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

A gypsum board comprises linings made of coated non-woven fiberglass mats having surfaces turned away from the gypsum core of the fiberglass mats which have been coated with an inorganic binder at least partially set with water. Preferably, quick-setting mixtures comprising cement, .alpha.-hemihydrate and ultra-fine silica are used which are dimensionally stable during setting as well as later on.
