Why is the pinna important?

Why is the pinna important?

It is the first part of the outer ear’s anatomy that reacts to sound. The pinna is essential due to the difference in pressure inside and outside the ear. The resistance of the air is higher inside the ear than outside because the air inside the ear is compressed and thus under greater pressure.

What happens if the pinna is damaged?

The pinna acts as a funnel to direct sound waves into your external auditory canal and is particularly useful for high frequency sounds. If you were to lose your pinna, you would still be able to detect and hear sounds; however, your ability to localize high frequency sounds would be decreased.
