| An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling |
| and has been developed for use in extremely noisy environments |
| Attenuation: SNR 35dB, H 40dB, M 32dB, L 23dB |
| Broad sealing rings filled soft plastic foam |
| Double casing technology for maximum high and low frequency muffling |
| Ear protection for extreme noise environments |
| Effective protection and best comfort are the hallmarks of Optime III. SNR = 35dB |
| H = 40dB |
| L = 23dB |
| M = 32dB |
| Optime III Extreme noise protection for long and short spells of use |
| Optime III is a super-muff |
| 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 |
| The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure |
| while at the same time its still easy to understand speech and signals |
