description The application relates to a hearing device comprising an input unit for providing first and second electric input signals ( I 1 , I 2 ) representing sound signals, a beamformer filter (BF) for making frequency-dependent directional filtering of the electric input signals ( I 1 , I 2 ), the output of said beamformer filter ( BF ) providing a resulting beamformed output signal ( RBFS ) . The application further relates to a method of providing a directional signal. The object of the present application is to create a directional signal. The problem is solved in that the beamformer filter ( BF ) comprises a directional unit (DIR) for providing respective first and second beamformed signals ( ID 1 , ID 2 ) from weighted combinations of the electric input signals ( I 1 , I 2 ), an equalization unit for equalizing a phase (and possibly an amplitude) of the beamformed signals ( ID 1 , ID 2 ) and providing first and second equalized beamformed signals ( IDE 1 , IDE 2 ), and a beamformer output unit ( BOU ) for providing the resulting beamformed output signal ( RBFS ) from the first and second equalized beamformed signals ( IDE 1 , IDE 2 ) . This has the advantage to create a directional signal where the phase of the individual components is preserved, and therefore introducing no phase distortions. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems, and combinations thereof.
