Hello, I'm new to the forum. I have had tinnitus (predominately left side) since 1969 as the result of being in a high school rifle club (I doubt that exists anymore), shooting 22's without ear protection, basically in a concrete bunker in the basement of the school. I don't think my Koss headset and rock n Roll helped much either! I was evaluate at the University of Minnesota in 1974 and was basically told there was nothing they could do. I'm not interested in masking it, however, I am interested in solid research. Looking forward to exploring the site.
