Protechs, Work Earplugs, 8 Pairs, Case Included

Product Description: Noise Reduction Rating - 33 Decibels Foam Earplugs Highest NRR tested by an independent agency Diagonal design with tapered ends for a soft, comfortable seal. Information required by the EPA: When wearing a hearing aid according to the guidelines, the noise level transmitted to the human ear is approximately approximated by the difference between the A-weighted environmental noise level and the NRR. For example: (1) The environmental noise level measured at the ear is 92 dBA. (2) The NRR is 33 decibels (decibels). (3) The level of noise entering the ear is approximately [92 decibels (A) - 33]59 decibels. The noise reduction rating of conventional hearing protectors ranges from approximately 0 to 30 (the higher the number, the more effective it is). Noise Reduction Rating: 33 decibels (when used as directed)

How to Use: With clean hands, slowly insert the plug into the wrinkle-free cylinder. Insert the plug into the ear canal while pressing it. When inserting, pull the outer ear upwards and outwards to make it easier to wear. Use your fingertips to hold the plug in place until it begins to expand and block out noise. The degree of noise reduction will vary depending on the proper insertion method.

Caution: Do not cut the earplug. Inspect the plug before use and replace it if it is damaged or shows signs of use. Do not use for long periods of time. This product is for single use only. Keep the earplug out of reach of infants and children, as they may get caught in the windpipe and suffocate. Stop using this product if you feel pain or discomfort. For noise environments where vibrations are mainly below 500 Hz, the C weighted environmental noise level should be used. Improperly wearing the device will reduce the noise reduction effect. Refer to the enclosed product manual for proper attachment. Although earplugs are recommended to prevent damage from excessive noise, the noise reduction ratio (NRR) is based on continuous noise reduction and cannot completely block out discontinuous noises such as gunshots. Prolonged exposure to noise levels above 85 decibels can cause gradual hearing loss.
