So we have no idea why I got tinnitus. No exposure, no loud sounds. Never been to concerts, don't like any noisy environment. I did listen to an iPod with ear buds for several years in med school and I've just assumed that was the set up. So I noticed about 2 months ago that my microscope at work emitted a super high pitched sound that is quiet but constant. The tech could hear it and thought it was electrical sounds from the main board of the scope. To fix it we have to order a board from Japan and it was gonna cost thousands so I was just like I'll just deal with it. And I've come to ignore it. We'll I just realized the other day that it is the exact sound I'm hearing with my T. And it emits from the left of my scope which is the ear that is affected. It is just bizarre. The tone is identical. Even down to the electrical hiss. However, I have to say when my T first hit it was lower and took a few weeks to level off to the tone it's at now. Maybe it is just mimicking the sound? Often I've been thinking I'm hearing the T in both ears when I'm at the computer and my right ear is to the left of the scope. Realized today it was that sound the scope was making. How weird is this?
