3M Peltor Optime 3 Headband Ear Protection Ear Muffs 35db- H540A
• Optime III is a super-muff, and has been developed for use in extremely noisy environments.• The protection is based on a technology with a double casing that minimises resonance in the holder casing. This results in maximum high-frequency muffling, while at the same time its still easy to understand speech and signals.
• An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling.
• The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure.
• Effective protection and best comfort are the hallmarks of Optime III.
• SNR 35db
