When you listen to music, when its waves of sound collide with your ear, you don't hear a wall of sound. A great deal of information might travel in a sound wave and, if that sound wave were actually a giant wave of water rushing onto a beach, you might expect to feel it as a big shove like any other big wave of water coming in from the ocean. Except that's not what happens when this particular wave hits you. Standing there ankle deep in the surf, you brace for it to crash against your body, but when it does arrive, it's not a "hit" at all. Instead, you feel a hundred different things at once, all on different parts of your body. Some places it's a cool brushing, others it soft slap or the feeling of a light sunburn. And then the wave is passed.
