How the ear works step by step?

1. Sound transfers into the ear canal and causes the eardrum to move.
2. The eardrum will vibrate with vibrates with the different sounds.
3. These sound vibrations make their way through the ossicles to the cochlea.
4. Sound vibrations make the fluid in the cochlea travel like ocean waves.
