What is Sound?
Sound is a form of energy. It is different
vibrations that are traveling through air which
people can hear with their ears. Sound waves can
travel through all matter gases, liquids, solids
and plasmas.

How We Hear Sound
Sound waves are collected by the outer ear travel
down the ear canal to the eardrum. When the sound
hits the eardrum vibrations are made. Then the
three bones in the middle ear -- the malleus,
incus, and stapes (hammer, anvil and stirrup) --
move. Fluid in the inner ear transmits the
vibrations into the hearing organ, called the
cochlea.

• The Ear Canal
• The Cochlea
• The Stapes
• The Ear Drum

Go back and review how we hear sound and try the
question again.
