Abstract
A system for hearing assistance includes one or more microphones, a speaker and processing circuitry. The one or more microphones are configured to be mounted in proximity to a head of a subject and to output electrical signals in response to acoustic waves that are incident on the microphones. The speaker is configured for mounting in proximity to an ear of the subject. The processing circuitry is configured to amplify and filter the electrical signals so as to generate a drive signal for input to the speaker using a digital filter having multiple taps with respective tap coefficients selected to suppress feedback from the speaker to the microphones, and to compute the tap coefficients adaptively while estimating respective coherence values of the tap coefficients over time and weighting updates applied to the tap coefficients responsively to the respective coherence values.
