Abstract
A hearing device, e.g. a hearing aid, comprises a) first and b) second input transducers located on the head, and at or in an ear canal of the user, respectively, and providing respective electric input signals, c) a signal processing unit comprising c1) a weighting unit for applying weights to the electric input signals, and c2) a hearing loss processing unit providing a processed signal. The hearing device further comprises d) an output unit to provide a stimulus perceivable by the user as sound, e) a feedback detection unit for providing a measure of the current level of feedback from the output to the input, and f) an input signal weight control unit configured to control or influence first and second weights applied to the first and second electric input signals in dependence of the measure of the current level of feedback, and a current level and frequency dependent target gain.
