Definitions
- the invention relates to a hearing aid device system with two head-worn hearing aids for binaural care of a hearing aid wearer, the hearing aid each having an input transducer for receiving an input signal and conversion to an electrical signal, a signal processing unit for processing and frequency-dependent amplification of the electrical signal and an output transducer for the conversion of in the hearing aid devices, parameters for controlling the signal processing in the signal processing units are adjustable for adapting the signal processing to different auditory situations and wherein control signals can be transmitted between the two hearing aids for adaptation in a hearing aid set parameters to the parameters set in the other hearing aid. Furthermore, the invention relates to a method for operating such a hearing aid device system.
- Hearing aids usually have an audio input for connection to external devices such as radio, television, CD players, MP3 players, etc.
- the connection between the hearing aid and the external device is either wireless or wired.
- the hearing aid in question is connected to the audio reception with a so-called "audio shoe”. Starting from the audio shoe, a wire can then lead to the external device.
- audio shoes which include a transmitting and receiving unit for wireless data transmission between the hearing aid and an external device.
- Such wireless systems are used for example in training rooms for the hard of hearing and are known under the name "MLX”.
- Hearing aid systems for the binaural care of a deaf person are often operated asymmetrically for audio reception. Only one of the two hearing aids is connected to the audio signal source. In this mode of operation, the adjustment of settings of the two hearing aid devices of the hearing aid system is impractical.
- Object of the present invention is to provide a meaningful in terms of their settings coupling two hearing aids of a binaural hearing aid system in audio reception.
- a hearing aid device system with two head-worn hearing aids for the binaural supply of a hearing aid wearer, the hearing aid each having an input transducer for receiving an input signal and conversion into an electrical signal, a signal processing unit for processing and frequency-dependent amplification of the electrical signal and an output transducer for converting the processed signal into a perceptible by the hearing aid wearer signal as an audible signal, wherein the hearing aid parameters for controlling the signal processing in the signal processing units are adjustable to adapt the signal processing to different auditory situations and whereby control signals can be transmitted between the two hearing aid devices for adapting the parameters set in a hearing aid device to the parameters set in the other hearing aid device, in that in a hearing situation for "audio reception" the adjustment of the set parameters between the two hearing aids is at least partially prevented is.
- an input signal is recorded by means of an input transducer and converted into an electrical input signal.
- an input transducer usually serves as an input transducer at least one microphone which receives an acoustic input signal.
- Modern hearing aids often include a microphone system with a plurality of microphones to a dependent of the direction of incidence acoustic signals reception, a Directional characteristic to achieve.
- the input transducers may also include a telecoil or antenna for receiving electromagnetic input signals.
- the input signals converted by the input transducer into electrical input signals are fed to a signal processing unit for further processing and amplification. The further processing and amplification takes place to compensate for the individual hearing loss of a hearing aid wearer, as a rule, as a function of the signal frequency.
- the signal processing unit outputs an electrical output signal, which is fed via an output transducer to the hearing of the hearing aid wearer, so that the latter perceives the output signal as an acoustic signal.
- output transducers usually listeners are used, which generate an acoustic output signal.
- output transducers for generating mechanical vibrations are also known, which directly excite certain parts of the ear, such as the ossicles, to vibrate.
- output transducers are known which directly stimulate neurons of the ear.
- Hearing aids are usually by different modes (hearing programs) adjustable to different listening situations. Such auditory situations are, for example, "quiet environment", “television”, “conversation in noise”, etc.
- Another hearing situation is the audio reception in which the hearing aid is connected via an electrical or electromagnetic connection directly to an audio signal source.
- the coupling in the auditory situation "audio reception" is at least largely interrupted. This means that manual settings on one of the two hearing aids or automatically performed parameter changes no longer affect the other hearing aid.
- a hearing aid which is placed in the active audio mode sends a control signal to the second hearing aid and thus puts this automatically in the passive audio mode, if the second hearing aid is not also in the active audio mode.
- the special settings of the hearing aid device in the active or passive audio mode can preferably be adjusted during the adaptation of the hearing aid by a hearing aid acoustician.
- the signal source corresponding to the request of the hearing aid wearer can thereby be used as the input signal of the relevant hearing aid device.
