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.

I've never really understood how people cannot value the future, or think that the world is going down a fast slippery slope of degradation. No, I don't think so; this is just what it's going to take to wake us up, and allow us to do what our ancestors did. You know, our ancestors brought us here by tooth and claw. A lot of people perished, a lot of pre-humans perished. Life has never been easy. Why should it be easy for us?

The Hoh Valley is an incredibly secure area. Any event occurs around us, we will instantly become informed of that event. This can even happen at a distance. When the body recognizes that you have a very large listening area, and you're getting all the information, the body relaxes. You can breathe more gently, the cortisol levels that are created by stress in our bloodstream dissipate, and we actually become healthier. And as a result, if we are actually fortunate enough to live in a place like that, we will live longer.

The most important thing for our species is, before it speaks, to listen to its environment. That has a higher priority in any species' survival. We need to be listening to our environment - in other words, restoring the quiet - not just to our natural areas, but also to towns like Portland, Maine.

I'm very thankful, hearing impairment or not, that I've brought listening into my life. I will never say that I'm a good listener, however. Thinking that I was a good listener was one thing that kept me from being a good listener. It's a very dangerous thought. I just want to be better.

Healthy areas that are richest in information are those areas in the wild where we can get all the information that's available to us within our human hearing range. The most valuable information throughout human evolution has been faint sounds. We tend to think in our modern world that if it's loud, if it grabs our attention, it's important. We get a lot of that in advertising. But in nature, it's the faintest sound that's important; it has determined, in the past of our ancestors, perhaps, if they will live or die. Faint sounds are the earliest clues of newly arriving information.

An acoustic ecologist is a listener who is aware that sound is information. It's information because it's created by events, events produce sound, and that sound has all kinds of data, if you will, that conveys what event occurred, what the materials were, whether it was sudden, slow, loud, in what direction. And because it is information, we can think of it as a message. The acoustic ecologist studies information systems that are both intentional and sometimes wild.
