f = Frequencies at which attenuation is measured
M = Mean value
f
s = Standard deviation
f
APV (M –s ) = Assumed Protection Value
f f
H = High frequency attenuation value (predicted noise level reduction for noise where L
M = Medium frequency attenuation value (predicted noise level reduction for noise where L
L = Low frequency attenuation value (predicted noise level reduction for noise where L
SNR = Single Number Rating (the value that is subtracted from the measured C-weighted sound pressure
level, L , in order to estimate the effective A-weighted sound level inside the ear)
C
W = Weight
CRITERION LEVELS (Table 4)
Typical values in accordance with EN 352-4:2020 with the volume set to maximum.
H = High frequency sound pressure level (L
M = Medium frequency sound pressure level (L
L = Low frequency sound pressure level (L
