It's bandwidth-related.  I hear up to about 6 KHz, then the sound drops off to 
nothing.  It's the limits of the hearing aids.  No matter what I use, it's 
going to sound the same to some extent if it goes through the hearing aids 
first (through air or wires).  I use a stereo cord that runs output directly 
from the headphone jack on a soundcard to my hearing aids, which is much 
better than headphones, actually, because of how the headsets tend to not be 
designed for a tiny microphone positioned above the ear (hearing aid).  This 
is essentially a $2,200 pair of headsets, if you look at it this way.  ;-) 
Anyway, I don't understand what sounds are like above this point.  I don't 
know what something at 10KHz sounds like (I've never really heard it, so I 
don't have a concept of sounds above this point).

One possibility would be to design an isolating room with speakers capable of 
producing a minimum of 123 db across the entire frequency band at any point 
in the room.  Then I can adjust downward the frequency spikes and pull up the 
frequency holes I have trouble with.
