Investigation of Methods and Algorithms for Predicting Sound Insulation Characteristics of Prefabricated Enclosing Structures

The traditional method of determining the isolation of air noise of a massive structure is considered, in accordance with SP 23-103-2003 “Design of sound insulation of enclosing structures of residential and public buildings”, in order to substantiate the composition and list of expert and design work to ensure sufficient sound insulation properties of enclosing structures. The relevance of the study is justified by the increase in noise comfort in residential buildings. Enclosing structures made of ceramic porous and aerated concrete blocks plastered with solutions, different in composition and density, were selected as the studied ones. Experimental design work has been carried out: the sound insulation index has been calculated, variable calculations have been performed, and variants of wall structures recommended for further experimental research have been substantiated. Analytical methods were applied, as well as the analysis of the results of theoretical research. The results obtained can be used in the design of residential apartment buildings.
