A system was developed for stereophonic presentation of information (3-D sound) over high-fidelity headphones. The purpose was to reduce the pilot's response time to a localized threat. Physical parameters permitting the localization of sound are reviewed. The technique used to collect a subject's acoustic filtering characteristics is also described. Space simulation of a monophonic sound is presented, the purpose being that the sound be heard as coming from a given point in space. The first steps of a physical validation of the synthesis are presented.
