Abstract: A method for operating a hearing aid system. The hearing aid system includes a hearing aid with at least one input transducer, an output transducer, and a motion sensor. The movement of a hearing aid system user is captured as movement data of the motion sensor. A probability for a future fall or trip event on the part of the hearing aid system user is determined on the basis of the captured movement data. A perceptible warning signal is generated when the probability reaches or exceeds a stored threshold value.

Abstract: A method reduces echo in a hearing instrument. A first input transducer generates a first input signal from ambient sound. A communication unit receives an external input signal from an external device. The first input signal and the external input signal are used to generate an output signal. The output signal is used in a first filter to generate a compensation signal for reducing echo and/or acoustic feedback. The first input signal and the compensation signal are used to generate an error signal. Filter coefficients of the first filter and/or a comparison of the error signal with the compensation signal and/or with the first input signal are/is used to generate a control variable. The control variable is taken as a basis for applying a second filter for rejecting a residual echo or a residual feedback to an intermediate signal derived from the input signal, and a transmission signal is generated.

Abstract: A binaural hearing system for assisting a hearing of a user includes two hearing instruments each to be worn in or on an ear of the user. An audio signal is modified in each of the two hearing instruments by way of a programmable signal processor of the respective hearing instrument by executing a plurality of software modules of firmware of the hearing system and is output by an output transducer of the respective hearing instrument. The executed software modules of the firmware are distributed asymmetrically on the two hearing instruments, so that at least one of the software modules of the firmware is selectively executed in one of the two hearing instruments.

Abstract: A hearing device has an acceleration sensor that measure along three mutually perpendicular measurement axis. A movement of the hearing aid wearer is deduced from acceleration data of the acceleration sensor issued in an acceleration signal, a movement plane of the movement of the hearing aid wearer is derived from the acceleration data, a movement axis and a movement direction of the movement are ascertained from the acceleration data, and the presence of a rotational movement of the head is deduced on the basis of the movement plane, the movement axis and the movement direction. A direction of view probability distribution is created from the detected rotational movements, in particular on the basis of a yaw angle ascertained in the process. The direction of view probability distribution specifies a probability that the actual direction of view of the hearing aid wearer extends along an assigned angle.

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.

Abstract: 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.

Abstract: 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.

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.

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.

Abstract: 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.

Abstract: A method and an apparatus reduce feedback in a hearing aid device. The method includes the step of acquiring a first feedback transfer function at a first point in time on a feedback path from a signal processing device via an electro-acoustic transducer, an acoustic signal path from the electro-acoustic transducer to an acousto-electric transducer and via the acousto-electric transducer back to the signal processing device. In a further step, a weighted mean value function is determined in a manner dependent on amplitude absolute values of the first feedback transfer function. A second feedback transfer function is estimated by an adaptive filter, wherein coefficients of the adaptive filter are determined in a manner dependent on the weighted mean value function. The adaptive filter is applied to a signal which is derived from an acoustic input signal of the acousto-electric transducer.

Abstract: A method suppresses feedback in a hearing instrument. A microphone generates an input signal and a loudspeaker generates an acoustic signal which is partially fed back to the microphone via an acoustic feedback path. An intermediate signal is generated along a main signal path depending on the input signal, and an output signal is formed on the basis of the intermediate signal. A voice activity of a user is monitored, a transfer function of an electro-acoustic closed signal loop formed by the main signal path and the feedback path is estimated, that, depending on the transfer function of the closed signal loop and the voice activity of the user, the intermediate signal is decorrelated to form the output signal. A compensation signal is generated from the output signal and is fed to the input signal for feedback compensation, and the output signal is fed to the loudspeaker for reproduction.
