SOUNDPROOFING DEVICE ON ENCLOSING STRUCTURE AND METHOD OF FIXING SOUND-INSULATING LAYERS ON ENCLOSING STRUCTURE Russian patent published in 2020 - IPC E04B1/84 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to method and device aimed at increasing soundproofing of enclosing structures. Technical result is achieved by the fact that the soundproofing device on the enclosing structure has a profile on the vibration-isolating suspension, at that the sound-insulating and sound-absorbing layers are located one after another with alternation: solid sound-insulating layer, then soft sound-absorbing acoustic damping layer consisting of segments of different density, having high sound absorption coefficient greater than or equal to 0.94, total sound insulation index of all layers is 88–90 dB, and technical result is achieved by a method of fixing soundproof layers of such sound insulation device on enclosing structure.

EFFECT: technical result, for achievement of which the invention is aimed, consists in creation of permanent protective sound-insulating layers and a method of their fixation on enclosing structure.
