摘要： A method operates a hearing apparatus. The hearing apparatus contains a frequency separating filter characterized by a threshold frequency, which splits an input signal into a low-frequency signal component and a high-frequency signal component. The hearing apparatus further has a first device, which can be used to set the threshold frequency of the frequency separating filter so that artifacts in an output signal of the hearing apparatus are reduced.

摘要： Switching a hearing device from a first operating state into a second operating state is to be configured in an acoustically-friendly fashion. A first output signal power of a first audio data stream is determined for the first operating state and a second output signal power of a second audio data stream is determined for the second d operating state. Furthermore, a fading function, which represents the overall output power during a fading process, and the initial value of which corresponds to the first output signal power and the end value of which corresponds to the second output signal power, is defined. The fading process is finally implemented by mixing the audio data streams such that the overall output power corresponds to the fading function or a corresponding approximation function. Volume jumps can thus be avoided to a large degree during a switchover between operating states.

摘要： A method for the operation of a hearing device with at least one receiver includes carrying out a fixed second frequency shift of an electrical receiver signal supplying the receiver or of a predefinable frequency range of the receiver signal and a variable first frequency shift of the receiver signal or of a predefinable frequency range of the receiver signal. The first frequency shift is changed depending on the occurring feedback. A frequency shift which effectively prevents feedback is advantageously carried out, while artifacts of the frequency shift are minimized.

摘要： A hearing aid is enabled for dynamic compression in a way to further improve the perception of acoustic signals in the provision of hearing assistance to a hearing-impaired person. Here, an input signal is divided into a plurality of frequency bands. Input-level-controlled dynamic compression is performed in at least one first frequency band and output-level-controlled dynamic compression is performed in at least one second frequency band. This optimizes both loudness perception and speech intelligibility.

摘要： A hearing device has a signal-processing apparatus for processing an input signal into an output signal, and a feedback-canceller apparatus for reducing feedback artifacts on the basis of the input signal and the output signal. The feedback-canceller apparatus has an adaptive, first filter, for establishing a set of filter coefficients for a predefined feedback situation. The feedback-canceller apparatus is configured to store the set of filter coefficients. It has at least one second filter, which can be operated directly parallel to the first filter on the basis of the stored set of filter coefficients. The adaptive, first filter can be continuously adapted to a current feedback situation, and the feedback-canceller apparatus is configured such that in the current feedback situation it automatically selects either the first or the second filter. As a result, it generally only requires a simple switchover, but not a complete adaptation.

摘要： Feedback in a hearing device and, more particularly, in a hearing aid should be compensated for before it becomes audible. To this end, a method is proposed for compensating for a feedback signal in a hearing device with an input-transducer apparatus, a signal-processing apparatus and an output-transducer apparatus, in which method a feedback signal is compensated for, which feedback signal is fed back to the input-transducer apparatus from the output-transducer apparatus or the signal-processing apparatus. More particularly, a probability of having a plurality of notches, equally spaced apart from one another, in the spectrum of an input signal is established, which input signal originates directly from the input-transducer apparatus or which is a difference signal between the signal directly from the input-transducer apparatus and a compensation signal serving for compensation. The compensation is modified or the signal-processing apparatus is amplified as a function of this established probability.
