Holophonic Sound. Developed in the 1980s by Hugo Zuccarelli, Holophonic Sound uses the same “multiple exposure” premise as that used to create holographic images (“holograms”). Holophonic Sound is produced by recording the interference pattern generated when the original recorded signal is combined with an inaudible digital reference signal. The recorded sound produced is so realistic, some people claim they can smell sulphur when they listen to a holophonic recording of someone striking a match! It appears that Holophonic Sound waves stimulate our brains to reproduce very realistic and truly three dimensional sound within us, thereby stimulating other corresponding responses that our brains expect to accompany the sound, (like scents or other sensations).
