- the means for receiving the status information signal and displaying status information is adapted to display the status information graphically.
- the means for receiving the status information signal and displaying status information may be adapted to display the status information together with data identifying the audio signal receiver unit among a plurality of audio signal receiver units, whereby the displayed status information can be easily attributed to a certain person.
- the means for generating and transmitting the polling signal may be adapted to establish a radio frequency link to the means for receiving the polling signal, wherein the radio frequency link carrying the polling signal preferably uses the same channel as the radio frequency link carrying the audio signal, with the polling signal being transmitted by the audio signal transmitter.
- the means for generating and transmitting the polling signal may be adapted to establish an inductive link to the means for receiving the polling signal.
- the means for receiving the polling signal and the means for generating and wirelessly transmitting the status information signal comprise a powerless electromagnetic signal response means adapted to be energized by energy included in the polling signal, with the status information signal being encoded in a modulation of the polling signal by the powerless electromagnetic signal response means.

- the means for generating and transmitting the status information signal is adapted to use the same channel as radio frequency link carrying the audio signal, with the status information signal being transmitted via the antenna of the radio frequency receiver unit.
- the radio frequency transmitter and the radio frequency receiver unit in this case are preferably adapted to interrupt the radio frequency link carrying the audio signal while the status information signal is transmitted. This can be achieved by providing the radio frequency receiver unit with a RX/TX switch for the antenna.
- the status information signal and/or the polling signal will be transmitted at a data rate of 100 bps to 2 kbps.
- the means for generating and transmitting the polling signal and the means for receiving the polling signal at the audio signal receiver unit may be adapted to transmit remote control commands to the audio signal receiver unit, wherein the remote control commands may include commands for setting the frequency (channel) or frequency band of the wireless link carrying the audio signal and/or commands for setting the operation mode and operation parameters of the audio signal receiver unit, such as audio volume setting and gain setting.
- the remote control commands may include commands for setting the frequency (channel) or frequency band of the wireless link carrying the audio signal and/or commands for setting the operation mode and operation parameters of the audio signal receiver unit, such as audio volume setting and gain setting.
- the hearing system of Fig. 1 comprises a remote unit 10, an audio signal radio frequency receiver unit 12 and a hearing device 14.
- the hearing device 14 comprises an output transducer 16 for stimulation of a user's hearing, which typically will be an electro-acoustic transducer (speaker), with the hearing device 14 being designed such that the speaker 16 is located close to the outer and of the user's ear canal or within the ear canal when the hearing device 14 is worn by the user.
- the hearing device 14 comprises an audio signal processing unit 18 for processing the input audio signals to the output transducer 16.
- the hearing device 14 may be any type of headset or it may be a hearing aid / hearing instrument.
- the output transducer 16 could be a speaker, a cochlear implant (direct electrical stimulation of the inner ear) or an electro-mechanical transducer for direct mechanical stimulation of the middle ear or inner ear.
- the hearing aid may be arranged behind the ear, or partly or completely within the ear canal. In case that the hearing device 14 is not a hearing aid, it preferably may be a headset for a tourist tour guide or a museum guide system.
- the radio frequency receiver unit 12 may provide the input audio signals to the hearing device 14 via a standardized interface 20. Alternatively, the radio frequency receiver unit 12 may be integrated within the hearing device 14. In any case, the radio frequency receiver unit 12 is adapted to establish a radio frequency link 22 for wireless transmission of audio signals from the remote unit 10. Usually, the radio frequency link 22 will be a frequency modulated (FM) link.
- the remote unit 10 comprises an RF transmitter/ receiver 24 and the RF receiver unit 12 comprises a receiver/transmitter 26.
- the receiver/transmitters 24, 26 each comprise an antenna 28 and a transceiver 30.
- the remote unit 10 comprises an audio signal source 32 which is usually a microphone.
- the remote unit 10 preferably is a hand-held device, which picks up the voice of a person using the remote unit 10, such as a teacher in a classroom for persons with hearing loss or the guide of a tourist tour or a museum tour, via the microphone 32, with this audio signal being transmitted via the RF link 22 to the RF receiver unit 12 and from there to output transducer 16 in order to provide the user of the hearing device 14 with the voice of the person using the remote unit 10.
- the communication between the remote unit 10 and the RF receiver unit 12 would be unidirectional, namely from the remote unit 10 to the RF receiver unit 12, so that in a conventional system in the remote unit 10 only a RF transmitter function and in the RF receiver unit 12 only a RF receiver function would be necessary.
- such conventional system is modified such that the person using the remote unit 10 can easily monitor the RF audio link 22 by causing the RF receiver unit 12 to send status information regarding the status of the RF audio link 22 and/or the RF receiver unit 12 to the remote unit 10.
- This is achieved by providing the remote unit 10 with means for transmitting a polling signal/command 34 to the RF receiver unit 12 which is provided with means for receiving such polling signals 34.
- the RF receiver unit 12 is provided with means for generating and wirelessly transmitting, when the polling signal 34 has been received, a status information signal 36 containing data regarding the status of the RF link 22 and/or the RF receiver unit 12 to the remote unit 10 which is provided with means for receiving the status information signal 36 and displaying, via a display 38, status information derived from the status information signal 36.
- the remote unit 10 comprises a control unit 42 which controls the receiver/transmitter 24 and receives the status information signal from the transmitter/receiver 24 and an activation element 40 for causing the control unit 42 and the receiver/transmitter 24 to generate and wirelessly transmit the polling signal 34.
