METHOD FOR OPERATING A BINAURAL HEARING SYSTEM AND BINAURAL HEARING SYSTEM

摘要

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.

1. A method for operating a binaural hearing system comprising a first and a second hearing device (1, 1′) operationally interconnected by means of a bidirectional link (8) and each having a microphone arrangement (2, 2′) and an electrical-to-mechanical output converter (3, 3′), the method comprising the steps of:
capturing a first audio signal with the microphone arrangement (2) of the first hearing device (1) being worn at one ear of a user; capturing a second audio signal with the microphone arrangement (2′) of the second hearing device (1′) being worn at the other ear of the user; determining a level of a first wind noise based on the first audio signal; determining a level of a second wind noise based on the second audio signal; sending
an ancillary signal derived from the first audio signal from the first hearing device (1) to the second hearing device (1′) if the level of the second wind noise exceeds the level of the first wind noise by a pre-set threshold value (Thmin), oran ancillary signal derived from the second audio signal from the second hearing device (1′) to the first hearing device (1) if the level of the first wind noise exceeds the level of the second wind noise by the pre-set threshold value (Thmin); and providing
a first output signal derived from the ancillary signal to the electrical-to-mechanical output converter (3) of the first hearing device (1) if the level of the first wind noise exceeds the level of the second wind noise by a pre-set threshold value (Thmin), ora first output signal derived from the ancillary signal to the electrical-to-mechanical output converter (3′) of the second hearing device (1′) if the level of the second wind noise exceeds the level of the first wind noise by a pre-set threshold value (Thmin).
