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?

"Acoustic ecologist" is basically a fancy name for someone who tries to become a better listener. Not just listening to those thoughts, ideas, and productions of human intention, but listening to places - whether it's an urban environment, residential, industrial, or even the farthest corner of the world, in one of our last great quiet places where we can listen to the pure sounds of nature without any human-caused noise intrusions.

The most sensitive frequencies are at the resonant frequencies of the auditory canal. In other words, the ear has shaped itself to naturally amplify certain bandwidth. And that corresponds to sounds in that bandwidth that were most important to our evolving ancestors to hear, in order to survive. And it doesn't match the human voice. It matches birdsong.

I would say that to listen is to become aware. To become truly informed. You will discover whatever you do.

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.

What visual information does is it creates priorities. You cannot know with certainty what lies behind something else. There are very few transparent materials in the natural world or the built environment. And so we deal with things superficially, and we deal with what's in front of us, not what's behind our head that we can't see, or to the left or the right. Visualists are often linear and timeline-oriented, whereas the natural condition and the natural way of problem-solving throughout evolution is to be multitasking.

If you're going to listen, you have to be willing to be changed by what you've heard. My life has gone through so many changes. I'm sixty-two years old right now, and I'm as busy changing now as I was when I was a teenager, or in my twenties. Every day is different. Every day brings new information.
