Sound

Sound Waves from the bell travel through an area of low pressure

The sound waves reach the outer ear and travel to the eardrum which vibrates sending the sound waves on to the middle ear. The middle ear contains the 3 smallest bones in your body - the hammer, anvil, and stirrup. They amplify (increase) the vibrations and send them to the inner ear.

How Sound Travels

What is Sound

The sound waves are pushed closer together creating an area of "compression".

The cochlea is shaped like a snail shell and changes the sound energy to mechanical energy that travels through the nerves to the brain. The brain then makes sense of the sound.
