The RX stores sell a product called ear health. It improves blood flow to the inner ear and can help. I have Tinnitus pretty bad sometimes and a little all the time.
Its permanent damage and is mostly from the wind noise. At high speed the db levels exceed a rock concert first row. Some of the louder pipes are downright dangerous. They cause temporary deafness. Ever walk out of a live band bar and can barely hear for a while. That is your body shutting down hearing for protection from the sound. Little bits of damage every time you do it.
Oldroadie probably knows a ton about this stuff.
I predict the tinnitus for this poster has always been there but the temporary desensitized hearing makes it more apparent.
