I use earplugs on trips >30 minutes or so, and find they reduce fatigue a lot (not to mention save your hearing when you become a geezer like me). You might want to try different types of earplugs as the dB rating varies. My favorites are silicone earmolds that I got at the SBK races at Laguna last year. They cut out a lot of noise, but I can still hear the bike and traffic (much attenuated).For some strange reason I tried riding with earplugs about a week or so ago. I do not know why, but all of a sudden I got this paranoid idea that the noise of traffic is making me go deaf and I should wear ear plugs. Anyway, I tried riding with earplugs and my conclusion Never again!!!!
