Definitions

  • the invention relates to a hearing aid system for binaural supply with two hearing aids, with microphones, signal processing units, headphones and controls, with a signal exchange is provided between the hearing aids.
  • a hearing aid system of this type is known from DE 23 60 342 C2.
  • the handset is replaced with an induction coil in one of the hearing aid devices.
  • an induction coil is also provided for the reception with the hearing coil of the first hearing aid.
  • a head-worn hearing aid with two hearing aids is known in which one of the two hearing aids a Seride highlighted and the second hearing aid a receiving device for an optical signal transmission from the first hearing aid to the second hearing aid.
  • a hearing aid system with two hearing aids is known, between which a signal path for the wireless transmission of audio signals is present. It is provided that an audio signal generated in the first hearing device is transmitted to the second hearing device and is processed there before it is transmitted back to the first hearing device and supplied to the listener of the first hearing device for output.
  • a hearing aid is described in DE 19 38 381 A1, in which the volume control is done by means of a wireless remote control.
  • Known hearing aid systems with two hearing aids in which a signal exchange between the two hearing aids is provided, have the disadvantage that it requires a separate operation of both hearing aids for individual adaptation of the hearing aid system, for example with respect to the choice of the hearing program. If a remote control is used that acts on both hearing aids equally, it is disadvantageous because it must always be carried. Furthermore, the hearing aids of the known hearing aid systems comprise complex signal processing units.
  • Object of the present invention is to simplify a hearing aid system of the type mentioned above with respect to his hearing aid devices.
  • those of the operating elements for adjusting the one hearing aid device generated control signals transmitted to the second hearing aid and the two hearing aids are adjusted by these control signals.
  • Known controls on hearing aids are, for example: on-off switch, input selector for microphone or horn, amplification, sound, microphone or program selector switch.
  • the controls allow the hearing aid to adapt to the needs. They may be adjustable stepwise (e.g., switches) or continuously (e.g., actuator resistances).
  • the invention realizes the function of a remote control, but avoids their disadvantages, since the transmitting unit is integrated with the hearing aid.
  • the invention has the advantage that no separate remote control must be carried.
  • To adapt the two hearing aids it is sufficient to operate one of the two hearing aids. This is particularly advantageous when switching to another hearing program. In conventional hearing aid systems, it may happen that one of the two devices is operated in the wrong hearing program. This is particularly disadvantageous when e.g. one device with directional microphone and the other is operated omnidirectional. Total disorientation could be the result.
  • a hearing aid system according to the invention enables a simultaneous switching of both devices and thus avoids the disadvantages of conventional solutions.
  • the invention it is provided to divide the controls at least partially on both hearing aids. This has the consequence that no longer any type of controls on each of the hearing aids is present and thus less space overall for the attachment of controls is required, making the remaining controls executed correspondingly larger or, with unchanged size of the controls, the housing of the Hearing aids can be scaled down accordingly.
  • both hearing aid devices each have a volume control is provided, when it does not come to a signal exchange according to the invention, so that the gain can be set separately in both hearing aids, which contributes to a different hearing impairment of the two ears of a hearing aid wearer .
  • Other controls such as the input selector switch for microphone or horn, the tone control or the program selector switch are distributed according to the invention on both hearing aids. The actuation of one of the latter control elements thus leads to a simultaneous adaptation of both hearing aids.
  • a variant of the hearing aid system according to the invention provides that at least some of the operating elements have the option of adjusting the other hearing aid device when these operating elements are actuated.
  • Such settings can be set, for example, when programming the hearing aid system. This increases the number of applications for hearing aid systems according to the invention while reducing the device variants.
  • one and the same hearing aid are used in a hearing aid wearer with equally pronounced hearing impairment, who wishes to change the volume control only one of the two hearing aids and this change then affects both hearing aids equally.
  • the same hearing aid can also be used in a hearing aid wearer with varying degrees of hearing loss, who wishes to adjust the volume of both devices individually.
  • a further variant of the invention provides that only one of the two hearing aids has means for signal processing, which process audio signals received by the microphone of this hearing aid and by the microphone of the second hearing aid and transmitted to the first hearing aid, and wherein processed audio signals to the own listener or after a transmission of processed audio signals to the second hearing aid device, these can be supplied to the listener of the second hearing aid device.
  • the processing of recorded by the microphones of both hearing aids audio signals in only one signal processing unit offers the smaller size of one of the two hearing aids even more advantages.
  • the spatial hearing and the suppression of noise can be substantially improved.
  • a cost saving is possible by eliminating a signal processing unit in one of the hearing aids.
  • the external structure of the hearing aid in question can be made correspondingly smaller and lighter and also the power consumption decreases, whereby the capacity and thus the size of the voltage source can be adjusted accordingly.
  • Audio signals first signal pre-processing before they are fed to a common signal processing unit.
  • This signal pre-processing includes, for example, AD conversion with band-pass filtering.
  • the processed audio signals of the respective hearing aid are post-processed before being supplied to the listeners.
  • This signal post-processing includes, for example, DA conversion and amplification.
  • the desire for the smallest possible designs of hearing aids can be realized according to the invention best by the fact that the majority of the controls of the hearing aid system is not located on the hearing aid, which has the means for signal processing of the received audio signals from both microphones. Since in this hearing aid device, the remaining signal processing unit with respect to the signal processing unit of the other hearing aid is designed substantially smaller and less powerful, less space is required for it. As a further consequence, the energy consumption of this hearing aid is substantially reduced, so that the voltage source can be dimensioned correspondingly smaller. These effects compensate for the increased space requirement for the larger number of operating elements on this hearing aid. Overall, thus the design of both hearing aids can be reduced.
  • a variant of the invention provides a wired transmission and another variant wireless transmission, for example in the form of electromagnetic waves before.
  • the transmitted signals can be both analog and digital signals.
  • the exchange of audio and / or control signals via located on each of the hearing aid means for transmitting and / or receiving these signals in conjunction with a telecoil, as in conventional hearing aid devices for inductive recording magnetic useful signals already is available.
  • the cost of additional components for carrying out the invention is limited to a minimum.
  • wireless programming or remote control of the hearing aid devices can also take place via the telephone coils.

  • the Control element 5 comprises a button 12, which makes it possible to choose between different hearing programs. For example, if there are three hearing programs to choose from, you can switch to the next program by pressing a button. A possible switching sequence of the programs 1 to 3 would be 1-2-3-1.
  • the control signal 7 generated by the actuation of the button 12 is forwarded in analog or digital form to the signal processing unit 3. In addition, the control signal 7 is also fed to the transmitting and / or receiving unit 9.
  • the control 6 is the volume control. It comprises a gain controller 10 and an AD converter with memory 17.
  • the resulting control signal 8 is also forwarded here to the signal processing unit 3 and the transmitting and / or receiving unit 9.
  • the forwarding to the transmitting and / or receiving unit 9 via the programmable switch 16 takes place here.
  • the programming of the switch 16 takes place via the control signal 8.
  • the telecoil 13 By opening and closing the switch 16 can be set whether the volume setting is transmitted from one hearing aid to another.
  • the control element 5 serves as a program selector switch and a push button 12
  • the control element 5 'in the hearing aid 1' serves as input selector switch for microphone or listening coil and has for this purpose a slide switch 11 'with two stable end positions.
