Aufgabe der vorliegenden Erfindung ist es, ein Hörgerätesystem der eingangs genannten Art bezüglich seiner Hörhilfegeräte zu vereinfachen sowie ein Verfahren zum Betrieb eines derartigen Hörgerätesystems anzugeben.The object of the present invention is a hearing aid system of the type mentioned above with regard to his hearing aids to simplify and a procedure for operating a to specify such hearing aid system.
Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß zumindest von einem Bedienelement zum Anpassen des einen Hörhilfegerätes erzeugte Steuersignale auf das zweite Hörhilfegerät übertragbar sind und eine simultane Anpassung der beiden Hörhilfegeräte durch diese Steuersignale und die hörgeräteeigenen Signalverarbeitungseinheiten vorgesehen ist. Gemäß der Erfindung wird damit eine wesentliche Vereinfachung in der Bedienung und/oder der Ausstattung des Hörgerätesystems erreicht.According to the invention, this object is achieved in that at least one control element to adapt one Hearing aid device generates control signals to the second hearing aid device are transferable and a simultaneous adaptation of the both hearing aids through these control signals and the hearing aid's own Signal processing units is provided. According to the invention, this becomes a significant simplification in the operation and / or equipment of the hearing aid system reached.
Bei einem erfindungsgemäßen Verfahren zum Betrieb eines Hörgerätesystems der eingangs genannten Art werden die von den Bedienelementen zum Anpassen des einen Hörhilfegerätes erzeugten Steuersignale auf das zweite Hörhilfegerat übertragen und die beiden Hörhilfegeräte sind durch diese Steuersignale und die hörgeräteeigenen Signalverarbeitungseinheiten simultan anpaßbar.In a method according to the invention for operating a hearing aid system of the type mentioned at the outset Control elements for adapting the one hearing aid device Control signals transmitted to the second hearing aid and the two hearing aids are through these control signals and the hearing aid's own signal processing units simultaneously customizable.
Bekannte Bedienelemente bei Hörhilfegeräten sind beispielsweise; Ein-Ausschalter, Eingangs-Wahlschalter für Mikrofon oder Hörspule, Verstärkungssteller, Klangblende, Mikrofonschalter oder Programmwahlschalter. Die Bedienelemente ermöglichen die Anpassung der Hörhilfegeräte an den Bedarfsfall. Sie können schrittweise (z.B. Schalter) oder kontinuierlich (z.B. Stellerwiderstände) verstellbar sein.Known controls for hearing aids are for example; On-off switch, input selector switch for microphone or audio coil, gain control, sound panel, microphone switch or program selector. The controls allow the adaptation of the hearing aids to the need. They can be incremental (e.g. switches) or continuous (e.g. actuator resistances).
Die Erfindung realisiert die Funktion einer Fernbedienung, vermeidet aber deren Nachteile, da die Sendeeinheit mit im Hörhilfegerät integriert ist. Die Erfindung hat den Vorteil, daß keine separate Fernbedienung mitgeführt werden muß. Zur Anpassung der beiden Hörhilfegeräte genügt es, eines der beiden Hörhilfegeräte zu bedienen. Dies ist insbesondere beim Umschalten in ein anderes Hörprogramm von Vorteil. Bei herkömmlichen Hörgerätesystemen kann es vorkommen, daß eines der beiden Geräte im falschen Hörprogramm betrieben wird. Besonders nachteilig wirkt sich dies aus, wenn z.B. das eine Gerät mit Richtmikrofon und das andere omnidirektional betrieben wird. Totale Desorientierung könnte die Folge sein.The invention realizes the function of a remote control, but avoids their disadvantages, since the transmitter unit with im Hearing aid is integrated. The invention has the advantage that no separate remote control has to be carried. For It is sufficient to adapt the two hearing aids to one of the two To operate hearing aids. This is particularly the case with Switching to another hearing program is an advantage. With conventional Hearing aid systems it can happen that one of the both devices are operated in the wrong hearing program. Especially This has a disadvantageous effect if, e.g. the one Device with directional microphone and the other operated omnidirectionally becomes. This could result in total disorientation.

Nach einer Ausführungsform der Erfindung umfaßt das Hörgerätesystem zwei Hörhilfegeräte, die hinsichtlich ihrer Bedienelemente übereinstimmen und sich von herkömmlichen Hörhilfegeräten dadurch unterscheiden, daß zumindest bei einem der Bedienelemente eine Übertragung der durch die Betätigung erzeugten Steuersignale zum anderen Hörhilfegerät erfolgt. Dies hat den Vorteil, daß die Erfindung bei Hörhilfegeräten ohne Änderung der heute üblichen Gehäuse angewandt werden kann. Wird an einem der beiden Hörhilfegeräte ein Bedienelement betätigt, so werden nach der Erfindung beide Hörhilfegeräte entsprechend angepaßt.According to one embodiment of the invention, the hearing aid system comprises two hearing aids regarding their controls match and differ from conventional hearing aids distinguish in that at least one of the controls a transmission of the by pressing generated control signals to the other hearing aid. This has the advantage that the invention in hearing aids can be used without changing the usual housing today can. Is a control on one of the two hearing aids actuated, both hearing aids are according to the invention adjusted accordingly.
