Abstract (en)

[origin: US2011150250A1] A method operates a hearing device having at least two omnidirectional microphones emitting microphone signals and a detection unit for defining acoustic feedback. The method includes connecting a first electrical connection of the microphones to one another in order to form a first signal with directional effect, an adjustment of the directional effect of the first signal such that the acoustic feedback in the first signal is maximized, and an analysis of the first signal by the detection unit for defining the acoustic feedback. It is advantageous that the feedback can be detected by a signal with an improved signal-to-noise ratio. Feedbacks are therefore recognized more reliably and more rapidly.
