| Abstract | The standard, ISO 12354 requires that for each flanking transmission path involved in the calculation of the apparent transmission loss, the sound reduction index of the involved elements should relate to the resonant transmission only. The Standard indicates that the calculation of the resonant transmission should be made using the radiation efficiencies measured with airborne and structure-bore excitation. The Standard indicates that for double leaf elements, the difference between the resonant and measured transmission loss is small but is this true in practice? And what is the consequence of not calculating the resonant transmission loss correctly? Data is presented which compares calculations of flanking transmission for individual flanking paths using data measured for individual elements and junctions with measurements of flanking transmission for identical constructions in the eight room flanking facility at the National Research Council Canada to determine the importance of the calculation of the resonant transmission loss. |
