    How does a human hear? When an object makes a noise, it sends vibrations (better known as sound waves) speeding through the air.

This sets off a chain reaction of vibrations. Your eardrum, which is smaller and thinner than the nail on your pinky finger, vibrates the three smallest bones in your body: first, the hammer, then ...
