High-quality earplugs that do not cause discomfort while significantly reducing the noise level.

The noise level entering the ear of a person wearing earplugs (when used as intended) is close to the difference between the intensity of the actual sound produced and the NRR value of the earplugs.

Example:

• The ambient noise produced measured at the ear is 92dBA.
• The NRR of the earplugs is 23 decibels (dB).
• The noise level entering the ear is approximately equal to 69 dBA.
