I get an interesting windnoise when strong wind hits my windshield at a certain angle as near as I can figure (prevailing wind direction, high wind velocity, my speed, and my angle to the wind seem to factor into it). I stopped worrying about it, but I do notice it when it happens at higher speeds on certain days. I have also noticed I hear a lot more noises with certain helmets than others. I hear very little with the Bell Revolver modular I wear in cooler weather. The HJC open face with a shield installed and the neck padding removed I use in Summer, I hear a lot more.
