Method for operating a binaural hearing system and a binaural hearing system

A method for operating a binaural hearing system comprising a first and a second hearing device (1, 2), each comprising at least one input transducer (3, 4, 5, 6), a signal processing unit (7, 8), an output transducer (11, 12) and a link unit (9, 10) capable for exchanging information between the first and the second hearing device (1, 2), the method comprising the steps of:

• operating the first hearing device (1) according to a first processing scheme,
• operating the second hearing device (2) according to a second processing scheme,
• monitoring acoustic situation by the first hearing device (1),
• monitoring acoustic situation by the second hearing device (2),
• generating a request for coordinating the two hearing devices (1, 2) if one hearing device (1, 2) detects an acoustic situation asking for coordinating the two processing schemes of the first and the second hearing device (1, 2), the hearing device (1, 2) detecting such an acoustic situation being an ipsi-lateral hearing device (1, 2) the other being a contra-lateral hearing device (1, 2),
• activating a link between the ipsi-lateral hearing device (1, 2) and the contra-lateral hearing device (1, 2) for transmitting the request to the contra-lateral hearing device (1, 2),
• shutting down the link between the ipsi-lateral hearing device (1, 2) and the contra-lateral hearing device (1, 2) after the request has been transmitted to the contra-lateral hearing device (1, 2), and
• changing the processing scheme in at least one of the ipsi-lateral hearing device (1, 2) and the contra-lateral hearing device (1, 2) in accordance with the request.
