I have had this shield for about 8 months, and, like you, I bought it in hopes of reducing wind noise. Although the shield is significantly better than the stock shield, it did NOT reduce the wind noise. I live in Las Vegas and I like the shield because it does allow for some air flow around the torso which helps keep me cool. Also, it moves the air flow over my helmet so no more bugs splatter my face shield. For noise, I wear ear plugs. If I had to do it over again, I would probably buy a different shield.
