Acoustic transparency is critical for situational awareness when cycling. While some products incorporate materials that block or deflect sound transmission - including desired sounds, we focus on optimizing the signal to wind noise ratio. Clear communications, and pinpointing the location of sound sources, are important. Our products are tested for acoustic transparency / sound source localization.
Various wind protection products have different acoustic properties, with differing acoustic transparencies. The acoustic transparency of any wind noise reduction product will have a greater or lesser effect on the audio, depending on the material and design. A less porous material will show an attenuation of sound at higher frequencies. A more porous and less dense material will have a lesser effect on high frequencies (therefore more transparent).
Our proprietary materials permit the free passage of sound energy without frequency interference.
"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."
