Never bothered me much. Its much worse now at times. Still doesnt bother me much
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.