- the microphone signal is obvious in order to be able to perceive outside noise, or also to mute the hearing aid device.
- the mutual control of setting parameters in the binaural hearing aid system is at least largely eliminated. If an audio reception is provided in both hearing aid devices, preferably no interaction at all takes place in this mode of operation at all.
- a remote control is included in the hearing aid system, their operation may affect both hearing aids. For example, a volume adjustment lead to a relative change in the volume setting of both hearing aids, the set balance is maintained because of the canceled absolute value coupling.
- a program changeover carried out by means of the remote control preferably only leads to an adaptation of the hearing aid device in the audio mode to different signal sources, e.g. pure audio reception or mixed operation "audio reception” and "microphone reception". A hearing aid in the passive audio mode is then not affected by such a program switch.
- the hearing aid system preferably returns to the settings concerning the hearing aids, which it before recording the audio Operation had.
- the hearing aid device formerly operated in the active audio mode presets the volume setting, and the second hearing aid device is slowly adapted to this setting ("fading") if the volume is required.
- the figure shows a hearing aid system with a hearing aid device 1 which can be worn behind the left ear and a hearing aid device 2 which can be worn behind the right ear for the binaural supply of a hearing aid wearer.
- a microphone 10 or 14 is used to record an acoustic input signal and conversion into an electrical signal.
- This is further processed in each case in a signal processing unit 11 or 15 and amplified in response to the signal frequency to compensate for the individual hearing loss of the hearing aid wearer.
- the processed and amplified signal is in each case converted back into an acoustic signal by means of a receiver 12 or 16 and supplied to the hearing aid wearer via the sound channels 13 and 17 and sound tubes (not shown) connected thereto.
- wireless coupling is provided so that automatically or manually performed changes in settings in one of the two hearing aids show effects on the other hearing aid. If e.g. operated by the volume control 4 or by pressing the program selection button 3, the hearing aid 1 manually, so the volume is changed or the active hearing program switched without the need to operate the program selection button 5 and the volume control 6 in the hearing aid 2.
- the hearing aid device system is in the audio mode, since at least one of the hearing aid devices (hearing aid device 1) is connected to an audio shoe 7. In the exemplary embodiment, this is attached to the lower end of the hearing aid 1.
- the audio shoe 7 in the exemplary embodiment comprises a receiving unit for the wireless reception of an electromagnetic signal emanating from an audio signal source.
- the audio signal source is executed in the embodiment as a CD player 8 with a transmitter.
- operation of the controls 3 or 4 has no effect on the Hearing aid device 2.
- an actuation of the operating elements 5 or 6 on the hearing aid 2 does not affect the hearing aid device 1.
- the hearing aid 1 When attaching the audio shoe 7 on the hearing aid 1 this is switched to the active audio mode. Thereafter, the hearing aid 1 sends a signal to the hearing aid 2, which is not connected to an audio shoe and is therefore placed in the passive audio mode.
- the hearing aid device 2 In the passive audio mode, the hearing aid device 2 is set in accordance with the user's specifications set in the programming of the hearing aid device 2, e.g. on microphone reception or mute. Apart from the transfer of the hearing aid 2 in the passive audio mode by the hearing aid 1 takes place during the audio operation no further mutual interference of the hearing aid 1 and 2.
- the hearing aid 1 After completion of the audio mode, i. by releasing the audio shoe 7 from the hearing aid 1, the hearing aid 1 falls back to the original operating mode in which it had been before the beginning of the audio mode. Furthermore, a signal is transmitted from the hearing aid device 1 to the hearing aid device 2, which also indicates this to the end of the audio operation and returns it to the original operating mode.
- the hearing aid system further comprises a remote control 9.
- This has the labeled program with 1 to 4 program buttons for program selection and a rocker switch 18 for volume adjustment.
- a program change by pressing one of the labeled 1 to 4 keys only affects the hearing aid 1 from.
- a change in the volume setting by actuation of the rocker switch 18, on the other hand has an effect on both hearing aid devices 1 and 2 in that the volume is raised or lowered by a certain amount in both hearing aid devices 1 and 2.
