Abstract
A hearing system includes a hearing device with an input acoustical/electrical converter. The system is controllably operable in at least first and second modes. A sensing unit senses behavior of an acoustical impedance of an acoustical input of the input converter. An evaluation unit evaluates the sensed behavior over at least one predetermined behavior of the acoustical impedance. An output of the evaluation unit controls change over from the first mode to the second mode.
