Ears convert sound waves into nerve impulses that are sent to the brain. While your ears pick up the sound, it is your brain that does the hard work of making sense of it all. There is much more to the ear than the part you can see on the outside of your head. The middle part of the ear (behind the ear drum) amplifies sound pressure.

Children with normal hearing in both ears generally perform better with auditory tasks and processing sound in their right ear up until puberty. Ears are completely individual just like fingerprints! Yahoo has even explored technology that could unlock a cell phone when held to the ear.

The human ear, like that of other mammals, contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear.
