My hearing was tested by an Audiologist and my hearing was normal.
The “sound” I observe is high pitched. Using a tone generator I matched it to around 16,500 Hz. Interestingly, if I play that tone I get temporary relief on the order of 2-10 minutes.
As far as I understand my tinnitus is the result of something going wonky with the signal processing in the brain.
If you’re suffering from tinnitus for the first time it’s important to remain calm. There is defiantly an amplifying effect from the psychological aspect of tinnitus. Eventually the body will “habituate” if it does not go away. It took me around 3-6 months to be able to ignore it. During the day I rarely hear it. At night a little more. Playing sounds at a low volume on a Bluetooth speaker helps. For example on Spotify an artist called “TMSOFT” has good stuff. In the day I’ll listen to jazz or lofi.
It’s important to protect your ears. iPhone has a hearing protection feature for headphones and I have it on the lowest setting. I would avoid in-ear headphones. Use hearing protection at concerts.
