Sound waves enter the ear through the auditory canal and vibrate the eardrum. These vibrations are then converted into electrical signals by tiny hairs in the cochlea of the inner ear. The brain processes these signals which travel to it through the Eustachian tube to allow for hearing and balance.

1. Ear The Organ of Hearingand Balance Sound waves enter the ear through the auditory canal and then travel through the eardrum, where they are converted to vibrations. Millions of tiny hairs in the inner ear’s cochlea convert the vibrations into electrical nerve signals, which are sent to the brain through the Eustachian tube for processing.
