FIELD: construction; acoustics.
SUBSTANCE: invention relates to multilayer finishing sound absorbing materials and refers sound absorbing wall covering. Includes: (a) support layer made of organic polymer foam material, which open porosity makes 0.50–0.995, (b) surface layer made of glass-fabric material, which static resistance to air flow, measured according to ISO 9053 standard, ranges from 105 H•c•m-4 up to 106 H•c•m-4 and (c) intermittent adhesive layer, which surface density makes from 17 to 60 g/m2, at boundary between support layer (a) and surface layer (b). Invention also relates to said coating making method and to use of such coating for improvement of room or building acoustic comfort.
EFFECT: invention provides creating wall coating, which provides acoustic comfort, id est reduction and optimization of reflected sound component.
