Protechs, Quiet Treat, Foam Earplugs, 25 Pairs

Product Description: Easy insertion shape that fits the shape of the ear canal EPA Softer, more comfortable Noise reduction rating: 29 decibels (when used as directed) Conventional hearing protection has a noise reduction rating range of approximately 0 to 30 (higher numbers indicate greater effectiveness). Information required by 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. (1) The environmental noise level measured at the ear is 92 dBA. (2) The NRR is 29 decibels (decibels). (3) The level of noise transmitted to the ear is approximately [92 decibels (A) - 29]63 decibels (A).

How to use the product: 1. Slowly insert the plug into the wrinkle-free cylinder with clean hands. 2. While pressing the plug, insert the pointed end of the plug into the ear canal. When inserting, pull the outer ear outward and upward for easier insertion. 3. Use your fingertips to hold the plug in place until it starts to expand.

Note: For noisy environments with frequencies below 500Hz, the C-weighted environmental noise level should be used. Improperly worn devices 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.
