ear care

I work in a loud enviroment, about 85 to 90 db. I wear foam ear plugs 29 nrr and ear muffs 30 nrr. I work a 12 hour shift but no more than 3 days in a row. I also wear hearing protection when mowing the yard, snow blower, and motorcycling.I'm 56 years old. Will probably work up to 65. My right ear is fine. The left ear rings which is probably why it does not test as well as the right ear. It has had this ring since I was about 19.I only listen to music about 4 hours a week. Peak spl about 94 db. Most of the music is below that. Listen to classical, jazz, blues, blugrass, and a little bit of rock.Any audiophiles out there that work in similar conditions and care about there ears. I'm hoping to enjoy this hobby into my 70s if I live that long with decent hearing.
