3M Peltor Optime III H540A Headband Ear Muffs
Description Headband option. The 3M Peltor Optime III ear muffs have been developed for use in extremely high noise environments, particularly those dominated by low frequency sounds. The protection is based on a technology with a double casing minimising resonance in the holder casing resulting in maximum high-frequency attenuation. An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency attenuation. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure. The 3M Peltor Optime III ear muff stands for effective protection and highest comfort for the wearer. The product is also available in di-electric version without visible metal parts and in Hi-Viz green for workers who need hearing protection and be extra visible – on road construction sites, airports or other high-risk workplaces. Ear muff may be helmet mounted. Hygiene kit available.
