The article presents the results of studies on the influence of foam concrete density depending on the thickness of the material on the airborne noise insulation index. It has been established that the most effective option is to use not heavy concrete, but light concrete with a density of 900-1100 kg/m3. With a partition thickness of 8 cm, the internal partition between rooms for houses of all categories provides effective noise protection, and with a partition thickness of 10 cm, the required value of the sound insulation index is achieved between the bathroom and the room of one apartment. The required degree of noise protection for walls and partitions between apartments, between rooms of apartments and staircases, halls, corridors, lobbies for houses of category “B” is achieved with a wall thickness of 12 cm, houses of category “B” - 14 cm and houses of category “A” - 16 cm.
