Precisely

Pink noise has even power distribution per octave. So I guess what I need
is just a small bandwidth of "random" noise, whether it's pink or white
probably won't matter. I will be doing some testing shortly, but I believe I
only need 1/3 octave centered on the tinnitus frequencies, as you described
above.

No doubt impossible for "normal sized" hearing aid. What I have in mind is
a pocket module that can help make my life a bit more normal again :-)

Thanks, I'll need it. Jim
