摘要： A hearing device has an acceleration sensor that is positioned on the head of a hearing device wearer in the intended worn state, is configured for measurement in two mutually orthogonal measurement axes and is operated by virtue of at least one main feature related to an acceleration directed tangentially in relation to the head being derived from an acceleration signal of the acceleration sensor. The at least one main feature is used to ascertain a presence of a yaw movement of the head by taking into consideration at least one prescribed criterion, derivable from the acceleration signal itself, beyond the presence of an acceleration value of the tangentially directed acceleration that is indicative of a movement.

摘要： A method distorts the frequency of an input signal that is present as an audio signal. Here, the input signal is divided into a low-frequency signal component and a high-frequency signal component. These two signal components adjoin one another at a cut-off frequency. The high-frequency signal component is frequency-distorted and overlaid with the low-frequency signal component to form an output signal. An associated gain factor is modified, at least for an edge region, containing the cut-off frequency, of the high-frequency signal component and/or of the low-frequency signal component, such that a level difference between a signal level of the low-frequency signal component and a signal level of the frequency-distorted high-frequency signal component is increased.

摘要： A method for suppressing interference noise in an acoustic system with a microphone that generates an input signal and a loudspeaker that generates an acoustic signal which partially feeds back to the microphone. A first intermediate signal is formed along a primary signal path as a function of the input signal, and an output signal is formed via a frequency distortion. The output signal is coupled into a signal feedback path. A second intermediate signal is formed in the signal feedback path via a decorrelation and used as an input value for an adaptive filter. The adaptive filter generates a compensation signal which compensates the input signal. A third intermediate signal is formed from the input signal and/or compensated input signal, which is used as an input value for the adaptive filter. The output signal is fed to the loudspeaker for reproduction.

摘要： A method operates a binaural hearing aid system with first and second hearing aids. A first audio signal of the first hearing aid is divided into a first high-frequency component and a first low-frequency component. A second audio signal of the second hearing aid is divided into a second high-frequency component and a second low-frequency component. A first provisional division frequency is specified for the division of the first audio signal into the first high-frequency component and the first low-frequency component. A second provisional division frequency is specified for the division of the second audio signal into the second high-frequency component and the second low-frequency component. A division frequency is defined on the basis of the first provisional division frequency and the second provisional division frequency. The first and second audio signals are divided at the division frequency into respective high-frequency components and low-frequency components.

摘要： A method performs frequency distortion of an audio signal. The audio signal is divided at at least one division frequency into a low-frequency band and a high-frequency band. A frequency-distorted signal is generated through respectively different distortions of frequencies for the high-frequency band and for the low-frequency band. The division frequency is selected such that it is located between two neighboring tones of a given tonal system.

摘要： A method for detecting a defect in a hearing instrument that has at least one first input transducer and at least one output transducer. A first transfer function of a first acoustic system, which includes the output transducer and the first input transducer, is determined, and at least a first reference function for the first transfer function is determined. The first transfer function is compared with the first reference function and a defect in the hearing instrument is detected based on the comparison. A hearing instrument with an input transducer and an output transducer is set up to carry out the method.

摘要： A method for the frequency distortion of an audio signal includes splitting the audio signal into a plurality of specified frequency bands, in which a band limit frequency is defined in each case by two respective immediately adjacent frequency bands. A first frequency band and a second frequency band lying immediately above the first frequency band are determined on the basis of the audio signal. A distortion of the frequencies differing from the distortion applied to signal components in the second frequency band is applied to signal components in the first frequency band, and a frequency-distorted signal is generated as a result. A method for suppressing an acoustic feedback in an acoustic system and a hearing aid are also provided.

摘要： 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.

摘要： A method for operating a hearing apparatus system with at least one hearing apparatus uses a first sensor of the hearing apparatus to capture a first measured variable characteristic of an actual wearing situation. If the first measured variable and/or a variation over time derived therefrom satisfies at least one prescribed first criterion, it is inferred that the hearing apparatus has had a tumble. If the tumble is detected to have taken place, at least one further measured variable and/or a variation over time derived therefrom is captured, and the at least one further measured variable is used to ascertain whether the hearing apparatus is arranged on the head of a hearing device wearer after the tumble.
