At one point, I tried forcing myself to get used to tinnitus by wearing ear plugs 24/7. My logic was that I found T to be the most disturbing when I would be shocked by it when trying to sleep in a quiet room. I thought that if I were to listen to it throughout the day, it would not be so disturbing in the evening. It worked - eventually it became easier to fall asleep. However, I was doing HBOT treatments at the time. They would look into my ears before each session. I was told that I was getting an irritation on my eardrum. I suspect this was happening because earplugs prevented my ears from being aired out, promoting the growth of bacteria in my ears. So perhaps this is not a good approach. On the other hand, one could wear earplugs for one hour, followed by no earplugs for the next hour. This ought to prevent ear problems, while forcing one to confront one's tinnitus, and eventually to get used to it...
