  • Patent number: 10987031
    Abstract: A method of performing real ear measurements by a measuring system is described herein. The measuring system comprises a probe element adapted to be inserted in the ear canal of an individual; a loudspeaker configured to deliver a sample sound signal to the ear canal; at least one microphone configured to detect a response to the sample sound signal, wherein the probe element is in acoustic communication with the loudspeaker and cooperates with the at least one microphone; and a signal processing unit for performing an acoustic measurement of a response to the sample sound signal, based on an electrical input signal from the microphone.
    Type: Grant

  • Patent number: 9942674
    Abstract: A method for operating a hearing device for a user having tinnitus includes converting an acoustic input signal into a corresponding converted input signal, applying a transfer function to the converted input signal for generating a processed input signal, generating a stimulation signal depending on characteristics of a perceived disturbing internal signal resulting from a tinnitus perceived by a prospective user of the hearing device, limiting the stimulation signal by applying a predefined limiting scheme thereby generating a limited stimulation signal, superimposing the limited stimulation signal onto the processed signal thereby generating an output signal, and feeding the output signal to an output transducer for generating a hearing device output signal.

  • Patent number: 8582793
    Abstract: A method for determining feedback thresholds in a plurality of frequency bands and/or at a plurality of frequencies processed by a hearing device is disclosed. The feedback thresholds are defined as gains, at which feedback occurs while a hearing device user is wearing the hearing device. The method comprises the step of determining feedback thresholds in an order of precedence, wherein the order of precedence being defined according to a degree of importance that the feedback threshold is determined in a particular frequency band or at a particular frequency, respectively.

  • Publication number: 20110026746
    Abstract: A method for determining feedback thresholds in a plurality of frequency bands and/or at a plurality of frequencies processed by a hearing device is disclosed. The feedback thresholds are defined as gains, at which feedback occurs while a hearing device user is wearing the hearing device. The method comprises the steps of determining a quality index for a measured feedback threshold, and considering a measured feedback threshold as final if the quality index meets minimum predefined requirements.
