Question: What is Surround Sound?
Answer: From the Ambisonic Surround Sound FAQ maintained by Martin J. Leese: Ambisonic or Surround Sound is a set of techniques, developed in the 1970s, for the recording, studio processing and reproduction of the complete sound field experienced during the original performance.
Ambisonic technology is based on a meta-theory (a theory of theories) of sound localisation developed by the late Michael A Gerzon when he was with the Mathematical Institute, University of Oxford.
