  • Patent number: 12581248
    Abstract: A hearing aid comprises a forward path comprising a) an input transducer for converting sound (x(n), v(n)) in an environment around the hearing aid to an electric input signal (y(n)) representing said sound; b) a hearing aid processor for processing said electric input signal (y(n)), or a signal originating therefrom (e(n)), and to provide a processed signal (u(n)) based thereon; c) an output transducer for converting said processed signal (u(n)), or a signal originating therefrom (ua(n)), to acoustic stimuli presented to said eardrum of the user. The hearing aid further comprises d) a feedback control system for attenuating or cancelling feedback propagated via a feedback path (H) from an electric input signal to said output transducer to an electric output from said input transducer.

  • Patent number: 12556869
    Abstract: A hearing aid includes an input unit, an output unit, a signal processing unit connected to said input unit and output unit, where the input unit, the signal processing unit and the output unit are forming part of a forward path of the hearing aid, where the signal processing unit is configured to apply a forward gain to the at least one electric input signal or a signal originating therefrom. The hearing aid further includes a feedback control unit configured to reduce a risk of howl due to acoustic, electrical, and/or mechanical feedback of an external feedback path from the output unit to the input unit of said hearing aid, where the hearing aid is configured to receive motion data characterising movement and/or acceleration and/or orientation and/or position of the hearing aid to control processing.

  • Patent number: 12532130
    Abstract: A hearing aid comprises a multitude M?2 microphones adapted for providing M electric input signals (x) representative of an environment of a user, at least one beamformer for generating at least one beamformed signal in dependence of beamformer weights (w) configured to be applied to said electric input signals, thereby providing said at least one beamformed signal (Y) as a weighted sum of the M of electric input signals. The beamformer weights (w) are adaptively optimized to a plurality of target positions (?) by maximizing a target signal to noise ratio (SNR) for sound from the target positions (?).

  • Publication number: 20250338071
    Abstract: Disclosed herein are embodiments of a hearing aid configured to be worn by a user. The hearing aid can include a user interface allowing the user to control functionality of the hearing aid, and a feedback sensor for repeatedly providing a feedback signal indicative of a current estimate of feedback from an output transducer to an input transducer of the hearing aid, wherein the user interface is based on changes to the current estimate of the feedback path, e.g. provided by the user.

  • Publication number: 20240430624
    Abstract: A hearing aid including a multitude M?2 microphones adapted for providing M electric input signals (x) representative of an environment of a user, at least one beamformer for generating at least one beamformed signal in dependence of beamformer weights (w) configured to be applied to said electric input signals, thereby providing said at least one beamformed signal (Y) as a weighted sum of the M of electric input signals.
