Model ACS-ER9 - Reusable Hearing Protectors
Model SNR H M L
ER9 10dB 10dB 8dB 8dB
H: Average attenuation characteristics in high frequency spectrum (> 2 kHz)
M: Average attenuation characteristics in mid frequency spectrum (0.5 - 2 kHz)
L: Average attenuation characteristics in low frequency spectrum (< 0.5 kHz)
SNR (Single Number Rating): Average attenuation characteristics in the standard
frequency spectrum.
Note for ER9 : At some frequencies the APV (Assumed Protection Value) is
below the minimum attenuation required by EN352-2. Therefore the CE standard
is not applicable to this model. Ammendment to 352-2:2002 should be added
for a non-standard class of hearing protector applicable to the ER9, provided that
'a reliable risk assessment is made prior to selection of this class of ear-plug'.