Eine weitere Variante der Erfindung sieht vor, die Bedienelemente zumindest teilweise auf beide Hörhilfegeräte aufzuteilen. Dies hat zur Folge, daß damit nicht mehr jede Art von Bedienelementen an jedem der Hörhilfegeräte vorhanden ist und damit insgesamt weniger Platzbedarf für die Anbringung von Bedienelementen erforderlich ist, wodurch die verbleibenden Bedienelemente entsprechend größer ausgeführt oder, bei unveränderter Größe der Bedienelemente, die Gehäuse der Hörhilfegeräte entsprechend verkleinert werden können.Another variant of the invention provides the controls to be divided at least partially between the two hearing aids. The result of this is that not every type of Controls are present on each of the hearing aids and overall less space required for the attachment of Controls are required, leaving the remaining Controls are designed accordingly larger or, if unchanged Size of the controls, the housing of the hearing aids can be reduced accordingly.
Eine besonders bevorzugte Variante der Erfindung sieht vor, daß bei beiden Hörhilfegeräten je ein Lautstärkeregler vorhanden ist, bei dessen Betätigung es nicht zu einem Signalaustausch gemäß der Erfindung kommt, so daß sich die Verstärkung bei beiden Hörhilfegeräten separat einstellen läßt, was einer unterschiedlichen Hörschwäche der beiden Ohren eines Hörgeräteträgers Rechnung trägt. Weitere Bedienelemente wie beispielsweise der Eingangswahlschalter für Mikrofon oder Hörspule, der Klangregler oder der Programmwahlschalter sind gemäß der Erfindung auf beide Hörhilfegeräte verteilt. Die Betätigung eines der letztgenannten Bedienelemente führt damit zu einer simultanen Anpassung beider Hörhilfegeräte.A particularly preferred variant of the invention provides that a volume control is available for both hearing aids is no signal exchange when actuated comes according to the invention, so that the gain can be set separately for both hearing aids, what a different hearing loss of the two ears one Hearing aid wearer takes into account. Other controls such as the input selector switch for microphone or Hearing coil, tone control or program selector switch distributed to both hearing aids according to the invention. The Operation of one of the latter controls leads thus for a simultaneous adaptation of both hearing aids.
Eine weitere Ausführungsform der Erfindung sieht vor, alle Bedienelemente an nur einem der beiden Hörhilfegeräte anzubringen, was zu einer sehr kostengünstigen Variante führt und bei dem Hörhilfegerät ohne Bedienelemente eine sehr kleine Bauform ermöglicht.Another embodiment of the invention provides all Attach controls to only one of the two hearing aids, which leads to a very inexpensive variant and a very small one for the hearing aid without controls Design enables.
Eine weitere erfindungsgemäße Variante des Hörgerätesystems sieht vor, daß zumindest bei einigen der Bedienelemente die Wahlmöglichkeit besteht, ob bei einer Betätigung dieser Bedienelemente eine Anpassung des anderen Hörhilfegerätes erfolgt. Derartige Einstellungen können beispielsweise bei der Programmierung des Hörgerätesystems festgelegt werden. Dies erhöht die Zahl der Anwendungsmöglichkeiten für Hörgerätesysteme nach der Erfindung bei gleichzeitiger Reduzierung der Gerätevarianten. So kann beispielsweise nach der Erfindung ein und dasselbe Hörhilfegerät bei einem Hörgeräteträger mit beidseitig gleich ausgeprägter Gehörschwäche eingesetzt werden, der die Lautstärkeregelung nur an einem der beiden Hörhilfegeräte zu verändern wünscht und sich diese Veränderung dann auf beide Hörhilfegeräte gleichermaßen auswirkt. Des weiteren kann das gleiche Hörhilfegerät auch bei einem Hörgeräteträger mit unterschiedlich ausgeprägter Gehörschwäche eingesetzt werden, der die Lautstärke beider Geräte individuell anzupassen wünscht.Another variant of the hearing aid system according to the invention provides that at least some of the controls There is a choice of whether these controls are activated the other hearing aid is adapted. Such settings can, for example, at Programming of the hearing aid system can be set. This increases the number of possible uses for hearing aid systems according to the invention while reducing the Device variants. For example, according to the invention one and the same hearing aid with a hearing aid wearer hearing loss equally pronounced on both sides, the volume control only on one of the two Hearing aid wants to change and this change then affects both hearing aids equally. Furthermore, the same hearing aid can also be used for one Hearing aid wearers with varying degrees of hearing loss be used, the volume of both devices individually wishes to adjust.
