“our stupidity for loosing our hearing in the first place.”
Not always our stupidity. First 8 years of my time in USAF they put me behind a CRT which was radiating into my brain and told me to write on the glass with a grease pencil. Almost everyone in tactical radar controller career field lost most of their hearing and has a ringing in their ears.
Try setting 3” away from 120mm cannon fire in a vehicle powered by a screaming turbine engine.
