The 3M™ Peltor™ Optime Earmuffs have been viewed as a standard in the hearing protection industry. They incorporate:
- acoustic engineering
- wearer-focused comfort design
- performance versatility
The 3M™ Peltor™ Optime Earmuffs are recommended for high-noise exposure situations; eight-hour TWA noise exposures up to 105 dBA.
Earmuffs must fully enclose the ears to seal against the head
The Optime 105 earmuffs feature a “double-shell” cup design that helps improve attenuation across the entire range of frequencies.
Earmuff Tips:
- Adjust the headband so cushions exert even pressure around the ears to get the best noise reduction.
- Pull hair back and out from beneath the cushions.
- Don’t store pencils or wear caps under cushions.
- Thick or poorly fitting eyeglass temples may also cause some loss in noise reduction.
Cushions can be cleaned with warm soapy water and rinsed thoroughly
- Do not use alcohol or solvents.
- Cushions normally need replacing at least yearly, or whenever they become stiff, cracked, or no longer seal.
- Don’t modify earmuffs in any way, and especially do not stretch or abuse the headbands as this will reduce your protection.
