The invention relates to a hearing-protection device for deadening sounds, selectively based on frequency, comprising a housing which can be inserted into the external auditory canal of a person. Said housing contains a communication route for sounds, consisting of at least one chamber (26) and at least one channel (11; 23a, 23b, 23c, 23d) with a predetermined cross- sectional course which opens into said chamber (26). The invention is characterised in that a moveable element is provided which can be displaced into a multitude of positions, thus varying the cross-sectional course and/or the length of the channel (11; 23a, 23b, 23c, 23d).
