For more information about the contents of the technical
data, refer to the list that follows:
• 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

= +10
dB).
• SNR = Single Number Rating (the value that is
subtracted from the measured C-weighted sound
pressure level, L
