ACOUSTIC CABIN OF COMPRESSOR PLANT OPERATOR Russian patent published in 2011 - IPC E04B1/82 

FIELD: construction.

SUBSTANCE: acoustic cabin of a compressor plant operator comprises a base, a frame, window and door openings and barriers in the form of acoustic panels. The base is installed onto at least three pneumatic vibration isolators, arranged in the form of a rubber-cord casing. The cabin frame, made as a polyhedral prism with ribs perpendicular to the cabin base, is rigidly fixed to it. The frame comprises the front wall with glasing made of a noise-reflecting light transparent panel, a ceiling part with lamps, a back wall arranged in a plane, parallel to the plane of the front wall, and four side walls, in one of which a door is installed. The area of the back wall is at least twice more than the area of the front wall. Side walls adjacent to the front wall are arranged as inclined relative to it and with glasing. Those adjacent to the back wall are perpendicular to it. The cabin is tight and is equipped with a system of life support in the form of an artificial microclimate system with a control panel, and also a workplace, which comprises a working table, a chair with vibration isolators in the form of elastomer plates attached to the chair legs, and a peg for a change of clothes.

EFFECT: invention makes it possible to increase efficiency of noise damping by increasing coefficient of sound absorption through larger surfaces of sound absorption with preservation of the cabin dimensions.
