Sound -insulating structures based on mineral wool mats or fiberglass canvas reduce the shock noise by a maximum of 10 dB, and only on condition that the protection will be installed not only on the ceiling, but also on the walls. One layer of mats from stone wool on the floor of neighbors on top is able to provide soundproofing 40-60 dB. And the cork canvas is used as a soundproof substrate for a laminate or parquet board.
