Wind turbine noise warnings were dismissed by civil servants

A warning about the health effects of noise from wind turbines was removed from a government study following pressure from civil servants.

Consultants recommended lowering night-time noise limits because the sounds made by spinning blades were enough to disrupt sleep patterns. 

However, the advice, contained in a draft version of their 2006 report, was removed from the final submission which was eventually used in official guidance for local authorities ruling on planning applications from wind farm developers.

It means that hundreds of turbines at wind farms in Britain built since 2006 have been allowed to continue generating high levels of noise. 

Evidence of the changed advice was uncovered after a two-year battle using the Freedom of Information Act by campaigners opposed to a wind turbine development close to their home at in mid-Devon.

One of those campaigners, Mike Hulme, said: “This proves what we have been saying all along, that the noise guidelines should be reviewed. They haven’t changed substantially since 1997, in which time the design of turbines has changed and the number of wind farms has increased.

“Turbines used to be about 50 feet and now they are closer to 400 feet.

"Residents are afraid to complain to their council because the problem is then in the public domain and it becomes impossible to sell their house."

The noise warnings were made in a draft report by Hayes McKenzie Partnership (HMP).
