A hearing aid device has a directional microphone system with a first microphone outputting a first microphone signal and a second microphone outputting a second microphone signal. A delay unit generates a directivity by delaying the second microphone signal or a fourth microphone signal derived therefrom by an internal time delay and associating it with the first microphone signal or a third microphone signal derived therefrom for generating a directional microphone signal. A cross-correlation analysis unit receives the first or the third microphone signal and the second or the fourth microphone signal and determines a value of a cross correlation of the two microphone signals. A control unit adjusting the time delay depending on the value of the cross correlation of the two microphone signals. A classifier determines audio conditions in which the hearing aid device is currently situated, and the time delay is adjusted depending on the audio conditions.

The adjustment of a hearing device is to be improved and configured in a more user-friendly fashion. To this end, a method is proposed whereby the hearing device is set individually to the user and is inserted at least partially into the auditory canal of the user. Finally an in-situ measurement of the acoustic impedance of the auditory system of the user including at least part of the auditory canal of the user is implemented with a tympanometric method. An automatic correction of the individual setting of the hearing device can take place on the basis of the results of the in-situ measurement.

A circuit for operating a hearing device with a variable operating parameter is disclosed. A storage device for storing operating parameter settings in a starting situation as well as in a target situation and a control unit, which implements a matching of the operating parameter according to a setting of the starting situation to the operating parameter settings of the target situation, is provided. Further, a connection device for connection to a control element and a data processing device for influencing the operating parameter by a user of the hearing device, is provided. The control unit performs the matching of the operating parameter with a minimal matching rate in time segments in which the operating parameter is often influenced by the control element or data processing device, and with a higher matching rate in time segments, in which the operating parameter is rarely influenced or not influenced at all by the control element or data processing device.
