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
BikeRadar's First Look (2012) and Update
"Cat-Ears work well at reducing wind noise, particularly at higher speeds. Allowing improved awareness of surrounding traffic and racers. I heard little more than tires, gears, and birds on my a.m. ride."
J. Huang, BikeRadar / CyclingTips
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."

"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 speed of approaching vehicles. In addition, visual perception is more accurate and faster when the visual stimulus is paired with an auditory one."

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 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.
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.
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.

"Do they work? Yes, as advertised, We found it easier to hear traffic and carry on conversations."
J. Sumner, RoadBikeReview.com / MTBR
Adventure Cycling Association
"I can't say enough good things about this product. Wind noise can inhibit one's ability to distinguish traffic noise, often a first line of defense, particularly in an urban setting, Cat-Ears don't restrict hearing while others I've tried do."
P. Finley, Adventure Cycling Association
League of American Bicyclists Instructor / Coach
"I had the opportunity to try your products this weekend... About halfway through the ride, I suddenly realized that I could hear EVERYTHING that was being said in my group of 5 riders! I could still hear some wind noise, but I was very impressed with the fact that I could hear riders several bike lengths in front of me."
