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.
