A New Problem ???

I’ve mentioned before that noise is a problem for me.   It seems there is more to just noise than I realized.   I just started “trying” to listen to an audio book using my iPod earphones. I was on a plane where there were many others sounds and conversations.   Even though the sound coming through the earphones was very loud, I had a very difficult time focusing on what was said.   I had to close my eyes and really concentrate.   After a few moments I experienced something unusual where I felt there was a back and forth sensation going on in my head.   It’s the same kind of thing I feel when I try looking through binoculars.   What is this?   Have any of you noticed something like this?   The experience created a lot of fatigue for me which often includes my eyes watering a lot as if I’m crying.   It was not a great experience (but I’ll keep trying).
