ABCNews reports on a British startup company demonstrating what could be the next step up in cellular sound - surround sound - based on the science of "psychoacoustics." The article explains in great detail how it works:

"Engineers at Sonaptic Ltd have developed a new set of chips and software that can reproduce 3-D sound that seems to encompass the listener. The technology, says Sonaptic's managing director David Monteith, is based on the science of "psychoacoustics."

"It's a digital process of using complex algorithms and calculations to trick your brain into believing it is hearing sounds from all around," says Monteith.

To achieve this sound effect, psychoacoustic designers study the mechanics of human hearing. "They look at the shape of the inner and outer ears, how the head and skull conducts sound, and how all this is interpreted by the brain," says Monteith". [...]
