I think you answered your own question
Dear Motor7, tinnitus is the cumulative result of
Continued noise exposure from day one. Mine is
related to a combination of vocational and recreational
noise exposure. Power tool are among the top offenders.
At first after reading Fred Rau's Touring Bible I thought

relatively quiet bike (K1200 LTC). Just traded for a R1200GS.

Not hearing is not safe either. The only bummer is being
plugged I Hear my tinnitus all ride long.
