Abstract:
1. A method for operating a hearing aid device or hearing device system, comprising: generating a first microphone signal from at least one first microphone; deriving one or more first identified oscillation values from the first microphone signal comprising characteristic quantities of the microphone signal that are relevant for recognizing oscillations; generating a second microphone signal from at least one second microphone that is distanced from the at least one first microphone; deriving one or more second identified oscillation values from the second microphone signal comprising characteristic quantities of the microphone signal that are relevant for recognizing oscillations; transmitting the first identified oscillation values over a communication link between the first and second microphone after deriving the first identified values and subsequently inputting these values into a comparison unit associated with the second microphone; inputting the second identified oscillation values into the comparison unit associated with the second microphone; comparing the first identified oscillation values and the second identified oscillation values within the comparison unit; recognizing feedback-conditioned oscillations based on the comparing; and reducing the feedback-conditioned oscillations when they are recognized as such.
