The Measurement of Low Frequency Noise at Three UK Wind Farms

URN No: 06/1412

In January 2004, an article, in the national press, alleged that Low Frequency Noise (LFN) emissions from wind turbines had given rise to health effects to neighbours of three wind farms in Cumbria, North Wales & Cornwall. As a result the then DTI commissioned an independent study to investigate the levels and effects of infrasound and Low Frequency Noise in dwellings neighbouring these three wind farms from which complaints had been received. Of the 126 wind farms operating in the UK, five have been reported low frequency noise problems. Therefore, such complaints are the exception rather than a general problem which exists for all wind farms.

Hayes McKenzie, a leading consultant on all aspects of acoustics, noise and vibration, were commissioned to carry out the study.
