Thousands of people living near wind turbines could find their lives blighted by the noise, researchers have warned.

Acoustic scientists estimate up to a fifth of Britain’s wind farms generate a low- frequency hum that can be audible for more than a mile.

 

With the government planning a huge expansion of wind turbines, some experts want the limits on wind turbine noise — 35 decibels during the day and 43 decibels at night, the equivalent of a buzzing fridge — to be lowered.

The impact of the pulsating sound, a phenomenon called “amplitude modulation” (AM) which is believed to be caused by the turbine blades striking patches of turbulent air, has already led to payouts from energy companies.

Earlier this year, Jane and Julian Davis took a wind farm operator to court, claiming that the noise from nearby turbines had forced them from their Lincolnshire home. They settled for an undisclosed sum.
