These earplugs have a Noise Reduction Rating (NRR) of 29 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
