Open Plan Office Acoustic Design in Australia — AS/NZS 2107:2016 Requirements
Open plan workspaces, trading floors, collaborative offices. Typical volume: 500-5,000 m².
What AS/NZS 2107:2016 Requires for a Open Plan Office in Australia
Regulation: AS/NZS 2107:2016
RT60 target: ≤ 0.8s
Background noise limit: 40–45 dBA
Local note: Baseline standard for office acoustics in Australian market.
How to Calculate AS/NZS 2107:2016 Compliance for a Open Plan Office in Australia
- 1
Identify the applicable Australia standard and target
Look up AS/NZS 2107:2016 for open plan office spaces in Australia. The RT60 target is ≤ 0.8s. AS/NZS 2107:2016.
- 2
Measure or model the room geometry
Record the length, width, and height of the room to calculate the volume. A typical open plan office has a volume of 500-5,000 m².
- 3
List all surfaces and their absorption coefficients
For each surface (floor, ceiling, walls, windows, doors), find the absorption coefficient at each octave band frequency (125 Hz to 4 kHz) from ISO 354 test data or a materials database.
- 4
Calculate total absorption and apply the Sabine or Eyring equation
Sum all surface absorption values: A = sum of (alpha x area). Then apply T60 = 0.161 x V / A (Sabine) or T60 = -0.161 x V / (S x ln(1 - alpha_avg)) (Eyring). Use Eyring when average alpha exceeds 0.20.
- 5
Compare result against AS/NZS 2107:2016 and specify treatment
If the calculated RT60 exceeds the target of ≤ 0.8s, specify additional absorption. Typical treatment cost in Australia is AUD 100–AUD 180/m².
