Sound paints the scene for the mind in a far more subconscious way than visual input ever can. Sound tells the player whether they're outside or in an underground cave, beside water or on top of a mountain. True 3D sound tells the player if the water is on their left or right, if the door that is opening is above them or below them, or if a freaky alien is coming up behind or in front of them. The trouble is most computers have only two speakers, both in front of the player. This makes it hard to get a sound to realistically come from behind the player's head.
True surround needs five speakers.
Two in front of the player two behind the player and one directly in front of the gamer for the center channel. While this setup is ideal for optimal sound, there just aren't many gamers who have a full five-speaker compliment for complete surround sound. That's where my idea comes in. I have taken the concept of speakers all around the player and reversed it. I attached this comfy 80's style leather office chair to a washing machine motor.
