Nanos Extra Small Ear Plugs - 25 Pair
Ear Plugs, Extra Small
Nrr 28. Tested according to ANSI specs S3.19-1974. The level of noise entering a persons ear, when hearing protector is worm as directed is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Attenuation chart (ANSI S3.19-1974): 125 frequency: 34.1 mean attenuation (dB); 4.3 standard deviation (dB). 250 frequency: 31.8 mean attenuation (dB); 3.7 standard deviation (dB). 500 frequency: 35.1 mean attenuation (dB); 2.9 standard deviation (dB). 1000 frequency: 34.8 mean attenuation (dB); 3.7 standard deviation (dB). 2000 frequency: 36.3 mean attenuation (dB); 0.5 standard deviation (dB). 3150 frequency: 39.6 mean attenuation (dB); 3.2 standard deviation (dB). 4000 frequency: 45.0 mean attenuation (dB); 4.4 standard deviation (dB). 6300 frequency: 41.3 mean attenuation (dB); 4.2 standard deviation (dB). 8000 frequency: 46.9 mean attenuation (dB); 4.2 standard deviation (dB). Example: 1. The environmental noise level as measured at the ear is
Warning Contains: 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 attenuate 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 28 db. Ear plugs must be properly fitted to attenuate noise effectively. Refer to instructions.
Directions Easy Instructions: Ear plugs must be inserted properly for optimum performance. 1. With clean hands, firmly roll entire ear plug between thumb and fingers to form a thin tight cylinder 2. Using one hand, gently lift top of ear up to open ear canal. With other hand, insert rounded end of ear plug. 3. With forefinger, hold ear plug in place until it expands to form a comfortable, snug fit. Practice of insertion is recommended. Please refer to the fitting video instructions at hearos.com discard product after several uses or as soon as dirt or wax accumulates on ear plugs.
