Pro-Techs, Sea-Rite, Silicone Earplugs, Green, 6 Pairs, Case

Product Description: Noise Reduction Rating NRR21 Seals the entrance to the ear canal to conform to the ear Fits small ear canals of children Sea-Rite® Silicone Earplugs help keep water out when worn properly. Great for swimming. Noise reduction ratings for conventional hearing protectors range from approximately 0 to 30 (higher numbers indicate greater effectiveness). Noise Reduction Rating: 21 decibels (when used as directed) Information required by EPA: The noise level delivered to the human ear when a hearing aid is worn as directed is approximately approximated by the difference between the A-weighted environmental noise level and the NRR. Examples: (1) The environmental noise level measured at the ear is 92 dBA. (2) NRR is 21 decibels (dB). (3) The level of noise transmitted to the ear is approximately [92 decibels [A] ~ 21]71 decibels (A).

How to use the product: Roll the plug between your fingers with clean hands to make it smooth. Use the plug completely. Shape it into a ball. Flatten the plug against the ear hole. Close only the ear hole. Do not force it into the ear.

Caution: Seal only the outer ear. Do not insert into the outer ear canal. For noise environments where the frequency is less than 500 Hz, the C-weighted environmental noise level should be used. If the device is worn incorrectly, the noise reduction effect will be reduced. Please refer to the enclosed product manual for correct attachment. Although the use of earplugs is recommended to prevent damage from excessive noise, the noise reduction ratio (NRR) is based on continuous noise reduction and cannot completely block discontinuous noises such as gunshots. Check the plug before use and if the plug is damaged or shows signs of use, Replace. Do not use for long periods of time. For single-user use only. Do not cut, stretch, or disassemble the earplug. If not used as directed, the earplug may become lodged in the ear canal and require surgical removal by a qualified professional. If the earplug becomes lodged in the ear canal, do not remove it with tweezers or other tools. If properly removed, seek medical attention. It is okay if delivery is delayed by several days. The device may be less effective if placed incorrectly. Choking Hazard - This product is not a toy. Contains small parts. Keep out of reach of children.
