Currently, the problem of sound insulation in residential buildings is one of the main ones when the project passes the examination. Increased comfort in terms of sound insulation in category A houses is the main one, along with insolation and energy efficiency. Cellular concrete composite materials are widely used, often used in the construction of residential prefabricated buildings as a construction of wall filling and partitions, as well as walls between apartments and stairwell-elevator halls, but their sound insulation is little studied and is not a value fixed when releasing small wall stones. The paper proposes the principles of calculating the sound insulation of small wall stones made of cellular concrete with a commercial density of 500 and 600 kg/m3 with options for interior finishing in the form of grout or plastering. At the same time, the thicknesses of these layers varied from 2 to 10 mm. The results of the calculations gave a good convergence, confirmed by laboratory studies. The variants of performing calculations of sound insulation of partitions made of cellular concrete small wall stones with the use of commercial plaster compositions made of cement-sand and lime-sand mortar are presented.The above methods for calculating the air noise insulation index provide good convergence with the results of laboratory studies, which can be used in the future when predicting the air noise insulation index for new modern wall materials that are at the testing stage.
