For more information about the contents of the technical
data, refer to the list that follows:
• F = Frequencies at which attenuation is measured.
• Mf = Mean value.
• Sf = Standard deviation.
• APV (Mf-Sf) = Assumed Protection Value.
• H = High frequency attenuation value (predicted
noise level reduction for noise where L
C
-L
A
= -2 dB).
M = Medium frequency attenuation value (predicted
noise level reduction for noise where L
C
-L
A
= +2 dB).
L = Low frequency attenuation value (predicted noise
level reduction for noise where L
C
-L
A
= +10 dB).
• 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 level inside the ear.
