Abstract
The disclosure relates to a method of optimizing audio processing in a hearing device configured to be worn at an ear of a user, the method comprising receiving an input audio signal; processing the input audio signal by a plurality of audio processing algorithms executed in a sequence and/or in parallel to generate a processed audio signal; and outputting, by an output transducer included in the hearing device, an output audio signal based on the processed audio signal so as to stimulate the user's hearing.
Claims19
A method of optimizing audio processing in a hearing device configured to be worn at an ear of a user, the method comprising:
- receiving an input audio signal;
- processing the input audio signal by a plurality of audio processing algorithms executed in a sequence and/or in parallel to generate a processed audio signal;
- and
- outputting, by an output transducer included in the hearing device, an output audio signal based on the processed audio signal so as to stimulate the user's hearing;
- characterized by
- comparing the input audio signal and the processed audio signal to determine at least one deviation characteristic indicative of a deviation of the processed audio signal from the input audio signal;
- selecting, depending on the deviation characteristic, at least one of the audio processing algorithms;
- controlling the selected audio processing algorithm to adjust the processing of the input audio signal;
- providing an expectation measure indicative of an expected deviation of the processed audio signal from the input audio signal corresponding to a desired outcome of said processing of the input audio signal;
- and
- determining whether said deviation characteristic matches the expectation measure,
- wherein said selecting of the audio processing algorithm and said controlling of the selected audio processing algorithm are performed in a case in which a mismatch between said deviation characteristic and the expectation measure has been determined.

- evaluating, before said comparing of the input audio signal and the processed audio signal, the processed audio signal with regard to said spatial and/or binaural cues;
- and
- determining, from said evaluating of the input audio signal and the processed audio signal with regard to said spatial and/or binaural cues, said at least one deviation characteristic.
