Abstract
A system for reducing noise in a drive signal of a hearing device, including a microphone operative to receive sound and generate a microphone output signal and an adaptive filter apparatus that receives a signal from a transducer separate from the microphone and outputs a filtered signal, wherein the system subtracts the outputted filtered signal from a signal based on the microphone output signal to cancel noise and outputs the resulting signal, and the system further processes the resulting signal to obtain a further processed resulting signal to remove and/or eliminate residual feedback present in the resulting signal.
