I'm a teacher so I'm talking quite a bit during the day. Unfortunately the behavior of my student isn't always the greatest and sometimes I have to raise my voice to get their attention. Over the years I've curbed this bad habit but sometimes still I have to. Anyway...when I do raise my voice I will hear crackling in my ears. Has anyone else experienced this? Before I had tinnitus this has happened although only when I was raising my voice and only when I started teaching (loud sirens will do it too). Sometimes I think this helped trigger my tinnitus.
