What are the specific NCC requirements for sound insulation in new multi-residential buildings in Australia?

The National Construction Code (NCC) Volume One, specifically Section H (formerly F), mandates minimum sound insulation performance for walls and floors separating sole-occupancy units or a sole-occupancy unit from other areas in new multi-residential buildings to safeguard amenity. These requirements, expressed as Weighted Sound Reduction Index (Rw) for airborne sound and Weighted Standardised Impact Sound Pressure Level (Ln,w) for impact sound, typically specify values such as Rw 50 for walls and Rw 50 and Ln,w 62 for floors, to minimise noise transmission.
