BBC One
on BBC One London

with Johnny Ball
A light-hearted exploration of numbers and science. This week Johnny says Hello Listeners
Listening to loud sounds, soft sounds, old sounds and new sounds. Recording some of the first sounds. Investigating drums in the head. Transmitting sounds with a milk bottle and asking a machine to do the talking.
Meanwhile sort this out 'ear: A record costs £2 plus half its price. How much does it cost?**
