I wonder about a genetic component. I've had the "sound of silence" for as long as I can remember. I don't remember how old she was, exactly, but my daughter confirmed she was experiencing something similar at a pretty young age (under 5 y/o). We were always very careful with her hearing (to the point that we had very small earmuffs we'd have her wear in potentially loud situations), so I don't think it's the result of physical damage.
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.
I've had tinnitus since my teen years, half a century ago. At least, what I normally hear is, I assume, tinnitus, but it comes in two forms. There's a constant sort-of grey noise, not too loud (definitely softer than people talking in the same room), which wavers in amplitude over a sub-second period. The more annoying form is a pretty pure sine wave, much louder, which thankfully is more infrequent. Not really sure if that quieter form is something everyone gets, or an actual tinnitus form. Anyway, after 50+ years, it's not a big deal to me.
I'm in the same boat for the most part. Always had tinnitus, for as long as I can remember. Doesn't bother me at all.
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".
Its the same for me. Its always been there. I've also done a lot of activities over my life that make it worse, like playing the drums, attending very loud electronic music parties, and motorcycling without earplugs. It's just a low-level background sound that is part of my life, and I'm lucky enough to be able to tune it out most times. But reading this post and going through this thread has made it a lot worse.
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.
Same for me, is it weird I'd go so far as to say... I like mine? I like the name "the sound of silence" for it - I kinda feel like I use it as a "plane" to think on top of somehow or something. For me it kinda...whirrs up almost, till I'm fully enveloped by my thoughts and imagination, at that point the tinnitus is gone and I'm in unbridled thinking mode,I quite like the whole experience personally. I'm scared it will get debilitating like others have described, but it's never bothered me.
Never bothered me much. Its much worse now at times. Still doesnt bother me much
