Concert Hall Acoustic Design to NCC 2022 / AS/NZS 2107:2016

Concert halls represent the pinnacle of acoustic design, requiring simultaneous optimisation of seven ISO 3382-1 parameters. The target RT60 of 1.

TL;DR

Under NCC 2022 / AS/NZS 2107:2016, a concert hall of 6,000-10,000 m³ (typical dimensions 35m × 22m × 14m) requires an RT60 of 1.8–2.2s at 500-1000 Hz. Background noise must not exceed 20 NR. Australian concert hall design follows ISO 3382-1 with NCC 2022 referencing AS/NZS 2107 for background noise criteria.

Step-by-Step Compliance Calculation

1
Reference AS/NZS 2107 for noise
Set background noise target of NR 15-20 per AS/NZS 2107 for auditoria and concert halls.
2
Apply ISO 3382-1 for acoustics
Design hall acoustic parameters following ISO 3382-1 targets for the intended performance programme.
3
Design HVAC for climate
Size HVAC systems for Australian cooling loads while maintaining NR 15-20 at all audience positions.
4
Commission per ISO 3382-1
Measure all seven ISO 3382-1 parameters and background noise per AS/NZS 2107 methodology.

Common Failure Modes

⚠️External traffic noise

Australian concert halls in urban locations require exceptional facade insulation to meet NR 15-20 targets.

⚠️Air conditioning noise in tropical climates

High cooling loads in Australian climates require oversized, low-velocity HVAC to meet stringent noise criteria.

Frequently Asked Questions

What RT60 does NCC 2022 / AS/NZS 2107:2016 require for a concert hall?

NCC 2022 / AS/NZS 2107:2016 requires a reverberation time of 1.8–2.2s at 500-1000 Hz for concert hall spaces. Australian concert hall design follows ISO 3382-1 with NCC 2022 referencing AS/NZS 2107 for background noise criteria. Concert halls require NR 15-20. The Association of Australian Acoustical Consultants provides supplementary guidance for performance venue design in the Australian context.

What is the maximum background noise level for a concert hall under NCC 2022 / AS/NZS 2107:2016?

NCC 2022 / AS/NZS 2107:2016 sets a maximum background noise level of 20 NR for concert hall spaces. This includes noise from HVAC systems, building services, and external intrusion, measured with the room unoccupied. Exceeding this limit degrades speech intelligibility and occupant comfort.

How much acoustic treatment does a concert hall need to comply with NCC 2022 / AS/NZS 2107:2016?

A typical concert hall (6,000-10,000 m³) requires Shaped reflectors (NRC ≥0.08) covering 70% of the ceiling as the primary treatment. Additional wall absorption on 2 surface(s) is typically needed. Use the AcousPlan calculator with the pre-loaded dimensions (38m × 21m × 14m) to calculate the exact absorption deficit for your room.
