This is how we hear! (ES)
Sounds/noises hit the ear in the form of sound waves. What happens then in the ear?
The outer ear (pinna) collects the sound, which is then conveyed via the ear canal to the inner ear. Here the sound is amplified because of the small diameter of the eardrum and of the structure of the ossicles (malleus, incus, stapes). The sound waves are transmitted to the cochlea, where they are turned into electrical signals. These are then conveyed via the auditory nerve to the brain, where they are recognized as words and understood.
