Abstract
A hearing aid includes a microphone for converting sound into an audio input signal, a hearing loss processor, an adaptive feedback suppressor configured for generation of a feedback suppression signal by modelling a feedback signal path of the hearing aid, a subtractor coupled to an output of the adaptive feedback suppressor, wherein the subtractor is configured for subtracting the feedback suppression signal from the audio input signal, and outputting a feedback compensated audio signal to the hearing loss processor, and wherein the hearing loss processor is configured for processing the feedback compensated audio signal in accordance with a hearing loss of a user of the hearing aid, a synthesizer configured for generation of a synthesized signal based at least on a sound model and the audio input signal, and a receiver for generating an output sound signal based at least on the synthesized signal.
