Abstract

The invention relates to a hearing aid with a controllable directional characteristic, having at least two spaced apart first and second microphones (Fmic, Bmic), at least one signal processing unit, at least one output transducer and a directional controller including at least one delay device for delaying the output signal from at least the second of said at least two microphones to be combined with the undelayed output signal from at least one other microphone, the directional controller comprising adding or combination means (4, 5, 6) and at least a first attenuator means (1) for processing the output signal of said second microphone (Bmic), generating a first processed signal to be added by said adding means (5, 6) to the output signal of said first microphone (Fmic), further comprising at least a second attenuator means (2) to operate on the output signal of said first microphone (Fmic) for generating a second processed signal to be combined with the output signal of said first microphone (Fmic) by said adding means (4, 5, 6) wherein the directional controller comprises at least a delay device (3) inserted into the signal path of the second processed signal before it is added in the adding means (5, 6).
