Hi everyone,
So, here is an interesting dilemma, I thought I would
pose and see who else has encountered it, and what
could be done about it.
We have some very large windmills just to my north,
some of the largest in the world, actually. With a 90
/meter/ span. (I am on the south bank of the
Sacramento River, they are on the north, about a mile
away).
And, under unusual conditions, with winds aloft but
calm at the surface, you can actually hear them
rotating. Kind of a low-frequency 'whoosh....
whoosh.... whoosh....'.
So, I thought. Very cool, I *have* to get a recording
of this.
What is the result? Pretty much every sound in the
environment -except- these blades.
I know I can hear them-- so why can't the microphone,
which can hear everything else?
Has anyone else encountered such a thing? What kinds
of things can you do to pick these things up? They are
sounds, but they are getting pretty close to 'pressure
waves', or subtle changes in background. Thing is, I
can hear them clear as day... so what to do?
Any thoughts or comments would be appreciated.
Thanks,
Mark
