FIELD: acoustics.
SUBSTANCE: invention relates to the equipment sound insulation with broadband acoustic suppression means, and can be used in all sectors of the national economy as the noise protection means. Soundproofing enclosure is made in the form of covering the process equipment rectangular parallelepiped, process equipment is installed on at least four vibration-proof supports, which are based on the building floor slab, at that, between the process equipment base and the cutout in the rectangular parallelepiped lower face a gap is made, designed to eliminate the vibrations transfer from the process equipment to the soundproof enclosure, wherein in order to eliminate the equipment overheating, in the soundproof enclosure the ventilation ducts are made, at that, the ventilation ducts internal walls are treated with a sound-absorbing material and an acoustically transparent material of the “Poviden” type, at that, on the soundproofing enclosure inner surface sound-absorbing element is fixed, made in the form of rigid and perforated walls, between which the multi-layer sound-absorbing element is arranged, which is made in the form of two layers: one of which, adjacent to the rigid wall, is sound-absorbing, and the other, adjacent to the perforated wall, is made with perforation from the complex shaped sound-reflecting material, at that, as the sound-absorbing material, the aluminum-containing alloys based material is used, with their subsequent filling with titanium hydride or air, at that, the vibration isolation system vibration isolator, on which the building's floor slab based process equipment is installed, comprises housing and elastic element from elastomer, for example, rubber, housing is made in the form of supporting elements containing washers, bolts and nuts, located coaxially and oppositely to the elastic element in its upper and lower parts, made in the form of elastomeric shell, consisting of flat mounting surfaces, on which the supporting elements are fixed, and also cylindrical surface, located in the central perpendicular section relative to the support elements axes, and conical surfaces, located between the mounting surfaces and the cylindrical surface, and coupled with them into the single shell.
EFFECT: technical result is the increased efficiency of noise suppression.
