Wearing Hearing Protection Devices


Earmuffs fit over the outside of the ears. Because their effectiveness is limited to the quality of the seal around your ear, they are often not as effective as earplugs. For this reason, a combination of earplugs and earmuffs are used in some work environments.

When using earmuffs:
- Make sure that the earmuffs fit snugly around   your ears.
- Consider using earplugs if you wear glasses,   earrings, or have facial hair that would prevent   the earmuffs from forming a good seal around   your ears.
