Calculation of sound insulation according to EN 12354: Influence of sound reduction index of flanking elements

摘要

EN 12354 standards describe models for calculation of sound insulation in buildings. EN 12354-1 defines a model for airborne sound insulation, while EN 12354-2 describes the calculation procedure for impact sound insulation. Although the calculated value of sound insulation in both cases depends mostly on the insulation properties of the separating element, flanking transmission is also treated. The aim of this work is to assess the influence of sound reduction index of flanking elements (walls, floors and ceilings) on the calculated value of airborne and impact sound insulation.
