In mono sound, all sound comes from one speaker or source. In stereo sound the sound comes from two speakers. An engineer creates a stereo "image" which can place sounds in or between each of the two speakers. In surround sound, there are four or more speakers, two of which are behind the listener. This allows for the placement of sounds anywhere between the speakers - front to back, or side to side. Some people may say "we only have two ears," but the next time you hear any sound coming from behind you, you will realize that our brains are wired to hear the would all around us, and that we can tell where sounds come from, even behind us. Surround sound offers a more expanded field of listening.
