Subject: an important task in the design of internal enclosing structures of apartments is the establishment of their required soundproofing ability. At present, there is no reliable method for determining the required sound insulation and in this regard internal enclosures are designed without proper justification for noise protection. Research objectives: development of a technique for determining the required sound insulation of apartment’s internal enclosures to ensure an acceptable noise regime in the apartments’ rooms under the action of intra-apartment noise sources. Materials and methods: the methodology was developed on the basis of a statistical method for noise calculation in the apartments, treated as systems of acoustically coupled proportionate rooms, and with the help of a computer program that implements this method. Results: the technique makes it possible to generate, with the use of computer technologies, a targeted selection of internal enclosures of the apartment to meet their soundproofing requirements. Conclusions: the technique proposed in the article can be used at the design stage of apartments when determining the required soundproofing of partitions and doors. Using this technique, it is possible to harmonize the sound insulation ratio of individual elements among themselves and thereby guarantee a selection of internal structures for their acoustic and economic efficiency.
