An earplug is a device that is inserted in the ear canal to protect the user's ears from loud noises, intrusion of water, foreign bodies, dust or excessive wind. Since they reduce the sound volume, earplugs may prevent hearing loss and tinnitus (ringing of the ears), in some cases.[1][2]

US Occupational Safety and Health Administration requires hearing conservation programs which include the provision of hearing protection devices (HPDs). But this does not mean that OSHA considers HPDs to be effective.[3]

They may not work effectively because of the difficulty in getting acceptable fit for each individual. In some cases-particularly when noise is intermittent and below 85 dB(A) - they may make communication more difficult, which can contribute to accidents and make jobs more difficult to perform.
