Sound Insulation of enclosing Structures in high-rise Buildings. Requirements and Methods of Support

In article questions of providing acoustically comfortable conditions in the high-rise buildings which were widely adopted in the last decades are considered. The main sources of the internal and external noise influencing the population of high-rise buildings are described. Features of mechanisms of transfer of air, shock and structural noise through internal enclosing structures of the building are considered. It is noted that the main way of fight against noise in high-rise buildings is providing appropriate sound insulation with protections of rooms of buildings of air, shock and structural noise. Questions of assessment and rationing of sound insulation are considered. The basic principles of design, calculation procedures and standard technical solutions of sound vibration insulation are given in high-rise buildings. Features of design of floating floors, suspended ceilings, unary and double walls and partitions, ways of strengthening of sound insulation of protections in the existing buildings are in detail considered. Features of isolation of places of communications passage through enclosing structures (pipes of cold and hot water supply, the sewerage, ventilation, etc.) are described. The standard design base for introduction in domestic construction practice of the soundproofing systems providing a combination of effective solutions of tasks of noise reduction to high-quality finishing of rooms on the basis of use of modern sound-proof and sound-absorbing materials is described. The recommendations about providing standard sound insulation of protections provided in article in high-rise buildings will allow to increase quality of the performed project works on sound insulation, to reduce terms and to reduce design cost, to reduce risks of miscalculations at design of sound insulation and to provide finally standard, acoustically favorable conditions of work, accommodation and rest of the population of high-rise buildings.
