In this paper, solutions for combined feedback and noise sup pression in hearing aids are developed. The techniques presented are based on the generalized sidel obe canceller (GSC) and adaptive feedback canceller (AFC), with a prediction error method (PEM) adapt ation to avoid speech distortion. Two possible cascades of GSC-based noise reduction and AFC, nam ely n ‘AFC first’ and a ‘GSC first’, as well as a truly integrated solution that jointly suppresses feedback and noise are discussed.
