There will be some 50,000-80,000 cyclists here in Milwaukee for 
harley fest labor day weekend. They will parade at .5mph-- each one 
rev-ing up and down fin full display. I know from analyzing the 
recordings that Harleys, alone, make up a very large part of the 
ubiquitous urban "rumble" that evelopes us-- even without the 
visiting riders.  At this moment, a fireworks display downtown pounds 
through the walls of my studio. What is this infatuation for loud 
sounds about?

In contrast, I just got back from a week in the North Dakota 
Badlands.  No off-road motorized vehicles policy. One absolutely 
windless night I was able to hear and record things I've never 
encountered before-- like the hiss of tree leaves popping and 
clicking and contracting in the cool evening air and coyotes 
conversing over a distance of at least 2 miles. After a few days in 
such a setting, I can sense the whine of nervous system drop in pitch 
and volume. Its got to be healthier. Rob D.
