I hate that little hiss. Mine is pretty tame but not so tame that I don't notice it throughout the day. If I listen for it I can always hear that little ssssssss..s.sss.s..sssss....sssssssssss.ssss and of course it's not steady, more of a random hiss, in and out. I've been "aware" that it's a condition since early 2015 but I've had the tone and this forever. Not sure if it got worse or if I just finally noticed it out of being alone and bored. I deal with it okay but now and then it just gets on my nerves. I wish I could just poke a fork in my ear and put out the flickering fuse. Maybe someday medicine will essentially let me do that. In the meantime I just try my best to forget about it. I used to write it off to the sound of lights around me or computers etc. I try to do that now too just for the mental relief when I start to focus on it. Anyway, just venting. My continuing best to all of you of course, my brethren in hiss and tones.
