Wind Farm Acoustic Services

At Arthian, we deliver wind farm acoustic services to support planning, permitting, stakeholder engagement and operational compliance. Whether you’re developing a new wind farm, repowering an existing site or managing turbine complaints, we help you understand and control acoustic risks with clarity and confidence.

Our consultants support developers, operators, planners and investors across the UK and Ireland, providing robust, regulator-aligned assessments that satisfy planning authorities, local communities and technical due diligence.

ETSU-R-97 & Good Practice Guidance

We apply the UK’s official methodology for wind farm noise assessment—ETSU-R-97: The

Assessment and Rating of Noise from Wind Farms—alongside the Institute of Acoustics Good Practice Guide and supplementary guidance notes. This includes:

Background noise measurement protocols
Derivation of site-specific noise limits
Prediction of turbine noise levels
Assessment of cumulative impacts
Planning condition wording and validation

We also monitor updates to ETSU-R-97 guidance, including the 2025 consultation draft on revised noise limits and amplitude modulation controls.

Our Wind Farm Acoustic Capabilities

We offer a full suite of acoustic services across the wind farm lifecycle, from feasibility and EIA to post-construction monitoring and complaint investigation. We tailor each assessment to site-specific conditions, turbine layout, receptor sensitivity and planning context, ensuring defensible, transparent and regulator-ready outputs.

Our services include:

Baseline Noise Monitoring

Noise Impact Assessments for Planning & EIA

Compliance Monitoring & Acoustic Audits

Cumulative Impact Assessment

Community Liaison & Complaint Investigation

Expert Witness & Due Diligence

Baseline Noise Monitoring

We carry out long-term, unattended noise surveys to establish accurate baseline levels at sensitive sites, ensuring reliable data for impact assessments and compliance. This includes:

Unattended long-term monitoring: Calibrated equipment captures representative noise data across varying conditions.
Sensitive receptor focus: Monitors are strategically placed near homes, schools, and other key locations.
Environmental data integration: Wind speed is factored in to distinguish ambient noise and refine baseline characterisation.
Reliable data for planning: Robust methodologies ensure integrity and support modelling, compliance, and mitigation strategies

Noise Impact Assessments for Planning & EIA

We provide noise impact assessments for wind energy developments, supporting planning and EIAs with outcomes based on recognised standards and best practice. This includes:

Predictive noise modelling using ISO 9613 to simulate turbine sound propagation under varying conditions.
Regulatory alignment with ETSU-R-97 and the IOA Good Practice Guide to meet UK planning standards.
Impact assessment at sensitive receptors such as homes and schools, based on predicted sound levels.
Scenario testing and reporting to support mitigation strategies and stakeholder engagement with clear, planning-ready documentation.

Compliance Monitoring & Acoustic Audits

We conduct post-construction noise assessments to confirm turbine sound levels meet planning requirements and regulatory standards. This includes:

Post-construction noise monitoring at sensitive receptors to verify real-world turbine performance.
Compliance verification against planning conditions using calibrated, traceable instrumentation.
Weather-correlated data collection to reflect typical operating conditions and turbine behaviour.
Clear reporting and mitigation support through evidence-based audits and technical advice where exceedances occur.

Cumulative Impact Assessment

We assess the combined acoustic effects of multiple wind energy developments to support planning and EIA submissions. This includes:

Modelling of multiple turbine sources: Simulating noise propagation from all turbines within a proposed site.
Assessment of nearby wind farms: Including operational and consented developments to evaluate cumulative impacts.
Use of ISO 9613 algorithms: Ensuring consistent and reliable modelling of sound propagation across sites.
Planning-aligned reporting: Delivering clear outputs to support decision-making and stakeholder engagement.

Community Liaison & Complaint Investigation

We support effective communication and issue resolution throughout the lifecycle of wind energy developments. This includes:

Stakeholder engagement: Facilitating clear, proactive communication with local communities and interested parties.
Complaint resolution: Investigating noise-related concerns with sensitivity and technical rigour.
Regulator communication: Providing evidence-based responses and reports to planning authorities and environmental regulators.
Post-construction monitoring support: Linking community feedback with operational data to ensure transparency and accountability.

Expert Witness & Due Diligence

We provide specialist acoustic input to support legal, financial, and planning processes for wind energy developments. This includes:

Technical input for planning appeals: Delivering expert analysis and testimony aligned with regulatory standards.
Support for acquisitions and investment reviews: Assessing noise-related risks and compliance status during project transactions.
Due diligence for legal proceedings: Preparing robust evidence and documentation for dispute resolution and litigation.
Clear, defensible reporting: Producing concise, authoritative outputs suitable for legal and regulatory audiences.
