I also have that same hearing combination; what are the "teenager repellant devices" you speak of? Manual-labor jobs, manual-shift cars, and cell-phone signal jammers would be the only ones I know of.

It's just the Boomer (born in 1950) in me that makes me suggest those; I retired from my job at 65.5 (though I wanted to work longer), since I was the only one willing to do the grunt-work needed sometimes, and my body just wouldn't cooperate. The kids (18-22 years old) that upper management sent me wouldn't/couldn't do the hard work, or were "late to work/late from lunch/always on their phone" when I needed them. I spent more time babysitting than getting things done. And we all know they don't shift manual transmissions. Hahaha.

I admit I never took much care of my hearing, from the '60's rock concerts, gun shooting, and drag racing pastimes I had, to my job(s) in industrial environments, where I just used hearing protection occasionally. I got my tinnitus at a George Strait concert in 2014, but wondered why then, and not when working on engines or in the drag race environment, years before. Inevitable, I'm sure.
