Hello all, I developed a strange tinnitus that is freaking me out today. Every time I hear any sound in the environment, that sound gets converted into a single tone around 5-6 khz. That is, doesn't matter if it is a person walking, a bird chirping, or me talking. Every sound is replaced with an tinny "EEEEE!" sound in my left ear! Note that if I sit completely still this T tone does not exist, it is only when I am presented with a sound stimulus. It all happened after eating in a cafeteria with earplugs in. As soon as I took the plugs out this is what resulted. There is no way the noise was loud enough in there to damage my hearing, as I have sat in there multiple times with the same plugs and no problems. I really don't want this to be permanent and to not hear natural sounds! Every footstep I make feels like I am ringing a bell! Anyone have something like this or know how to alleviate it?
