Sound Localization has a High Survival Value...
 

Don't let Sound Masking Wind Noise interfere with Situational Awareness

"A study by the League of American Bicyclists finds that the most likely type of fatal bicycle crash is 'motorist overtaking bicycle' - i.e. being struck from behind - accounting for forty percent of cyclist fatalities.”

The car that will hit you is the one you don't see or hear

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

 > Hear and react to approaching cars / trucks up to fifty percent sooner

> Easier communications with other cyclists    > Protect ears from excessive wind / noise

Our experience measuring the sources and types of wind noise allows us to engineer products for the most

challenging of conditions. Tested and recommended by respected publications and professionals,

Cat-Ears are 100% Satisfaction Guaranteed and Made in the USA.

The Worlds Best Selling and Most Effective Wind Noise Reduction Products for Cyclists.

Over 50,000 satisfied customers in 50+ countries. Over 750 unsolicited testimonials.

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

Joe Lindsey, Bicycling Magazine

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

"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."

James Huang, Tech. Editor, BikeRadar / CyclingNews

"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 in an urban setting. Cat-Ears don't restrict hearing while others I've tried do."

Patrick Finley, Adventure Cycling Association

Wind Noise

Wind noise is a complex phenomenon spanning aerodynamics, acoustics, and the physiology of human hearing. Aero-acoustic noise is a difficult topic and its theory is still under development. While measuring the sources of wind noise is difficult, it is critical for designing effective wind noise reduction products.

 

Exhaustive Testing

Exhaustive testing ensures that our products are the most effective of their kind on the market.​​ In addition to 'stress testing' in 'designed use' environments, we incorporate custom laboratory testing / evaluation:

 

  • Two Open Jet Wind Tunnels with Variable Turbulence.

  • Hydrodynamic Flume with Fluorescein Dye Visualization.

Cycling products are tested at speeds up to 40 mph and Windscreens are tested at speeds up to 80 mph.

Materials Engineering

Materials engineering makes a big difference. Anyone can re-package 'off the shelf' foam and faux fur. We evaluate, incorporate, blend characteristics like density, denier, texture, porosity, length, etc. Challenging conditions require specifically designed materials / products and we hold utility patent #US 9078482.

 

Acoustic Transparency

Acoustic transparency is absolutely critical for microphones and situational awareness when cycling. While some products incorporate known sound blocking / deflecting materials, we focus on optimizing the sound to wind noise ratio. Clear communications, and pinpointing the location of sound sources, is important.

"It has been said that 'the purpose of the ears is to point the eyes.' While the ability of the auditory system to localize sound sources is just one component of our perceptual systems, it has high survival value, and living organisms have found many ways to extract directional information from sound."

We stand behind our products as the most effective devices of their kind on the market.
