Only 15 of 521 sites have a noise problem caused by turbine blades stalling when wind speed drops - and software can fix it.
Only about 3% of windfarms in the UK are likely to produce a low-frequency sound that can heard up to a kilometre away.
The thumping "Whoomph"-like sound, produced when the blades on a turbine partially stall because of changes in wind speed and direction, is about as loud as the noise from a single carriageway road, according to a review of evidence on the effect.
Opponents of windfarms often cite noise concerns along with aesthetic complaints, but the problem is shown to be infrequent and can be easily fixed with software changes, said trade body RenewableUK, which commissioned the report. The noise - known as other amplitude modulation - is different to the normal "whooshing" sound that can be heard close to turbines as they cut through the air, known as amplitude modulation.
Polls have repeatedly found the majority of the British public are in favour of wind power, but onshore windfarms have become increasingly political contentious, with Tory MPs calling for cuts to subsidies. Onshore wind subsidies were cut 10% in April and further cuts were announced earlier this month.
