An environmental noise assessment evaluates the impact of noise emissions on surrounding environments and ensures compliance with regulatory requirements.
Unlike standard development-focused assessments, an environmental noise assessment in Australia addresses broader obligations under EPA policies, industrial operations, and ongoing compliance conditions.
AACG delivers environmental noise assessments aligned with state-based environmental legislation, supporting both planning approval and operational compliance.
When You Need This
An environmental noise assessment is required for:
- Industrial and commercial developments
- Warehouses and manufacturing facilities
- Service stations and infrastructure projects
- Mechanical plant operating under EPA regulation
- Developments with ongoing environmental compliance obligations
- Projects requiring EPA licensing or regulatory review
These assessments are typically required where noise emissions must be controlled to protect surrounding environments over the long term.
Applicable Standards / Requirements
Environmental noise assessments are governed by state environmental policies and national standards.
New South Wales (NSW)
- NSW Noise Policy for Industry (NPfI)
- NSW Environment Protection Authority
Key criteria:
- Intrusive noise limits (LAeq vs LA90 background levels)
- Amenity-based noise criteria
- Time-of-day restrictions
Queensland (QLD)
- Environmental Protection Act 1994
- Environmental Protection (Noise) Policy 2019
- Queensland Department of Environment and Science
Key criteria:
- Acoustic quality objectives
- Environmental harm thresholds
South Australia (SA)
- Environment Protection (Noise) Policy 2007
- Environment Protection Authority South Australia
Key criteria:
- Assigned noise levels
- Zone-based compliance limits
National Standards
- AS 1055 — Environmental noise measurement
- AS/NZS ISO 1996 — Environmental noise assessment
These define how an environmental noise assessment report must be prepared and evaluated.
Assessment Methodology
AACG applies a structured methodology to all environmental noise assessments:
1. Site and Operational Review
- Identification of noise sources
- Operational characteristics and hours
- Receiver classification
2. Background Noise Monitoring
- Measurement of LA90 background levels
- Establishment of baseline conditions
3. Acoustic Modelling
- Prediction of operational noise emissions
- Consideration of propagation, shielding, and terrain
4. Compliance Assessment
- Comparison against EPA criteria
- Intrusive and amenity analysis
5. Mitigation Strategy
- Engineering solutions to achieve compliance
Compliance / Outcomes
A compliant environmental noise assessment will:
- Demonstrate alignment with EPA policies
- Confirm whether operational noise meets regulatory criteria
- Identify non-compliances and required mitigation
- Support planning approval or licensing requirements
These assessments are critical for both approval and ongoing operational compliance.
Mitigation / Design
AACG provides practical mitigation strategies where required:
- Acoustic enclosures and barriers
- Equipment selection and modification
- Site layout optimisation
- Operational noise controls
All solutions are designed to achieve compliance efficiently while maintaining operational practicality.
