My tinnitus started with an MRI with plugs and ear muffs. That doesn't happen to most people. Then it got worse a few year later from an immersive music event. Many people in the room, classical not rock, and I assume most people didn't get tinnitus. It is possible that some of us have auditory nerves/cranial nerves that are more vulnerable or even that some accumulation of sensitivity from work reached a tipping point. People tell me they get tinnitus after a rock concert and it goes away. I wonder if you can take a vacation and see if yours goes away!! Look up Tinnitus Talk and also the Hyperacusis forum. They are helpful but avoid the negative posts! An ENT or audiologist who is expert in this area is a good resource as always since we are just fellow patients.
