In modern construction, one of the main indicators of the quality of housing for users of multi-storey buildings is still noise. The task of preventing the noise that occurs in the house itself needs to be given more attention when designing and soundproofing. It is known that extraneous sounds penetrating into a living space cause a negative impact not only on the psychological state of a person, but also on the physical one. In this regard, each user of the premises wants to receive comfortable conditions for staying in them. To achieve this condition, it is necessary to develop effective structural and technological schemes for soundproofing the floor from impact noise, as well as their verification and evaluation using the theory of planning experiments.
This article is devoted to solving an important issue of sound insulation of floors in monolithic reinforced concrete multi-storey residential buildings, namely from impact noise. The article considers the structural and technological schemes of sound insulation of the floor of fifteen types, using different materials and their combinations to achieve regulatory requirements for sound insulation from impact noise.
It was determined that the thickness of the layer of materials and the density have a significant effect on the insulation performance against shock noise. The work investigated floor constructions based on layers of changing materials. Specifically, such parameters as the thickness (50±10 mm) and density (300±50 kg/m3) of polystyrene concrete "Izolkap" and the thickness of the semi-dry screed (50±10 mm).
When choosing the most rational design and technological scheme used the results of planning theory, as well as indicators of reduced impact noise, obtained as a result of field tests, it allowed to choose the most rational and effective version of "floating" floor ‒ based on materials "Akuflex" and "Izolkap" (polystyrene concrete) ‒ scheme №11, the index of the reduced level of impact noise is Lnw = 52 dB.
The arrangement of the structural and technological scheme of floor sound insulation №11 allows to reduce the level of initial impact noise in the room by 37.5%.
