I'm sorry to hear (no pun intended).
Hearing loss ain't no joke. It can't be fixed, it doesn't heal.
My father and his father suffered with hearing loss for much of their adult lives. Pop was in the Army as a young man, around aircraft a lot. Granddaddy was around noisy machinery as a younger man. In those days there was no OSHA. Little attention was paid to hearing protection.
Pop used to say he had a roaring sound in his ears much of the time, it kept him awake a lot. His doc said it had something to do with his hearing loss and nothing could be done about it.
Sadly, even today some people don't get the word. I go to the local sawmill to scrounge firewood; them Amish fellas are working all day in that loud environment with no hearing protection. I've seen folks running chainsaws, noisy mowers, using leaf blowers and trimmers with no hearing protection. They're gonna regret it in time to come.
It's pretty much mandated now as PPE, at least in the workplace. I started working in factories in '84, my boss at the time was in his early 40s and wore hearing aids in both ears. The cause? Years of noisy factory work with no hearing protection. I remember thinking that I did not want to end up like that.
When I was DJing, school dances were the loudest and I kept a pair of ear plugs in the gig bag. Didn't need 'em for most other shows. Wear them ear plugs, folks, please.
