Travel Inside the Ear

When the sound
waves reach your ear, you know you’ve heard a
soft sound or a loud sound. The sound passes through the
outer ear and is funneled into the middle ear where it
bounces off the eardrum and is amplified through
three tiny bones: the hammer, anvil,
and stirrup. These are the smallest
bones in your body. Together, they are
smaller than an orange seed. It then travels into the inner
ear, which is filled with fluid; through the cochlea; and passes the
vibration of the sound through the hair
cells to your brain. ♪ Music ♪
