Hearos Water Protection Series Ear Plugs, Super Soft, for Adults and Kids, Bonus

Trusted since 1992. 2 pair + 1 pair free + free case! Hearos.com. 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. Example: 1. The environmental noise level as measured at the ear is 92 decibels db(A). 2. The NRR is 27 decibels (dB). 3. The level of the noise entering the ear is approximately 65 dB(A). Attenuation Chart (ANSI S3.19-1974): 125 Frequency: 34.4 (dB) mean attenuation, 5.6 (dB) standard deviation; 250 Frequency: 35.5 (dB) mean attenuation, 5.4 (dB) standard deviation; 500 Frequency: 37.4 (dB) mean attenuation, 5.1 (dB) standard deviation; 1000 Frequency: 34.4 (dB) mean attenuation, 4.1 (dB) standard deviation; 2000 Frequency: 37.8 (dB) mean attenuation, 4.0 (dB) standard deviation; 3150 Frequency: 40.7 (dB) mean attenuation, 4.6 (dB) standard deviation; 4000 Frequency: 40.9 (dB) mean attenuation, 3.8 (dB) standard deviation; 6300 Frequency: 43.1 (dB) mean attenuation, 3.7 (dB) standard deviation; 8000 Frequency: 45.4 (dB) mean attenuation, 2.6 (dB) standard deviation. Noise Reduction Rating: 27 decibels (when used as directed). The range of noise reduction rating for existing hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness). No. 3101. Federal law prohibits removal of this label prior to purchase. EPA. Label required by US EPA regulation 40 CFR Part 211, subpart B. American made. Made in USA.
