TED演讲:保持听力健康的八个步骤

2014-04-16    来源:网络    【      美国外教 在线口语培训

你会像爱护眼睛一样,保护好你的耳朵吗?什么样的声音会损害我们的听觉?如何才能保护好我们的耳朵? 声音专家Julian Treasure表示日益吵闹的世界正在吞噬我们的精神健康,甚至威胁我们的生命。他提出了八大法则帮助我们缓解“声音的侵袭”。

Julian Treasure: Shh! Sound health in 8 steps

Julian Treasure says our increasingly noisy world is gnawing away at our mental health — even costing lives. He lays out an 8-step plan to soften this sonic assault (starting with those cheap earbuds) and restore our relationship with sound.

Julian Treasure studies sound and advises businesses on how best to use it.

Why you should listen:

Julian Treasure is the chair of the Sound Agency, a firm that advises worldwide businesses -- offices, retailers, hotels -- on how to use sound. He asks us to pay attention to the sounds that surround us. How do they make us feel: productive, stressed, energized, acquisitive?

Treasure is the author of the book Sound Business and keeps a blog by the same name that ruminates on aural matters (and offers a nice day-by-day writeup of TEDGlobal 2009). In the early 1980s, Treasure was the drummer for the Fall-influenced band Transmitters.

0:16 The Hindus say, "Nada brahma," one translation of which is, "The world is sound." And in a way, that's true, because everything is vibrating. In fact, all of you as you sit here right now are vibrating. Every part of your body is vibrating at different frequencies. So you are, in fact, a chord -- each of you an individual chord. One definition of health may be that that chord is in complete harmony. Your ears can't hear that chord; they can actually hear amazing things. Your ears can hear 10 octaves. Incidentally, we see just one octave. Your ears are always on -- you have no ear lids. They work even when you sleep. The smallest sound you can perceive moves your eardrum just four atomic diameters. The loudest sound you can hear is a trillion times more powerful than that.

0:59 Ears are made not for hearing, but for listening. Listening is an active skill, whereas hearing is passive, listening is something that we have to work at -- it's a relationship with sound. And yet it's a skill that none of us are taught. For example, have you ever considered that there are listening positions, places you can listen from? Here are two of them. Reductive listening is listening "for." It reduces everything down to what's relevant and it discards everything that's not relevant. Men typically listen reductively. So he's saying, "I've got this problem." He's saying, "Here's your solution. Thanks very much. Next." That's the way we talk, right guys?

1:34 Expansive listening, on the other hand, is listening "with," not listening "for." It's got no destination in mind -- it's just enjoying the journey. Women typically listen expansively. If you look at these two, eye contact, facing each other, possibly both talking at the same time. (Laughter) Men, if you get nothing else out of this talk, practice expansive listening, and you can transform your relationships.

1:57 The trouble with listening is that so much of what we hear is noise, surrounding us all the time. Noise like this, according to the European Union, is reducing the health and the quality of life of 25 percent of the population of Europe. Two percent of the population of Europe -- that's 16 million people -- are having their sleep devastated by noise like that. Noise kills 200,000 people a year in Europe. It's a really big problem.

2:26 Now, when you were little, if you had noise and you didn't want to hear it, you'd stick your fingers in your ears and hum. These days, you can do a similar thing, it just looks a bit cooler. It looks a bit like this. The trouble with widespread headphone use is it brings three really big health issues. The first really big health issue is a word that Murray Schafer coined: "schizophonia." It's a dislocation between what you see and what you hear. So, we're inviting into our lives the voices of people who are not present with us. I think there's something deeply unhealthy about living all the time in schizophonia.

2:58 The second problem that comes with headphone abuse is compression. We squash music to fit it into our pocket and there is a cost attached to this. Listen to this -- this is an uncompressed piece of music. (Music) And now the same piece of music with 98 percent of the data removed. (Music) I do hope that some of you at least can hear the difference between those two. There is a cost of compression. It makes you tired and irritable to have to make up all of that data. You're having to imagine it. It's not good for you in the long run.

3:34 The third problem with headphones is this: deafness -- noise-induced hearing disorder. Ten million Americans already have this for one reason or another, but really worryingly, 16 percent -- roughly one in six -- of American teenagers suffer from noise-induced hearing disorder as a result of headphone abuse. One study at an American university found that 61 percent of college freshmen had damaged hearing as a result of headphone abuse. We may be raising an entire generation of deaf people. Now that's a really serious problem.

4:07 I'll give you three quick tips to protect your ears and pass these on to your children, please. Professional hearing protectors are great; I use some all the time. If you're going to use headphones, buy the best ones you can afford because quality means you don't have to have it so loud. If you can't hear somebody talking to you in a loud voice, it's too loud. And thirdly, if you're in bad sound, it's fine to put your fingers in your ears or just move away from it. Protect your ears in that way.

4:30 Let's move away from bad sound and look at some friends that I urge you to seek out. WWB: Wind, water, birds -- stochastic natural sounds composed of lots of individual random events, all of it very healthy, all of it sound that we evolved to over the years. Seek those sounds out; they're good for you and so it this. Silence is beautiful. The Elizabethans described language as decorated silence. I urge you to move away from silence with intention and to design soundscapes just like works of art. Have a foreground, a background, all in beautiful proportion. It's fun to get into designing with sound. If you can't do it yourself, get a professional to do it for you. Sound design is the future, and I think it's the way we're going to change the way the world sounds.

5:18 I'm going to just run quickly through eight modalities, eight ways sound can improve health. First, ultrasound: we're very familiar with it from physical therapy; it's also now being used to treat cancer. Lithotripsy -- saving thousands of people a year from the scalpel by pulverizing stones with high-intensity sound. Sound healing is a wonderful modality. It's been around for thousands of years. I do urge you to explore this. There are great things being done there, treating now autism, dementia and other conditions. And music, of course. Just listening to music is good for you, if it's music that's made with good intention, made with love, generally. Devotional music, good -- Mozart, good. There are all sorts of types of music that are very healthy.

5:57 And four modalities where you need to take some action and get involved. First of all, listen consciously. I hope that that after this talk you'll be doing that. It's a whole new dimension to your life and it's wonderful to have that dimension. Secondly, get in touch with making some sound -- create sound. The voice is the instrument we all play, and yet how many of us are trained in using our voice? Get trained; learn to sing, learn to play an instrument. Musicians have bigger brains -- it's true. You can do this in groups as well. It's a fantastic antidote to schizophonia; to make music and sound in a group of people, whichever style you enjoy particularly. And let's take a stewarding role for the sound around us. Protect your ears? Yes, absolutely. Design soundscapes to be beautiful around you at home and at work. And let's start to speak up when people are assailing us with the noise that I played you early on.

6:46 So I'm going to leave you with seven things you can do right now to improve your health with sound. My vision is of a world that sounds beautiful and if we all start doing these things, we will take a very big step in that direction. So I urge you to take that path.

7:01 I'm leaving you with a little more birdsong, which is very good for you. I wish you sound health.

7:05 (Applause)
