3M OPTIME III ear muffs for maximum attenuation in environments with extremely high noise levels (dominated by low frequencies), such as airports, ship engine rooms, power plants, printing houses, heavy industry. The protection is based on a double casing technology which minimizes resonance in the supporting casing.
The result is a maximum SNR attenuation of 35 dB. The acoustic connection between the internal space and the space between the cabinets ensures maximum attenuation of low frequencies. The large space inside the ear cup helps to reduce moisture and heat build-up.
Wide, comfortable sealing rings are filled with a combination of liquid and foam for optimal sealing while reducing pressure.
