(54) | METHOD AT A HEARING DEVICE |
(57) 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 (FL); a communications unit (120) configured to receive a second directional input signal
(FR) 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 (FL) and the second directional input signal (FR), 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 (FL) and a proportion of the second directional signal (FR) at least substantially equal when combined; and generating an output signal (Z)
for the output unit (140) based on the intermediate signal.
