"The average person facing a 21 mph wind experiences wind noise at an intensity of 92 dB."

(Experiments on the Noise Heard by Human Beings when Exposed to Atmospheric Winds, NTNU, Trondheim, Norway)

"We use our hearing as an early warning system, and hearing swiftly redirects our vision.  This shift in gaze is critical to our capacity to assess the location, direction of travel, and velocity of approaching vehicles.  In addition, visual perception is more accurate and faster when the visual stimulus is paired with an auditory one."

Hear the Wind Noise Difference - How Cat-Ears / AirStreamz work at 15 miles per hour.  

  • Wind Noise at 15 mph - without Cat-Ears / AirStreamz

  • Wind Noise at 15 mph - with patented Cat-Ears / AirStreamz


We test our products at different speeds (10-35 mph), turbulence levels, and yaw / pitch variations.

Wind Noise

Wind noise is a complex phenomenon spanning aerodynamics, acoustics, and the physiology of human hearing.  The amount of wind noise experienced 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.

Testing / Analysis

In addition to road testing, we perform analysis in our custom aero-acoustic wind tunnel.  We utilize precision audio equipment, spectral analysis software, hot-wire anemometers, pressure probes, and flow visualization.  Our products have also been tested at Universität Siegen and Brandenburgische Technische Universität.

Materials Engineering

Characteristics like porosity, permeability, and diffusion are evaluated for wind noise reduction effectiveness across a range of wind speeds and turbulence levels.  In this regard, we are the only cycling associated company to hold a wind noise reduction utility patent (No. 9,078,482 - Sound Permeable Wind Noise Reduction Device).

Acoustic Transparency

Communications and the ability to determine the location of surrounding sounds, like approaching vehicles, can be important for safer cycling.  Our products do not block the sounds that you want and need to hear.  In this regard, the materials we use have been independently tested for transparency at Antioch University.
