Abstract

A method for operating a hearing device is specified. The hearing device is assigned to a user and connected to other hearing devices, which are each assigned to another user, for data exchange in a common network. The hearing device or one of the other hearing devices controls the data exchange by subscribing to the network as a master, and wherein all other hearing devices subscribe to the network as a slave. It is decided whether the hearing device subscribes to the network as a master or as a slave by determining the operational capability of the hearing device and comparing it with the operational capability of the other hearing devices and by the hearing device acting as a master if the hearing device has the highest operational capability, and otherwise as a slave.

First claim

The invention claimed is:

1. A method for operating a hearing device, which comprises the steps of:
assigning the hearing device to a user and the hearing device is or will be connected to other hearing devices each assigned to another user, for data exchange in a common network, wherein:
the hearing device or one of the other hearing devices controls the data exchange by subscribing to the common network as a master, and all the other hearing devices each subscribe to the common network as a slave, the decision of whether the hearing device subscribes to the common network as a master or as a slave being made before the hearing device joins the common network, the common network being a decentralized and relay-free network, in which the hearing device and the other hearing devices are directly connected to each other, and additional devices which are not hearing devices are omitted from the network, at least for a data exchange between the hearing devices;
it is decided whether the hearing device subscribes to the network as the master or as the slave by determining an operational capability of the hearing device and comparing it with the operational capability of the other hearing devices, and by the hearing device subscribing as the master if the hearing device has a highest operational capability, and otherwise as the slave;
a search mode of the hearing device is activated if it is not currently subscribed to the common network; and
in the search mode the hearing device emits a search signal, which contains the operational capability of the hearing device so that it can be received by another hearing device and compared with the operational capability thereof.

2. The method according to claim 1 , which further comprises determining the operational capability based on a charge state of an energy storage unit of the hearing device, so that the hearing device subscribes to the common network as the master if the charge state of the hearing device is greater than the charge state of all the other hearing devices in the common network, and otherwise as the slave.

3. The method according to claim 1 , which further comprises determining the operational capability based on a transmission quality of the hearing device with respect to transmission and reception of data over the common network, so that the hearing device subscribes to the common network as the master if the transmission quality of the hearing device is greater than the transmission quality of all the other hearing devices in the common network, and otherwise as the slave.

4. The method according to claim 1 , which further comprises determining the operational capability based on an error rate in the data exchange, so that the hearing device subscribes to the common network as the master if the error rate of the hearing device is lower than the error rate of all the other hearing devices in the common network, and otherwise as the slave.

5. The method according to claim 1 , which further comprises selecting the hearing device as a new master of the common network if the hearing device joins the common network and the common network already has an old master, but the operational capability thereof is worse than the operational capability of the hearing device, so that from now on the old master subscribes to the common network as the slave.

6. The method according to claim 1 , wherein in an event that the hearing device is already subscribed to the common network as the master and a new hearing device joins the common network, it is decided once again whether the hearing device subscribes to the common network as the master or as the slave.

7. The method according to claim 1 , wherein in an event that the hearing device is already subscribed to the common network as the slave and the master leaves the common network, it is decided once again whether the hearing device subscribes to the common network as the master or as the slave.

8. The method according to claim 1 , wherein in the search mode, the hearing device listens to whether the other hearing devices are within range and receives their search signals in order to compare a respective operational capability of the other hearing devices with its own said operational capability.

9. The method according to claim 1 , wherein during the data exchange over the common network, audio data is exchanged which is obtained by acquiring a speech of the assigned user by means of the hearing device.

10. The method according to claim 1 , wherein the common network is a wireless network.

11. A hearing device, comprising:
a controller configured to carry out a method according to claim 1 .

12. A method for operating a hearing device, which comprises the steps of:
assigning the hearing device to a user and the hearing device is or will be connected to other hearing devices each assigned to another user, for data exchange in a common network, wherein:
the hearing device or one of the other hearing devices controls the data exchange by subscribing to the common network as a master, and all the other hearing devices each subscribe to the common network as a slave, the decision of whether the hearing device subscribes to the common network as a master or as a slave being made before the hearing device joins the common network;
it is decided whether the hearing device subscribes to the network as the master or as the slave by determining an operational capability of the hearing device and comparing it with the operational capability of the other hearing devices, and by the hearing device subscribing as the master if the hearing device has a highest operational capability, and otherwise as the slave;
a search mode of the hearing device is activated if it is not currently subscribed to the common network;
in the search mode the hearing device emits a search signal, which contains the operational capability of the hearing device so that it can be received by another hearing device and compared with the operational capability thereof; and
the search mode is activated by the hearing device detecting a voice that is not the voice of an assigned user of the hearing device.

13. A method for operating a network having a plurality of hearing devices assigned to different users, which comprises the steps of:
selecting one of the hearing devices as a master, for controlling a data exchange between the hearing devices, and wherein all other ones of the hearing devices are selected as a slave, wherein the hearing device having a highest operational capability compared to the other hearing devices is selected as the master, the decision of whether a particular hearing device subscribes to the common network as a master or as a slave being made before the particular hearing device joins the common network, the common network being a decentralized and relay-free network, in which the hearing device and the other hearing devices are directly connected to each other, and additional devices which are not hearing devices are omitted from the network, at least for a data exchange between the hearing devices; and
activating a search mode of the hearing device if it is not currently subscribed to the network, wherein in the search mode the hearing device emits a search signal which contains the operational capability of the hearing device so that it can be received by another hearing device and compared with the operational capability thereof.
