Earmuffs 3M Optime III, H540A-461-GB, 35dB SNR
3M Optime III are earmuffs that protect your ears from various harmful noises – industrial or other.
The safety of the Earmuffs 3M Optime III, H540A-461-GB is based on the innovative double cup technology, which minimizes resonance inside the capsule and provides maximum high-frequency insulation.
The earmuffs have an SNR (single number rating) of 35 decibels (dB), meaning they can isolate noises up to 35dB.
Earmuffs 3M Optime III, H540A-461-GB is a super-muff and has been developed for use in extremely noisy environments.
TECHNOLOGY: The protection is based on a technology with a double casing that minimizes resonance in the holder casing. This results in maximum high-frequency muffling while at the same time it’s still easy to understand speech and signals. Correctly worn, they significantly reduce exposure to hazardous levels of noise and sound levels. An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling.
COMFORT: The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure. Soft wide cushions help reduce pressure around the ears and improves comfort and wearability.
NOISE REDUCTION: Earmuffs 3M Optime III, H540A-461-GB has one of the highest noise reduction ear muffs on the market. EN 352-1: 1993.
