Abstract
The disclosure relates to a method of operating a hearing device configured be worn at an ear of a user, the method comprising receiving an audio signal; processing the audio signal by at least one audio processing algorithm 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. The disclosure further relates to a hearing device configured to perform the method.
Claims15
A method of operating a hearing device configured to be worn at an ear of a user, the method comprising:
- receiving an audio signal;
- processing the audio signal by at least one audio processing algorithm to generate a processed audio signal;
- 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;
- providing different audio processing algorithms each configured to be applied on the audio signal and associated with a performance index indicative of a performance of the audio processing algorithm when applied on the audio signal, wherein the performance index is pre-determined for each audio processing algorithm prior to the processing of the audio signal;
- determining a target index relative to the performance index, the target index indicative of a target performance of said processing of the audio signal;
- selecting, depending on the target index, at least one of the processing algorithms;
- and
- applying the selected processing algorithm on the audio signal.
A hearing device configured to be worn at an ear of a user, the hearing device comprising:
- an input transducer configured to provide an audio signal indicative of a sound detected in an environment of the user;
- a processor configured to process the audio signal by at least one audio processing algorithm to generate a processed audio signal;
- and
- an output transducer configured to output an output audio signal based on the processed audio signal so as to stimulate the user's hearing,
- wherein the processor is further configured to:
- provide different audio processing algorithms each configured to be applied on the audio signal and associated with a performance index indicative of a performance of the audio processing algorithm when applied on the audio signal, wherein the performance index is pre-determined for each audio processing algorithm prior to the processing of the audio signal;
- determine a target index relative to the performance index, the target index indicative of a target performance of said processing of the audio signal;
- select, depending on the target index, at least one of the processing algorithms;
- and
- apply the selected processing algorithm on the audio signal.
