3M ear muffs (notably the PELTOR line) are high-performance hearing protection devices designed for industrial and high-noise environments. They offer Noise Reduction Ratings (NRR) generally ranging from 21 dB to over 30 dB, featuring foam-filled cushions, adjustable headbands or helmet attachments, and double-casing technology to minimize resonance.
Key Features & Description:
High Attenuation: Designed to protect against hazardous noise in environments like airports, construction sites, and manufacturing.
Comfort Design: Soft, wide foam cushions reduce pressure around the ears and feature large internal space to minimize heat and moisture build-up.
Structure: Available in headband, neckband, and helmet-mounted (hard hat).
