A hearing aid comprises a forward path comprising a) an input transducer for converting sound (x(n), v(n)) in an environment around the hearing aid to an electric input signal (y(n)) representing said sound; b) a hearing aid processor for processing said electric input signal (y(n)), or a signal originating therefrom (e(n)), and to provide a processed signal (u(n)) based thereon; c) an output transducer for converting said processed signal (u(n)), or a signal originating therefrom (ua(n)), to acoustic stimuli presented to said eardrum of the user. The hearing aid further comprises d) a feedback control system for attenuating or cancelling feedback propagated via a feedback path (H) from an electric input signal to said output transducer to an electric output from said input transducer.
