Abstract (en)
[origin: US2016080875A1] A method and apparatus reduce feedback in a hearing aid. The method involves a first transfer function, which includes a feedback path, being estimated for a first section of a signal response. A power of a feedback signal from a second transfer function of the feedback path is estimated for a second section of the signal response, and a parameter of the signal processing device and/or of the feedback suppression unit is adjusted on the basis of the estimated power.
