A method for operating a hearing device on the basis of a speech signal. An acousto-electric input transducer of the hearing device records a sound containing the speech signal from surroundings of the hearing device and converts the sound into an input audio signal. A signal processing operation generates an output audio signal based on the input audio signal. At least one articulatory and/or prosodic feature of the speech signal is quantitatively acquired through analysis of the input audio signal by way of the signal processing operation, and a quantitative measure of a speech quality of the speech signal is derived on the basis of the property. At least one parameter of the signal processing operation for generating the output audio signal based on the input audio signal is set on the basis of the quantitative measure of the speech quality of the speech signal.

Method for operating a hearing device based on a speech signal, and hearing device

A hearing device includes at least one microphone configured to capture sound signals within an overall frequency range and to convert them into an input signal. A signal processor is provided for processing the input signal within a lower frequency range that is part of an overall frequency range. A detector is provided for detecting a noise that has frequency components both inside and outside the lower frequency range, namely in an upper frequency range above the lower frequency range. The hearing device is configured in such a way that the detector detects the noise based on its frequency component in the upper frequency range. A method for operating a hearing device is also provided.

Hearing device and method for operating a hearing device

A hearing system assists the hearing of a user and has a hearing instrument worn in or on the ear of the user. In operation, a sound signal from surroundings of the hearing instrument is received by an input transducer and modified in a signal processing step. The modified sound signal is output by an output transducer. A first signal component and a second signal component are derived from the received sound signal, wherein these signal components chronologically overlap. In the first signal component, the ego voice of the user is emphasized over the ambient noise, while in the second signal component, the ambient noise is emphasized over the ego voice of the user. The first signal component and the second signal component are processed in different ways in the signal processing step and combined after this processing to generate the modified sound signal.

Hearing system having at least one hearing instrument worn in or on the ear of the user and method for operating such a hearing system

A method operates a hearing aid system in which a dynamic range scheme for an automatic gain control is modified depending on the situation. A gain factor is set by the automatic gain control which has a dynamic range processor operated with a dynamic range scheme defining the gain factor in dependence on a level of an input signal. A corresponding hearing aid system carries out this method.

Method for operating a hearing aid system, and hearing aid system

A method operates a hearing aid where the hearing aid generates an input signal from acoustic signals from the environment. The hearing aid has a signal processor which is configured to modify the input signal and thereby generate an output signal. The signal processor has an automatic gain control for modifying the input signal, and has a compressor that can be operated with a compression scheme. The environment is divided into a plurality of directions of which one is selected by a direction determination unit as a relevant direction. The input signal is modified in a direction-dependent manner by the compressor being operated with a compression scheme, which is set dependent on the relevant direction, so that acoustic signals from the relevant direction are emphasized compared to acoustic signals from other directions.

Method for operating a hearing aid, and hearing aid

A method operates a hearing device where a first directional signal and a second directional signal are generated in the hearing device from a sound signal of the environment. A parameter is determined based on the first directional signal and the second directional signal, which represents a quantitative measure of the stationarity of a sound signal. A noise-optimized signal is generated from the first directional signal and the second directional signal based on the parameter. The method is performed by a hearing device having a first microphone and a second microphone for generating a first directional signal and a second directional signal. The hearing device is configured to implement the corresponding method.

Method of operating a hearing device and a hearing device

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.
