But, the deaf person would have to be very observant. My SAT III has trouble, especially in the 1st octave, of staying on the right note. Even I have had to retune several notes when I noticed I was tuning the wrong one. But, even that alone, is not what makes a piano tuner. Listening to clicks, buzzes, scrapes, and other extraneous  noises, and of course, taking care of them, are all part of "tuning" a piano. Wim </HTML>
