In the era of technological progress, much attention is paid to such a problem as noise, the long-term impact of which has a negative impact on the human body. It is noted that the walls of residential buildings erected from blocks based on light concrete and not only do not always meet the necessary requirements for sound insulation. Therefore, this paper considers the effectiveness of using concrete blocks with non-removable tubular voids, as partitions, for noise insulation in residential buildings. The calculation was made to determine the calculated values of the air noise insulation index for model samples of blocks and blocks of standard sizes. A comparison with the nearest analogues is given. At the end, the main conclusions are presented, based on the results of calculating the noise insulation properties of the studied blocks, comparing them with regulatory requirements and analogues.
