What 3M hearing protection is and how it works

3M hearing protection covers a broad range of earplugs and earmuffs designed to help reduce the level of sound reaching the ear when used as directed, as described in 3M product literature3M, 01/2025.

Disposable foam earplugs typically use soft, slow-recovery foam that is rolled, inserted into the ear canal, and allowed to expand to form a seal against the ear canal walls, according to manufacturer guidance3M, 09/2024.

Earmuff style protectors use cushioned ear cups that cover the outer ear and rely on a combination of rigid shells and soft cushions to help block sound paths to the ear canal, as explained in US Occupational Safety and Health Administration (OSHA) training materialsOSHA, 04/2024.

Occupational noise exposure is a key cause of preventable hearing loss in US workers, and federal regulators require employers to provide hearing protection when noise exceeds specific limitsOSHA, 04/2024.

NIOSH states that long term exposure to loud sound can contribute to permanent hearing damage and tinnitus, and it recommends properly fitted hearing protection as part of a hearing loss prevention programCDC/NIOSH, 06/2024.

For US consumers, hearing protectors are also relevant in recreational activities such as lawn mowing, power tool use, motorsports, and firearm use, as highlighted in public guidance from the American Speech-Language-Hearing AssociationASHA, 03/2024.
