Hayes McKenzie have been industry leaders for over 20 years in the field of noise from wind turbine developments; from small scale single micro turbines to multi-megawatt sites of over 300 turbines. As well as providing advice and measurement services to developers, local planning authorities and local residents on over 700 sites in the UK and overseas, the practice has been responsible for, or contributed to, a number of government research projects.

Government research projects

• Mynydd Y Cemmaes Wind Farm Impact Study
• Objective and Subjective Rating of Tonal Noise Radiated from UK Wind Farms
• Propagation of Noise from Wind Turbines over Variable Terrain
• A Critical Appraisal of Wind Farm Noise Propagation
• The Measurement of Low Frequency Noise at Three UK Wind Farms
• Research into Aerodynamic Modulation of Wind Turbine Noise
• Analysis of How Noise Impacts are Considered in the Determination of Wind Farm Planning Applications

Further work for public bodies has included

• Provision of evidence to the Welsh Affairs Select Committee with respect to noise from wind farm developments
• Drafting of a significant proportion of the technical detail in ETSU-R-97
• Providing technical advice and drafting for Fehily Timoney EPA Guidance Note NG3 - Noise Assessment of Wind Turbine Operations at EPA Licensed Sites (NG3)
