Correct. The reason is that your brain doesn't have to waste cycles weeding through high-frequency white noise brought on by the wind. In fact, most professional musicians playing in loud venues either wear foamies or invest in custom-fit, musical-grade attenuators, not only to save their hearing, but also to better discern musical detail. I know, that sounds contradictory - wearing noise attenuators to better hear the music - but it's how the brain works. See here for a little more about why musicians do it. When I was young, I played a lot of gigs with powerful amps and attended a bunch with even bigger rigs. I didn't notice it at the time, but it definitely damaged my hearing. I now experience a distinct ring from the tinnitus all the damned time and there is no surgical or pharmaceutical solution for it. Had I bought good quality earplugs when I was young, I'd have much better hearing today. The good thing is that I wised up and am taking action to prevent it from accumulating even more. So, I wear earplugs every time I ride for more than 30 minutes and I love it. Less fatigue, I can still hear middle and lower frequencies just fine, I can hear my friends on the intercom, pedestrians, car horns and everything else, just without the massive din of wind noise. The law against earplugs was never written for motorcycles and is out of sync with what's good for us and everyone around us. Sure, most enclosed cars don't need any more attenuation, but bikes and open-top cars are a different matter. If we're going to let motorcyclists NOT wear a helmet, we should at least let them protect their hearing and distinguish middle and lower frequencies better.
