Interestingly enough, I had really started digging into this in the last few weeks. It seems like I read somewhere that the wind buffeting can reach the neighborhood of 110db. That's really loud. Think about it, if you are listening to music at a fairly high level, the wind noise can still drown it out to where it's inaudible.

I have a couple 35mhp+ stretches that I hit every day that started me pondering this issue. Motorcyclists also encounter hearing loss if they aren't wearing full coverage helmets.

I did uncover these http://www.slipstreamz.com/ , and have briefly tried them out. They do seem to cut the noise down significantly even with me not installing them correctly. The only place i could find that was selling them was here: http://www.macfriends.com/index.asp?...OD&ProdID=2479

I'm currently working on a different design that is more of an airfoil to lift the air over the ear, while leaving the ear uncovered. We'll see how that pans out.

In the interim , I would say check out the slipstreamz.... if for nothing more than additional geek factor that they provide. Cuz these are the geekiest things I have ever seen. Yes, they far surpass even the orange safety vests.
