3M Peltor Optime III H540P3E-413-SV Helmet Mounted Ear Defenders are high performance ear muffs. Designed to protect your employees hearing when operating heavy machinery or working in noisy environments. For example, building and construction sites, airports, machine shops and more. These ear muffs have a P3E attachment, for use with MSA safety helmets. The Optime III ear muffs effectively reducing noise levels up to 34 decibels (SNR), using double casing technology that minimises resonance in the holder casing. This results in maximum high-frequency muffling, while at the same time it is still easy to understand speech and signals. The large cups also reduce the build up of heat and moisture, helping to keep the wearer comfortable.