- a meaningful adjustment of the hearing aid devices is also achieved in audio mode by direct operation of one of the two hearing aid devices or by operation of the hearing aid system by means of a remote control.
- the remote control also remains useful in connection with a binaural hearing aid system with coupled settings with one or two-sided use of an audio shoe.
- the hearing aid system automatically adapts to the preferences of the hearing aid wearer in this particular hearing situation.

Hörhilfegeräte weisen in der Regel einen Audio-Eingang zur Verbindung mit externen Geräten wie Radio, Fernseher, CD-Player, MP3-Player usw. auf. Die Verbindung zwischen dem Hörhilfegerät und dem externen Gerät erfolgt dabei entweder drahtlos oder drahtgebunden. Üblicherweise wird das betreffende Hörhilfegerät zum Audio-Empfang mit einem so genannten "Audio-Schuh" verbunden. Ausgehend von dem Audio-Schuh kann dann ein Draht zu dem externen Gerät führen. Es sind aber auch Audio-Schuhe bekannt, die eine Sende- und Empfangseinheit zur drahtlosen Datenübertragung zwischen dem Hörhilfegerät und einem externen Gerät umfassen. Derartige Drahtlos-Systeme werden beispielsweise auch in Schulungsräumen für Schwerhörige eingesetzt und sind unter der Bezeichnung "MLX" bekannt.Hearing aids usually have an audio input for connection to external devices such as radio, television, CD players, MP3 players, etc. The connection between the hearing aid and the external device is either wireless or wired.

Hörhilfegerätesysteme zur binauralen Versorgung eines Schwerhörigen werden zum Audio-Empfang häufig unsymmetrisch betrieben. Dabei wird lediglich eines der beiden Hörhilfegeräte mit der Audio-Signalquelle verbunden. In dieser Betriebsweise ist die Angleichung von Einstellungen der beiden Hörhilfegeräte des Hörhilfegerätesystems unzweckmäßig.Hearing aid systems for the binaural care of a deaf person are often operated asymmetrically for audio reception. Only one of the two hearing aids is connected to the audio signal source. In this mode of operation, the adjustment of settings of the two hearing aid devices of the hearing aid system is impractical.
Aufgabe der vorliegenden Erfindung ist es, eine bezüglich ihrer Einstellungen sinnvolle Kopplung zweier Hörhilfegeräte eines binauralen Hörhilfegerätesystems beim Audio-Empfang zu schaffen.Object of the present invention is to provide a meaningful in terms of their settings coupling two hearing aids of a binaural hearing aid system in audio reception.
Diese Aufgabe wird bei einem Hörhilfegerätesystem mit zwei am Kopf tragbaren Hörhilfegeräten zur binauralen Versorgung eines Hörhilfegeräteträgers, wobei die Hörhilfegeräte jeweils einen Eingangswandler zur Aufnahme eines Eingangssignals und Wandlung in ein elektrisches Signal, eine Signalverarbeitungseinheit zur Verarbeitung und frequenzabhängigen Verstärkung des elektrischen Signals und einen Ausgangswandler zur Wandlung des verarbeiteten Signals in ein von dem Hörhilfegeräteträger als akustisches Signal wahrnehmbares Signal umfassen, wobei bei den Hörhilfegeräten Parameter zur Steuerung der Signalverarbeitung in den Signalverarbeitungseinheiten einstellbar sind zur Anpassung der Signalverarbeitung an unterschiedliche Hörsituationen und wobei zwischen den beiden Hörhilfegeräten Steuersignale übertragbar sind zur Anpassung der in einem Hörhilfegerät eingestellten Parameter an die in dem anderen Hörhilfegerät eingestellten Parameter, dadurch gelöst, dass in einer Hörsituation für "Audio-Empfang" die Anpassung der eingestellten Parameter zwischen den beiden Hörhilfegeräten zumindest teilweise unterbunden ist.This object is achieved in a hearing aid device system with two head-worn hearing aids for the binaural supply of a hearing aid wearer, the hearing aid each having an input transducer for receiving an input signal and conversion into an electrical signal, a signal processing unit for processing and frequency-dependent amplification of the electrical signal and an output transducer for converting the processed signal into a perceptible by the hearing aid wearer signal as an audible signal, wherein the hearing aid parameters for controlling the signal processing in the signal processing units are adjustable to adapt the signal processing to different auditory situations and whereby control signals can be transmitted between the two hearing aid devices for adapting the parameters set in a hearing aid device to the parameters set in the other hearing aid device, in that in a hearing situation for "audio reception" the adjustment of the set parameters between the two hearing aids is at least partially prevented is.
