1. An earplug with a body that has an axis and a passage extending parallel to its axis, that has a body front sealing portion that fits in and seals to the walls of a human ear canal, and that has a body rear portion that lies outside the ear canal, wherein:

  • said body rear portion has a slot that extends in a lateral direction which is primarily perpendicular to said axis and that intersects said passage; and

    includinga blocking member with a hole, said blocking member being moveable along said slot between an unblocking position wherein at least part of said hole is aligned with said passage so said blocking member does not completely block said passage, to thereby allow sound to flow from the environment and through said passage to the ear canal, to a blocking position wherein said hole is completely out of alignment with said passage and said blocking member blocks said passage to prevent almost all sound in the environment from reaching the ear canal.
