If you cut off your ear can you still hear?

Answer 1

No, because your ear is part of your eardrum , and without your eardrum you cannot hear ** Actually the above is not true. Your ear on the outside can be completely removed and as long as the ear canal is still open you can still hear. The eardrum is far inside the ear canal that it would not affect your hearing. You would look funny

without the outside of your ear though.

Your ear, on the outside is used to channel, amplify sound to your eardrum. That's why holding your hands behind your ears amplify sounds so much. So it's not needed to hear, but it dramatically helps with amplifying sounds, and also with determining direction of sound. Without it you'd be one confused person.

Answer 2

The part of the ear you could cut off is called the pinna.

What function does the pinna serve in the ear?

“The purpose of the pinna is to collect sound. It does so by acting as a funnel, amplifying the sound and directing it to the ear canal. In mammals like cats and dogs, it is obviously highly directional, but even in humans, the pinna functions as a directional sound collector.”

It does help in locating the source of a sound.
