I think its more appopriate to post tinnitus related topic in the general forum rather than in the headphone forum.

I can hear ringing in my ear a couple of seconds in a whole week. the sound is harsh and resembles the harsh sound of a improperly tuned radio. treble sometimes could be harsh too, easily fatiguing my ears. so it makes me wonder if a person could not hear treble very well because of tinnitus..

here is a letter from a musician who has tinnitus and hearing loss at the upper end...

if this is true. no wonder some head-fiers who have wild tinnitus demand headphones with strong highs...

and, I also wonder whether a certain range of sound (bass, mids, treble) harm the hearing or not.

Tinnitus caused by excessive volume levels can cause damage at all pitches. It's not related to the pitch, it's related to the decibel level.
