I had a middle ear infection some 30 years ago. It blew my eardrum, which at the time was a good thing, as the specialist said had it gone the other way he'd have met me, unconscious, on the operating table. The blown eardrum eventually closed up, but ever since I've had tinnitus. Other than using the phone on my other ear it had little impact on my life, it went louder and softer every so often, but I basically ignored it!
Some 6 or 7 years ago the tinnitus got a lot louder and really affected my ability to hear the TV, conversation or much else, except the hiss. So after chasing back and forward to the ear clinic, using an in ear white noise generator and night-time bedside white noise generator so I could at least go to sleep, they did another hearing test and 'tried me' with a hearing aid. Suddenly the tinnitus reduced (It's still there but back to the earlier level.) I could hear the TV and my wife speaking to me,* and for the first time in ten years, out on my bike, I heard Skylarks! The latter reduced me to tears!
My advice is to ignore** tinnitus that has been diagnosed and checked, unless it stops you hearing normally. If it does then seek help. My hearing aids boost sounds in the higher frequencies (I'm pretty much deaf above 4000Hz.***) and means I can hear what mu grandchildren say.
* Everything has a down side!
** After diagnosis and if it's merely there rather than affecting your ability to hear. My bedside noise generator is and has been since day one, a boon to sleeping normally.
***Coincidentally, or not, my tinnitus hiss is at exactly 4000Hz. I suspect it's my ears trying to boost the input signal at the point where it gets no noise coming in!
