Abstract
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.
