Methods for rating the sound insulation in buildings and of building elements - Method for rating the airborne sound insulation of façade elements and façades Ingestion-build-201039 recommendations are made for attenuation1 Scope and field of application This part of ISO 717 defines single number quantities for the airborne sound insulation of faades, faade elements, windows, doors, roofs, and gives rules for determining these quantities from the results of measurements carried out in one third octave bands according to ISO 140 3 and ISO 140 5. The single number quantities according to this part of ISO 717 are intended for rating the airborne sound insulation and for
