1. A hearing system comprising:
- at least one ear-applicable hearing device with an input acoustical/electrical converter arrangement, anda switching unit being switchable by an individual who controls said hearing device in a first stable operating status as desired by said individual or in at least one second stable operating status as desired by said individual, so as to adapt said hearing system by said individual to a respectively desired operating status, whereby said first and second stable operating statuses are different and are perceived by the individual as being different, said hearing system comprising a sensing unit sensing operating stability and operating instability of an acoustical feedback loop including said hearing device applied to said individual, said sensing unit controlling switch-over from said one desired to said at least one second desired operating status whenever instability of said feedback loop is sensed, said instability being willingly established by said individual at a desired moment and removed by said individual at a second desired moment so as to control said switch-over by the willingly applied instability.

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.

8. A method for manually controlling a hearing system with a hearing device, to switch over from one desired operating mode of the hearing device to at least one other desired operating mode of the hearing device, comprising the steps of:
-
providing the hearing device, wherein the hearing device is worn by an individual; willingly establishing, by the individual, an instable operating mode of the hearing device, wherein the instable operating mode is established by manually applying a member adjacent to and/or to said hearing device; changing from the one desired operating mode of the hearing device to the at least one other desired. operating mode of the hearing device upon the hearing device sensing the instable operating mode; and
willingly ceasing, by the individual, the instable operating mode of the hearing device after changing from the one desired operating mode of the hearing device to the at least one other desired operating mode of the hearing device.

9. A method for manually controlling a hearing system with a hearing device, to switch over from one desired operating mode of the hearing device to at least one other desired operating mode of the hearing device, comprising the steps of:
-
providing the hearing device, wherein the hearing device is worn by an individual; willingly establishing, by the individual, an instable operating mode of the hearing device, wherein the instable operating mode is established by manually applying a member adjacent to and/or to said hearing device; changing from the one desired operating mode of the hearing device to the at least one other desired operating mode of the hearing device upon the hearing device sensing the instable operating mode; and willingly ceasing, by the individual, the instable operating mode of the hearing device.
