AACG provides air conditioner noise assessments for residential properties in Brisbane.
Assessments are prepared in accordance with:
- Brisbane City Council noise requirements
- Environmental Protection Act (QLD)
- Applicable local environmental health regulations
We deliver measurable, compliant, and defensible acoustic outcomes for development approval and noise compliance.
When You Need an Air Conditioner Noise Assessment
A noise assessment is required where:
- Installing or relocating an air conditioning unit (AC)
- Submitting a development application (DA)
- Council requires an acoustic report
- A noise complaint has been raised by neighbours
- Verifying compliance with Brisbane City Council noise limits
This applies to:
- Houses and townhouses
- Duplex developments
- Residential additions and upgrades
Brisbane City Council Noise Criteria
Air conditioner noise in Brisbane is regulated by strict background-based limits.
Noise must be assessed at the nearest affected property.
Daily Noise Limits
- 7am – 10pm:
- ≤ background noise level + 5 dB(A)
- 10pm – 7am:
- ≤ background noise level + 3 dB(A)
These limits are:
- Applied at neighbouring properties
- Based on measured background noise (LA90)
- Enforced by council for nuisance noise
What This Means in Practice
These limits are low and highly restrictive.
Typical background levels:
- Quiet residential area: ~35–45 dB(A)
This means:
- Even small increases can result in non-compliance
- Many standard AC units can exceed limits without treatment
Compliance depends on:
- Equipment selection
- Location and orientation
- Distance to neighbours
- Shielding and barriers
Noise Assessment Methodology
AACG applies a structured assessment process:
- Measurement of background noise levels (LA90)
- Identification of affected receiver locations
- Measurement or prediction of AC noise levels
- Comparison against BCC criteria
Where required, we undertake:
- On-site noise monitoring
- Acoustic modelling of equipment
- Worst-case operational assessment
