The Outer Ear

The outer ear consists of the pinna, the auditory canal, and the tympanic membrane (eardrum).

The pinna

``collects'' sound and funnels to the ear canal;
acts as a filter helping us localize sounds.

The auditory canal

acts as an acoustic tube closed at one end;
boosts hearing sensitivity in the range 2000-5000 Hz (the range of the human voice).

The tympanic membrane

terminates the auditory canal;
vibrates in response to the produced sound.
