  • Publication number: 20150189451
    Abstract: A binaural hearing aid system includes: a first hearing aid having a first microphone, a first processing unit, a first receiver, and a first communication unit; and a second hearing aid having a second microphone, a second processing unit, a second receiver, and a second communication unit; wherein the first communication unit of the first hearing aid is configured to transmit a filtered signal for reception by the second communication unit of the second hearing aid in response to a signal associated with a phone.

  • Publication number: 20150125015
    Abstract: A hearing aid includes: an input transducer for generating an audio signal; a feedback suppression circuit configured for modelling a feedback path of the hearing aid; a subtractor for subtracting an output signal of the feedback suppression circuit from the audio signal to form a feedback compensated audio signal; a signal processor that is coupled to an output of the subtractor for processing the feedback compensated audio signal to perform hearing loss compensation; and a receiver that is coupled to an output of the signal processor for converting the processed feedback compensated audio signal into a sound signal; wherein the hearing aid further comprises a gain processor for performing gain adjustment of the feedback compensated audio signal based at least on an estimate of a residual feedback signal of the feedback compensated audio signal, wherein the estimate of the residual feedback signal is based at least on the audio signal.

  • Publication number: 20110103613
    Abstract: An audio system includes a signal processor for processing an audio signal, and a feedback suppressor circuit configured for modelling a feedback signal path of the audio system by provision of a feedback compensation signal based on sets of feedback model parameters for the feedback signal path that are stored in a repository.

  • Publication number: 20100177917
    Abstract: A hearing aid includes a signal processor, a input transducer electrically connected to the signal processor, a receiver electrically connected to the signal processor, an adaptive feedback cancellation filter configured to suppress feedback from a signal path between the receiver and the input transducer, and a feedback gain correction unit configured for adjusting a gain parameter of the signal processor based at least in part on coefficients of the adaptive feedback cancellation filter. A method of adjusting a gain parameter of a signal processor of a hearing aid includes monitoring filter coefficients of a feedback cancellation filter of the hearing aid, and adjusting the gain parameter of the signal processor in dependence of the monitored filter coefficients.
