These earplugs come with 2 plugs per set. They are rated to have a noise reduction rating of 26 decibels. Earplugs are small inserts that fit into the outer ear canal. They must be snugly sealed so the entire circumference of the ear canal is blocked. An improperly fitted, dirty or worn-out plug may not seal and can irritate the ear canal.
