On the tinnitus, I suggest a health care provider's analysis. It was helpful for me to know what's up, what I don't hear, and have a doctor say my family should be respectful and not be important or angry over something I can't fix. Unfortunately there was no fix for the actual problem. They said what I have going on is typical of someone my age who had industrial jobs at an earlier time. I'm convinced those loud old Macks and Detroit Diesel engines in old poorly insulated trucks did more damage than turbos. Old Mack B series with the non-turbo 673 and 711 were loud. A Cummins engine vs Detroit was always easier on my brain. This was part of my teenage sound track. Later on Kenworths or Volvos with Cummins were much easier on the brain.
