http://www.bwea.com/ref/lowfrequencynoise.html is a good
introduction to the rebuttals.
"...from current designs of wind turbines..."
Glad you have read it. Do you have a point to make about it?

Perhaps those affected were from earlier generations of blade design.

Once you get below about 16Hz there are some quite pronounced
psychoacoustic effects. In fact some of the huge pipe organs can
generate sounds down in the infrasonic region. When used, these add a
sense of drama to a performance and in many cases cause the listener to
feel "unsettled".

I just love some of the stuff you can learn on newsgroups :-)

I remember reading an article in the Beezer or TV21 (can't remember)
when I was a kid, about how sound waves at 5Hz could kill you

.... right next to the X-Ray Specs and the seebackroscope IIRC

There were concerns after the TV Centre in Shepherd's Bush was built
that wind blowing across the top of its doughnut shape would cause
issues like this.

I would think that there would be more interest in seeing through men's
clothes there.....

There was an article in New Scientist a couple of weeks ago about a
building near the Coronation Street sets which is causing trouble for
the sound engineers 'cos of the howling it makes.

Wimps. Family Affairs had the main Sunlight laundry for South London next
