In a signal processing unit (a) of a hearing device (1) the signal processing unit (8) consisting of a signal analyzing unit (9) and a signal identification unit (10), the momentary acoustic surround situation is identified. Based on this identified surroun situation, the parameter set (7) belonging to the identified surround situation is automatically adjusted in a transmission unit (5) in which a number of parameter sets are saved which are assigned to different acoustic surround situation. The hearing device user can adjust his individual hearing desire for each acoustic surround situation according to the automatic adjusted parameter set with the aid of an input unit (11). Thereby, the parameter of this parameter set are adjusted at the same time and commnnly in one of two opposing directions, e.g. in the sense of “better hearing” or in the sense of “more pleasant understanding”.
