2. Transmission processes in the ear

3. The sound wave that arrives at the ear is a pressure wave The ear converts sound waves into electrical nerve impulses, similar to a microphone

4. The outer ear, or ear canal, carries sound to the recessed protected eardrum The air column in the ear canal resonates and is partially responsible for the sensitivity of the ear to sounds in the 2000-5000Hz range The middle ear converts sound into mechanical vibrations and applies these vibrations to the cochlea The ear reduces a sound's amplitude to avoid damage.

5. Inner ear consists of the cochlea the cochlea converts sound waves to electrical signals They do this by the sound waves propagating through the inner ear, causing fluid waves, causing a movement of hair cells. The hair cells convert the mechanical energy of the fluid waves into electrical signals, which are then transmitted for the brain to interpret it.
