Hearing Protection NRR
Hearing protection NRR labels potential attenuation on packaging—real-world reduction depends heavily on fit; distance still matters.
Hearing protection NRR is the Noise Reduction Rating on packaging—higher numbers mean more potential attenuation if fit is perfect, which real ears rarely achieve. Derate foam and plugs in practice; combine with distance from speakers.
NRR guides shopping; fit verification guides safety.
