Sound is actually nothing more than moving air and the way we perceive that moving air with our ears. Now you may be saying "Wait a minute Reeko... sound is made by moving air?". Sure. Let Reeko explain...

  1. Cut off a piece of two foot string (2').
  2. Using a rubber band, attach a metal spoon to the midpoint of the string.
  3. Wrap the ends of the string around your fingers.
  4. Rest your fingers in your ears (don't stick 'em in too far or you'll poke your brains out!).
  5. Standing next to a table, rock your body back and forth so that the spoon taps against the side of the table.

What do you hear? When the metal spoon taps against the table, it sends a vibration up the string, through your fingers, and into your ears. Your eardrums pick up the vibrations and send them to your brain where they are translated into what the brain perceives as sound.
