When we listen, it's not linear, it's 360, and it's in a time-space continuum, so you don't have to create a list of priorities, because it's all important. You can deal with everything at any given time. Not only that, but it happens very simply, without effort.

I'm in love with Earth. I truly am. And so listening is not work, to work toward a better future. It's joy. To not be able to work toward a better future would be work. That would be tough.

Most people think visual information is more important than aural information - like, what's this big deal about sound? And why should I bother to listen, rather than look? And here are the facts: there are blind species, in the backs of the caves, the bottoms of the oceans. It's not essential on planet Earth to be able to see, to be a species. But there are no deaf animal species. You have to be able to hear, or you won't get the information you need in order to survive.

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.

We're all born listeners. And as a result of our modern lives, and living in a world that has less meaning than the natural world that we evolved to hear, we learn to think of listening not as taking in all the information with equal value, which is the definition of true listening. In our modern world, we tend to think of listening as focusing our attention on what is important and filtering out everything else.

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.

"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.
