2.

AS/NZS 2107:2016 provides recommended design sound levels and reverberation times for occupied spaces

State EPA guidelines (e.g., NSW EPA INP) set environmental noise criteria for developments near noise sources

4.

Green Star Design & As Built v1.3 requires acoustic assessment for Interior Environment credits

Green Building Certifications

These voluntary certifications include acoustic performance credits and are increasingly the market standard for premium Australia developments.

Common Mistakes by Australia Architects

!

Relying on NCC deemed-to-satisfy (DTS) solutions without verifying flanking transmission — NCC DTS assumes ideal construction which rarely occurs

!

Not accounting for the difference between laboratory Rw ratings and field-measured DnT,w values — typically 5-8 dB reduction in the field

!

Overlooking mechanical noise from HVAC systems in AS/NZS 2107 compliance — many Australian buildings exceed background noise targets due to AC systems sized for extreme heat

City-Level Acoustic Guides in Australia

City of Melbourne Planning Scheme Clause 58 (Better Apartments) includes specific acoustic standards for apartment developments.

Frequently Asked Questions: Australia Acoustics

Is AS/NZS 2107 mandatory in Australia?▾
AS/NZS 2107:2016 is not directly mandatory under the NCC but is referenced by Green Star, WELL, and many local planning requirements. It provides recommended design sound levels for 78 room types. The NCC Section F5 is the mandatory standard for sound insulation in residential buildings (Class 2-4), while AS/NZS 2107 guides the acoustic design of the spaces themselves.
What does NCC Section F5 require?▾
NCC 2022 Section F5 requires minimum airborne sound insulation of Rw + Ctr >= 50 for walls and Rw + Ctr >= 50 for floors between sole-occupancy units. Impact sound insulation must achieve Ln,w <= 62 for floors. These can be met via DTS solutions (specified constructions) or Performance Solutions (verified by testing or modelling).
How does Green Star assess acoustics?▾
Green Star Design & As Built v1.3 IEQ-11 awards up to 3 points for acoustic comfort. It requires internal noise levels per AS/NZS 2107 (2 points) and reverberation time compliance per AS/NZS 2107 (1 point). An acoustic consultant report is required as evidence. The v1.3 tool also references WELL v2 acoustic criteria.
Do I need acoustic testing in Australia?▾
Pre-completion acoustic testing is not universally mandated by the NCC but is increasingly required by certification bodies (Green Star, WELL) and many local councils. NSW SEPP 65 and the Apartment Design Guide require verification of acoustic performance for residential flat buildings. Most acoustic consultants recommend testing for compliance evidence.
