The present invention provides a hearing protection earphone, a hearing protection method and a computer program storage medium, comprising a sound control system including a wearing-status sensing module for monitoring a current wearing status of the hearing protection earphone, sending a first monitoring signal when it is determined that the hearing protection earphone is in a wearing state, and sending a second monitoring signal when it is determined that the hearing protection earphone is in a non-wearing state; and a main control module for enabling a play function corresponding to a play mode which is adapted to the hearing protection earphone currently when the first monitoring signal sent from the wearing-status sensing module is received, and counting a stand-by time of the protection earphone and turning off the hearing protection earphone after a preset stand-by time elapses when the second monitoring signal sent from the wearing-status sensing module is received.
