Thanks for the great and helpful responses here guys. I must admit, I'm a little paranoid when it comes to this Tinnitus and riding now. The Tinnitus is bad about 70% of the time and not so bad the balance of the time. ALWAYS terrible at night and when I wake up. If I knew that riding, especially long distance, would worsen the condition, I'd probably hang up the riding boots. I want badly, to hop on the bike and ride it coast to coast without worsening symptoms of Tinnitus...I know there's no guarantee. But, with my Schubert C3 Pro(has the Sena 10U bluetooth), plugs and possibly a Wing, this would be the best mode of wind protection, I guess. However, there is no protection from bone conduction while cruising the highways cross country at 70 MPH. The question for me is, will the helmet, plugs and bike diminish the Db level enough to minimize further damage. Evidently, prolonged(I don't recall the exact amount of time) but exposure to 85 Db can cause irreversible damage(or further damage in my case). I guess what I should do is rent a Wing for a day and put some miles on it and see what exists after.
