Introduction
AACG provides aircraft noise intrusion reports for development applications (DA), council submissions, and building design compliance across Australia, including Sydney and NSW.
Our reports are prepared in accordance with:
- AS 2021 – Aircraft Noise Intrusion
- Australian Noise Exposure Forecast (ANEF) system
- Applicable planning and council requirements
We deliver clear, buildable acoustic requirements aligned with approval and construction outcomes.
When You Need an Aircraft Noise Report
An aircraft noise assessment is required where:
- The site is within or near ANEF 20 or higher
- A development application (DA) is being submitted
- Council requires an acoustic report for aircraft noise
- Residential or sensitive-use buildings are proposed
- Design compliance with AS 2021 must be demonstrated
Early engagement allows requirements to be integrated into design before documentation is finalised.
Aircraft Noise Compliance Requirements (ANEF & AS 2021)
Aircraft noise is regulated through the ANEF system, which defines exposure levels based on:
- Aircraft movement frequency
- Flight paths and runway usage
- Predicted external noise levels
Within ANEF 20 and above:
- Formal acoustic assessment is required
- Buildings must achieve defined internal noise levels
- Compliance must be demonstrated through a documented acoustic report
Typical internal targets include:
- 50 dB(A) — sleeping areas
- 55 dB(A) — living areas
- 60 dB(A) — non-habitable spaces
These criteria must be achieved through controlled building design.
Construction Requirements for Aircraft Noise Control
Standard residential construction is not sufficient within aircraft noise affected areas.
Compliance requires coordinated upgrades across the building envelope.
Glazing Systems
- Laminated or double glazing
- Increased glass thickness
- Full perimeter acoustic sealing
External Walls
- Multi-layered construction systems
- Insulated cavities
- Airtight internal linings
Roof and Ceiling Systems
- Increased mass and insulation
- Controlled detailing at junctions
- Treatment of primary transmission pathways
Penetrations and Sealing
- All service penetrations sealed
- Airtightness maintained across envelope
System performance depends on complete envelope integrity, not isolated upgrades.
Ventilation Requirements in Aircraft Noise Areas
Ventilation is a controlled constraint in aircraft noise environments.
Within ANEF 20 and above:
- Open windows cannot achieve compliant internal noise levels
- Buildings must be assessed under closed-window conditions
As a result:
- Mechanical ventilation or air conditioning is required
- Systems must be integrated without compromising acoustic performance
Poor integration can introduce new noise paths and reduce effectiveness.
How Aircraft Noise Is Assessed
AACG applies a structured assessment methodology aligned with AS 2021.
Site Analysis
- Identification of ANEF contour classification
- Review of flight paths and aircraft activity
Noise Modelling
- Assessment of representative aircraft events
- External noise typically in the range of 75–85 dB(A)
Internal Noise Prediction
- Evaluation of transmission through glazing, walls, and roof systems
- Consideration of material performance and configuration
Output
- Predicted internal noise levels
- Defined construction requirements for compliance
Our Reports
AACG aircraft noise reports:
- Prepared for development applications (DA) and council submission
- Fully aligned with AS 2021 and ANEF requirements
- Structured for certifier and planning authority review
Each report includes:
- Site-specific aircraft noise assessment
- Internal noise level targets
- Detailed building envelope requirements
- Ventilation strategy requirements
- Clear, buildable construction specifications
Our Process
AACG applies a controlled, repeatable process:
- Review of planning requirements and ANEF mapping
- Integration with architectural drawings
- Translation of acoustic targets into construction systems
- Coordination during design and documentation
Outputs are:
- Buildable
- Clearly documented
- Suitable for approval without rework
Our Quality
AACG reports are defined by:
- Technical accuracy
- Verified data inputs
- Worst-case scenario modelling
- Consistent documentation standards
We do not issue generic or templated reports.
Each assessment is site-specific and compliance-driven.
Our Commercial Approach
Aircraft noise requirements directly impact:
- Glazing systems
- Wall and roof construction
- Mechanical services
AACG ensures:
- Requirements are defined early
- Over-specification is avoided
- Solutions align with construction methods and project budgets
This reduces redesign risk and improves delivery certainty.
