Holy crap. You just blew my mind. "Silence is deafening" makes more than just figurative sense.
From a young age, I've always noticed a light ringing while in extremely quiet places. Not enough to bother me, but enough to notice my ears straining to hear sound.
But yeah, hearing tests cover a very tiny portion of the spectrum. Audiology, in this regards, seems to be completely divorced from the frequencies people hear in real life. In reality, the vast majority of hearing tests barely cover the frequency range of human voice - let alone frequency ranges for music or even tinnitus.
I asked my audiologist if it might be possible to cover a wider range of frequencies and she seemed flabbergasted that someone would even request such a thing.
So, yeah. If you have tinnitus, or music isn't sounding as nice to you anymore, or for some reason bass frequencies sound off - well, you won't find out with a traditional hearing test.
Almost all cases of hearing loss have hearing loss at high frequencies, so they may be able to screen you by just checking at higher frequencies. As far as I know, losing bass frequencies first only comes from specific conditions like Meniere's disease.
I'm perfectly happy with my condition, it's not getting worse and it's not preventing me from doing anything day to day.
What good would getting my hearing tested now do me in the future?
Funny story related to this question, one day in a conference room I thought my tinnitus was just particularly bad, until someone went and turned off some unused AV equipment. The pitch of the electronic noise was identical to my personal tinnitus (and different than someone else's - they commented that it wasn't the right pitch for them).
As I understand it, this is exactly what tinnitus is. Your ear becomes insensitive to a certain frequency, so your brain "equalizes" it, if you will, and over compensates to the point that you're hearing something that's not there.
It had a fast track designation from the FDA, and just initiated Phase 2a clinical studies. Somewhere I read that apparently they will also test its impact in Tinnitus.
I have permanent though currently modest hearing damage and persistent tinnitis of several different sounds at the same time.
it's clear I'm going to have a hearing aid in the coming years as my dad does also, even though unlike me, and he was not a drummer that stood next to speakers in clubs, but he doesn't have the tinnitus.
Getting hearing aids has given me significant relief from tinnitus and if my hearing aid battery dies the tinnitus comes back fairly quickly. It's as if my ear is trying to compensate for the lack of sound.
Of course, there are multiple reasons for tinnitus to occur so your mileage may very, but it's absolutely worth checking out.
