Abstract
A method suppresses feedback in a hearing instrument. A microphone generates an input signal and a loudspeaker generates an acoustic signal which is partially fed back to the microphone via an acoustic feedback path. An intermediate signal is generated along a main signal path depending on the input signal, and an output signal is formed on the basis of the intermediate signal. A voice activity of a user is monitored, a transfer function of an electro-acoustic closed signal loop formed by the main signal path and the feedback path is estimated, that, depending on the transfer function of the closed signal loop and the voice activity of the user, the intermediate signal is decorrelated to form the output signal. A compensation signal is generated from the output signal and is fed to the input signal for feedback compensation, and the output signal is fed to the loudspeaker for reproduction.
