Dynamic hearing aid system and a method for configuring the hearing aid system

1. A dynamic hearing aid system, comprising:

a first hearing device;

a second hearing device; and

a controller;

said first and second hearing devices and said controller being configured to communicate with each other;

said first and second hearing devices and said controller forming a master-slave configuration, wherein one of said first and second hearing devices is a master hearing device in said master-slave configuration and the other one of said first and second hearing devices is a slave hearing device; and

said slave hearing device being configured to detect a presence of said master hearing device and, upon determining that said master hearing device is absent, to act as a master.

2. The dynamic hearing aid system according to claim 1 , wherein said slave hearing device is configured, upon losing a connection with said master hearing device, to change a communication with said controller.

3. The dynamic hearing aid system according to claim 2 , wherein said slave hearing device is configured, upon losing a connection with said master hearing device, to suspend a communication of said slave hearing device with said controller.

4. The dynamic hearing aid system according to claim 2 , wherein said slave hearing device is configured, upon losing a connection with said master hearing device, to send a respective signal to said controller, informing said controller about an absence of said master hearing device.

5. The dynamic hearing aid system according to claim 1 , wherein said controller is configured to check whether said master hearing device is absent.

6. The dynamic hearing aid system according to claim 1 , wherein said controller is configured to transmit data to said slave hearing device at regular time intervals.

7. The dynamic hearing aid system according to claim 1 , wherein said slave hearing device and said master hearing device are battery driven devices.

8. A method of configuring a hearing aid system, the method comprising:

providing a first hearing device, a second hearing device, and a controller adapted to communicate with each other, wherein the first and second hearing devices and the controller form a master-slave configuration, with one of the hearing devices being a master hearing device and the other hearing device being a slave hearing device;

detecting a presence of the master hearing device by the slave hearing device; and

upon determining that the master hearing device is absent, acting as a master by the slave hearing device.

9. The method according to claim 8 , which further comprises changing a communication by the slave hearing device with the controller on losing a connection with the master hearing device.

10. The method according to claim 9 , wherein a change in communication by the slave hearing device comprises suspending a communication with the controller.

11. The method according to claim 9 , wherein a change in communication by the slave hearing device comprises transmitting a signal to the controller, informing the controller of an absence of the master hearing device.

12. The method according to claim 8 , which comprises verifying an absence of the master hearing device by the controller.

13. The method according to claim 8 , which comprises transmitting data by the controller to the slave hearing device at regular intervals of time.

14. The method according to claim 8 , which further comprises communicating a presence of master hearing device to the slave hearing device by the controller.

15. The method according to claim 8 , which comprises relaying data between the master hearing device and the slave hearing device.
