Key
APVf = Assumed Protection Value
Mf = Mean attenuation value
sf = Standard deviation
H = High-frequency attenuation value (predicted
noise level reduction for noise with L(C) – L(A)
= -2dB)
M = Medium-frequency attenuation value (predicted
noise level reduction for noise with L(C) – L(A)
= +2dB)
L = Low-frequency attenuation value (predicted noise
level reduction for noise with L(C) – L(A) = +10dB)
SNR = Single Number Rating (the value that is
subtracted from the measured C-weighted sound
pressure level, L(C) in order to estimate the effective
A-weighted sound pressure level inside the ear).