Ferner wird die Aufgabe gelöst durch ein Verfahren zum Betrieb eines Hörhilfegerätesystems mit zwei am Kopf tragbaren Hörhilfegeräten zur binauralen Versorgung eines Hörhilfegeräteträgers, wobei die Hörhilfegeräte jeweils einen Eingangswandler zur Aufnahme eines Eingangssignals und Wandlung in ein elektrisches Signal, eine Signalverarbeitungseinheit zur Verarbeitung und frequenzabhängigen Verstärkung des elektrischen Signals und einen Ausgangswandler zur Wandlung des verarbeiteten Signals in ein von dem Hörhilfegeräteträger als akustisches Signal wahrnehmbares Signal umfassen, wobei bei den Hörhilfegeräten Parameter zur Steuerung der Signalverarbeitung in den Signalverarbeitungseinheiten einstellbar sind zur Anpassung der Signalverarbeitung an unterschiedliche Hörsituationen und wobei zwischen den beiden Hörhilfegeräten Steuersignale übertragbar sind zur Anpassung der in einem Hörhilfegerät eingestellten Parameter an die in dem anderen Hörhilfegerät eingestellten Parameter, mit folgenden Schritten:
- Anpassung der Parameter an eine Hörsituation für "Audio-Empfang" bei wenigstens einem der beiden Hörhilfegeräte,
- zumindest teilweises Unterbinden der Anpassung der eingestellten Parameter zwischen den beiden Hörhilfegeräten.
- Adaptation of the parameters to a hearing situation for "audio reception" in at least one of the two hearing aids,
- at least partially inhibiting the adaptation of the set parameters between the two hearing aids.
Bei einem Hörhilfegerät wird mittels eines Eingangswandlers ein Eingangssignal aufgenommen und in ein elektrisches Eingangssignal überführt. Üblicherweise dient als Eingangswandler wenigstens ein Mikrofon, welches ein akustisches Eingangssignal aufnimmt. Moderne Hörhilfegeräte umfassen häufig ein Mikrofonsystem mit mehreren Mikrofonen, um einen von der Einfallsrichtung akustischer Signale abhängigen Empfang, eine Richtcharakteristik, zu erreichen. Die Eingangswandler können jedoch auch eine Telefonspule oder eine Antenne umfassen zur Aufnahme elektromagnetischer Eingangssignale. Die durch den Eingangswandler in elektrische Eingangssignale gewandelten Eingangssignale werden zur Weiterverarbeitung und Verstärkung einer Signalverarbeitungseinheit zugeführt. Die Weiterverarbeitung und Verstärkung erfolgt zum Ausgleich des individuellen Hörverlustes eines Hörhilfegeräteträgers in der Regel in Abhängigkeit der Signalfrequenz. Die Signalverarbeitungseinheit gibt ein elektrisches Ausgangssignal ab, welches über einen Ausgangswandler dem Gehör des Hörhilfegeräteträgers zugeführt wird, so dass dieser das Ausgangssignal als akustisches Signal wahrnimmt. Als Ausgangswandler werden üblicherweise Hörer verwendet, die ein akustisches Ausgangssignal erzeugen. Es sind jedoch auch Ausgangswandler zur Erzeugung mechanischer Schwingungen bekannt, die direkt bestimmte Teile des Gehörs, wie beispielsweise die Gehörknöchelchen zu Schwingungen anregen. Weiterhin sind Ausgangswandler bekannt, die direkt Nervenzellen des Gehörs stimulieren.In a hearing aid, an input signal is recorded by means of an input transducer and converted into an electrical input signal. Usually serves as an input transducer at least one microphone which receives an acoustic input signal. Modern hearing aids often include a microphone system with a plurality of microphones to a dependent of the direction of incidence acoustic signals reception, a Directional characteristic to achieve. However, the input transducers may also include a telecoil or antenna for receiving electromagnetic input signals. The input signals converted by the input transducer into electrical input signals are fed to a signal processing unit for further processing and amplification. The further processing and amplification takes place to compensate for the individual hearing loss of a hearing aid wearer, as a rule, as a function of the signal frequency. The signal processing unit outputs an electrical output signal, which is fed via an output transducer to the hearing of the hearing aid wearer, so that the latter perceives the output signal as an acoustic signal. As output transducers usually listeners are used, which generate an acoustic output signal. However, output transducers for generating mechanical vibrations are also known, which directly excite certain parts of the ear, such as the ossicles, to vibrate.

