2. How Your Ear Works
Sound waves move
from their source and
make matter around
them vibrate.
The shape of your
outer ear directs the
sound to your inner
ear, like a funnel
directs material from
one place to another.
3. How Your Ear Works
Sound waves
move through
your ear to get
the sound
messages to your
brain.
4. The Eardrum
Sound waves hit a thin
skin called the
eardrum causing it to
vibrate.
5. Three Tiny Bones
As the eardrum
vibrates, it causes
three tiny bones to
vibrate.
