E-A-Rfit™ provides an accurate quantitative assessment of how much noise reduction a hearing protector provides to an individual worker.???????

• Effective hearing protection for noise exposures up to 105dBA
• Double-shell technology boosts its noise blocking ability
• Durable stainless steel headband resists bending and warping
• Noise Reduction Rating (NRR) of 30 dB*, highest available in over-the-head style earmuffs
• 3M™ Peltor™ Optime™ 105 over-the-head earmuffs feature double-shell technology to provide effective hearing protection.

The 3M™ Peltor™ Optime™ 105 Over-the-Head Earmuff has been developed for effective hearing protection in the most demanding noise environments where noise exposures are expected to reach as high as 105 dBA. The Optime™ 105 over-the-head earmuff features added mass and volume, plus a unique “double-shell” earcup design (two cups connected via foam inner layer) to boost the noise reduction throughout the full range of low and high frequencies. The durable stainless steel headband resists bending and warping and distributes weight for a low-pressure fit. The lightweight headband works in conjunction with earcup pivot points that tilt to maximize wearer comfort. Soft, liquid &foam filled cushions help the earmuffs fit comfortably against the head to help provide an effective noise-blocking seal.
