Noise pollution is basically defined as the presence of simple information that makes it impossible to hear all the other more delicate - and often more important - information. Noise pollution creates, if you will, dumb environments. Our industrial areas, many of our downtown urban areas, are dumb acoustic environments. Very simple, very loud, often unhealthy.

Often how you define the problem will determine whether or not you're able to find a real solution.

I believe that our distant nomadic ancestors came forward and survived because they could hear distant, faint birdsong as an acoustic navigational beacon, if you will, and by moving toward the birdsong, they were able to find places with shelter, food, and water, and a prosperous growing region. Indeed, birdsong is the number one indicator of habitats prosperous to humans.

When you listen to nature, it may still be difficult to live a life, but it's inspiring.

The earth has continued to change, from rapid climatic changes that have caused the glaciers and the ice sheets to basically bulldoze the landscape and cause species compression in the tropics and cause mass species extinction - you know, all these huge changes. In terms of evolution, every species is doomed to eventual extinction. The natural world is constantly changing. So, to deal with "environmental problems," in quotes, totally misses the issue. That is not the way we want to define our problem if we're going to find our solution.

If you're listening to a symphony, you're getting all the information, including the audience around you, the delay from the sides of the concert hall, the whole thing. If one of those musicians is sharply out of tune or starts to play a different piece of music than all the others in the orchestra, you immediately notice. When you analyze systems by listening, you can just listen, and you can tell whether the system is healthy or unhealthy. What I've created for you is a perfect model of how we should be listening to our stock market, rather than trying to see it graphically.

We think the problem is out there, when the problem is really in here - who we are and how we experience the world around us. The acoustic ecologist listens, as the primary sense, to the world around us, and I believe that they have a significant contribution to make to all environmental groups who think that they're solving environmental problems, when we're actually all on a spiritual pilgrimage.
