  • Patent number: 11678127
    Abstract: A method operates a hearing system having a hearing device and modifies an input signal for the purpose of sound output to a user and, applies multiple algorithms with a respective potency, as a result of which a respective algorithm is applied with a present potency in a present situation. The hearing system recurrently receives a report from the user indicating that the user is dissatisfied with the sound output in the present situation. The hearing system has a database, containing multiple weights for each algorithm, to rate a change of the potency. If a report is received, each of the algorithms is rated using the weights to ascertain an individual-case relevance for each of the algorithms, to assess the effect of a change of the potency. Multiple individual-case relevances are combined to form a relevance value for each algorithm, the relevance values are compared with one another.

  • Patent number: 11070923
    Abstract: A method performs directional signal processing for a hearing aid. First and second input transducers of the hearing aid generate first and second input signals, respectively, from a sound signal. A first calibration directional signal which has a relative attenuation in the direction of a first useful signal source is generated from the first and second input signals, and a second calibration directional signal which has a relative attenuation in the direction of a second useful signal source is generated from the first and second input signals. A relative gain parameter is determined from the first and second calibration directional signals. First and second processing directional signals are generated from both the first and second input signals. A source-sensitive directional signal is generated from the first and second processing directional signals and the relative gain parameter. An output signal of the hearing aid is generated from the source-sensitive directional signal.

  • Patent number: 10873817
    Abstract: In a method that reduces the occurrence of acoustic feedback in a hearing device, a first wearing situation is created that determines a positioning of the hearing device relative to the wearer. For the first wearing situation, a first usage situation is created being a body movement of the wearer of the hearing device and/or a relative position of an external object relative to the body of the wearer. A first number of frequency-resolved curves of a feedback tendency of the hearing device are determined for the first use situation. A first criticality measure is ascertained based on the frequency-resolved curve for the first use situation that contains information on a frequency range that is critical with respect to an occurrence of acoustic feedback and a corresponding relative probability of acoustic feedback, and a target is established for adapting a hearing device parameter based on the first criticality measure.

  • Patent number: 10827287
    Abstract: In a method of operating a hearing device, an input transducer of the hearing device generates an input signal. A preliminary output signal is generated from this input signal through signal processing. An expected direct sound that is expected to be heard at one ear of a user of the hearing device is ascertained based on the input signal. A propagation delay of the preliminary output signal is ascertained with respect to the expected direct sound. A masking signal is generated based on the input signal and/or the preliminary output signal, taking into account the expected direct sound and/or the propagation delay of the preliminary output signal with respect to the expected direct sound. An output signal is generated based on the preliminary output signal and masking signal.

  • Patent number: 10805749
    Abstract: A method operates a hearing aid device, in particular a tinnitus treatment device. The hearing device has a microphone and a receiver, which can be inserted into an auditory canal of a user or is arranged at least in part in the auditory canal. Wherein active noise control of an acoustic environmental signal, which can be received by the microphone, is achieved at one or more tinnitus frequencies of a user by generating an acoustic cancellation signal from the receiver in the auditory canal of the user.

  • Patent number: 10652670
    Abstract: A method operates a hearing aid which has at least one input transducer and at least one output transducer. An input signal is generated by the at least one input transducer from a sound signal in the environment. From the input signal, a classification of a hearing situation of the environment is determined and/or at least one of four parameters including tonality, loudness, stationarity and reverberation time is determined for the sound signal of the environment. A first intermediate signal is generated in dependence on the input signal by signal processing. Wherein by the classification of the hearing situation and by at least one of the four parameters of tonality, loudness, stationarity and reverberation time, at least one parameter of a frequency distortion is predetermined. The frequency distortion predetermined in this way is applied to the first intermediate signal.

  • Patent number: 10257621
    Abstract: A method for operating a hearing system is defined, wherein a sound signal emanating from a sound source is measured by a plurality of microphones, which are fitted in different devices. Each of the microphones detects the sound signal and generates therefrom a microphone signal. The hearing system is binaural and two of the devices are each embodied as a hearing aid. For at least the two microphone signals from the microphones of the hearing aids there is determined an individual reverberation time in each case, and the individual reverberation times are combined in a dataset from which a general reverberation time is determined. An operating parameter of the hearing system is adjusted according to the general reverberation time. A corresponding hearing system is also defined.

  • Patent number: 9980056
    Abstract: A method for suppressing acoustic feedback in a hearing aid device and a corresponding device and a system. A frequency range to be transmitted by the hearing aid device is divided into two frequency ranges that are separated by a split-band frequency. A transfer function of a feedback path is estimated in a frequency range and assessed for its behavior at the split-band frequency. Depending on the result of the assessment, the split-band frequency is lowered or raised and in the upper frequency range a phase and/or frequency change is applied for suppressing feedback.
