In the planning phase, noise contributions are calculated based on the wind turbine manufacturer’s sound power level and the project layout. For documentation calculations to demonstrate the total noise contribution from a wind farm, at least three turbines are measured if all turbines are identical.
Acoustics, noise and vibration
Wind turbine noise measurement and consultancy
Obtain measurements and documentation for wind turbine noise for planning, type approval and authority documentation.
Energy companies and project planners need documentation for wind turbine noise when projects are planned, changed or prepared for authority review. Without reliable calculations and noise measurements, it becomes difficult to assess the impact on nearby areas and move planning forward.
Impartial consultancy for wind projects
We provide impartial consultancy, measurement and calculation of wind turbine noise for planning, environmental assessment and documentation. The service includes calculations of noise contributions at neighbouring areas and delivers documented results that can be used in authority processes. The work builds on long-standing collaboration with companies, authorities and research institutions in the energy sector.
Challenges
When wind turbine noise is not documented with recognised calculations and measurements, planning and authority processes lose a reliable basis for decisions.
Missing noise documentation can delay project processing
Without documented wind turbine noise calculations and measurements, authorities cannot assess whether a project meets applicable noise limits. This delays application processing and weakens the basis for project decisions.
Documented noise basis for environmental assessment
If the noise basis for wind turbines is not sufficiently documented, uncertainty arises regarding the impact on the surroundings. This uncertainty can weaken the basis for the company’s environmental assessment.
Noise propagation is different over water
Noise from offshore wind turbines must be assessed using calculations that account for sound propagation over water. If that context is not documented, the impact on coastal areas cannot be adequately evaluated.
Benefits
Receive documented wind turbine noise results that support planning, authority dialogue and project decisions.
Use results that fit recognised practice
When measurements and calculations are prepared with recognised methods, the results can be used more consistently in technical documentation and authority processes. This gives project teams a clearer basis for presenting how the noise assessment has been carried out and what the reported results cover.
