Comparative analysis of Russian, foreign, and international regulatory requirements for airborne sound insulation in civil buildings

Introduction. The impact of indoor noise on human health has been confirmed by systematic reviews and recognized as a risk factor by WHO. Existing comparative studies have predominantly focused on European contexts and have not incorporated criteria from green building certification systems. This paper presents a comparative analysis of regulatory requirements for airborne sound insulation of internal building partitions in 43 countries, along with acoustic criteria of WELL, BREEAM, and LEED. Materials and methods. A mathematical conversion of national sound insulation indices was performed, reducing them to a unified equivalent in-situ index R′ w based on generalized relationships from ISO/FDIS 19488. Results. At least seven distinct regulatory indices are used globally. For inter-apartment partitions, the median R′ w was 52 dB (range: 43–58 dB), with the Russian standard ( R′ w ≥ 50 dB) falling within the median range. The Russian regulatory framework features a deeper typological classification compared to WELL, BREEAM, and LEED. Conclusions. At least seven distinct regulatory indices are used globally. For inter-apartment partitions, the median R′ w was 52 dB (range: 43–58 dB), with the Russian standard ( R′ w ≥ 50 dB) falling within the median range. The Russian regulatory framework features a deeper typological classification compared to WELL, BREEAM, and LEED.
