A friend of mine used to listen to loud music then starting about 15 years ago he started turning the music down because it bothered him.
With his job he’s around loud noise every day.
He works building and rebuilding drilling rigs, mainly offshore rigs. Steel on steel banging around him for hours.
Because of the noise he has to wear earplugs. When he takes the earplugs out everything is loud to him.
Even with earplugs he’s lost some hearing in certain sound ranges but at the same time he can hear or possibly just pays attention to sounds he never heard or paid attention to before.
That’s almost exactly the same with me.
I’ve wondered if all people can actually hear the sound but the brain just doesn’t process the sound until you loose some hearing then the brain starts processing the sound to compensate for the loss.
