Hello all, A year and a half ago, I went to sleep without any hearing problem and woke up about 3 hours later with severe deafness (-80Db on most frequencies) and Tinnitus in my left ear. Thanks to the American Tinnitus Association, I have a recording of my Tinnitus. When I play it with headphones on my Ipad, I set the volume to about 3/4 of maximum which is about what I hear in my left ear. (I wanted to post a link here but SPAM protection prevents me from doing this so I attached to the message) You can find the mp3 file on the American Tinnitus Association in the section <sound of tinnitus> the screeching sound It's nice to have this mp3 because people, especially family have trouble understanding what it is to live with T and Single Sided Deafness. They usually don't last a minute. I explain to them that this is my new 24/7 silence. I now wear Phonak CROS hearing aids to at least be able to hear sound from my left side even if it is injected in my right ear because my left ear cannon be aided. A few weeks ago, I went trecking with my kids and while we were near a waterfall, my daughter spoke to me from my left side and I suddenly could hear. I removed my hearing aid and CROS system and my son spoke softly in my left ear and I could hear. As soon as we left, I could hear nothing more than my usual companion, the screeching tone. I had an appointment with my ENT today and I told him about this. He had never heard about such a thing and neither had the audiologist. Neither one seemed to have interest in exploring this thread to my earing. I was wondering if anyone with SSD and T has ever experienced something similar and if it is worth pursuing this hint in my condition. Thank you.
