What ISO 3382 Requires for a Home Studio

RT60 (Reverberation Time)
The time, in seconds, for sound to decay by 60 dB after the source stops. ISO 3382 requires 0.2-0.4s (voice/podcast) | 0.3-0.5s (music recording) for home studio spaces.
Reference: ISO 3382-2:2008 (measurement reference)

Clause reference: ISO 3382-2:2008 (measurement reference)

RT60 target: 0.2-0.4s (voice/podcast) | 0.3-0.5s (music recording)

Background noise limit: NR-15 (recording) | NR-25 (mixing)

Measurement condition: Treated, unoccupied

Note: No mandatory standard. ISO 3382 used as measurement protocol.

How to Calculate ISO 3382 Compliance for a Home Studio

  1. 1

    Identify the applicable standard and target

    Look up ISO 3382 (ISO 3382-2:2008 (measurement reference)). For a home studio, the RT60 target is 0.2-0.4s (voice/podcast) | 0.3-0.5s (music recording). Measurement condition: treated, unoccupied.

  2. 2

    Measure or model the room geometry

    Record the length, width, and height of the room to calculate the volume. A typical home studio has a volume of 10-60 m³.

  3. 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 (125Hz to 4kHz) from ISO 354 test data or a materials database.

  4. 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. 5

    Compare result against the standard and specify treatment if needed

    If the calculated RT60 exceeds the target of 0.2-0.4s (voice/podcast) | 0.3-0.5s (music recording), specify additional absorption. Full wall + ceiling treatment + corner bass traps is typical for a home studio to achieve compliance.

Frequently Asked Questions

What RT60 does ISO 3382 require for a home studio?

ISO 3382 (ISO 3382-2:2008 (measurement reference)) requires a reverberation time of 0.2-0.4s (voice/podcast) | 0.3-0.5s (music recording) for home studio spaces, measured in the treated, unoccupied condition per ISO 3382-2.

What background noise level is acceptable in a home studio under ISO 3382?

ISO 3382 sets a background noise limit of NR-15 (recording) | NR-25 (mixing) for home studio spaces. This typically refers to HVAC and building services noise measured with the room unoccupied.

How much acoustic treatment does a home studio need to comply with ISO 3382?

A typical home studio requires Full wall + ceiling treatment + corner bass traps of acoustic treatment to meet ISO 3382 compliance. Estimated installed cost is £1,500-£8,000 DIY | £5,000-£25,000 professional.
