Yes, I did get my hearing checked with an audiologist. The only thing she could do was recommend tinnitus-canceling hearing aids which I decided not to use since my hearing loss is mild to moderate.

I guess being highly sensitive does mean I'm going to experience it more, not to mention the increase in artificial EM frequencies.

I know that correlation doesn't always mean causation, but the first time I experienced it, I attended a channeling evet and sat right next to the channel. Maybe I experienced some kind of energetic opening. Anyway, it's always been at the back of my mind as a possible cause.
