The outer ear collects and directs sound waves into the ear canal, which leads to the eardrum in the middle ear. The middle ear contains three small bones that transmit sound vibrations from the eardrum to the inner ear, which is filled with liquid. The fluid in the inner ear moves in response to the vibrations and stimulates hair cells, which then convert the mechanical energy into electrical signals that are sent to the brain. Therefore, the outer and middle ear use air as the medium to transmit sound, while the inner ear uses liquid to transduce sound waves.
