Good Morning, Mike, and All,
Thanks, everyone, for your comments and suggestions. Mike, after the holidays, I'll go in for a test and see if anything is out of the ordinary, or worse than normal. Good suggestion. I do know that, many years ago, my wife and I were snow-camping at around 9,500 feet, and had setup our tent camp on top of 12 feet of snow, in a lovely meadow on Mount San Jacinto. Sometime during the night, I woke up, and thought a freight train was getting ready to come right through our tent!!
I fought my way out of my sleeping bag, and ripped open the zipper in our tent door, to see what horrible thing was getting ready to do us in!! Guess what? It was only my ears ringing!!
Up that high, in the wilderness, camped on snow, which is a great absorber of sound, the quiet was SO absolute, that it seemed my normal ear ringing was magnified about 100 fold!!
My wife told me that her ears, too, seemed to ring louder than at home, which was interesting.
In any case, I'll keep an eye on it, or, better said, "an ear", and get a check-up after the New Year. We must take care of our ears, as where would we be without the ability to enjoy our music??? Take care, and God Bless!
Every Good Wish,
Mark (Ye Olde Doc)
