WORKSHOP ACOUSTIC STRUCTURE Russian patent published in 2018 - IPC E04B1/84 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular to the production rooms acoustic structure, for example of a workshop. Production rooms acoustic structure contains the workshop frame, bearing walls with enclosures in the form of a floor and a ceiling, which are lined with sound-absorbing structures, window and door openings, as well as single sound absorbers, containing a frame, in which the sound-absorbing material is arranged. Floor is made on elastic base and includes mounting plate, made of concrete reinforced by vibration damping material, which is installed on base plate of inter-floor slab with cavities through the layers of vibration damping material and waterproofing material with clearance relative to bearing walls of production room, wherein cavities of the base plate are filled with a vibration damping material, for example, foamed polymer. Sound-absorbing structure is made in the form of rigid and perforated walls, between which two layers are arranged: sound-reflecting layer, adjacent to rigid wall, and sound-absorbing layer, adjoining perforated wall.

EFFECT: technical result is the noise suppression increased efficiency.
