Abstract: Due to the problem of lack of reliability in the available methods, a new solution is constructed for acoustic feedback control using single channel blind source separation. The main advantage of this solution is that the result has nothing to do with the feedback path so that it has high reliability. Computer simulations are given to demonstrate the performance of this method.
