500 to 4000 Hz of at least about 10%. 19. The construction panel according to claim 18, wherein the rigid panel comprises a wall panel, a ceiling panel, a dry wall, a tile, a subfloor panel, a wood panel, a plywood panel, or a plastic sheet. 20. A method of damping a construction wall, the method comprising: applying an acoustic damping article onto a first major surface of a first rigid panel, the acoustic damping article comprising: a release liner, andan acoustic damping composition disposed on the release liner; removing the release liner;applying a second major surface of a second rigid panel onto the acoustic damping composition to form the construction wall;drying the construction wall until the acoustic damping composition has an Interlayer Stiffness of at least about 1 GN/m3; andwherein the acoustic damping article has a modal damping factor in the range between 50to 850 Hz of at least about 10%; wherein the acoustic damping article has a modal damping factor in the range between 700 to 1500 Hz of at least about 10%; and/orwherein the acoustic damping article has a modal damping factor in the range between 1500 to 4000 Hz of at least about 10%. 21. The method according to claim 20, wherein applying the acoustic damping article onto the first major surface includes unwinding the acoustic damping article from a roll. 22. The method according to claim 20, wherein after drying, the acoustic damping composition has a shear modulus G′ of not greater than about 100 MPa at about 1000 Hz and at room temperature.
