Which of these is NOT a type of hearing protection?

Hearing protection is essential in various environments to safeguard against noise-induced hearing loss. Among the options provided, surgical masks are designed primarily to protect against airborne pathogens and particulate matter rather than to guard hearing. They serve a different function entirely and do not provide any noise attenuation.

In contrast, disposable plugs, reusable plugs, and earmuffs are all designed specifically to reduce sound exposure. Disposable plugs are made from foam or similar materials, used once and then discarded; reusable plugs can be washed and used multiple times, making them cost-effective for continued use; and earmuffs typically provide a higher level of noise reduction, as they cover the entire outer ear. Understanding the specific purpose of each type of equipment underscores why surgical masks do not belong in the category of hearing protection.
