The HearDefenders-DF™ Attenuation Study

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 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 EPA 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.
