I have had tinnitus since I was a little boy, maybe from birth. It sounds a lot like katydids. The sound pulsates with my heartbeat. I also hear a low tone that only happens when all is quiet. It kind of sounds like the hum of a refrigerator running. I'm hearing both sounds at the same time as I type this. And if I hear a loud noise close to me, like a truck horn, I'll wake up in the middle of the night, for the next couple of nights, with a distinct tone in my ears like the tone TV stations used to play when they went off the air for the night. My tinnitus has been getting worse now that I'm in my 50's. I've become sensitive to high pitched sounds, like pots and pans clanging together. Loud, high pitched female voices are also a problem for me. Some days my tinnitus isn't very noticeable. Other days, it's disturbing. I hope it doesn't get so bad that I eventually spend my days in torment and have to go on sedatives. I try not to think about that possibility. I went to an ear doctor recently and he recommended "Lipo-Flavonoid Plus." I hope it helps.
