How do we actually hear?

The sole purpose of your outer ear is to collect sound. It sends the sound down your ear canal to your eardrum. The eardrum starts to vibrate which causes the 3 bones (the 3 smallest bones in your body) in your middle ear to vibrate. The vibrations are transferred to your inner ear where millions of tiny hair cells respond and send the information to your brain. Your brain then processes and makes sense of the information it received.
