Hearing Instrument with Improved Initialisation of Parameters of Digital Feedback Suppression Circuitry

A hearing instrument comprising:

• a microphone for converting incoming sound into a microphone audio signal;
• a Digital Feedback Suppression Circuit for modelling a feedback path of the hearing instrument;
• a signal processor for processing the audio signal;
• a receiver connected to an output of the signal processor for converting the processed audio signal into a sound signal;
• and
• a probe signal generator controlled by the signal processor for providing a probe signal to the receiver, wherein the receiver is configured for converting the probe signal into an acoustic probe signal output;
• wherein the signal processor is configured for (1) recording the microphone audio signal, (2) controlling the probe signal generator for increasing a level of the probe signal, (3) monitoring values of a first quality parameter calculated based at least in part on the recorded audio signal;
• and (4) determining at least one parameter of the feedback path based at least in part on the recorded audio signal after the first quality parameter has reached a predetermined first threshold value.
