ATTENUATION VALUES

SNR = 37dB H = 37 dB M = 34 dB L = 31 dB

Legend: 

APVf(dB) = Mf –sf (dB)

Mf= mean attenuation value sf = standard deviation APVf = assumed protection value

H= high frequency attenuation value

M= mid-frequency attenuation value

L= low frequency attenuation value

SNR= single reduction index (the value subtracted from the C-weighted sound pressure level, L(C), to calculate the effective A-weighted sound pressure level in the ear canal)

APPLICATIONS

Its use is suggested for lower range noise levels
