As a sound wave moves from the source to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport. Each individual particle pushes on its neighboring particle so as to push it forward. To accomplish this, sound waves require a medium a solid conductor areas of high and low energy
