Our Favorite Cycling Wind Gear 

"With Cat-Ears / AirStreamz, I found I was enjoying rides more... Simply because I could hear more of what I wanted and less of what I didn't."

G. Liu / J. Lindsay, Bicycling Magazine

Triathlon Essentials for Racing Fast, Training Hard, and Having Fun

"Wrap this half inch pile material around your helmet strap to reduce wind noise in your ears...  so you can more easily hear cars coming and friends talking."

Erin Beresini, Outside Magazine 

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

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.

 

Aeroacoustics

The theory of aero-acoustics, the physics describing the generation of sound by unsteady airflow, is difficult and not complete.  The location of the sources of wind sound via measurement is challenging and requires specialized test facilities and equipment.  Understanding the theory is important for effective product design.

Testing / Analysis

In addition to road testing, we perform extensive analysis in our custom wind tunnel and hydrodynamic flume.  We utilize precision audio equipment, spectral analysis software, hot-wire anemometers, pressure transducers, and air-flow visualization.  Furthermore, our products have been tested at Brandenburg Technical University.

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 (#9078482B2 - 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 don't 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.

Custom Windscreens

Highly respected companies and organizations have selected our custom windscreens.  The unique properties of our pile materials contribute to unsurpassed performance.  And they are very effective in extreme wind conditions.
