I had a problem like this about 2 months ago. I was experiencing something like squaking, sine at 19-20kHz. It was terrible, I couldn't stand it. I went to an ear specialist and he made something like deep ear-washing. But after that, I still heard that terrible whistling in my ears. After a few days, I forgot I had something like tinnitus - it almost disappeared. Sometimes, I hear it, sometimes not. I hope it would not get any worse... anyway, I am 18 and I have no clue, where could I get it from... I listen to my headphones at fairly low volumes (but I didn't use to
). Now I am much more careful about my ears, I dropped my normal listening volume and I also care about the listening fatigue. Hope it's still not late.
Anyway, it's a surprising result for me that almost 58 per cent of head-fiers are experiencing tinnitus
PS : When someone turns on a CRT TV, I hear that CRT screen squeaking at something like 17-18kHz... and sometimes it's kinda annoying. Is this ok ?
