ACOUSTIC CABIN BY KOCHETOV Russian patent published in 2015 - IPC E04B1/84 

FIELD: machine building.

SUBSTANCE: invention relates to safe working facilities. An acoustic cabin comprises a base, a frame, life support equipment, window and door apertures and enclosures in the form of acoustic panels. The base is mounted on at least three pneumatic vibration isolators made as a rubber cord shell, and a cabin frame in the form of acoustic sound absorbing panels of parallelepiped shape is rigidly attached to the base, the parallelepiped is formed by the front and back walls of the panel with sound absorbing material placed in-between. Each wall is of U-shape. Slot perforation is made on the front wall and its perforation coefficient is equal to or exceeds 0.25. The front wall is glazed by sound reflecting translucent panel made as a polygon, for example, a rectangle, formed by U-shape ribs made from vibration damping material. A panel from solid plate out of extruded polycarbonate plastic is used as the sound reflecting translucent element. The frame also consists of a ceiling with luminaries, a back wall placed in the plane parallel to the front wall plane, and four side walls with a door provided in one of them. The area of the back wall is by at least 2 times greater than the area of the front wall, and side walls adjoining the front wall are inclined to it and glazed, and those adjoining the back wall are perpendicular to it. The cabin is leakproof and is equipped by a life support system in the form of an artificially maintained environment system with a control panel, for example, a cartridge conditioner produced by General Climate. Operator's workstation is equipped by a work table and a chair with vibration isolators in the form of elastomer plates attached to the chair legs. "Vibroflex EP/25A" type or "VEP" type vibration damping plates are used as the above elastomer.

EFFECT: invention allows for increased operator's work efficiency due to decreased levels of dust and noise.
