Never bothered me much. Its much worse now at times. Still doesnt bother me much
However, for the past 3 or 4 years, during spring, I get much worse tinnitus in my right ear for a couple weeks. It appears to be caused by some kind of blockage in my inner ear due to the inevitable viruses we catch during the winter. It's louder and a lower pitch (around 3 kHz, unlike my 10+ kHz normal one), and even though it's not the first time this happens by now, it's still extremely annoying. It's harder to just ignore, and my mind immediately starts thinking "what if this lasts forever?"
So I can imagine that for those who develop tinnitus at adulthood, it can cause a lot more distress, because they lived the "before".
You might try alergy meds (pills or nasal inhalers) to try to clear that up. I wouldn't expect it to do anything for your chronic tinnitus though.
I'm sitting alone in a quiet room typing this and I've got a cacophony of >12kHz whine going in both ears. The left is slightly louder and lower than the right. It's not debilitating but it would be really neat to hear actual silence once in awhile.
I played w/ doing hearing range tests on myself and my friends using an old NEC V20-based laptop during my high school days (mid-90s). I wrote a little BASIC program that played sounds of increasing frequency and asked you to report if you could hear the sound. Sometimes it indicates it's playing a sound when it isn't. By playing (or not playing) sounds repeatedly I would build up a "score" for the user's high frequency hearing response.
I have notes showing I could hear between 16 and 17 kHz back then. Today I struggle to hear more than 12 kHz. Interestingly, my tinnitus presents frequencies high than I can actually hear now.
Interestingly, my five-year-old was complaining about ringing in her ears being distracting at bed time, so I wonder if it is genetic too.
