Abstract

Data is wirelessly transferred between a hearing aid and an external device, wherein the hearing aid via an internal receiving device, receives data being sent form the external device via a wireless connection. The hearing aid is in a receiving mode when data from the external device is sent via the wireless connection, wherein the receiving device is then permanently in the on-position for receiving data. Furthermore, the hearing aid switches to a stand-by mode, when no data is sent via the wireless connection from the external device, wherein the receiving device is alternatively turned on and off, in order to detect a beginning data transfer from the external device.

Claims

1-16. -16. (canceled)

17. A method for a wireless data transfer between a hearing aid and an external device, comprising:

receiving data sent from the external device by an internal receiving device in the hearing aid, the data received via a wireless connection;

switching the hearing aid into a receiving mode in response to the receiving data;

wherein while the internal receiving device is in the receiving mode the internal receiving device is constantly switched on in order to receive the data; and

switching the hearing aid to a standby mode in response to no data being received from the external device via the wireless connection,

wherein while the internal receiving device is in the standby mode the internal receiving device is alternately switched on and off in order to detect the receipt of further data from the external device via the wireless connection.

18. The method as claimed in claim 17, wherein the hearing aid in the switched-on phase of the standby mode changes to the receiving mode when the internal receiving device detects the receipt of the further data from the external device via the wireless connection.

19. The method as claimed in claim 17, wherein the hearing aid changes from the receiving mode to the standby mode when the internal receiving device within a prespecified time detects no data being received from the external device via the wireless connection.

20. The method as claimed in claim 17,

wherein the duration of the switched-on and switched-off phases of the internal receiving device in standby mode is selected in order to detect the receipt of the further data from the external device via the wireless connection.

21. The method as claimed in claim 17, wherein the hearing aid receives an activation signal from the external device via the wireless connection in order to indicate to the hearing aid the start of a further data.

22. The method as claimed in claim 21, wherein the duration of the activation signal exceeds the duration of the switched-off phase of the internal receiving device in the standby mode of the hearing aid.

23. The method as claimed in claim 21,

wherein the activation signal comprises an activation message and a redundant preamble, and

wherein the duration of the redundant preamble is selected so that the total duration of the activation signal exceeds the duration of the switched-off phase of the internal receiving device in the standby mode of the hearing aid.

24. The method as claimed in any one of claim 20, wherein the activation message in the activation signal is repeated until the total duration of the activation signal exceeds the duration of the switched-off phase of the internal receiving device in the standby mode of the hearing aid.

25. The method as claimed in claim 17,

wherein the external device uses a specific modulation in order to indicate the start of the further data and

wherein the hearing aid changes to the receiving mode when the internal receiving device receives a data with the specific modulation.

26. The method as claimed in claim 25, wherein the hearing aid changes to the receiving mode when the internal receiving device receives a data with the specific phase or the frequency modulation.

27. The method as claimed in claim 17,

wherein a data receipt occurs within the scope of wireless programming of the hearing aid, and

wherein the hearing aid in a programming mode receives programming data from the external device serving as a control device in order to wirelessly program the hearing aid.

28. The method as claimed in claim 27, further comprising:

changing the hearing aid to the programming mode as soon as a special command is received from the control device via the wireless connection,

wherein programming data received by the hearing aid outside of the programming mode via the wireless connection is ignored by the hearing aid.

29. The method as claimed in claim 27, further comprising:

preventing a change of the hearing aid to the standby mode when the hearing aid is in the programming mode.

30. The method as claimed in claim 27, further comprising:

automatically changing the hearing aid from the programming mode to the receiving mode or the standby mode after an expiry of a prespecified time.

31. The method as claimed in claim 30, wherein the automatic changing the hearing aid from the programming mode to the receiving mode or the standby mode is prevented when another programming access via the wireless connection is made within the prespecified time.

32. The method as claimed in claim 31, wherein the hearing aid in the programming mode resets the time for the automatic change when another programming access takes place or when the hearing aid receives an audio data flow.

33. A hearing, comprising:

an internal receiving device to receive data from an external device via a wireless connection,

a plurality of operating modes in which a behavior of internal receiving device is modified based on a current operating mode.

wherein when the current operating mode is a receiving mode the internal receiving device is constantly switched on,

wherein when the current operating mode is a standby mode the internal receiving device is alternately switched on and off,

wherein the current operating mode is switched from the receiving mode to the standby mode when no data is received from the internal receiving for a predetermined duration of time, and

wherein the current operating mode is switched from the standby mode to the receiving mode when data is received during the switched on phase of the internal receiving device.

34. The hearing aid as claimed in claim 33,

wherein the duration of the switched-on and switched-off phases of the internal receiving device in standby mode is selected in order to detect the receipt of the data from the external device via the wireless connection,

wherein the hearing aid receives an activation signal from the external device via the wireless connection in order to indicate to the hearing aid the start of a transfer of data, and

wherein the duration of the activation signal exceeds the duration of the switched-off phase of the internal receiving device in the standby mode of the hearing aid.

35. The hearing aid as claimed in claim 34,

wherein when the current operating mode is a programming mode the external device serves as a control device to wirelessly program the hearing aid,

wherein the current operating mode is changed to the programming mode after a receipt of a special command from the control device via the wireless connection, and

wherein programming data received by the hearing aid when the current operating mode is not the programming mode is ignored by the hearing aid.

36. The hearing aid as claimed in claim 35, wherein when the current operating mode is in the programming mode a change to the standby mode is prevented.
