    Now we're getting to the nuts and bolts of what a hearing aid can  
    offer to an aural tuner.

    /While we're at it, can someone with an RCT or TuneLab read some  
    relative signal strengths on the 2d partial of G6 and the 1st of G7.  
    Then does anybody know the point at which a series of pulses turns  
    into a tone? 10 Hz, 15Hz? /


I seem to remember reading somewhere that it was around 30 hz.  Very iffy.

    /Is the point which beat rate is too fast to  
    be unusable for us aural tuners any higher than 12 bps? Maybe that's  
    another measurement for an ETD./

Definatly not.  You can use 15 - 20 bps no problem.  That is to say if 
you are comparing two intervals in which the reference note yeilds 
roughly 20 bps for both intervals... an aural comparison is easy enough 
to accomplish.


    /As pointed out earlier, aural tuning may be the least of the areas of  
    our work affected by hearing loss, and possibly the last to be hit.  
    This thread has barely scratched the surface. At least with water,  
    you DO miss it when the well runs dry./

I'll buy that for sure.  I'll also buy the statement that in the end our 
work is about human hearing and listening... since regardless of how 
well a visual route can get you down the same road or not.... you cant 
appreciate the sound of music without your ears.