Hörhilfegeräte sind in der Regel durch unterschiedliche Betriebsarten (Hörprogramme) auf unterschiedliche Hörsituationen einstellbar. Derartige Hörsituationen sind z.B. "ruhige Umgebung", "Fernsehen", "Gespräch in Störlärm" usw. Eine weitere Hörsituation ist der Audio-Empfang bei der das Hörhilfegerät über eine elektrische oder elektromagnetische Verbindung direkt mit einer Audio-Signalquelle verbunden ist. Gemäß der Erfindung wird bei einem Hörhilfegerätesystem mit zwei Hörhilfegeräten zur binauralen Versorgung eines Hörhilfegeräteträgers, bei dem eine automatische Kopplung von Einstellungen bei den beiden Hörhilfegeräten vorgesehen ist, die Kopplung in der Hörsituation "Audio-Empfang" zumindest weitgehend unterbrochen. Das heißt, manuelle Einstellungen an einem der beiden Hörhilfegeräte oder automatisch durchgeführte Parameteränderungen haben keine Auswirkungen mehr auf das andere Hörhilfegerät.Hearing aids are usually by different modes (hearing programs) adjustable to different listening situations. Such auditory situations are, for example, "quiet environment", "television", "conversation in noise", etc. Another hearing situation is the audio reception in which the hearing aid is connected via an electrical or electromagnetic connection directly to an audio signal source. According to the invention, in a hearing aid device system with two hearing aids for the binaural supply of a hearing aid wearer, in which an automatic coupling of settings in the two hearing aids is provided, the coupling in the auditory situation "audio reception" is at least largely interrupted. This means that manual settings on one of the two hearing aids or automatically performed parameter changes no longer affect the other hearing aid.
Ist wenigstens eines der beiden Hörhilfegeräte mit einer Audio-Signalquelle verbunden, so befindet sich das Hörhilfegerätesystem in der Hörsituation "Audio-Empfang" und das betreffende Hörhilfegerät ist (manuell oder automatisch) in eine an diese Hörsituation angepasste Betriebsart geschaltet. Es befindet sich somit in einem Modus für "aktiven Audio-Empfang" (= aktiver Audio-Modus). Ist lediglich eines der beiden Hörhilfegeräte mit der Audio-Signalquelle verbunden, so wird das zweite Hörhilfegerät des Hörhilfegerätesystems, welches nicht mit der Audio-Signalquelle verbunden ist, vorzugsweise ebenfalls durch entsprechende Parametereinstellungen an diese besondere Hörsituation angepasst. Es wird in einen speziellen Modus für diesen "passiven Audio-Empfang" (= passiver Audio-Modus) überführt. Vorzugsweise sendet ein Hörhilfegerät, das in den aktiven Audio-Modus versetzt wird, ein Steuersignal an das zweite Hörhilfegerät und versetzt dieses damit automatisch in den passiven Audio-Modus, sofern sich das zweite Hörhilfegerät nicht ebenfalls im aktiven Audio-Modus befindet.If at least one of the two hearing aid devices is connected to an audio signal source, then the hearing aid system is in the "audio reception" hearing situation and the relevant hearing aid device is switched (manually or automatically) into an operating mode adapted to this hearing situation. It is thus in a mode for "active audio reception" (= active audio mode). If only one of the two hearing aids is connected to the audio signal source, the second hearing aid of the hearing aid system, which is not connected to the audio signal source, preferably also adapted by appropriate parameter settings to this particular hearing situation. It is transferred to a special mode for this "passive audio reception" (= passive audio mode). Preferably, a hearing aid, which is placed in the active audio mode sends a control signal to the second hearing aid and thus puts this automatically in the passive audio mode, if the second hearing aid is not also in the active audio mode.
