Abstract
A method for enhancing a signal directionality in a hearing instrument wherein first and second signals are generated by first and second input transducers that are spaced apart from one another. A first directional signal is derived from the first input signal and the second input signal by applying a second-to-first relative transfer function with respect to a first target angle to the second input signal. The second-to-first relative transfer function is a relative transfer function from the second input transducer to the first input transducer with respect to the first target angle. Similarly, a second directional signal is derived from the second input signal and the first input signal by applying a first-to-second relative transfer function with respect to a second target angle to the first input signal. An angle-enhanced signal is derived from the first directional signal and the second directional signal.
