Thule roof bars noise.

This breaks up the vorticies that create the whistling noise in the first place and is easier than repositioning your rack. The design keeps vortices from slapping back together after the antenna has sliced through them. They are noisy and when it rains they whistle especially when bike carriers are attached. The new aero foil cross bars provides a significant improvement in roof rack noise.

The thule aeroblade and rhino rack vortex bars both feature noise reducing strips that makes them almost silent in many applications. All roof bars will make some noise.
