    部分人的工作是长期暴露在噪音中的,像迪厅的DJ,机场的工作人员。长期处于这样的工作环境,是否会对听力造成影响?

    Rob: Hello I’m Rob and this is 6 Minute English. With me today is Finn. Hello Finn.

    Finn: Hello Rob.

    Rob: We’re talking about noise today – and looking at some of the words and phrases

    associated with noise and its opposite: peace and quiet. But, as always, let’s

    start with a question. A new survey in the UK has identified the ten jobs where

    people are most exposed to noise – noise that can cause serious damage to

    someone’s hearing. Which one of these three jobs has the most exposure to

    noise?

    a) A nightclub worker

    b) A classical musician

    c) An airport ground staff worker

    Finn: I think it’s got to be c) the person who works in the airport. Planes are very

    noisy aren’t they Rob?

    Rob: That’s true, very noisy. OK, we’ll find out if you’re right at the end of the

    programme. But now, let’s make some noise! Or at least hear some noise. This

    is a typical cacophony of sound you can hear on a busy street in London. A

    cacophony is a mix of loud sounds…. Have a listen.

    (Mix of sounds from a busy London street)

    Finn: So we heard drills, and buses and church bells in there as well, didn’t we Rob?

    It’s a real din – or bad noise – but people in urban areas all around the world

    have to live with that sort of noise all the time.

    Rob: Yes but I guess they get used to it and it's all part of city life but it does mean it

    can be difficult to hear yourself think! And I think you’ll agree the world is

    becoming noisier?

    Finn: It is. So let’s hear from Doctor Stephen Dance who went to discover how bad the

    noise in London really is. How does he describe the noise for pedestrians?

    Dr Stephen Dance. South Bank University:

    We’re here looking at the London soundscape, and as ever there is a fire engine going by, just

    as I’m talking. That is just as loud as it would be on a motorway but we’re on a side street, so

    it’s quite deafening for the pedestrians.

    Rob: That’s Stephen Dance experiencing a typical London soundscape – a soundscape

    is a mix of sounds heard in a particular location. And one of the sounds was that

    of a fire engine which was very loud!

    Finn: It was – he described it as deafening for pedestrians – so, extremely loud and

    possibly causing deafness. But how would we know a fire engine was on its way

    to an emergency without such a sound?

    Rob: It’s a good point. Sometimes a loud noise is needed so it can be heard over

    other noises. And in other situations we sometimes make more noise to drown

    out – or cover up – the sounds we don’t want to hear. So we turn our music up

    to drown out the sound of the washing machine for example!

    Finn: But of course if everyone turns up their own music the noise becomes even

    greater. So, Rob, what is the solution?

    Rob: Maybe we should all take a vow of silence! Just like a monk, we make a

    promise not to talk.

    Finn: I think that would be impossible for you Rob! Anyway, what rich people used to

    do in history was move out of the city to the relative tranquillity of the

    countryside, but then there the silence was deafening!

    Rob: And when you’re in the country, you sometimes tune in to the smallest sounds,

    like a bird singing, and that can become just as irritating. But you have to admit

    those sounds are a lot more calming than the constant noise of city life?

    Finn: Well you can sometimes hear birdsong in the city but it’s the buildings that cause

    these natural sounds to be drowned out.

    Rob: High rise buildings cause the sound to reflect off – or bounce off - each other

    causing the sound to be amplified – made louder. And buildings made of glass

    are even more reflective.

    Finn: So there’s not really a solution to reducing noise in the city – we’re just going to

    have put on our headphones and listen to our own noise – heavy metal maybe,

    that would be good, wouldn’t it Rob?

    Rob: Hmm, well, listening to the tinny sound of music coming from you headphones

    whilst on a train can be really annoying.

    Finn: Rob, maybe you should join a noise abatement group - these are groups of

    people who campaign to control levels of noise. They try to restrict planes flying

    over residential areas at night and encourage people not to disturb their

    neighbours by playing music too loudly. Maybe the big question really is what is

    noise? Some people may call a sound just noise whereas others may say it’s

    music to their ears – a beautiful sound.

    Rob: Well Finn, some people say that the best noise is no noise at all – or silence is

    golden.

    Finn: Actually Rob, when you say ‘silence is golden’ it actually means it’s often better

    to say nothing at all than say something stupid – so maybe it’s time for us to

    stop making any more noise and just get out of here?

    Rob: Not before I’ve given you the answer to today’s question. Earlier, I said a new

    survey in the UK has identified the ten jobs where people are most exposed to

    noise. I asked which of these three jobs has the most exposure to noise?

    Finn: And I said c) an airport ground staff worker. Was I right?

    Rob: You were absolutely right. The answer is an airport ground staff worker. People

    who direct jet engines in landing and take-off and are subjected to 140 decibels

    of sound in one go. It’s important to cover your ears with ear muffs in a job like

    that! OK, that’s all we have time for today but please join us again soon for more

    Both: Bye
