Abstract
A hearing aid includes: a cue filter having an input that is provided with an output from the BTE sound input transducer; an adaptive feedback canceller configured to provide an output modelling a feedback path between the output transducer and the BTE sound input transducer, wherein the output modelling the feedback path is provided to a subtractor for subtraction of the output modelling the feedback path from the output of the BTE sound input transducer to obtain a difference, the subtractor outputting the difference to the cue filter; and a feedback and cue controller connected to the adaptive feedback canceller and the cue filter, wherein the feedback and cue controller is configured to control the cue filter to reduce a difference between an output of the ITE microphone and a combined output that is obtained using at least the cue filter.
