WOW! Weather? Solar? Earthquake? What?!

Approximately 2:15pm CDT(I'm in Central Texas, about an hour & a half drive West/Northwest of Austin) I experienced the start of a SERIOUS, seriously LOUD & instantaneous ringing in my ears. It initially started(again, nearly instantaneously, no slight ringing building to a crescendo but quickly, as in the ringing was SO loud & happened SO quickly that it gave me goosebumps & wrenched my attention away from the movie I had been watching) in just my left ear but within seconds was off the charts in both ears.
It's nothing which can be attributed to the room I was in, I.E., something caused by the electronics, because I have since gone outside & it's continued, unabated, for nearly a half hour, thus far.
Has anyone else experienced a similar ringing, in a similar timeframe, over the last half hour or so? I am HIGHLY sensitive to magnetic & electrical changes(storms, both terrestrial & Solar in origin) & have memories of being effected(headaches, ringing in one or both ears) by earthquakes(I haven't lived in a seismicly active area since we moved to the Austin, Texas area, from the Seattle, Washington area, where I had spent nearly all of my life) but thought I would post this before I started looking into Solar & earthquake activity.

Thank you for taking the time to read this.
