What kind of hearing protection might be used in noisy environments?

In noisy environments, earplugs or earmuffs serve as effective hearing protection by reducing the noise exposure to an individual's ears. Earplugs are inserted into the ear canal and can block out significant sound levels, while earmuffs cover the entire ear and form a seal to prevent noise from entering. Both options are specifically designed to minimize the risk of hearing damage caused by prolonged exposure to loud sounds in industrial settings.

Safety glasses, hard hats, and respirators do not provide any hearing protection. Safety glasses protect the eyes from flying debris or splashes, hard hats protect against head injuries from falling objects, and respirators are designed to filter out harmful particles or gases from the air. Therefore, earplugs or earmuffs are the appropriate choice for safeguarding hearing in environments with high noise levels.
