Understanding Wind Noise

Wind noise is a complex phenomenon spanning aerodynamics, acoustics, and the physiology of human hearing.  The amount of noise generated depends on factors like 1) speed, 2) riding position, 3) turbulence, and so on.  At moderate cycling speeds, wind noise can impact the ability to hear surrounding sounds.

 

Understanding the complexities of Ear-Wind noise requires specialized testing / analysis.
