Cat-Ears are proven to be probably the greatest Wind Noise* reduction products of their kind (see chart).
They have been independently tested, reviewed, and recommended by Bicycling and Outside Magazines.
The mid-sized AirStreamz, based on PileTech materials engineering, are recommended for Casual to Club Club Cyclists.
Aero-acoustically developed, AirStreamz are made from soft pile materials that interact with oncoming wind (dampen / dissipate / deflect) – reducing the intensity of noise producing wind turbulence.
Cat-Ears products are sound permeable for protected road cycling. “Wind Noise can inhibit one’s ability to distinguish traffic noise. Cat-Ears don’t restrict hearing whilst others I’ve tried do.” – Adventure Cycling Association.
*Wind Noise is a complex phenomenon spanning aerodynamics, acoustics, and the physiology of human hearing. The amount experienced depends on factors like: 1) speed, 2) riding position, 3) head shape, 4) turbulence, and so on. With Cat-Ears, wind noise levels are reduced by 14-16 dBA between 20 and 20k Hz. This can be a reduction in sound pressure level of ~75%. But microphones and ears behave another way. And whilst the amount of perceived wind noise reduction averages ~60%, we stand in the back of our products as probably the greatest devices of their kind on the market. Material effectiveness has also been tested at Antioch University.
“Cat-Ears work dramatically well. I found I used to be enjoying rides more, simply because I could hear more of what I wanted to, and less of what I didn’t.” – Bicycling
Designed with air ‘drift through’ porosity, Airstreamz wick away perspiration.
