3M | EarMuff Peltor 105 Optime (Ear Defender)

3M™ Peltor™ Optime™ 105

• Over-the-head earmuffs feature double-shell technology to provide effective hearing protection
• The 3M™ Pelter™ 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
• *The Noise Reduction Rating (NRR) may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided
• The 3M™ Pelter™ Optime™ number (105) is a 3M guideline for the maximum time-weighted average A-weighted exposures in which the product, when properly worn and in good condition, can provide adequate protection to meet OSHA hearing conservation guidelines
• However, the user must make sure that the specific earmuff and style selected provides appropriate protection
• To be effective, the hearing protector should be used within a hearing conservation program that also includes noise level assessments by qualified personnel, training, audiometric testing and engineering controls
• 3M™ Optime™ recommendations are based upon testing per Method B of the most recent ANSI standard, S12.6-1997 (R2002)
• Method B provides data that approximate the upper limits to attenuation that can be expected for groups of occupational users
• Properly trained and motivated individuals can potentially obtain greater protection
• 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
• Size Fits Most
