Hearing protection Peltor Red OPT3

3M Peltor Optime III is a hearing protection developed for very noisy environments. Extra sound attenuation for both low and high frequencies, intended for noise with particularly high sound levels. A double shell minimises resonances in the enclosure shell. High frequency attenuation is maximised while still allowing easy perception of speech and signals. In turn, an acoustic coupling between the inner volume and the volume between the shells maximises low-frequency attenuation.
