Hi Bernie--
Do think you we might have to rely on our animal intuitions that tell
us that noise "ain't good" and keep generating evidence (while we
can)? The main response to man-made sonic intrusions through
all-night monitoring here in a rural Wisconsin seems to be broken-off
communications. We can assume that some communications are not
initiated as well.
As you know, the slightest amount of wind in woody/grassy locations
will curtail many air-borne communications too. I think of the the
man-made intrusions as adding (many) more "wind" hours, at the very
least.
I do think its also important for each of us to become more aware of
the stresses noise creates in us in order to accelerate our learning.
Once we culturally and consciously value quiet to a great extent,
which I trust will eventually take place, the work required to
reclaim it will be easier to justify. Rob D.
