Product Description: Ultimate Softness Series™NRR 32Tested by ANSI Specs S3.19-1974The level of noise heard by each person when wearing earplugs is closely measured by the difference between the A-weighted environmental noise level and the NRR. Noise reduction ratio: 32 decibels (when properly worn)The noise reduction ratio ranges from approximately 0 to 30 (with significantly greater effectiveness).
How to use: For best results, the earplugs must be inserted properly. Using clean hands, gently compress the earplug between your thumb and index finger and twist until it fits snugly. Gently lift the top of your ear with one hand to open the ear canal. With the other hand, insert the rounded end of the earplug into your ear. Hold the earplug with your index finger until it expands to a comfortable, snug size. It is recommended that you practice insertion. If you use the earplugs multiple times or if they become dirty or waxy, discard them immediately.
Caution: Keep out of reach of children. This product is non-toxic, but may block the bronchial tubes and cause breathing difficulties. In environments with noise exposure below 500 Hz, the C-weighted environmental noise level should be used. Improper wearing of the device will reduce the noise reduction effect. Please refer to the description above to wear it properly. 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 discontinuous noises such as gunshots. The noise reduction rating (NRR) calculated from the attenuation data is 32 decibels. Proper wearing of the earplugs is necessary for effective noise reduction. Refer to the description.
