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.
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
Ear plugs must be inserted properly for optimum performance. With clean hands, firmly roll entire ear plug between thumb and fingers to form a thin tight cylinder. Using one hand, gently lift top of ear up to open ear canal. With other hand, insert rounded end of ear plug. 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 audio and video instructions at HEAROS.com. discard product after several uses or as soon as dirt or wax accumulates on ear plugs.

High Protection - NRR 32
The Future is Hear
WarningsKeep out of reach of children. As with all dietary supplements, consult your healthcare professional before use. See product label for more information. Keep away from infants. This product is non-toxic but may interfere with breathing if caught in windpipe. Caution 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.
