The bi-annual Wind Turbine Noise Conference was held in Denver, in August 2013. The conference is hosted by ICEN: Europe (International Institute of Noise Control Engineering) and looked at 79 research papers about wind turbine noise around the themes of:

• Low frequency noise and infrasound: Measurements and effects
• Amplitude modulation
• Instrumentation
• Effects of WTN on individuals
• Sound Imission and Emission Measurements
• Structure-borne Noise/Vibration
• Propagation Wind Effects Modelling
• Regulations & Policies.

A few of these papers are now in the public domain – one of them is the work of Paul Schomer – one of America’s leading acoustic experts – and a band of others, including medical researchers – aimed at reaching an understanding as to why a significant proportion of wind farm neighbours suffer motion-sickness like symptoms. The opening summary of the paper says:

For at least four decades there have been reports in scientific literature of people being made…
