Abstract
For reducing feedback-conditioned oscillations in a hearing aid device, microphone signals of a first microphone and of a distanced, second microphone are compared to one another. When oscillations are detected at the same frequency in both microphone signals, these oscillations are determined to be useful (non-feedback) tonal signals. Oscillations that are only present in one of the microphone signals, in contrast, are feedback-conditioned and are suppressed using suitable measures.
Claims16
A method for operating a hearing aid device or hearing device system, comprising:
- generating a first microphone signal from at least one first microphone;
- generating a second microphone signal from at least one second microphone that is distanced from the at least one first microphone;
- comparing the first microphone signal and the second microphone signal;
- recognizing feedback-conditioned oscillations based on the comparing;
- and
- reducing the feedback-conditioned oscillations when they are recognized as such.
A hearing aid device or hearing device system, comprising:
- at least one first microphone configured to generate a first microphone signal;
- at least one second microphone distanced the first microphone configured to generate a second microphone signal;
- a signal processing unit configured to process the first microphone signal and the second microphone signal;
- a comparison unit configured to compare the first and second microphone signals or signals derived from them and to recognize feedback-conditioned oscillations;
- and
- a feedback-conditioned oscillation reducer.
