Abstract: A method including operating an adaptive system of a hearing prosthesis, and determining one or more feedback path parameters of the hearing prosthesis based on the operation of the adaptive system of the hearing prosthesis, wherein the action of determining one or more feedback path parameters includes determining the one or more feedback path parameters based on data based on adaptive filter coefficients of adaptive filters of the adaptive system.

Abstract: Disclosed herein is a feedback reduction system for used in a hearing prosthesis. The hearing prosthesis will receive an input signal, process the input signal, and create a transformed output. However, the hearing prosthesis may suffer from feedback. Thus, a system to minimize the feedback in a hearing prosthesis may be desirable. One system to minimize the feedback includes down-sample circuitry configured to down-sample a first signal, creating a down-sampled signal. They system also includes a filter circuit. The filter circuit filters both the first signal and the down-sampled signal. The filter will output a filtered signal and a filtered down-sampled signal, respectively. Additionally, the system features up-sample circuitry that up-samples the filtered down-sampled signal. The output of the up-sample circuitry is an up-sampled signal. Further, the system features combining circuitry that creates a feedback-reduced signal based on the up-sampled signal, the filtered signal, and an input signal.

Abstract: Systems, methods, and devices are disclosed. An example sound processor is disclosed. The example sound processor includes a module configured to identify a feedback artifact in a current sample of an input spectral component by determining that a change in a signal level of an input spectral component is approximately equal to a predicted change. The predicted change may be based on one or more characteristics of an external feedback loop. Responsive to identifying the feedback artifact, the sound processor is further configured to apply a modification to a parameter used to process the input spectral component. The modification reduces a likelihood of including audible feedback in a processed input spectral component.
