PRO TIP
NOISE REDUCTION RATINGS
The Noise Reduction Rating (NRR) refers to a laboratory-derived numerical estimate of the noise reduction that a hearing protector offers. In most cases, this number overstates the protection actually afforded to workers due to fit, wear, and other issues. To ensure workers are not exposed to dangerous noise levels, employers need to apply a “safety factor,” which is typically a 7 dB subtraction. For example, if the hearing protector has an NRR of 25 and the employee is exposed at 100 dBA, then the protector attenuates the employee’s exposure to a value of 82 decibels: 100 - (25-7) = 82. Note: OSHA recommends employers apply an additional 50 percent safety factor, by cutting the NRR in half prior to subtracting 7 dB.
