AbstractThe two standard methods for rating the impact sound insulation of building components (ISO 717-2 [1] and ASTM E989 [2]) produce Ln,w (normalized weighted impact sound index) and IIC (impact insulation class). ISO 717 also proposes two spectrum adaptation terms to be used in addition to Ln,w. These four ratings can give quite different rankings when applied to the same set of test results. When they are applied to evaluate floor toppings, especially on lightweight joist floors, contradictions become even greater. Standard writing committees need to remove the confusion caused by the existence of these different rating methods.
