Responsible manufacturer: Sordin AB, Rörläggarvägen 8, SE-331 53 Värnamo, Sweden, tel: +46-370-69
35 50.
f = Frequencies at which attenuation is measured
M
f
= Mean value
s
f
= Standard deviation
APV (M
f
–s
f
) = 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)
W = Weight (gram)
CRITERION LEVELS (Table 4)
Typical values in accordance with EN 352-4:2001/A1:2005, appendix A, with the volume set to maximum.
H = High frequency sound pressure level (L
C
–L
A
= 1.2 dB),
M = Medium frequency sound pressure level (L
C
–L
A
= 2 dB),
L = Low frequency sound pressure level (L
C
–L
A
= 6 dB).
