An acoustic damping article includes a substrate, wherein the substrate has a surface area S. The acoustic composition further includes a polymer resin. The polymer resin coats partially the surface area with a set of areas. The ratio of the coated areas over the surface area S is less than 1 and the polymer resin coverage is not greater than about 500 g/m.sup.2. Embodiments of the present disclosure include an acoustic damping article including a release liner; and an acoustic damping composition disposed on the release liner. The acoustic damping composition partially coats the release liner, and the acoustic damping composition has a Patterned Interlayer Stiffness of at least about 1 GN/m.sup.3.
