I'm a 70yr old male who, for the past several years, has been acutely aware of an annoying, unvarying and sometimes unnerving high pitched, hissing sound in the right side of my head. I've recently undergone stapedotomy surgery in my right ear, and am anxiously awaiting my first post-op appointment. My tinnitus had become more pronounced as the hearing in my right ear worsened. My best estimate of the initial onset of both hearing loss and tinnitus was sometime in 2007-2008. I have been studying ear physiology in general and tinnitus research for the past few months. I'm now retired and have an extensive background in communications and industrial electronics.
