Hello and welcome to the naked scientists recorded at the Cambridge Science Center in front of this wonderful studio audience.

This time we're looking at the science of sound. We're going to be finding out what

sound is, how we make sounds, how we hear sounds, and also what we can do to reduce

sounds when it's becoming a nuisance and with us are a panel of

fantastic sound-related scientists who are sound in mind, sound in body and sound in their

knowledge of sound. Rob Toulson is the director of the Digital Economy Research Institute at Anglia Ruskin University

who works on music formats and also on the future of digital music.

He also has a background in acoustics, electronics and also music production. Are your singer wrong?

I have been known to sing on occasion, yeah. In the bath or professionally? On stage sometimes, but not so much these days.

Carrioki? I try to avoid that.

Richard Turner is an engineer who is at the University of Cambridge's engineering department.

He works on how computers recognize sounds and he's also developing noise cancelling hearing aids that can

distinguish background noise from speech and that will we hope be able to help people

to hear in very busy noisy environments. Hello Richard.

Hello, good to have you with us and you've got a massive ear on the table in front of you.

It's not being close to the back of a mouse this time, which is a step forward.

Is that just in case you're hard of hearing yourself or...

Well, it's just to point out a few of the parts of the air to the audience.

Good stuff.

And next to Richard is Nigel Peak.

He's also from Cambridge University, but he's at the Department of Applied Mathematics and

Theoretical Physics, where he studies the maths of noise.
