Quite a good article in the Nov/Dec AARP magazine titled "Listening
for Quiet".
It talks about a silent sanctuary in Washington's Olympic National
park. The article concluded by someone complaining about the silence broken
by a small plane.

The article said "The small plane flying north more than doubles the
ambient sound,
and we react to the intruder as a threat, drawing in, tracking the
source, hunching for
cover until the last traces of engine noise finally die away."

I believe there are better sanctuaries for silence in the world than a park.
In the 60's, they made a bunch of bomb shelters, and I think they would be a
much better place to find absolute silence if one is searching for that.
