Earmuffs only deliver their rated protection when the cushions form an unbroken seal against your head. This guide shows you how to wear earmuffs correctly: positioning the headband, clearing hair and eyewear arms, setting the right tension, choosing cap-mount versus over-head styles, and knowing when worn cushions need replacing.

The right protector is the one a worker will actually wear all shift while still getting below 85 dBA. This guide shows you how to choose hearing protection: matching derated NRR to your noise level, comparing earplugs, earmuffs, and banded plugs, weighing comfort and communication needs, and knowing when to double up devices.

A decibel levels chart turns noise numbers into a clear picture of when hearing damage starts and when protection becomes mandatory. This guide charts common tools and environments by dBA, lays out the OSHA 1910.95 permissible exposure limits hour by hour, and shows how to convert a noise level into the right earplug or earmuff NRR.
