Abstract: A method for the operation of a hearing device with at least one receiver includes carrying out a fixed second frequency shift of an electrical receiver signal supplying the receiver or of a predefinable frequency range of the receiver signal and a variable first frequency shift of the receiver signal or of a predefinable frequency range of the receiver signal. The first frequency shift is changed depending on the occurring feedback. A frequency shift which effectively prevents feedback is advantageously carried out, while artifacts of the frequency shift are minimized.

Abstract: A hearing device has a signal-processing apparatus for processing an input signal into an output signal, and a feedback-canceller apparatus for reducing feedback artifacts on the basis of the input signal and the output signal. The feedback-canceller apparatus has an adaptive, first filter, for establishing a set of filter coefficients for a predefined feedback situation. The feedback-canceller apparatus is configured to store the set of filter coefficients. It has at least one second filter, which can be operated directly parallel to the first filter on the basis of the stored set of filter coefficients. The adaptive, first filter can be continuously adapted to a current feedback situation, and the feedback-canceller apparatus is configured such that in the current feedback situation it automatically selects either the first or the second filter. As a result, it generally only requires a simple switchover, but not a complete adaptation.

Abstract: A hearing device with a plurality of microphones is intended to be able to be continued to be operated sensibly, even if a microphone fails. Therefore, a hearing device, and in particular a hearing aid, is proposed which provides a decision unit for deciding whether one of the microphones is defective, and a signal processing unit for processing the signals from the microphones using a plurality of processing algorithms. The signal processing unit switches from a first one of the processing algorithms to a second one of the processing algorithms if a decision is made in the decision unit that one of the microphones is defective. In particular, if a microphone fails, automatic switching from directional microphone operation into omnidirectional operation is for example made possible.
