WARNING!
Hearing protectors complying with EN 352-1 are of 'medium size range', 'small size range' or 'large size range'.
'Medium size range' hearing protectors will fit the majority of wearers. 'Small size range' or 'large size range'
are designed to fit wearers for whom 'medium size range' hearing protectors are not suitable.
ATTENUATION DATA (table 2 & 3)
The attenuation values of the hearing protectors are tested according to EN 4869-2:2018 (with the
electronics switched off) and the results are noted in the table 2 & 3. Explanation:
75300 Supreme Basic Headband
75301 Supreme Basic AUX Headband
75302 Supreme Pro Headband
75302-X Supreme Pro-X Headband
75302-X LED Supreme Pro-X LED Headband
76302 Supreme Pro Neckband
76302-X Supreme Pro-X Neckband
Attenuation value explanation:
f = Frequencies where attenuation value 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 with L
M = Medium frequency attenuation value (predicted noise level reduction for noise with L
L = Low frequency attenuation value (predicted noise level reduction for noise with L
SNR = Single Number Rating (the value which is subtracted from the measured C-weighed sound pressure
level, L , in order to estimate the effective A-weighted sound pressure level inside the ear)
C
W = Gross weight of the hearing protector in gram, not including batteries
CRITERION LEVELS (table 4) Supreme Basic Line / Supreme Pro Line
Typical values in accordance with EN 352-4:2001/A1:2005, appendix A, with the volume set to
maximum. Table 4 key:
H = High frequency sound pressure level (L
M = Medium frequency sound pressure level (L
L = Low frequency sound pressure level (L
