You've sparked my interest. I didn't know this about the ringing in one's ear.

I had only heard of seraphim from my Christian day school so I looked it up. "Seraph" or plural seraphim means: "an angelic being, regarded in traditional Christian angelology as belonging to the highest order of the nine fold celestial hierarchy, associated with light, ardor, and purity." Wow - and I'm down the rabbit hole. Thanks to you! :)
