Description Noise protection ear muffs 3m optime iii head version h540a

The 3M PELTOR Optime III earmuff was developed as a high-performance hearing protector for use in environments with the highest noise levels, i.e. airports, ship engine rooms, power plants and printing plants. A hearing protector that provides maximum high-frequency attenuation. Designed for use in environments with intense noise or situations, and when concentration requires protection from distracting sounds. It provides maximum low-frequency attenuation thanks to a special acoustic connection between the inner space and the space between the earcups, and the large space inside the earcup canopy helps reduce moisture and heat buildup. The perfect fit is ensured by a wide, soft, coated headband. Their attenuation level is 35 dB.
