Abstract

Sound-permeable lining (1) for covering perforations (21) shaped in an acoustic plasterboard (2). The sound-permeable lining (1) comprises a first ply (12) of a fleece material and attached thereto a second ply (14) which is arranged in between of the first ply (12) and the acoustic plasterboard (2) to which the sound-permeable lining (1) is to be applied. The second ply (14) being of a foil material having a second opacity O2 and a plurality of through-holes (141) formed therein. The first ply (12) has a first opacity O1 so that the through-holes (141) formed in the second ply (14) are invisible through the first ply (12) and so that the applied sound-permeable lining (1) has an overall opacity O12 to allow for optically covering the perforations (21) shaped in the acoustic plasterboard (2) and an overall air flow resistivity Rs12 to allow for the penetration of air so that sound can propagate via the sound-permeable lining (1).
