I've experimented with tinnitus "conditioning" treatment, it does work.
Thanks for the understanding and I guess you've forced me to do something "scientific". Using an iphone 4 with iOS6.1.2 and FreqGen by William Ames, (which, according to a couple of the reviews, appears to test accurately), through a pair of DT880/32, I get:
Lower limit 23 Hz, upper limit about 14.5 Hz, naturally neither was a the same level as at1kHz, but then the phones weren't corrected for flat response either, so some error there as well, but ballpark is probably OK at this stage.
The tinnitus ringing in my head seems to be at about 7.5 - 8.5 kHz. The voices however appear at random frequencies.
I've tried a few OTC remedies, they don't work for me, not even slightly, but if you have any recommendations, no problem with trying them out.
As for the spectral content, I can't accurately tell you. There is an instrumental track on James Taylor, "One Man Dog" which uses acoustic bells, on "good" phones the track reproduces with no problem, on "bad" phones the whole track can "ring". But at a guess I'd have to say in the range of 1.5 - 6.5 kHz.
If it helps, at this stage, I'd group as "good" phones that I've owned, AKG K340, (the old ones, not the newer ear buds), DT 880 & 990, Koss ESP 9 and 950, Stax SR-3/SRD5, and SRXMkIII, PWB Electrostatic and Moving Coil, (yes I owned both at one time!) and Wharfedale Isodynamics. And I accept your premise that any/all could have been ringing at inaudible levels.
Phones I'd call "bad" are AKG 701,(slight), Senn HD 580, (slightly worse), a pair of electrets from either Micro-Seki or Audio Technica, can't remember now, (worse), Sony MDR somethings, and the already mentioned HE 500. Very disappointed in the latter, I really wanted to like them. I'm sure there are others I've forgotten, because I didn't own them for very long for obvious reasons.
I'm not sure an eq would help, I think I could end up throwing the program out with the ringing. It also doesn't seem to be an open back/closed back issue.
Anyway, that's it.
