3M Over-The-Head Industrial Ear Muffs, Noise Reduction Rating NRR

Ear muffs fit over the ears to protect against potentially harmful sound levels that can cause hearing loss. These safety ear muffs consist of a headband with padded ear cups that seal around the ears to provide hearing protection by dampening surrounding noise. Compared to ear plugs, ear muffs provide a longer life and a more consistent fit for reaching their optimal noise reduction rating (NRR). They're also more visible than ear plugs for confirming that workers are complying with hearing safety rules. Protective ear muffs are ideal for environments with intermittent noise because they can rest around your neck when they're not in use and don't require rolling to reequip. Pair them with ear plugs to improve the NRR by 5 decibels (dB).

Impulse noise protection ear muffs (also called electronic ear muffs) electronically filter out constant, loud noise and short bursts of high-volume noise. These electronic hearing protection ear muffs reduce, or attenuate, loud noises while still allowing you to hear ambient sound. Electronic ear protection is often worn to protect against impulse (or impact) noises such as gunfire or metal stamping, pressing, and forging sounds.
