Meeting Room Acoustic Design in Australia — WELL v2 Feature 74 Requirements
Conference rooms, boardrooms, video conferencing spaces. Typical volume: 30-150 m³.
What WELL v2 Feature 74 Requires for a Meeting Room in Australia
Regulation: WELL v2 Feature 74 Part 1
RT60 target: ≤ 0.6s
Background noise limit: ≤ 35 dBA
STI requirement: ≥ 0.60
How to Calculate WELL v2 Feature 74 Compliance for a Meeting Room in Australia
- 1
Identify the applicable Australia standard and target
Look up WELL v2 Feature 74 for meeting room spaces in Australia. The RT60 target is ≤ 0.6s. WELL v2 Feature 74 Part 1.
- 2
Measure or model the room geometry
Record the length, width, and height of the room to calculate the volume. A typical meeting room has a volume of 30-150 m³.
- 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 WELL v2 Feature 74 and specify treatment
If the calculated RT60 exceeds the target of ≤ 0.6s, specify additional absorption. Typical treatment cost in Australia is AUD 6,000–AUD 13,000.
