When my T hit me hard in 2012, I would've preferred to be stone deaf than deal with the frequencies screaming in my head. A low-pitched hum in my left ear was unbearable if I was anywhere remotely quiet. I even remember thinking if it weren't for my family, I'd chose the afterlife over this hell. I'd experience T, H and even a weird, distorted type of T brought on by certain noises, like a motorcycle exhaust. And as a musician, avoiding noisy environments is not an option for me (but using IEM's at low volume helps). Out of fear, I tried vitamins, Keppra, and all the snake oil BS people are selling out there. My T was at an 8 out of 10 scale. Nothing worked.
About 2 years ago, I noticed kind of out of the blue, that my low hum was getting quieter, to the point where it was getting really easy to ignore. However, my high-pitched T seemed to be getting louder. But overall, I'd say my annoyance scale dropped to about a 5.
Fast forward to 2019. I don't know if the brain just "figures it out" and turns down the gain on the lost frequencies, or what the body does, but my annoyance level is a 1 now! The low hum is completely gone, and the high screams or nothing more than a quiet whimper now. I can even sleep without white noise, although after so many years of sleeping to a fan, I'm too used to it to stop.
It really took about 7 years to go from hell to back to "normal", but it really can happen!! I'm convinced that's why we don't see of the folks that used to frequent this site back in the day. I still lurk here, but don't post much. I don't really think about T anymore, which has been life changing.
I know the fear the new / newer sufferers are going through. It's awful and debilitating, but things can get better, it just takes time. Also, habituation (believe it or not) is a real thing. And stay positive on the hearing loss treatments coming along. I have no doubt it'll help T sufferers with NIHL.
Stay strong out there!!
