Method for operating a binaural hearing system as well as a binaural hearing system

1. A method for operating a binaural hearing system comprising at least a contra-lateral hearing device and an ipsi-lateral hearing device being operationally connected to one another via a communication link, wherein the contra-lateral hearing device and the ipsi-lateral hearing device are to be at least partly inserted into or to be worn behind respective ears of a user, each hearing device comprising at least one microphone to generate an electrical signal corresponding to an acoustic signal, the method comprising:

determining contra-lateral information (CLD) based on a first acoustic signal recorded by a microphone of the contra-lateral hearing device,

determining ipsi-lateral information (ILD) based on a second acoustic signal recorded by a microphone of the ipsi-lateral hearing device,

providing a coordination level, the coordination level being indicative of a degree of synchronization of settings related to audio signal processing within the contra-lateral hearing device and the ipsi-lateral hearing device, and

adjusting processes in the ipsi-lateral hearing device in accordance with the coordination level,

wherein the coordination level is determined from at least one of the contra-lateral information and the ipsi-lateral information, or is obtained from an external device, and

wherein the coordination level represents a partial degree of synchronization greater than no coordination and less than full coordination.

2. The method of claim 1 , further comprising:

adjusting processes in the contra-lateral hearing device in accordance with the coordination level.

3. The method of claim 1 , further comprising:

determining the contra-lateral information (CLD) in the contra-lateral hearing device, and

transmitting the contra-lateral information (CLD) to the ipsi-lateral hearing device.

4. The method of claim 1 , further comprising:

determining the ipsi-lateral information (ILD) in the ipsi-lateral hearing device.

5. The method of claim 1 , further comprising:

determining a coordination level in each of the two hearing devices.

6. The method of claim 1 , further comprising:

replacing the contra-lateral information (CLD) by the ipsi-lateral information (ILD) if the communication link fails.

7. The method of claim 1 , wherein the coordination level has a value that is greater than 0% coordination and less than 100% coordination.

8. The method of claim 2 , further comprising:

determining the contra-lateral information (CLD) in the contra-lateral hearing device; and

transmitting the contra-lateral information (CLD) to the ipsi-lateral hearing device.

9. The method of claim 2 , further comprising:

determining the ipsi-lateral information (ILD) in the ipsi-lateral hearing device.

10. A binaural hearing system comprising:

at least a contra-lateral hearing device and an ipsi-lateral hearing device being operationally connected to one another via a communication link, wherein the contra-lateral hearing device and the ipsi-lateral hearing device are to be at least partly inserted into or to be worn behind respective ears of a user,

each hearing device comprising at least one microphone to generate an electrical signal corresponding to an acoustic signal,

means for determining contra-lateral information (CLD) based on a first acoustic signal recorded by a microphone of the contra-lateral hearing device,

means for determining ipsi-lateral information (ILD) based on a second acoustic signal recorded by a microphone of the ipsi-lateral hearing device,

means for providing a coordination level, the coordination level being indicative of a degree of synchronization of the two hearing devices, and

means for adjusting processes in the ipsi-lateral hearing device in accordance with the coordination level,

wherein the coordination level is determined from at least one of the contra-lateral information and the ipsi-lateral information, or is obtained from an external device, and

wherein the coordination level represents a partial degree of synchronization greater than no coordination and less than full coordination.

11. The hearing system of claim 10 , further comprising:

means for adjusting processes in the contra-lateral hearing device in accordance with the coordination level.

12. The hearing system of claim 10 , further comprising:

means for determining the contra-lateral information (CLD) in the contra-lateral hearing device, and

means for transmitting the contra-lateral information (CLD) to the ipsi-lateral hearing device.

13. The hearing system of claim 10 , further comprising:

means for determining the ipsi-lateral information (ILD) in the ipsi-lateral hearing device.

14. The hearing system of claim 10 , further comprising:

means for determining a coordination level in each of the two hearing devices.

15. The hearing device of claim 10 , further comprising means for replacing the contra-lateral information (CLD) by the ipsi-lateral information (ILD) if the communication link fails.

16. The hearing system of claim 10 , wherein the coordination level has a value that is greater than 0% coordination and less than 100% coordination.

17. The hearing system of claim 11 , further comprising:

means for determining the contra-lateral information (CLD) in the contra-lateral hearing device; and

means for transmitting the contra-lateral information (CLD) to the ipsi-lateral hearing device.

18. The hearing system of claim 11 , further comprising:

means for determining the ipsi-lateral information (ILD) in the ipsi-lateral hearing device.
