A hearing protection system including an earplug moveably displaceable in a plane covering an ear of a user from an open position to a closed position in response to a signal received from a trigger mechanism. When in the open position, the earplug is positioned adjacent to the ear of the user to allow the user to hear ambient sound at an unchanged volume. When in the closed position, the earplug is positioned over the ear of the user to at least partly block the ambient sound and allow the user to hear the ambient sound at a reduced volume that is less than the unchanged volume.