Die speziellen Einstellungen des Hörhilfegerätes im aktiven oder passiven Audio-Modus können vorzugsweise bei der Anpassung des Hörhilfegerätes durch einen Hörgeräte-Akustiker eingestellt werden. Im passiven Audio-Modus kann dadurch als Eingangssignal des betreffenden Hörhilfegerätes die Signalquelle verwendet werden, die dem Wunsch des Hörhilfegeräteträgers entspricht. Naheliegend ist das Mikrofonsignal, um Außengeräusche wahrnehmen zu können, oder auch eine Stummschaltung des Hörhilfegerätes. Außer dem Überführen des einen Hörhilfegerätes in den passiven Audio-Modus durch das Hörhilfegerät mit Audio-Empfang ist die wechselseitige Steuerung von Einstellparametern bei dem binauralen Hörhilfegerätesystem zumindest weitgehend aufgehoben. Ist bei beiden Hörhilfegeräten ein Audio-Empfang vorgesehen, so erfolgt bei dieser Betriebsweise vorzugsweise überhaupt keine wechselseitige Beeinflussung mehr.The special settings of the hearing aid device in the active or passive audio mode can preferably be adjusted during the adaptation of the hearing aid by a hearing aid acoustician. In the passive audio mode, the signal source corresponding to the request of the hearing aid wearer can thereby be used as the input signal of the relevant hearing aid device. The microphone signal is obvious in order to be able to perceive outside noise, or also to mute the hearing aid device. Apart from the transfer of a hearing aid in the passive audio mode by the hearing aid with audio reception, the mutual control of setting parameters in the binaural hearing aid system is at least largely eliminated. If an audio reception is provided in both hearing aid devices, preferably no interaction at all takes place in this mode of operation at all.
Erfolgt bei einem Hörhilfegerätesystem gemäß der Erfindung bei einem der Hörhilfegeräte eine manuelle Betätigung eines Bedienelementes durch den Benutzer, so bewirkt dies die gewünschte Einstellung bei diesem Hörhilfegerät. Dadurch ist z.B. eine von der Einstellung des anderen Hörhilfegerätes unabhängige Lautstärke-Einstellung möglich. Auf diese Weise kann die Balance zwischen den Hörhilfegeräten verändert werden.If, in the case of a hearing aid device system according to the invention, manual actuation of a control element by the user occurs in one of the hearing aid devices, this causes the desired setting in this hearing aid device. Thereby, e.g. an independent of the setting of the other hearing aid volume setting possible. In this way, the balance between the hearing aids can be changed.
Wird in das Hörhilfegerätesystem eine Fernbedienung mit einbezogen, so kann sich deren Bedienung auf beide Hörhilfegeräte auswirken. Beispielsweise kann eine Lautstärkenanpassung zu einer relativen Veränderung der Lautstärkeneinstellung beider Hörhilfegeräte führen, wobei die eingestellte Balance wegen der aufgehobenen Absolutwert-Kopplung erhalten bleibt. Im Unterschied hierzu führt eine mittels der Fernbedienung durchgeführte Programmumschaltung vorzugsweise lediglich zu einer Anpassung des Hörhilfegerätes im Audio-Modus an unterschiedliche Signalquellen, z.B. reiner Audio-Empfang oder Mischbetrieb "Audio-Empfang" und "Mikrofon-Empfang". Ein Hörhilfegerät im passiven Audio-Modus ist von einer derartigen Programmumschaltung dann nicht betroffen.If a remote control is included in the hearing aid system, their operation may affect both hearing aids. For example, a volume adjustment lead to a relative change in the volume setting of both hearing aids, the set balance is maintained because of the canceled absolute value coupling. In contrast to this, a program changeover carried out by means of the remote control preferably only leads to an adaptation of the hearing aid device in the audio mode to different signal sources, e.g. pure audio reception or mixed operation "audio reception" and "microphone reception". A hearing aid in the passive audio mode is then not affected by such a program switch.
