摘要：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 directionalcontroller including at least one delay device for delaying the output signal from at leastthe second of said at least two microphones to be combined with the undelayed outputsignal from at least one other microphone, the directional controller comprising addingor combination means (4, 5, 6) and at least a first attenuator means (1) for processing theoutput signal of said second microphone (Bmic), generating a first processed signal to beadded 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 outputsignal of said first microphone (Fmic) for generating a second processed signal to becombined 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).
