Onshore Wind Noise Assessment

Accu Acoustics has extensive onshore wind noise assessment experience at sites all across the UK, covering all aspects of wind farm noise.

 

All Accu Acoustics’ consultants are grade-appropriately qualified as corporate or associate members of the Institute of Acoustics (IoA) and have either completed or are currently in the process of completing the IoA postgraduate Diploma in Acoustics and Noise Control.

​

Core Services

  • Input to feasibility studies and provision of preliminary advice;

  • Input to EIA Screening / Scoping;

  • Baseline surveys;

  • Construction and road traffic noise assessments;

  • Operational noise assessments in accordance with ETSU-R-97 and the IoA Good Practice Guide (IoA GPG), typically as chapters within an EIA Report;

  • Mitigation modelling and directivity analysis to consider the ability of a development to meet cumulative noise limits, seeking to avoid the requirement for mitigation;

  • Inputs to Construction Environmental Management Plans (CEMPs);

  • Evaluation of noise from associated plant, such as substations and Battery Energy Storage Systems (BESS);

  • Post-submission support, including review and input to draft planning conditions; and

  • Compliance monitoring.

​

We select our monitoring equipment based on its tested reliability in the field. Wherever possible we seek to build resilience into our surveys to minimise the likelihood of costly extensions or delays.

 

We have established excellent relationships with providers of wind monitoring systems and can provide recommendations for obtaining reliable and flexible SoDAR or LiDAR surveys.

 

Accu Acoustics makes use of a variety of digital tools, seeking to make the process of wind farm noise assessment more efficient and reliable. We use CadnaA noise prediction software, which operates according to the ISO 9613:2024 standard. In addition, we have developed in-house tools within programming language MATLAB to enable us to quickly and reliably process baseline data for the derivation of noise limits and undertake directivity analysis.

​

We have a GIS-based tool which can rapidly determine the applicability of correction factors recommended in the IoA GPG, with regard to concavity and topographic screening of turbines at receptor locations.

Our team of acoustic experts have good working relationships with the Environmental Health departments of numerous local authorities. We are familiar with the supplementary guidance for wind turbine noise assessment which some local authorities have produced. In addition, we have successfully worked with co-professionals working on behalf of developers of cumulative schemes, seeking to agree an equitable split in noise limits between prospective developments.

 

Accu Acoustics prides itself on embedding seamlessly into your project team from an early stage. We seek to provide initial advice on project constraints at as early a stage as possible. We bring a fresh approach to environmental noise, provide clear and accessible communication throughout our projects and produce a high standard of written deliverables.

 

Our reports and other deliverables are supplemented by clear and concise graphics and figures. We seek to enable readers of a wide range of backgrounds and levels of technical expertise to understand the assessment process, while retaining an appropriate level of technical detail.
