An earplug is an object made of soft material that fits snugly in your ear to protect your ear from damage caused by loud noise. Earplugs come in various shapes and sizes and can be custom made to provide the best protection. Some earplugs should only be used once (single use earplugs) while others can be reused many times.
An earplug is a device that is meant to be inserted in the ear canal to protect the wearer's hearing from loud noises or the intrusion of water, foreign bodies, dust or excessive wind.
