Abstract
The new Spanish regulation about sound insulation in buildings (DB HR) laid the foundations for calculating the acoustic performance of dwellings by means of a method which stems from the simplified method of the European norm UNE 12354-1:2000. The input variables of this method are not only the acoustic characteristics of the elements, but also the dimensions and geometrical settings of each couple of rooms. There is a widespread belief that the worst case is covered if it is considered that both rooms have their four edges coincident. This supposition, which simplifies conveniently the large amount of case studies, is generally incorrect and, in some cases, it has important consequences in the sound insulation final result. Along this text the more usual case studies are presented, including some cases presenting two partition walls which have not been included yet in the official data sheets. Some of the consequences of accepting the symmetry assumption are also analysed.
