SPEAKER: Your ear has three main parts, the outer, middle, and inner ear. The outer ear includes the pinna, which collects sound waves, and the ear canal, which transports those waves to the ear drum. That's a paper-thin layer of tissue between the outer and middle ears.

Sound waves make the ear drum vibrate and that shakes three tiny bones inside the middle ear called the malleus--

The inner ear translates the vibrations into electrical signals, which are picked up by the auditory nerve, sent to the brain, and interpreted as sound. This all takes place in an instant and lets us hear the sounds around us as they happen.
