Earplugs

 

— hearing protection devices; The name comes from the phrase "take care of your ears." Earplugs are plugs that are inserted directly into the canal of each ear and reduce the volume of sound heard by a person. Such devices are indispensable when working with engines and other noisy mechanisms, during shooting, blasting, etc. At the same time, compared to other devices of a similar purpose — headphones — earplugs are much more compact; besides, they are compatible with almost any other protective equipment (whereas the “ears” can be uncomfortable when worn, for example, with a full face mask). Moreover, the headphones can be supplemented with earplugs for maximum sound isolation.

Note that classic earplugs are designed to protect mainly against low-frequency noise. However, this category may also include antiphons, devices of a similar use, tuned to filter high frequencies. There are earplugs with specific design features — for example, a through channel of a special shape, through which you can hear the human voice quite clearly while maintaining noise-protective properties.
