Flents Flents, Protechs, Ear Plugs, Travel, 1 Pair with Case

Description Noise Reduction Rating 24 Decibels Allows You to Turn Protection Off When Needed EPA Noise Reduction Rating: 24 Decibels closed, 4 Decibels open (when used as directed). The range of noise reduction ratings for existing Hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness) PROTECHS™ Flip to Listen® Ear Plugs have a dual mode, allowing with a flip to easily switch from a closed to open position without the inconvenience of removing. These ear plugs are durable, reusable and can remain comfortably in place for hours. Information required by EPA: The level of noise entering a person's ear, when a hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Example closed: (1) The environmental noise level as measured at the ear is 92 dBA. (2) The NRR is 24 decibels (dB). (3) The level of noise entering the ear is approximately equal to [92 dB(A) - 24] 68 db(A). Example open: (1) The environmental noise level as measured at the ear is 92 dBA. (2) The NRR is 4 decibels (dB). (3) The level of noise entering the ear is approximately equal to [92dB(A) - 4] 88 db(A). The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness). Expiration Date 01/01/2028 00:00:00 UPC 025715680545 Suggested Use Reach over the head and pull top of ear upward. With other hand grasp plug and gently push and rock into ear canal until a good fit is made. For air travel, insert before take off and remove after landing. Warnings Remove with a slow twisting motion to break the seal. Do not cut earplugs. Inspect product before use and replace plugs if they are damaged or show signs of wear. Not for prolonged use. Product intended for single user only. If you should experience pain or discomfort when using this product, please discontinue use. Keep ear plugs away from infants and children as they may get caught in windpipe and create a choking hazard. 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 enclosed 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.