Wird bei einem Hörhilfegerätesystem gemäß der Erfindung der Audio-Empfang beendet, so dass keines der beiden Hörhilfegeräte mehr mit einer Audio-Signalquelle verbunden ist, so kehrt das Hörhilfegerätesystem gemäß der Erfindung vorzugsweise zu den die Hörhilfegeräte betreffenden Einstellungen zurück, die es vor Aufnahme des Audio-Betriebs hatte. Dabei gibt bei einer ungleichen Lautstärkeeinstellung (Balance) das ehemals im aktiven Audio-Modus betriebene Hörhilfegerät die Lautstärkeeinstellung vor und das zweite Hörhilfegerät wird bei einer erforderlichen Anpassung der Lautstärke langsam an diese Einstellung angepasst ("Fading").If, in a hearing aid device system according to the invention, the audio reception is ended, so that neither of the two hearing aids is more connected to an audio signal source, the hearing aid system according to the invention preferably returns to the settings concerning the hearing aids, which it before recording the audio Operation had. In the case of an unequal volume setting (balance), the hearing aid device formerly operated in the active audio mode presets the volume setting, and the second hearing aid device is slowly adapted to this setting ("fading") if the volume is required.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert. Dabei zeigt die Figur ein Hörhilfegerätesystem mit einem hinter dem linken Ohr tragbaren Hörhilfegerät 1 und einem hinter dem rechten Ohr tragbaren Hörhilfegerät 2 zur binauralen Versorgung eines Hörhilfegeräteträgers. Bei beiden Hörhilfegeräten 1 und 2 dient ein Mikrofon 10 bzw. 14 zur Aufnahme eines akustischen Eingangssignals und Wandlung in ein elektrisches Signal. Dieses wird jeweils in einer Signalverarbeitungseinheit 11 bzw. 15 weiterverarbeitet und in Abhängigkeit der Signalfrequenz verstärkt zum Ausgleich des individuellen Hörverlustes des Hörhilfegeräteträgers. Das verarbeitete und verstärkte Signal wird jeweils mittels eines Hörers 12 bzw. 16 in ein akustisches Signal zurück gewandelt und dem Gehör des Hörhilfegeräteträgers über die Schallkanäle 13 bzw. 17 und daran anschließende Schallschläuche (nicht dargestellt) zugeführt.The invention will be explained in more detail with reference to an embodiment. The figure shows a hearing aid system with a
Bei den beiden Hörhilfegeräten ist eine drahtlose Kopplung vorgesehen, so dass automatisch oder manuell durchgeführte Veränderungen von Einstellungen bei einem der beiden Hörhilfegeräte Auswirkungen auf das jeweils andere Hörhilfegerät zeigen. Wird z.B. durch Bedienen des Lautstärkestellers 4 oder durch Betätigung der Programmwahltaste 3 das Hörhilfegerät 1 manuell bedient, so wird auch bei dem Hörhilfegerät 2 die Lautstärke verändert oder das aktive Hörprogramm umgeschaltet, ohne hierfür die Programmwahltaste 5 bzw. den Lautstärkesteller 6 bedienen zu müssen.In the two hearing aids wireless coupling is provided so that automatically or manually performed changes in settings in one of the two hearing aids show effects on the other hearing aid. If e.g. operated by the
Bei der in der Figur gezeigten Betriebsweise befindet sich das Hörhilfegerätesystem im Audio-Modus, da wenigstens eines der Hörhilfegeräte (Hörhilfegerät 1) mit einem Audio-Schuh 7 verbunden ist. Im Ausführungsbeispiel ist dieser an das untere Ende des Hörhilfegerätes 1 aufgesteckt. Der Audio-Schuh 7 im Ausführungsbeispiel umfasst eine Empfangseinheit zum drahtlosen Empfang eines von einer Audio-Signalquelle ausgehenden elektromagnetischen Signals. Die Audio-Signalquelle ist im Ausführungsbeispiel als CD-Player 8 mit einem Sender ausgeführt. In dieser speziellen Betriebsart hat eine Betätigung der Bedienelemente 3 oder 4 keine Auswirkungen auf das Hörhilfegerät 2. Umgekehrt beeinflusst eine Betätigung der Bedienelemente 5 oder 6 an dem Hörhilfegerät 2 das Hörhilfegerät 1 nicht.In the mode of operation shown in the figure, the hearing aid device system is in the audio mode, since at least one of the hearing aid devices (hearing aid device 1) is connected to an
