These earplugs are commonly used in the following industries: agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas and pharmaceuticals. These earplugs have a noise reduction rating (NRR) of 28 dB, CSA class AL. However, research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit, earplug fitting skill and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection. These soft polyurethane foam earplugs are test compatible with the 3M™ E-A-Rfit™ validation System.
