A method performs directional signal processing for a hearing instrument. First and second input signals are generated by first and second input transducers, respectively, from a sound signal. The first front intermediate signal and a first rear intermediate signal are each formed from the first and second input signals. A first superposition of the first front intermediate signal and the first rear intermediate signal is formed by a complex-value first superposition parameter and is adapted based on the first superposition parameter. A complex value of the first superposition parameter resulting from the adaptation of the first superposition is converted into a first alternative parameter and a second alternative parameter. An output signal is generated based on the first alternative parameter, the limited second alternative parameter and a superposition of the first and second input signals.

Method for directional signal processing for a hearing instrument

A hearing aid has at least two input transducers and at least one output transducer. The input transducers generate an input signal from a sound signal from the surroundings. At least two directional signals with different directional characteristics are formed from the input signals and the directional signals are examined for the presence of a useful signal. A first weighting factor is assigned to the directional signal with the largest signal component of the useful signal and a second weighting factor is assigned to the other directional signals. The directional signals are multiplied by the respectively assigned weighting factor, and an output signal is then formed from the multiplication result. The output signal is converted into a sound signal by the output transducer.
