Ear Muff are protective devices worn over the ears to reduce exposure to hazardous noise levels, thereby preventing hearing damage and loss. It typically consists of ear cups lined with sound-absorbing materials, such as foam or liquid-filled cushions, which create a seal around the ears. They are commonly used in industrial settings, construction sites, shooting ranges, and other noisy environments. Proper selection, fit, and maintenance of ear muffs are crucial to safeguarding workers' hearing health and ensuring compliance with occupational safety regulations. Ear Muff typically consists of a headband and two ear cups filled with thermal insulation or soundproofing material.
