QLD EPP Noise Explained | Acoustic Quality Objectives

The Queensland Environmental Protection (Noise) Policy 2019 (EPP Noise) is the primary framework used to assess environmental noise across Brisbane, Gold Coast and wider Queensland.

Published by the Queensland Government, the policy defines how noise is assessed to protect community health and amenity during development and operation.

Unlike NSW, the QLD framework is based on Acoustic Quality Objectives (AQOs) rather than background noise +5 dB criteria.

When You Need This

The EPP Noise applies to:

• Development applications involving mechanical plant or commercial activity
• Industrial and warehouse developments
• Cafes, gyms, and entertainment venues
• Mixed-use developments near residential areas
• Projects requiring acoustic reports for council approval

The policy is used to determine whether a project meets acceptable environmental noise levels at sensitive receivers.

Applicable Standards / Requirements

Governing Authority

• Queensland Government

Core Document

• Environmental Protection (Noise) Policy 2019 (EPP Noise)

Key Compliance Requirement

To comply with the EPP Noise:

• Noise levels must meet Acoustic Quality Objectives (AQOs)
• Criteria are based on:
  • Land use
  • Time of day

Assessment Methodology

The EPP Noise establishes a structured approach based on environmental values and measurable noise limits.

1. Acoustic Quality Objectives (AQOs)

AQOs define maximum acceptable noise levels for different environments.

They are based on:

• Residential areas (more stringent limits)
• Commercial or industrial areas (higher allowable levels)
• Time periods (day, evening, night)

AQOs are typically expressed as LAeq,adj.

2. Environmental Values

The policy is built around protecting:

• Health and wellbeing
• Community amenity

Noise assessments must demonstrate that these values are maintained.

3. Noise Measurement Metric

QLD assessments are generally based on:

• LAeq,adj (equivalent continuous noise level, adjusted)

This differs from NSW, where LA90 and background levels are central.

4. Planning Scheme Integration

AQOs are applied through:

• Local government planning schemes
• Development conditions
• Council-specific requirements

Councils use AQOs to determine whether a development is acceptable.

5. Project Noise Assessment

Acoustic reports must:

• Predict operational noise levels
• Compare results to applicable AQOs
• Demonstrate compliance or identify exceedances

Compliance / Outcomes

To achieve compliance under the EPP Noise:

• Predicted noise levels must not exceed AQOs
• Assessments must consider:
  • Land use context
  • Time-of-day limits

Acoustic reports must clearly demonstrate:

• Methodology
• Assumptions
• Compliance outcomes

This is required for development approval in Queensland.

Mitigation / Design

Where exceedances occur, mitigation may include:

• Acoustic barriers or enclosures
• Equipment selection and control
• Site layout optimisation
• Operational restrictions

Mitigation is designed to achieve compliance with AQOs while maintaining functionality.

Our Reports

AACG prepares acoustic reports aligned with the EPP Noise, including:

• Identification of applicable AQOs
• Noise modelling and LAeq predictions
• Assessment against environmental values
• Compliance tables and interpretation
• Practical mitigation recommendations

Reports are structured for planning approval and regulatory review.

Our Process

1. Review of project and applicable AQOs
2. Site and operational assessment
3. Noise modelling and prediction
4. Compliance assessment
5. Mitigation design (if required)
6. Final report for submission
