I have been using earplugs since I started riding two years ago. I have sensitive ears, which I think is good because for the most part I have good hearing. Anyway, I noticed after w few long rides my ears would ring. It's not that the bike is loud, it's the wind noise from the helmet. I think I'd be better off with a quieter helmet, but I spent $200 on it. How much does one have to spend to get a quiet helmet!? Don't answer that....I'm sure it's probably in the $700 range. Anyway, I never ride without hearing protection now. I consider it part of my ATGATT. And at over 100 decibels, wind noise is no joke. The old timers will tell you to wear them, if they could hear you ask if you should.
