METHOD FOR SOUND INSULATION AND SOUND-INSULATING ELEMENT THEREFOR Russian patent published in 2016 - IPC E04B1/00 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used for sound insulation of barrier structures. High sound insulation is achieved by sound insulation, which includes fixation of protective layer of sound-insulating elements on enclosure, wherein one cavity is formed by permanent connection with a gap sound-insulating elements to enclosure, and second cavity is formed inside sound-insulating elements, which is filled with sound-reflecting and sound-absorbing materials. Method enables to simultaneously use both sound-reflecting, and sound-absorbing materials. Continuous uniform distribution of said materials relative to entire protected surface of enclosure increases degree of sound insulation.

EFFECT: high sound insulation.
