Calculation of the intrinsic error in hearing protector ratings.
NHCA Spectrum 2004 Feb; 21(Suppl 1):27
The secondary label of the Noise Reduction Rating (NRR) is required to disclose the mean attenuation and standard deviations for the real ear attenuation at threshold (REAT) measurements. However, the overall error of the NRR has been largely ignored. Using covariant statistics, Monte Carlo simulation and Bootstrap simulation methods, the error in the noise reduction rating has been estimated and applied to several experimental studies.
