Product Description: Noise Reduction Rating NRR 30Soft foam tapered toward the top for a soft, comfortable fitTapered design for a comfortable fitNot made with natural rubber latexNoise Reduction Rating: 30 decibels (when used as directed). Conventional hearing protection has a noise reduction rating ranging from approximately 0 to 30 (higher numbers indicate greater effectiveness). Information required by the EPA: The noise level delivered to the human ear when wearing a hearing aid according to the guidelines is approximately approximated by the difference between the A-weighted environmental noise level and the NRR. Example: The environmental noise level measured at the ear is 92 dBA. The NRR is 30 decibels (decibels). The noise level delivered to the ear is approximately equal to [92 decibels (A) - 30]62 decibels (A).
How to Use: With clean hands, slowly insert the plug into the wrinkle-free cylinder. While pressing the plug, insert it into the ear canal. When inserting, pull the outer ear outward and upward to make it easier to wear. Use your fingertips to hold the plug in place until it begins to expand.
Caution: For noisy environments where frequencies below 500 Hz are predominant, the C-weighted environmental noise level should be used. Improper attachment of the device will reduce the noise reduction effect. Refer to the enclosed product manual for proper 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 out non-continuous noises such as gunshots. Do not cut the earplugs. Close adult supervision is required when used by children. Inspect the plug before use and replace it if it shows any signs of damage or use. Do not use for long periods of time. This product is for single use only. Infants and children should not put the earplugs in a windpipe, which may cause suffocation. If you experience pain or discomfort when taking this product, stop taking it.
