How we hear sound

This is a diagram of the ear. I will now tell you how sound travels through the ear. First something makes a sound and creates sound waves. Next the sound travels past the pinna (the big flappy thing) and through the ear canal.Third of all the sound waves hit the ear drum. Next it goes through the ossicles and it is no longer a sound wave. It goes through the cochlea and sends a messege to the brain. Don't worry about the yellow thing because nobody knows what it is!
