Abstract (en)
[origin: EP2672732A2] The method involves detecting head movements of a user (1) wearing a hearing instrument (2). Acoustic signals are captured in direction-dependent manner upon determining absence of movements. Amplification of the signals, which originate from a focus solid angle in front of the head as compared with signals originating from other solid angles, is subsequently boosted. The amplification of the signals is gradually focused by reducing the focus solid angle when presence of the desired signals originating from the focus solid angle decreases on account of reducing the focus solid angle.
