Noise Reduction Rate (NRR): 29 dB.
Test compatible with 3M™ E-A-Rfit™ Validation System. Research suggests users will receive less noise reduction than indicated by NRR due to variation in earplug fit, fitting skill, and user motivation. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection.
