Explanation:

The auricle (outer ear) collects sound waves. The cochlea (inner ear) converts sound into electrical impulses. The tympanic membrane (eardrum) vibrates in response to sound waves. The Eustachian tube regulates pressure in the middle ear. The optic nerve is related to vision, not the ear.

Answer:

1. Auricle: Collects sound waves
2. Cochlea: Converts sound into electrical impulses
3. Tympanic membrane: Vibrates to sound waves
4. Eustachian tube: Regulates pressure in the middle ear

(Optic nerve is not matched to any ear part)
