Ok I have to share this Eddy story.
I PM'd him a while back about the THH helmets and wind noise. At that point he didn't have any in stock. I happened to remeber it this morning and asked him again. Well about an hour after I get this;
OK here is the most up to date research...I just went out and did it.
The THH half helmet "beanie" T-69 behind a windscreen is actually quieted than riding with no helmet at all as the downward straps have a covering over that protects the ears.
Without a windscreen in the open air, there was a notable difference between without a helmet and no helmet. Still plenty noisy either way without a screen with wind in the face. Same is conversely true with full helmet in open wind, still lots of noise...normal.
