Protect Your Hearing in High-Noise Industrial Settings
The 3M Peltor Optime 105 Behind-the-Head Earmuff delivers robust hearing protection with a 29 dB Noise Reduction Rating (NRR). Its patented double-shell technology significantly boosts noise-blocking capabilities, making it suitable for environments with noise levels up to 105 dBA. This model is specifically designed for industrial and occupational use, offering reliable sound isolation for demanding tasks.
Engineered for comfort and durability, these earmuffs feature soft, foam-filled cushions and a stainless steel construction that resists bending and warping. The behind-the-head design ensures compatibility with hard hats, a crucial feature for many industrial settings. The earmuffs are also testable with the 3M E-A-Rfit Dual-Ear Validation System for precise fit confirmation.
While the NRR is rated at 29 dB, 3M recommends reducing this figure by 50% for estimating actual noise reduction in typical use. These earmuffs are ideal for sectors like construction, manufacturing, transportation, and oil & gas. All customs duties and GST are included in the listed price, with delivery via ExpressBox tracked shipping to your pincode.
Engineered for Extreme Noise
3M Peltor's Optime 105 earmuffs utilize patented double-shell technology to deliver a high Noise Reduction Rating (NRR) of 29 dB. This advanced design effectively mitigates noise from sources up to 105 dBA, offering superior protection in environments like construction sites, airports, and heavy manufacturing plants. Unlike standard earmuffs, the dual-shell system provides enhanced sound isolation, ensuring your hearing is safeguarded during demanding tasks. This level of protection is critical for maintaining long-term auditory health in noisy industrial settings.
Ideal for Industrial Work, Not for Casual Use
These earmuffs are built for rigorous occupational use, featuring a durable stainless steel construction and a comfortable behind-the-head design that fits with hard hats. They are perfect for professionals in construction, manufacturing, or transportation who require maximum noise reduction. However, they are not intended for consumer use or casual noise reduction needs. If you need earmuffs for everyday tasks or sensitive hearing, consider models designed for lighter noise environments or specific consumer applications.
