ACOUSTIC CABIN Russian patent published in 2018 - IPC E04B1/82 E04H1/12 

FIELD: ground construction.

SUBSTANCE: invention refers to safe means of labor. Acoustic cabin comprises a base, a frame, life support equipment, window and door apertures and enclosures in the form of acoustic panels, with the base installed on at least three pneumatic vibration isolators, made in the form of a rubber-cord shell, and a cabin frame is rigidly fastened thereto in the form of acoustic noise-absorbing panels made in the form of a parallelepiped formed by the front and rear walls of the panel, between which the sound absorber is placed. Front wall is made with glazing made of a noise-reflecting translucent panel, panel from solid plate out of extruded polycarbonate plastic is used as a noise-reflecting translucent element. Cabin is sealed and equipped with life support system composed by artificial microclimate system with a control board, as well as a workstation. Noise-absorber, as an option, is made in the form of a sound-absorbing element comprising a smooth and perforated surfaces between which there is a sound-absorbing structure of a complex shape, which represents an alternation of solid and hollow sections. Moreover, the solid sections, in their turn, are formed by smooth prismatic surfaces fixed to the smooth surface of the wall and two associated prismatic surfaces having on one side a smooth surface, and on the other side - a scalloped surface, wherein the tops of the teeth face inside these surfaces, and the surfaces themselves are fixed on the perforated surface of the sound-absorbing structure, and relief sound-absorbing elements are attached to the smooth surface of the wall, and the cavities of alternating solid sections, as well as the cavity between the scalloped prismatic surfaces, filled with sound-absorbing material.

EFFECT: technical result is increased operator’s work efficiency by reducing the dust and noise levels.