- the activation element 40 is manually operable in order to generate and transmit the polling signal 34.
- the RF receiver unit 12 comprises a control unit 44 which controls the transmitter/receiver 26, a non-volatile memory 46 and an analysis unit 48 for analyzing the audio signal received by the transmitter/receiver 26. Both the analysis unit 48 and the memory 46 communicate with the control unit 44.
- the memory 46 contains the program for operating the RF receiver unit 12 and data needed for operation of the RF receiver unit 12.
- the remote unit 10 and the RF receiver unit 12 preferably are designed such that the audio signal from the remote unit 10 can be transmitted through a plurality of different frequency bands/channels.
- a specific frequency channel can be used in order to avoid reception of audio signals from an adjacent classroom.
- the selection of the respective frequency channel for each RF receiver unit 12 may be achieved, for example, by a synchronization unit mounted at the wall of each classroom.
- the status information signal 36 would include information regarding the channel on which the respective RF receiver unit 12 is set. Thereby the teacher immediately could recognize from the display 38 whether the respective pupil wearing the respective RF receiver unit 12, for example, is using a wrong frequency channel so that he could not receive the audio signal transmitted by the remote unit 10.
- the status information signal 36 may contain information regarding the signal to noise ratio of the RF audio link 22 as detected by the analysis unit 48. Further, the status information signal may include information regarding the integrity of the electrical connections between the RF receiver unit 12 and the hearing device 14 via the interface 20.
- the RF link carrying the polling signal 34 uses the same channel as the RF audio link 22 and also the status information signal 36 uses the same channel as the RF audio link 22.
- the transmitter function of the transmitter/receiver 24 of the remote unit 10 may be used not only for the RF audio link 22 but also for the link for the polling signal 34.
- Transmission and reception of the status information signal 36 may occur via the antennas 28 of the remote unit 10 and the RF receiver unit 12, respectively, which are already used for the RF audio link 22.
- Such multiple use of the RF audio link channel can be achieved by interrupting the RF audio link 22 while the status information signal 22 or the polling signal 34 is transmitted.
- the status information signal 36 and the polling signal 34 typically are transmitted at a low data rate of 100 bps to 2 kbps.
- Fig. 2 shows an example of an alternative embodiment wherein the polling signal 34 and the status information signal 36 are not transmitted via the same channel as the RF audio signal but rather a separate wireless channel 50 is provided for transmission of the polling signal 34 and the status information signal 36.
- this separate channel 50 is an inductive link comprising an inductive antenna 52 provided at the remote unit 10 and connected with the control unit 42 and an inductive antenna 54 provided at the RF receiver unit 12 and connected with the control unit 44.
- the antennas 52 and 54 are adapted both for transmitting and receiving, with the antenna 52 transmitting the polling signal 34 and receiving the status information signal 36 and with the antenna 54 transmitting the status information signal 36 and receiving the polling signal 34.
- the inductive link 50 may be, for example, a 40 kHz FSK modulated inductive channel such as it is conventionally used for remote control purposes and programming of RF receiver units for hearing aids.
- the inductive link 50 in addition to transmitting the polling signal 34 and the status information signal 36, may be used for transmitting remote control commands to the RF receiver unit 12, such as commands for setting the frequency or frequency band of the audio RF link 22 and/or commands for setting the operation mode and operation parameters of the RF receiver unit 12, such as audio volume setting and gain setting.
- the receiver/transmitter 24 of Fig. 1 is replaced by an audio signal transmitter 25 comprising an antenna 28 and a transmitter element 31 replacing the transceiver 30.
- Fig. 3 shows an embodiment wherein the separate link 50 for the polling signal 34 and the status information signal 36 is realized as a powerless system by using a powerless electromagnetic signal response device 56 at the RF receiver unit 12.
- RFID radio frequency identification
- Such powerless response devices are known as radio frequency identification (RFID) systems and are commonly used, for example, in door access systems or theft surveillance systems.
- RFID-Handbook 2nd edition, by Klaus Finkenzeller, Wiley and Sons Ltd., April 2003 .
- the response device 56 is adapted to be energized by energy included in the polling signal 34,with the status information signal 36 being encoded in a modulation of the polling signal 34 caused by the response device 56.
- the range of RFID systems may be increased by powering the signal response device 56.
- the response device 56 may include an antenna 58, an analogue circuit for receiving and transmitting RF signals, a digital circuit and a data memory wherein the status information basic to a status information signal 36 is stored by action of the control unit 44.
- these RF receiver units 12 have to be addressed individually for gaining the desired status information signal 36 from a selected RF receiver unit 12. This can be achieved, for example, by transmitting dedicated device addresses from the remote unit 10 in order to specifically address a selected one of the RF receiver units 12. Such dedicated device addresses may be included in the polling signal 34. Such addresses may advantageously be programmable in both units 10 and 12.
- Another option is to achieve selection of the RF receiver unit 12 by controlling the range of the polling signal 34. This option is particularly appropriate if the polling signal 34 is transmitted via an inductive link, since the decay of inductive signals with the distance from the transmitter is extrernely steep. In this case, selection of the RF receiver unit 12 is practically achieved by approaching the selected RF receiver unit 12 with the remote unit 10 (for example, the teacher using a remote unit 10 approaches the pupil using the selected RF receiver unit 12).
- the status information signal 36 may include information on whether the RF receiver unit 12 is for a right ear or for a left ear. Such information can be provided, for example, by delaying the status information signal 36 depending on whether the RF receiver unit 12 is for a right ear or for a left ear.
