The outer ear

The outer ear serves to localize, collect, lead and enhance sounds.

The sound waves are collected at the Pinna, which is the externally visible part of the ear. The Pinna then directs the sound waves to the ear canal.

The external ear canal transmits the sound waves to the eardrum.

The curvature of the ear canal prevents the gathering of water and other foreign materials in the canal. The outer ear also serves a protective function, protecting the middle ear mechanism from external physical harm.
