3M™ Peltor Optime™ III Earmuff is a high performance hearing protector for use in extremely noisey environments. The earmuff protection is designed with a double casing minimising resonance in the holder casing, maximising high-frequency attenuation.An acoustic connection between the inner volume and the volume between the casings in its turn provides low-frequency attenuation.
Sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure,which gives effective protection and highest comfort for the wearer.
Attenuation: Headband: SNR=35dB, H=34dB, M=29dB, L=20dB
