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...
- Cut off a piece of two foot string (2').
- Using a rubber band, attach a metal spoon to the midpoint of the string.
- Wrap the ends of the string around your fingers.
- Rest your fingers in your ears (don't stick 'em in too far or you'll poke your brains
- 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.