Beim Aufstecken des Audio-Schuhs 7 auf das Hörhilfegerät 1 wird dieses in den aktiven Audio-Modus geschaltet. Daraufhin sendet das Hörhilfegerät 1 ein Signal an das Hörhilfegerät 2, das nicht mit einem Audio-Schuh verbunden ist und deshalb in dem passiven Audio-Modus versetzt wird. Im passiven Audio-Modus wird das Hörhilfegerät 2 gemäß dem bei der Programmierung des Hörhilfegerätes 2 festgelegten Vorgaben des Benutzers eingestellt, z.B. auf Mikrofonempfang oder Stummschaltung. Außer der Überführung des Hörhilfegerätes 2 in den passiven Audio-Modus durch das Hörhilfegerät 1 erfolgt während des Audio-Betriebes keine weitere gegenseitige Beeinflussung der Hörhilfegeräte 1 und 2. Nach Beendigung des Audio-Modus, d.h. durch Lösen des Audio-Schuhs 7 von dem Hörhilfegerät 1, fällt das Hörhilfegerät 1 wieder zurück in den ursprünglichen Betriebsmodus in dem es sich vor Beginn des Audio-Modus befunden hatte. Weiterhin wird von dem Hörhilfegerät 1 ein Signal an das Hörhilfegerät 2 übermittelt, welches auch diesem das Ende des Audio-Betriebes anzeigt und es in den ursprünglichen Betriebsmodus zurückversetzt.When attaching the
Das Hörhilfegerätesystem gemäß dem Ausführungsbeispiel umfasst weiterhin eine Fernbedienung 9. Diese weist die mit 1 bis 4 beschrifteten Programmtasten zur Programmwahl sowie eine Schaltwippe 18 zur Lautstärkeneinstellung auf. Im Audio-Modus wirkt sich eine Programmumschaltung durch Betätigung einer der mit 1 bis 4 beschrifteten Tasten lediglich auf das Hörhilfegerät 1 aus. Z.B. kann dadurch ein reiner Audio-Empfang oder ein Mischbetrieb mit Audio- und Mikrofon-Empfang eingestellt werden. Eine Veränderung der Lautstärkeneinstellung durch Betätigung der Schaltwippe 18 wirkt sich hingegen auf beide Hörhilfegeräte 1 und 2 aus, indem bei beiden Hörhilfegeräten 1 und 2 die Lautstärke um einen bestimmten Wert angehoben oder abgesenkt wird.The hearing aid system according to the embodiment further comprises a
Durch die Erfindung wird bei einem Hörhilfegerätesystem zur binauralen Versorgung eines Hörhilfegeräteträgers auch im Audio-Modus eine sinnvolle Einstellung der Hörhilfegeräte bei direkter Bedienung eines der beiden Hörhilfegeräte oder bei Bedienung des Hörhilfegerätesystems mittels einer Fernbedienung erreicht. Die Fernbedienung bleibt auch in Verbindung mit einem binauralen Hörhilfegerätesystem mit gekoppelten Einstellungen unter ein- oder beidseitiger Verwendung eines Audio-Schuhs sinnvoll einsetzbar. Das Hörhilfegerätesystem passt sich automatisch den Vorlieben des Hörhilfegeräteträgers in dieser speziellen Hörsituation an.By means of the invention, in a hearing aid system for binaurally supplying a hearing aid wearer, a meaningful adjustment of the hearing aid devices is also achieved in audio mode by direct operation of one of the two hearing aid devices or by operation of the hearing aid system by means of a remote control. The remote control also remains useful in connection with a binaural hearing aid system with coupled settings with one or two-sided use of an audio shoe. The hearing aid system automatically adapts to the preferences of the hearing aid wearer in this particular hearing situation.
