What are Safety Ear Plugs?
Safety ear plugs serve two main purposes — to keep loud, harmful sounds out of the ear, or to keep water out of the ear. Some ear plugs are only used for sound. Others can be used for both purposes. It is important to understand what limitations a pair of safety ear plugs may have before purchasing them. Under most circumstances, safety ear plugs are used in environments where a person may be subjected to constant loud noises. To protect workers, foam ear plugs are standard issue in some industrial settings. These are very cheap to produce, reusable, and are effective at blocking sound.
