Abstract

A hearing device, e.g. a hearing aid, comprises a) a multitude of input transducers for providing respective electric input signals representing sound in an environment of the user; b) an output transducer for providing stimuli perceivable to the user as sound based on said electric input signals or a processed version thereof; c) an adaptive beamformer filtering unit connected to said input unit and to said output unit, and configured to provide a spatially filtered signal based on said multitude of electric input signals and adaptively updated beamformer weights; and d) a feedback estimation unit providing feedback estimates of current feedback paths from said output transducer to each of said input transducers. The hearing device is configured to provide that at least one of said adaptively updated beamformer weights of the adaptive beamformer filtering unit is/are updated in dependence of said feedback path estimates. The application further relates to a method of suppressing feedback.
