发明名称 Hearing Instrument with Improved Initialisation of Parameters of Digital Feedback Suppression Circuitry
摘要 A method of modelling a feedback path from a receiver to a microphone in a hearing instrument, includes applying an electronic probe signal with an increasing level as a function of time to the receiver for conversion of the electronic probe signal into an acoustic probe signal output by the receiver, monitoring values of a first quality parameter calculated based at least in part on recorded microphone output signal, and after the first quality parameter reaches a predetermined first threshold value, determining at least one parameter of the feedback path based at least in part on the recorded microphone output signal values.
