Not Tony Soprano here - call me 1Bluejay Soprano (true on both counts). Here’s what I read about “shotgun ear” - deafinitely related to shooting firearms.
I found it interesting to read that the ear closest to the shotgun is actually protected a bit, so it’s typically the OTHER ear that’s affected. That said, I gave up shotgun shooting after a few years cuz even with fitted earplugs AND a headset over that, I was afraid of losing even MORE hearing from the little margin I have left. Indoor shooting range for pistols was even SCARIER. I don’t think my shooting left me with shotgun ear, cuz both ears are abysmally bad and ring with tinnitus 24x7 ever since my teen years.
If hearing aids were to help, it seems that one would need the affected ear programmed with different settings that would be copied over into the Music, Speech in Loud Noise, Comfort, or any other program. I wonder if that can be done?
