Abstract:
A hearing device, e.g. a hearing aid, comprises a forward path for processing an electric signal representing sound including a) an input unit for receiving or providing an electric input signal representing sound, b) a signal processing unit, c) an output transducer for generating stimuli perceivable as sound to a user, d) a feedback detection unit configured to detect feedback or evaluate a risk of feedback via an acoustic or mechanical or electrical feedback path from said output transducer to said input unit and comprising d1) a magnitude and phase analysis unit for repeatedly determining magnitude, Mag, and phase, Phase, of said electric input signal and further parameters based thereon, and d2) a feedback conditions and detection unit configured to check criteria for magnitude and phase feedback condition, respectively, based on said values, and to provide a feedback detection signal indicative of feedback or a risk of feedback.
