HOW SOUND WORKS
When the source of the sound vibrates (moves quicklyback and forth), the air around it moves back and forth too.The movement passes through the air as sound waves.When these waves reach the ears, they make the eardrum vibrate. The eardrum is a piece of skin that is stretched tightly across a tube in the ear. The vibration of the eardrum makes tiny hairs in the inner ear vibrate as well.
The movement of these hairs causes nerve cells to send signals to the brain, which interprets them as sound.
