1
F = Frequencies at which attenuation is measured.
2
Mf = Mean value.
3
Sf = Standard deviation.
4
APV (Mf-Sf) = Assumed Protection Value.
5
H = High frequency attenuation value (predicted noise level reduction for noise where LC-LA = -2 dB). M =
Medium frequency attenuation value (predicted noise level reduction for noise where LC-LA = +2 dB). L = Low
frequency attenuation value (predicted noise level reduction for noise where LC-LA = +10 dB).
6
SNR = Single Number Rating (the value that is subtracted from the measured C-weighted sound pressure
level, LC, in order to estimate the effective A-weighted sound level inside the ear).
