Jibs, Reason is not too difficult once you get into it, but it does require a little knowledge of audio kit. I can send you the individual tones I've made - 400Hz up to 16000Hz in 100 Hz jumps - and the patch for the NNXT. I'll have to e-mail though as the audio samples are 28mb in total, send me a contact and I'll sort it.
Unik, I wouldn't like to produce tones that high as you have to ramp the volume up slightly as you move up the frequencies even though I will synthesise at the same level, Jibs is right that I think it will impact on your hearing, plus the tones will be virtually pitched the same at that level.
Sisko, we may still be able to do something for broader range tinnitus, experimentally, I can play multiple tones at the same frequency range as the tinnitus. For example if you can identify that your tone is at 6Khz and about 1Khz wide we could try playing all 10 tones in a 1Khz band at the same distances specified. It would be worth trying to see how it works and I'd be happy to synthesise them for any experimentation. After all, that is all they do in their research. They start with a theory, test it, modify it, test again etc. We can do that here just as well, if not more efficiently, as we aren't dragged down by the need to create something that can be patented and profited from. It's just playing with sound.
