The HearDefenders-DF™ Attenuation Study was conducted from 50 dBa to 110 dBa verifying how attenuation values increase as noise levels increase. When compared to average performances from solid ear protection, HearDefenders-DF™ clearly demonstrate the ability to hear critical acoustics (sounds) better while suppressing unwanted noise. The information above refers to attenuation provided when both filters are worn.

Note: The U.S. Environmental Protection agency requires manufacturers to provide a Noise Reduction Rating (NRR) on all hearing protection type products being marketed into most commercial type accounts. According to E.P.A. Document 08AR-2003-0024, exception to this requirement may be granted to entities participating in National Security. OSHA regulations state volume levels of 80-85 dB are safe for an eight hour period of time.
Please consult a hearing healthcare professional who can advise you about safety levels and appropriate filtering options.
The Chameleon Ears™ HearDefenders-DF® Earplugs is our custom-fit option for the HearDefenders-Df Product Line.
The Dual Filter of this custom-fit product provides variable attenuation – as the nose level increases so does the noise reduction. Until now military, law enforcement or even coaching staffs were never able to purchase a multi-functional dual filtered earplug that was designed to help you hear speech better in noise and be hooked up to two-way radio communications – now you can! When compared to average performances from solid earplugs, the Chameleon Ears™ HearDefenders-DF® Earplugs clearly demonstrates the ability to hear critical sounds better while suppressing unwanted noise.
Chameleon Ears™ are super soft hydrophobic silicone earplugs. While similar to our Insta-Mold earplugs, they have more durability and flexibility. These earplugs are our most customizable product and can be produced in a variety of brilliant solid colors that can be swirled together, glitter can be added or they can be made to glow in the dark.

This chart was conducted from 50dBa to 110dBa and verifies how the NRR values increase as the noise level increases. When compared to average performances from solid earplugs, the HearDefenders-DF® clearly demonstrates the ability to hear critical sounds better while suppressing unwanted noise. (Information provided is with both filters installed)
With this new breakthrough in being able to produce a non-electronic earplug with the aspects of increasing noise suppression to louder noise environments, we call this product HearDefenders-DF® and have made it available in a choice of different colors, 3 easy-to-insert sizes and a removable cord.
