During operation, reconstruction, and overhaul of buildings, it may be necessary to increase the sound insulation of existing fences to current regulatory values. One of the ways to improve sound insulation is the installation of a flexible plate with respect to the building envelope. Sound insulation of this design is influenced by various factors. In this work, we study experimentally the effect of a flexible plate on a relate of various sheet materials (gypsum board, cement particle board, oriented strand board) of various thicknesses, connected «dry» and in the form of layered vibration damped elements, with an air gap and filling it with sound-absorbing material. The acoustic efficiency of the studied structural solutions for the main structure of gypsum tongue-and-groove blocks and a plastered brick partition is shown. The effect on sound insulation is noted: surface density characteristics; there is an air gap and sound accompaniment; methods of connecting layers in the construction of flexible plates in the form of sheets, connecting «dry» and in the form of layered vibration damped elements from various sheet materials. It has been established that the ratio of the surface densities of the main structure and the flexible slabs on the relate significantly affects the amount of additional sound insulation, with an increase in the surface density of the flexible slab on the base with the invariable main structure, the additional sound insulation increases. It is shown that the use of flexible slabs in the relative form in the form of layered vibrodamped elements compared with sheets connected «dry» increase the sound insulation by 2–3 dB. With an increase in the surface density of the main structure, the effect of vibration absorption decreases.
