3M Peltor Optime 105 Over-the-Head Earmuff

3M™ PELTOR™ Optime™ 105 Over-the-Head Earmuffs

The 3M™ PELTOR™ Optime™ 105 Over-the-Head Earmuffs are engineered to deliver high-performance hearing protection in the most extreme noise environments, with exposure levels reaching up to 105 dBA. These earmuffs feature a unique double-shell earcup design—two cups connected by a foam inner layer—to enhance noise attenuation across a broad range of low and high frequencies.

Key Features:

• High-Level Hearing Protection: Designed for environments with noise levels up to 105 dBA, offering robust attenuation through a combination of added mass, volume, and double-shell technology.

• Double-Shell Earcup Design: Improves overall noise reduction by combining two interconnected cups with a foam inner layer for superior acoustic performance.

• Durable Stainless Steel Headband: Resists bending and warping while distributing weight evenly for a secure, low-pressure fit.

• Enhanced Comfort: Pivoting earcup attachment points work with the lightweight headband to ensure a snug and comfortable fit. Soft, liquid and foam-filled cushions create an effective noise-blocking seal against the head.

• Noise Reduction Rating (NRR): The NRR provided under optimal conditions may not reflect real-world performance. For typical use, 3M recommends reducing the NRR by 50% when estimating actual protection.

Performance & Compliance:

• Noise Reduction Rating (NRR): 29 dB (when properly fitted)

• OSHA Compliance: Suitable for hearing conservation programs in accordance with OSHA guidelines

• Tested According to: ANSI S12.6-1997 (R2002), Method B

Application Areas:

• Heavy industrial environments

• Manufacturing plants

• Airports and aviation maintenance zones

• Mining and metalworking facilities

• Any worksite with continuous high-decibel machinery
