Which hearing protection device provides coverage around the entire ear?

• A. Foam earplugs
• B. PVC earplugs
• C. Earmuffs
• D. Ear canal shields

Answer: (C)

Coverage around the entire ear means the protection forms a seal around the outside of the ear so sound can’t reach the eardrum from the sides or top. Earmuffs achieve this by using two cushioned cups that fit over each ear and are held together by a headband, creating an external seal around the ear. Foam and PVC earplugs, on the other hand, are designed to go into the ear canal and seal from the inside, not around the ear itself. They don’t surround the outer ear, so they don’t provide full coverage. Ear canal shields aren’t built to wrap around the outer ear either; they cover the opening of the ear canal but still don’t envelop the entire ear. Because earmuffs completely encase the ear and establish a surrounding seal, they are the best option for coverage around the entire ear.
