Abstract: The present invention proposes a method for operating a binaural hearing system with two hearing devices (1, 1?) operationally interconnected by means of a bidirectional link (8) which improves hearing perception in windy listening situations. The method comprises determining the level of wind noise present at each of the two hearing devices (1, 1?) and sending the audio signal picked-up at the first hearing device (1) to the second hearing device (1?) via the link (8) and then providing an output signal derived from the received signal to the electrical-to-mechanical output converter (3?) of the second hearing device (1?) if the level of wind noise at the second hearing device (1?) exceeds the level of wind noise at the first hearing device (1) by a pre-set threshold value. Furthermore, a binaural hearing system capable of performing such a method is given.
