METHOD OF SOUND INSULATION OF KOCHETOV'S EQUIPMENT AND SOUND-INSULATING FENCING Russian patent published in 2017 - IPC B27B5/38 

FIELD: machine engineering.

SUBSTANCE: method of soundproofing equipment, consisting in the fact that a soundproof enclosure is installed on the floor of a building by means of vibration-proof supports made of elastic material. Sound-insulating fencing is made in the form of a rectangular parallelepiped with a cut-out in its lower face under the base of the technological equipment. The base of the process equipment is installed on the vibration isolating supports, which are based on the ceiling of the building. Between the base of the process equipment and the cutout in the lower face of the rectangular parallelepiped, a gap is made to prevent the transfer of vibrations from the process equipment to the soundproof enclosure in which ventilation channels are performed to eliminate equipment overheating. The internal walls of the ventilation ducts are treated with a sound-absorbing material and an acoustically transparent material. The sound-absorbing element is fixed to the inner surface of the sound-insulating fence and is made in the form of a smooth and perforated surface between which a multi-layered sound-absorbing structure is placed. To implement the claimed method, a soundproof enclosure is used.

EFFECT: increased efficiency of sound suppression.
