Abstract
The application relates to a hearing aid comprising a forward path comprising a) a multitude of input units for providing a multitude of electric input signals IN, i=1, . . . , M, representative of sound, b) a multi input beam former filtering unit for providing a beam formed signal Yfrom said multitude of electric input signals, c) a gain unit for applying a hearing aid gain Gto said beam formed signal Y, and providing a processed signal, and d) an output unit for providing stimuli perceivable by a user as sound based on said processed signal or a signal derived therefrom. The hearing aid further comprises e) a gain control unit for limiting said hearing aid gain Gto a modified full-on gain value G'. The multi input beam former filtering unit is configured to apply a current frequency dependent directional gain Gto each of said multitude of electric input signals IN, and the gain control unit is configured to determine the modified full-on gain value G′in dependence of said current directional gains G, i=1, . . . , M, and a previously determined full-on gain value G. Thereby an improved hearing aid is provided. The invention may e.g. be used for hearing instruments, headsets, or active ear protection systems.
