Noise assessment and shadow flicker mitigation for wind turbines
Wind energy developments must be assessed for noise impacts using ETSU-R-97 methodology and relevant guidance. Potential impacts from amplitude modulation and shadow flicker on affected properties must be carefully considered and minimized through mitigation.
ETSU-R-97 remains the UK standard methodology for the assessment of noise from wind energy development and it, along with 'A Good Practice Guide to the Application of ETSU-R-97 for the Assessment and Rating of Wind Turbine Noise' prepared by the Institute of Acoustics, should be taken into account by decision-takers. Potential noise impacts, including amplitude modulation from wind turbines on affected properties must be carefully considered. Any potential impacts from wind energy proposals which are likely to result in shadow flicker on affected properties should be minimised and mitigated.
