Where is pinna found?
The outer ear consists of the visible portion on the side of the head, known as the pinna , and the external auditory canal (ear canal) . The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) .
What part of the ear is the pinna?
The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.

Can you live without a pinna?

Where are the pinna located on the head?
The pinna are the visible parts of the ears located on the outside of the head. Pinna, derived from the Latin word for feather, are what a casual observer usually refers to when they are pointing to your ears.
