Local note: Sydney and Melbourne studio scene growing with streaming content.
How to Calculate ISO 3382 Compliance for a Recording Studio in Australia
- 1
Identify the applicable Australia standard and target
Look up ISO 3382 for recording studio spaces in Australia. The RT60 target is 0.3–0.5s. ISO 3382-1 — measurement reference.
- 2
Measure or model the room geometry
Record the length, width, and height of the room to calculate the volume. A typical recording studio has a volume of 20-200 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 ISO 3382 and specify treatment
If the calculated RT60 exceeds the target of 0.3–0.5s, specify additional absorption. Typical treatment cost in Australia is AUD 450–AUD 800/m².

Frequently Asked Questions
What RT60 does ISO 3382 require for a recording studio in Australia?
ISO 3382 requires a reverberation time of 0.3–0.5s for recording studio spaces in Australia. ISO 3382-1 — measurement reference. Measurement should be performed per ISO 3382-2 methodology.
What is the background noise limit for a recording studio in Australia?
The background noise limit is NR-15 under ISO 3382. This typically refers to HVAC and building services noise measured with the room unoccupied.
How much does acoustic treatment cost for a recording studio in Australia?
Typical acoustic treatment for a recording studio in Australia costs AUD 450–AUD 800/m². Costs vary based on finish quality, room size, and existing conditions.
