Patent ID: 8744102

Claim:
A hearing aid comprising: at least one microphone for converting input sound into an input signal; a subtraction node for subtracting a feedback cancellation signal from the input signal thereby generating a processor input signal; a hearing aid processor for producing a processor output signal by applying an amplification gain to the processor input signal; a receiver for converting the processor output signal into output sound; an adaptive feedback cancellation filter for adaptively deriving the feedback cancellation signal from the processor output signal by applying filter coefficients; calculation means for calculating an autocorrelation value of a reference signal; and an adaptation means for adjusting the filter coefficients with an adaptation rate, wherein the adaptation rate is set in dependency of the autocorrelation value calculated for the reference signal; wherein the adaptation means is adapted to decrease the adaptation rate when the autocorrelation value of the reference signal increases, and wherein the processor is adapted to decrease the amplification gain when the autocorrelation value of the reference signal increases.
