I get residual inhibition from special frequencies I found but not from CR, I need to play 2400, 3600, 4800, 5600, 6300, 7600 tones, interesting 4800 is the octave above 24, 76, the quint above that, natural harmonics
You may try this basic pattern of 13-14kHz followed with 30sec pause, see if it helps, this works for my tinnitus, but it could be that your tinnitus is specific.
