It's science, but not as you know it. The Naked Scientists.

Hello, in their heads when they improvise? Also, what have sharks hunting habits and a shopper in a supermarket got in common?

Well, apparently, it's the way they walk.

Wouldn't the Bee-G's be proud of them?

And also Bat-Nav, scientists have discovered how bats use the Earth's magnetic field to find

their way home, but they didn't in this case because they got put into a magnet and got magnetized

the wrong way and they all flew from the wrong direction. That's all coming up.

See you in a second with that.

Thanks, Chris. Now this week we're also tuning into the science of sound and music.

David Howard from York University is here to explain how the voice works, where accents come from

and how an impersonator can sound so like a person

that they're taking off, you just don't know the difference, and music to your ears, or maybe

not, how the brain responds to music and why some tunes border on the intolerable.

You know the American government drove Manuel Noriega out of his compound by playing him 36 hours of ACDC music.

That was enough to drive him to surrender.

And I think we've all had that experience where you're in a shopping mall or something and they're piping in music and you wish it would just stop.

Haven't we just? I've certainly had that experience, but on a stop. and what it means to different cultures. Chris.

Thank you Helen.

So if you've got a question for us about the science of sound or music, then do get in touch.
