A few years ago I would take a chair, put it in the middle of a quiet room in the quiet part of the day. I did this purposely - in other words, the chair, the room, the time.. on purpose. Then I sat in the quietness every day for 1/2 hour listening beyond the T for quiet. It's difficult, like holding a hot pan. It worked for me for a while. As time went on, I was noticing the T again. I had hopes that this exercise would work. It didn't after a while. I thought hard about what to do next. I joined this forum, that was the most important thing I've done for my T, ever. With 40 years of T behind me, I was still bothered a lot by it.
Someone here on the forum explained there is a technique that forces the habituation. I liked that idea. Even before I read this, I felt there MUST be something I can do. The idea of waiting around for habituation did not click with me. So I started gauging my reaction instead of my T. No more describing it, listening for it, fearing it, etc... Now when I hear it I immediately ask myself what my reaction is. At first, I'd answer, "I'm scared and bothered." (Notice there is NO mention of the T sound). Now, months later, I only answer, "There it is, I could care less." An honest answer is required. Absolutely no description or measurement of the T is allowed. After a while, a short while, it seems I grew tired of telling myself how I felt about T and the T went away. OK, I hear it right now, because I'm talking about it. I only have to measure my response once or twice a week now, compared to the first week when I was doing this about 30 times a day. I was VERY surprised and happy to have the T melt into the background, or the blackness, or wherever it goes. And for the first time in a LONG time, I began to feel happy and relaxed.
I've had T since the mid 70's thanks to loud music.
