I've found any earplug or headphone option will make my tinnitus worse - sometimes days afterwards.
I explain my tinnitus to non-sufferers as being on the threshold of noise intolerance 24/7.
I'm surprised there hasn't been a lawsuit against any of these companies that expect employees to damage their health just so they can save on floorspace?
Now I have a very faint one that "toggles" once or twice a week and ALWAYS when I wear earplugs.
After ignoring the warning signs and also having an ear infection which I never bothered getting medical help for it got much worse.
It's settled down to a manageable level for me now but heed the warnings, you may save yourself a lot of misery in the long run.
I had a random infection a few years ago and just waited for it to pass. Which it did, eventually, but my tinnitus became much worse afterwards. I'm guessing, because the infection did further damage which could maybe have been avoided?
I can't say whether you should stop wearing earplugs because you may sometimes be in a situation where they protect your hearing. But, for blocking out background noise in an office, they're probably not a good idea? [based purely on my own experience]
I think it's because when you double-stuff like I did, the only thing you can hear at that point is the ringing in your ears (and high heels on concrete floors). My brain seemed to lock in on the ringing at that point.
When I wear earplugs, the tinnitus is more prominent, so after I take them out, my brain is kind of "latched" on to it for a while.
I thought everyone has it.
As an added bonus the obvious rigamarole I have to go through when a coworker taps me on the shoulder makes them more likely to send an email next time.
With earplugs inside noise-canceling phones I still get two layers of sound isolation but have a layer of sound isolation between me and the phones, providing finer volume control so I can add just enough music to finish the job of drowning out loud people around me without hearing damage.
It seems the best solution is to not have loud people around.
Thanks though.
