THANK YOU for your replies and suggestions. I mapped out my tinnitus sounds
today using some sound analysis software. It appears that the three main
frequencies that are loud as hell seem to be centered around 11.2 kHz, 11.8
kHz and 13.8 kHz. The higher frequency tone is so high when generated on
the computer that I can barely hear it through my ears, but it is screaming
in my head.

Tests with a wide-band white noise generator are, so far, unsuccessful in
masking the noise. Maybe it's not wide-band enough, the speakers may not be
good enough, or perhaps my ears just aren't responsive enough to let the
masking noise in at the high freqs. I am doing more experiments to try and
find out what sounds might mask the noise.

The "shooter's protection" lead is a good one and I have located an
amplified headset that allows max 82 db into my ears while providing 15db or
so of amplification, so at least I'll be able to hears plays and concerts a
bit while figuring out a plan.

For now I am going to take the simple route of creating my custom-bandwidth
white noise as a high-bitrate MP3 using various tools on my pc, then using a
miniature MP3 player to pump it into my ears full-time. The treatment folks
so far want over $800 U.S. for a custom sound generator per ear, which seems
a bit steep.

Thank you all for your help and suggestions. They have given me many new
ideas and directions to pursue, (one of which is to buy a DSP kit to start
learning).
