Ear and Hearing: Basic Principles
How it works
The ear is the sensory organ for hearing and consists of the outer ear, middle ear, and inner ear. Sound waves are picked up by the outer ear, amplified in the middle ear, and converted into electrical nerve impulses in the inner ear. These impulses are transmitted to the brain via the auditory nerve. The organ of balance is also located in the inner ear. Damage to the ear can lead to hearing loss. The most important structures include the auricle, ear canal, eardrum, ossicles (hammer, anvil, stirrup), cochlea, and auditory nerve.
Sound waves are transmitted in the ear via various structures and converted into nerve impulses that the brain perceives as sounds.
