Hi, Without reading this entire thread (sorry if this has been said to death already), reading your opening post I was instantly thinking about ear plugs. Which I do swear by these days. BUT one other thing that attributes significantly to wind noise is helmet FIT. Or rather, lack of fit. You can talk about noise coming from any aspect of motorcycling, I mean yes- it's a noisy sport. But the best starting point is to get decent or custom made ear plugs (even cheap foam ones are better than none at all) AND get a helmet that fits your head. The two key ways to decrease noise. THEN analyze everything else.
