Examines the impact of ways of connecting the flexible plate with a space on the soundproofing of enclosing structures during reconstruction, overhaul and operation of buildings with the use of layered vibro-damped elements in comparison with the sheets connected “dry”, with an air gap and filling it with sound-insulating material, with linear and point rigid and vibration-insulated fastening. In large reverberation rooms, experimental studies of the influence of methods of connection of layered vibro-damped elements or sheets connected «dry» on the sound insulation of the main enclosing structure of gypsum tongue-and-groove plates or bricks were carried out. As flexible boards with a space, two gypsum or gypsum-fibre sheets, cement-strand or oriented strand slab of varying thickness bonded by vibration-absorbing material Green Glu or Accent 117 or jointed «dry» were investigated. It is shown that when arranging the air gap between the main structure and the flexible plates with a space it is recommended to arrange linear vibro-damped connections, when filling the air gap with sound-absorbing material – point vibration-insulated connections.
