Resumo
One of the important characteristics of a comfortable environment for a person’s daily stay is the sound insulation of enclosing structures. Insufficient indicators of sound insulation properties of enclosing structures have a negative impact on human health and work activity. To a large extent, both the physical and psychological state of the body is influenced by the level of shock noise. In order to assess these indicators, multiple tests of various floor structures were carried out to ensure that the index of the reduced shock noise level meets the current regulatory requirements. Various variants of structural solutions of overlaps between rooms in buildings of various purposes, which showed the worst values of the indices of the reduced shock noise level, are considered. The analysis of solutions and research presented in various reference and scientific materials and publications of previous years has been carried out. The dependence of the indices of the reduced level of shock noise of the ceilings on the applied design solutions and test conditions is analyzed. The composition of the floor construction layers is described in detail according to the information provided in the design and working documentation for each object of research. Graphs of the relative position of frequency characteristics and estimated spectra of the reduced level of shock noise under overlap for each considered structure are presented.
