Hearing Human senses - hearing

Fact file

Ears pick up sounds waves - they convert vibrations in the air to electrical impulses that pass to the brain. The brain processes these impulses and we 'hear' sound.
The ear contains the smallest bone in human body - the stapes.
Loudness is measured in decibels, the louder the sound, the more decibels.
As we get older we lose our ability to hear high pitched (squeaky) sounds.

Activity:

Sometimes our ears play tricks on us, particularly if you cannot see where a sound is coming from. With a partner, take turns making mystery noises and identifying them. There are lots of different noises you can make, clap your hands, click your fingers, scrunch up a paper ball. Make sure you have your eyes closed when it is your turn guessing.
