A non-invasive system and process for converting sensory data, e.g., visual,
audio,
taste, smell or touch, to neural firing timing differences in a human brain and
using acoustic signals to generate the neural firing time differences. Data related
to neural firing time differences, the acoustic signals, and a user's response
map may be stored in memory. The user's response map may be used to more accurately
map the calculated neural firing time differences to the correct neural locations.
