Auditory Canal: The auditory canal is a tube-like structure in the outer ear that directs sound waves towards the middle ear.
Eardrum (Tympanic Membrane): The eardrum is a thin membrane located in the middle ear that vibrates when exposed to sound waves.
Cochlea: The cochlea is a spiral-shaped structure in the inner ear that converts vibrations from the eardrum into electrical signals for transmission to the brain.
