I have had tinnitus in both ears, 24/7/365, now for 25+ years. Never stops or reduces. For the most part I have always worn full face helmets and ridden behind a fairing/windshield, for at least 30 years of my 42+ years of riding. However, the turbelent air of a fairing/windshield can create a lot of noise.
But for me, it seems if I wear earplugs, after the ride the tinnitus is actually louder, to me. Also, when I wear earplugs and walking around, each step sounds like a drumbeat in my head. So, most often, I don't wear earplugs.
When life throws you a curve,.....lean into it!
