Wind Turbines / Wind Farms - Noise / Health

[taffinnorfol]

I am looking at different elements of the development of industrial wind turbines in the production of electricity in the UK over the last 10 years.
Turbines are now much more powerful and on taller towers with larger blades now than 10 years ago and there is some evidence that noise may be a problem at some sites and to some local residents.
Not wishing to get into the huge debate about whether onshore wind turbines are good or bad, but has anyone got any specific information which I might be allowed to put into my research?
Thanks.

Type - noise impact wind turbines - into Google and you will get some stuff. These are the few that come up and look tasty.
