KOCHETOV LOW-NOISE ASEISMIC PRODUCTION BUILDING Russian patent published in 2018 - IPC E04B1/84 E04H9/02 

FIELD: acoustics.

SUBSTANCE: invention relates to industrial acoustics. In the low-noise seismic resistant production building containing the building frame with foundation, bearing walls with enclosures of floor and ceiling, which are lined with sound-absorbing structures, window and door openings, as well as piece sound absorbers, containing a frame in which the sound-absorbing material is located, and installed above the noisy equipment, in their fixation points to the building bearing walls the roofing basic load-bearing slabs are equipped with the spatial vibration isolation system consisting of horizontally located vibration isolators, accepting vertical static and dynamic loads, as well as vertically located vibration isolators accepting horizontal static and dynamic loads, at that, the floor in the rooms is made on the elastic foundation and contains made of reinforced with the vibration damping material concrete installation plate, which is installed on the inter-floor overlapping base plate with the cavities through the vibration cushioning material and waterproofing material layers with a gap relative to the production room bearing walls, wherein the base plate cavities are filled with the vibration damping material, for example, foamed polymer, acoustic enclosures are made in the form of rigid and perforated walls, between which layers of sound-reflecting, as well as sound-absorbing materials of different density are located arranged in two layers, and the layers of the sound reflecting material are made of a complex profile consisting of uniformly distributed hollow tetrahedrons that allow to reflect the sound waves falling in all directions and which are located respectively at the rigid and perforated walls, at that, the sound-reflecting material layers are made from heat-insulating material able to maintain preset microclimate in the room.

EFFECT: higher efficiency of noise suppression.
