Definitions

  • the present invention relates to a system for providing binaural hearing assistance to a user comprising a left ear unit to be worn at or in the user's left ear and a right ear unit to be worn at or in the user's right ear, wherein each of the left ear unit and the right ear unit comprises means for stimulating the user's hearing and an inductive antenna for enabling bidirectional communication between the units via an inductive link.
  • DE 10 2004 016 573 Bl relates to such a binaural system wherein two in-the-ear (ITE) hearing aids are provided with antenna coils in such a manner that the symmetry axes are oriented substantially horizontally and coaxially with respect to each other when the hearing aids are worn in the user's ear canals in order to optimize the inductive coupling between the two antennas. This is particularly important in view of the relatively restricted power budget of hearing aids.
  • ITE in-the-ear
  • a vertical antenna integrated into the housing of a behind the ear (BTE) hearing aid for bidirectional communication with a remote programming device is described in DE lOl 15 896 Al, wherein the hearing device may be part of a binaural system.
  • the receiver/transmitter unit connected to the antenna is removed from the hearing aid during times when no communication with the remote programming unit is necessary.
  • DE 102 36 940 B3 relates to a hearing aid comprising an antenna coil wound around the housing of the hearing aid microphone or the hearing aid loudspeaker for communication with a remote device.
  • the hearing aid may be part of a binaural system.
  • US 6,594,370 Bl relates to a wireless communication system comprising two ear pieces which communicate wirelessly with a remote processor unit worn at the neck.
  • a necklace is provided into which patch antenna arrays are integrated for establishing a wireless link to the ear pieces.
  • a remote control for hearing aids as a wrist watch-like device, wherein the antenna for providing a wireless link to the hearing aid is integrated within the band of the wrist-watch.
  • An examples for such a remote control is given in DE 36 42 828 Al.
  • the solution according to claim 1 is beneficial in that, by arranging the antennas of the right ear unit and the left ear unit in a substantially vertical, parallel orientation and by arranging the antenna of the body-worn device in a substantially vertical orientation parallel to the antennas of the of the right ear unit and the left ear unit, the inductive coupling between the body-worn device and the right ear unit and/or left ear unit is optimized while still an acceptable inductive coupling between the right ear unit and the left ear unit is achieved. Although the efficiency of the inductive coupling between the right ear unit and the left ear unit is reduced compared to the case of a horizontal axially aligned arrangement of the antennas, the overall performance of the system can be improved by such vertical antenna arrangement.
  • the inductive coupling to the body-worn device can be improved due to the fact that usually a vertical antenna arrangement can be realized more easily in the body-worn device than a horizontal antenna arrangement. Another reason is that for a vertical antenna arrangement the left ear unit and the right ear unit usually allows for more antenna space, so that the reduced inductive coupling can be compensated by an extended length of the antennas. Such extended antennas can be realized particularly easy for BTE hearing aids.
  • the solution according to claim 16 is beneficial in that, by orienting the antennas of the left ear unit and the right ear unit substantially horizontally and substantially aligned to each other and by orienting the antenna of the body-worn device substantially horizontally and substantially parallel to the antennas of the left ear unit and the right ear unit, an optimized inductive coupling both between the left ear unit and the right ear unit and the body-worn device is achieved.
  • Fig. 1 is a schematic view of a first embodiment of a binaural system according to the invention comprising a left ear unit and the right ear unit and several examples of body- worn devices;
  • Fig. 2 is a view like Fig. 1 of a second embodiment
  • Fig. 3 is a block diagram of an example of a left ear/right ear unit to be used in the embodiment of Fig. 1 or 2;
  • Fig. 4 is a block diagram of an example of remote device to be used in the embodiment of Fig. 1 or 2.

To this end, the audio signal processing unit 14 usually will select one audio program from a plurality of different audio programs depending on the presently captured audio signals.
  • audio signal processing unit 14 in addition to the audio signals from the microphone 12 also may take into account audio signals received by the receiver/transmitter unit 20 from the other one of the hearing aids 1OA, 1OB, i.e. audio signals captured by the microphone 12 of the other one of the hearing aids 1OA, 1OB, in order to render the result of the auditory scene analysis more reliable.
  • information regarding the presently selected audio program may be exchanged between the hearing aids 1OA, 1OB, and such information regarding the presently selected audio program of the other one of the hearing aids 1OA, 1OB may be taken into account when selecting the audio program.
