I wonder how any of our hearing is holding up. Depending on what side of the stage I was on I would always stuff a hearing protector in the ear closest to the drums, no matter how big the stage was. Those hats in my right ear or the ride cymbal in my left was deafening. All in all I'd say my overall hearing is almost perfect by taking precautions like this.
My left ear had a premature roll off of my bass frequencies... Blamed on driving with a car window down.
Up until one audition of a gorilla for a drummer, I had as perfect hearing as their machines could detect (minus the bass loss) well into my mid-40s. I had a few times where I heard the test being given to another person... The systems weren't isolated enough. Tinnitus is a bitch.
My eyesight used to be great too... Never given an official "20/10," I did read copyright information from the bottom of the chart a few times too.
