Abstract

There is provided a method of operating a system for providing hearing assistance to a user (101), comprising: capturing and processing audio signals by a transmission unit (102) and transmitting the audio signals from the transmission unit (102) via a wireless audio link to a receiver unit (103); processing the received audio signals in the receiver unit (103); stimulating the user'"'"'s hearing, by stimulating means (38, 136) worn at or in the user'"'"'s ear, according to the audio signals from the receiver unit (103); logging data by recording the values of at least one operation parameter of the transmission unit (102) and/or the receiver unit (103) as a function of time and/or by recording data derived from the values of at least one operation parameter of the transmission unit (102) and/or the receiver unit (103) as a function of time in the transmission unit (102); and reading the logged data from the transmission unit (102).

Claims

1. A method of operating a system for providing hearing assistance to a user, comprising:

(a) capturing and processing audio signals by a transmission unit and transmitting said audio signals from said transmission unit via a wireless audio link to a receiver unit;

(b) processing the received audio signals in said receiver unit;

(c) stimulating a hearing of said user, by stimulating means worn at or in an ear of said user, according to said processed audio signals from said receiver unit;

(d) logging data by at least one of recording values of at least one operation parameter of at least one of said transmission unit and said receiver unit as a function of time and recording data derived from values of at least one operation parameter of at least one of said transmission unit and said receiver unit as a function of time in said transmission unit; and

(e) reading said logged data from said transmission unit.

2. The method of claim 1, wherein said transmission unit is a remote device used spaced apart from said user by another person.

3. The method of claim 1, wherein said transmission unit is a device which is worn at a body of said user spaced apart from a head of said user and used by said user.

4. The method of claim 1, wherein said data derived from said values of at least one operation parameter of said transmission unit as a function of time is a time-average of said least one operation parameter.

5. The method of claim 1, wherein said data derived from said values of at least one operation parameter of said transmission unit as a function of time is a time-integrated value of said least one operation parameter.

6. The method of claim 5, wherein said logged data includes a total time of operation of said transmission unit.

7. The method of claim 1, wherein the audio signals are analyzed by a classification unit of said transmission unit prior to being transmitted in order to determine a present auditory scene category from a plurality of auditory scene categories.

8. The method of claim 7, wherein said logged data includes said determined auditory scene categories.

9. The method of claim 1, wherein said receiver unit is integrated within a hearing instrument comprising said stimulation means and a microphone arrangement.

10. The method of claim 1, wherein said receiver unit comprises said stimulation means.

11. The method of claim 1, wherein said logged data is read via a wired interface.

12. The method of claim 1, wherein said logged data is read via a wireless link.

13. The method of claim 12, wherein said logged data is read via a modulation of an audio channel of said audio link.

14. The method of claim 1, wherein said logged data read from said transmission unit is supplied as input to an internet expert system.

15. The method of claim 1, wherein data to be logged in said transmission unit is sent via a wireless data link from said receiver unit to said transmission unit.

16. The method of claim 15, wherein said wireless data link is part of a bidirectional data link between said transmission unit and said receiver unit for sending a polling signal from said transmission unit to said receiver unit, whereupon status information data regarding operation of said receiver unit is sent from said receiver unit to said transmission unit order to monitor a status of said receiver unit.

17. The method of claim 16, wherein said logged data includes at least one of status information data regarding said status of said receiver unit as a function of time and the times of sending said polling signal.

18. The method of claim 16, wherein said status information data includes at least one of a signal strength of said audio link, a presence and an extent of interfering signals, a battery status of said receiver unit and the proper functioning of said stimulating means.

19. The method of claim 1, wherein a real time clock signal is generated in said transmission unit and is regularly sent via a wireless data channel from said transmission unit to said receiver unit in order to regularly synchronize a timer of said receiver unit to said clock signal of said transmission unit.

20. A system for providing hearing assistance to a user, comprising:

a transmission unit for capturing and processing audio signals and transmitting said audio signals via a wireless audio link, a receiver unit for receiving and processing said audio signals from said transmission unit via said wireless link;

stimulating means worn at or in an ear of said user for stimulating a hearing of said user according to said processed audio signals from said receiver unit, means for logging data by at least one of recording values of at least one operation parameter of at least one of said transmission unit and said receiver unit as a function of time and recording data derived from the values of at least one operation parameter of at least one of said transmission unit and said receiver unit as a function of time in said transmission unit; and

means for reading said logged data from said transmission unit.
