  • Hearing aid comprising a combined feedback and active noise cancellation system
    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.

  • HEARING DEVICE WITH ACTIVE NOISE CANCELLATION
    Publication number: 20250168572
    Abstract: Disclosed herein are embodiments of a method of operating a hearing aid with an active noise control system. The method can utilize an ambient sound detector for classification of an ambient sound environment, such as a coherence measure between audio signals. The method can further include mixing audio signals with a feed-forward compensating signal in dependence on the particular classification of the sound environment.
