the outer ears shape directs the sound inside your head towards ur inner ears. It also amplifies the sound and can help determine where it’s coming from

It’s shape affects the tone of sounds. Given a repeatable sound, it will sound different if it’s in front, behind, or above you from how it interacts with your ear.

Two main factors have shaped our external ear anatomy:

– directional sound filters. The shape of our ears causes certain frequencies of sound to be emphasized relative to others, and this happens directionally – so sound coming from behind us is recognizably different from sound coming from ahead of us.

– storm gutters. Our ears work best when dry, so the external shape tries to keep rain from getting in, and provide an easy path to drain out.
