I can certainly see where sound could be used to tell whats happening in the market, I do something with the ES like that. But historical charts would have to be a problem.
Market Sound. This is a computerised voice that speaks the quotes for futures markets. Gets noisier as market gets busier. It used to be free but looks like it costs now. http://www.cme.com/dta/rt/equotes/mrktsound2389.html
I've attended several times chess sessions with blindfolded players who were playing simultaneously against 10-40 players. And in most cases they won all or 99% of their games. Blind people develop , by nature, an extraordinary memory. If you would apply this to trading I would recommend a squawk box like www.marketvu.com or others, where you have real time (voice)coverage (free) of what's going on in the market. Good trading TFD

Also nociced over many years some medical doctors study much better than others; Dr. Reginald Cherry ,M.D.,of Houston Texas also seems to enjoy his reearch .
Just read an interesting (fiction) book about a blindness epidemic suddenly striking a European city. Blindness by Jose Saramago. Very interesting read...
