    • 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 O 2 and a plurality of through-holes (141) formed therein. The first ply (12) has a first opacity O 1 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 Ο 12 to allow for optically covering the perforations (21) shaped in the acoustic plasterboard (2) and an overall air flow resistivity R s12 to allow for the penetration of air so that sound can propagate via the sound-permeable lining (1).
    • 用于覆盖在石膏板(2)中成形的穿孔(21)的透声衬里(1)。 透声衬里(1)包括一个羊毛材料的第一层(12),并附着在第二层(14)上,第二层(14)布置在第一层(12)和声石膏板(2)之间, 应采用透声衬里(1)。 第二层(14)是具有第二不透明度O 2的箔材料和形成在其中的多个通孔(141)。 第一层(12)具有第一不透明度O1,使得形成在第二层(14)中的通孔(141)通过第一层(12)不可见,并且所施加的透声衬里(1)具有 整体不透明度Ο12以允许光学地覆盖形成在声学石膏板(2)中的穿孔(21)和总体气流阻力Rs12以允许空气渗透,使得声音可以经由透声衬里(1)传播, 。
