Not only does the modern person often think that sight is more important than sound - there's no objective evidence to indicate that. Many people, even audiologists who study the science of human speech and hearing, have assumed for a long time that the human ear evolved to hear the human voice, rather than the voice changing to fit the human ear. And the human ear is actually not a perfect match if we map its sensitivity to the different frequencies in the human range of hearing; it's an unequal curve, it's kind of a wavy line.
Gordon HemptonWhenever you're in a natural system and you're making sound, you are putting yourself at risk. As you go up the evolutionary ladder, from insects to frogs to birds and on up into mammals, the higher intelligence recognizes that when you vocalize, you put yourself at risk. So mammals generally vocalize or make noise much more rarely than, let's say, insects or frogs. And when they do, and put themselves at risk, it has to be worth the risk, and have true meaning, such as signaling during a hunting party, calling in prey, some religious or spiritual ceremony, something like that.
Gordon HemptonHow are we going to know what sounds are important before we've even heard those sounds? It's an absurd question. The only thing we can say is that we're going to base it on our past experience. In other words, modern listening doesn't inform us of anything new. It simply keeps us in the past.
Gordon HemptonThe 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.
Gordon HemptonI'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?
Gordon HemptonWhen you listen to nature, it may still be difficult to live a life, but it's inspiring.
Gordon HemptonIf you're tired of getting additional information, you can just close your eyes, get some sleep. But earlids, covering of the ears, never evolved. Not once do we find it, even in the fossil records. Because while we let our eyes relax, our ears are still hearing. And that's why alarm clocks work and wake us up. We still gather information. Every animal is gathering information 24/7. So I like to think of acoustic ecologists as people who are trying to become better listeners, 24/7.
