Abstract (en)

A method of processing an audio signal, comprising: at an ipsilateral hearing device (100) with a first input unit (110) including one or more microphones (112,113) and configured to generate a first directional input signal (F<sub>L</sub>); a communications unit (120) configured to receive a second directional input signal (F<sub>R</sub>) from a contralateral hearing device; an output unit (140); and a processor (130) coupled to the first input unit (110), the communications unit (120) and the output unit (140); determining one or both of a first gain value (α; H(k)) and a second gain value (1-α; 1-H(k)); generating an intermediate signal (V) including a linear combination of the first directional input signal (F<sub>L</sub>) and the second directional input signal (F<sub>R</sub>), in accordance with one or both of the first gain value (α; H(k)) and the second gain value (1-α; 1-H(k)); wherein one or both of the first gain value (α; H(k)) and the second gain value (1-α; 1-H(k)) are determined in accordance with an objective of making a proportion of the first directional input signal (F<sub>L</sub>) and a proportion of the second directional signal (F<sub>R</sub>) at least substantially equal when combined; and generating an output signal (Z) for the output unit (140) based on the intermediate signal.
