The legend:
f = test frequency

Mf = mean attenuation value

sf = standard deviation

APVf = Assumed protection value

H = high frequency attenuation value (assumed noise level reduction with LC – LA = -2 dB)

M = mean frequency attenuation value (assumed noise reduction with LC – LA = +2 dB)

L = low frequency attenuation value (assumed noise level reduction with LC – LA = +10 dB)

SNR = single reduction index (the value subtracted from the weighted sound pressure level C, LC, to calculate the effective A-weighted sound pressure level in the ear canal)
