Description
6 pair. Hearos ®. Ear plugs. Ultimate Softness Series™. High protection. NRR 32.Other Description
Tested according to ANSI specs S3.19-1974. The level of noise entering a person's ear, when hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Attenuation Chart: Frequency 125 - Mean Attenuation (dB) 38.4 - Standard Deviation (dB) 2.9. Frequency 250 - Mean Attenuation (dB) 40.3 - Standard Deviation (dB) 3.5. Frequency 500 - Mean Attenuation (dB) 43.2 - Standard Deviation (dB) 4.0. Frequency 1000 - Mean Attenuation (dB) 41.8 - Standard Deviation (dB) 3.8. Frequency 2000 - Mean Attenuation (dB) 38.6 - Standard Deviation (dB) 2.6. Frequency 3150 - Mean Attenuation (dB) 45.0 - Standard Deviation (dB) 2.8. Frequency 4000 - Mean Attenuation (dB) 45.7 - Standard Deviation (dB) 3.5. Frequency 6300 - Mean Attenuation (dB) 49.6 - Standard Deviation (dB) 3.8. Frequency 8000 - Mean Attenuation (dB) 47.3 - Standard Deviation (dB) 4.3. Example: 1. The environmental noise level as measured at the ear is 92 decibels dB(A). 2. The NRR is 32 decibels (dB). 3. The level of the noise entering the ear is approximately 60 dB(A). Noise Reduction Rating. 32 decibels (when used as directed). The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness). Federal law prohibits removal of this label prior to purchase. EPA. Label required by U.S. E.P.A. regulation 40 CFR part 211, Subpart B. Hearos is a registered trademark of Bumble BE Holdings, LLC.

Caution: keep away from infants. This product is non-toxic but may interfere with breathing if caught in windpipe.For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the above instructions for proper fit. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, The Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire. The Noise Reduction Rating (NRR) calculated from the attenuation data is 32dB. Ear plugs must be properly fitted to attenuate noise effectively. Refer to instructions.
