  • Noise Reduction Rating
    Select by Noise Reduction Rating

    The NRR is a single number method that describes the overall sound level reduction across frequencies (attenuation) of a HPD in decibels (dB) based on a laboratory test. Since the NRR is a laboratory test it is recognized that it may overestimate the protection achieved by users in their workplace settings. Therefore, it is recommended that the NRR be de-rated in order to better estimate workplace protection. Use product filters below to select products available by decibel need.
