If just reading the words ‘wind turbines’ makes you feel physically sick then spare a thought for the people who have had them thrust into their lives. A new report shows living near a wind turbine may harm emotional wellbeing after scientists discovered that low frequency sounds generated by rotor blades trigger a part of the brain which senses danger.
According to the Daily Telegraph, brain scans show that even infrasound as low as 8hz – a whole octave below the traditional cut off point for human hearing – is still being picked up by the primary auditory cortex. This is the part of the brain which translates sounds into meaning.
And a separate part of the brain, linked to emotions, also lit up when the seemingly ‘inaudible’ noises were played to volunteers in a lab.

As the wind turbine industry is coming of age it is becoming clearer and clearer that they are of no benefit.
Look at what European countries and Australia are doing. They are reducing subsidies for wind energy as it is too costly and unreliable.
One country made enough electricity to give its people free power and supply its nieghboring country with its excess .
And what country might that be 3:56?
The pitch and gearing of the blades can be modified to change the frequency and decibel level of the sound produced. I'd love to have an energy producing wind turbine on my farm.
The devastating health impact of wind turbines can no longer be covered up. Science proves, excessive noise is harmful to humans. Placing turbines in excess of 400 feet within 1/2 mile of residences is wrong and it is time to remedy it. All wind turbines within 2600 feet of people should be decommissioned at the wind facility expense.
Excessive noise is a real stressor, regardless of source, especially on the extreme ends of the audio spectrum. But there are many other noisy things in life as well.
Not quite. The wind turbines that I've seen in Europe aren't placed in populated areas, though.
