We just learned about the Outer Ear.
Part of the outer ear is called the Auricle or pinna.
This is the part of the ear that you can see outside of your head.
The shape of the ear helps bring sounds in and make them louder, and it can also help filter out sounds that are too high or too low for the human ear to hear.
