The four basic types of ear protection are foam earplugs, premolded earplugs, canal caps, and earmuffs. Foam earplugs expand inside the ear canal for a snug fit. Premolded earplugs provide reusable protection. Canal caps rest at the ear opening, and earmuffs cover the entire outer ear for broader noise reduction.
