• Description:
  Present ANSI and ISO standards suggest calculating the mean real-ear-attenuation at threshold (REAT) and the standard deviations as well. These are used for calculating assume protection values (APVs) that are incorporated in calculations of the NRR in the United States and the SNR and HML in Europe and elsewhere. One of the discoveries from intense analysis of both experiment-fit and subject-fit REAT values is that they are not always unimodally and normally distributed around a mean or median, thus weakening the statistical relevance of the mean and standard deviation of the REATs. Methods for determining APVs that take into account the distribution of REATs and yet allow the computations to be otherwise unaffected will be presented. Additionally, suggestions for ratings other than the NRR, SNR, and HML will be made. [Description provided by NIOSH]
