Abstract

Die Erfindung gibt ein Hörgerät (30) mit einem adaptiven Richtmikrofon (33) zur Rückkopplungsunterdrückung und ein zugehöriges Verfahren an. Das Hörgerät (30) weist eine Adaptionseinheit (32) auf, die das Richtmikrofon (33) so einstellt, dass ein von einem Hörer (37) des Hörgeräts (30) zum Richtmikrofon (33) rückgekoppeltes Schallsignal gedämpft wird. Die Erfindung bietet den Vorteil, dass Artefakt-frei auf einfache Weise eine akustische Rückkopplung gedämpft bzw. unterdrückt wird.

The invention provides a hearing aid (30) with an adaptive directional microphone (33) for feedback suppression and an associated method. The hearing device (30) has an adaptation unit (32) which adjusts the directional microphone (33) so that a sound signal fed back from a listener (37) of the hearing device (30) to the directional microphone (33) is attenuated. The invention has the advantage that artifact-free in a simple way, an acoustic feedback is damped or suppressed.
