The ATS board is a more economical, yet exact substitute for Owens Corning 703 2" Sound absorption, appearance, and physical properties are virtually identical. The only differences are: 1) this material is slightly lighter in color than 703, and 2) it is somewhat softer, that is it compresses somewhat more easily than OC 703.
These insulation boards are a popular product in sound absorption projects. Typically, they are covered with fabric and mounted on the walls in a studio, control room, or listening room.
