Abstract
An air-borne sound insulating arrangement with absorption properties for surface elements, in particular for partition walls in motor vehicles, comprises a heavy layer which has foam layers on both sides which have skins on the outside or have a foil as a covering. The arrangement is arranged so close to the surface element (sheet 1) to be protected that the distance between the heavy layer and the surface element is as small as possible. Adhesion to the surface element does not take place. The arrangement can rest against the surface element or can be at a short distance therefrom so as to even out corrugations or the like. The arrangement is arranged in the desired position in relation to the surface element by means of fastening bolts and/or fastenings at the edges.
