The floor is made on an elastic base and comprises a base plate made of concrete reinforced with vibration damping material and installed on a basic plate of a floor slab with cavities via layers of vibration damping material and hydraulic insulation material installed with a gap relative to bearing walls of a production room. Cavities of the basic plate are filled with vibration damping material, for instance, with a foamed polymer. On the walls there are noiseproof panels, every of which comprises a face wall made of glass tissue, a rear wall, upper, lower and side walls made of steel, fastening strips for fixation of glass tissue, an aluminium angle, fixing elements. Inside the external lining there is a sound-absorbing material. ^ EFFECT: invention makes it possible to improve efficiency of noise attenuation. ^ 5 cl, 4 dwg |
