Abstract
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.
Claims8
A method for operating a hearing apparatus, which comprises the steps of:
- splitting an input signal of the hearing apparatus into a low-frequency signal component and a high-frequency signal component via a frequency separating filter;
- and
- setting a predefinable threshold frequency of the frequency separating filter by analyzing the input signal so that artifacts in an output signal of the hearing apparatus are reduced, the predefinable threshold frequency being determined by analyzing one of a signal level or a tonality of the input signal.
A hearing apparatus, comprising:
- a frequency separating filter characterized by a threshold frequency and splits an input signal into a low-frequency signal component and a high-frequency signal component;
- and
- a first means for setting the threshold frequency based on an analysis of the input signal so that artifacts in an output signal of the hearing apparatus are reduced, said first means being coupled to said frequency separating filter, said first means determining the threshold frequency by analyzing one of a signal level or a tonality of the input signal.
