Abstract. The main problems of combating air and impact noise during the delivery of apartments with free planning are given. Special attention is paid to the control of noise levels in rooms of different types when putting the house into operation. The main attention is paid to the “floating floors”, the device which greatly increases the insulation. The impact noise of the inter­apartment floor is 6 m, the composition of such floor is indicated, indicating the main insulating materials and their characteristics.
Key words: Air noise, impact noise, insulation, floating.
