Abstract
A method performs directional signal processing for a hearing aid. First and second input transducers of the hearing aid generate first and second input signals, respectively, from a sound signal. A first calibration directional signal which has a relative attenuation in the direction of a first useful signal source is generated from the first and second input signals, and a second calibration directional signal which has a relative attenuation in the direction of a second useful signal source is generated from the first and second input signals. A relative gain parameter is determined from the first and second calibration directional signals. First and second processing directional signals are generated from both the first and second input signals. A source-sensitive directional signal is generated from the first and second processing directional signals and the relative gain parameter. An output signal of the hearing aid is generated from the source-sensitive directional signal.
