NRR is the Noise Reduction Rating in decibels (dB). It is the average noise reduction obtained by a group of people wearing a specific hearing protector in a laboratory test. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit and and wearing time. It is recommended that the NRR be reduced by 50% for estimating the average amount of noise reduction provided.
