[Current]Acoustics - Rating of sound insulation in buildings and of building elements, Part 2: Impact sound insulation
AS ISO 717.2:2024 identically adopts ISO 717 2:2020, which provides a method whereby the frequency dependent values of impact sound insulation of building elements and in buildings (from both laboratory and field measurements) can be converted into a single number to characterize the acoustical performance