Eine erfindungsgemäße Lösung der gestellten Aufgabe, ein Hörgerätesystem bezüglich seiner Hörhilfegeräte zu vereinfachen, ist ferner dadurch gekennzeichnet, daß nur eines der beiden Hörhilfegeräte Mittel zur Signalverarbeitung aufweist, welche vom Mikrofon dieses Hörhilfegerätes sowie vom Mikrofon des zweiten Hörhilfegerätes empfangene und an das erste Hörhilfegerät übertragene Audiosignale verarbeiten, und wobei verarbeitete Audiosignale dem eigenen Hörer bzw. nach einer Übertragung verarbeiteter Audiosignale an das zweite Hörhilfegerät diese dem Hörer des zweiten Hörghilfegerätes zuführbar sind. Gemäß der Erfindung sind bei einem solchen Hörgerätesystem Hörhilfegeräte mit vereinfachten Signalverarbeitungseinheiten verwendbar.An inventive solution to the problem, a hearing aid system to simplify its hearing aids, is further characterized in that only one of the two Hearing aid devices has means for signal processing, which from the microphone of this hearing aid and from the microphone of the second hearing aid received and to the first hearing aid Process transmitted audio signals, and being processed Audio signals to your own listener or after a transmission processed audio signals to the second hearing aid these can be fed to the listener of the second hearing aid device are. According to the invention are in such a hearing aid system Hearing aids with simplified signal processing units usable.
Die Verarbeitung der von den Mikrofonen beider Hörhilfegeräte aufgenommenen Audiosignale in nur einer Signalverarbeitungseinheit bietet außer der kleineren Baugröße eines der beiden Hörhilfegeräte noch weitere Vorteile. So lassen sich durch die gemeinsame Verarbeitung der von beiden Hörhilfegeräten aufgenommenen Audiosignale das räumliche Hören und die Unterdrückung von Störgeräuschen wesentlich verbessern. Darüber hinaus ist durch den Wegfall einer Signalverarbeitungseinheit in einer der Hörhilfegeräte auch eine Kostenersparnis möglich. Der äußere Aufbau des betreffenden Hörhilfegerätes kann entsprechend kleiner und leichter ausgeführt werden und auch der Stromverbrauch sinkt, wodurch die Kapazität und damit die Größe der Spannungsquelle entsprechend angepaßt werden kann.The processing of the microphones of both hearing aids recorded audio signals in only one signal processing unit offers one of the two in addition to the smaller size Hearing aids have other advantages. So let through the joint processing of both hearing aids audio signals recorded spatial hearing and suppression of noise significantly improve. About that is also due to the elimination of a signal processing unit Cost savings are also possible in one of the hearing aids. The outer structure of the hearing aid in question can correspondingly smaller and lighter and also run the power consumption decreases, which increases the capacity and thus the Size of the voltage source can be adjusted accordingly.
Nach einer weiteren Variante der Erfindung erfolgt für die von den jeweiligen Mikrofonen der Hörhilfegeräte empfangenen Audiosignale zunächst eine Signalvorverarbeitung, bevor sie einer gemeinsamen Signalverarbeitungseinheit zugeführt werden. Diese Signalvorverarbeitung umfaßt beispielsweise eine AD-Wandlung mit Bandpaßfilterung.According to a further variant of the invention, the received by the respective microphones of the hearing aids Audio signals first have a signal preprocessing before be supplied to a common signal processing unit. This signal preprocessing includes, for example AD conversion with bandpass filtering.
Entsprechend werden nach einer Ausführungsform die verarbeiteten Audiosignale des jeweiligen Hörhilfegerätes nachverarbeitet, bevor sie den Hörern zugeführt werden. Diese Signalnachverarbeitung umfaßt beispielsweise eine DA-Wandlung und Verstärkung.According to one embodiment, the processed ones Post-processed audio signals of the respective hearing aid, before they are delivered to the listeners. This signal post-processing includes, for example, a DA conversion and Reinforcement.
Der Wunsch nach möglichst kleinen Bauformen der Hörhilfegeräte läßt sich nach der Erfindung am besten dadurch realisieren, daß der überwiegende Teil der Bedienelemente des Hörgerätesystems nicht an dem Hörhilfegerät angeordnet ist, welches die Mittel zur Signalverarbeitung der von beiden Mikrofonen empfangenen Audiosignale aufweist. Da bei diesem Hörhilfegerät die verbleibende Signalverarbeitungseinheit gegenüber der Signalverarbeitungseinheit des anderen Hörhilfegerätes wesentlich kleiner und leistungsschwächer ausgeführt ist, wird dafür weniger Platz beansprucht. Als weitere Folge ist auch der Energieverbrauch dieses Hörhilfegerätes wesentlich reduziert, womit die Spannungsquelle entsprechend kleiner dimensioniert werden kann. Durch diese Effekte wird der erhöhte Platzbedarf für die größere Anzahl an Bedienelementen an diesem Hörhilfegerät kompensiert. Insgesamt läßt sich somit die Bauform beider Hörhilfegeräte verkleinern.The desire for the smallest possible construction of the hearing aids can best be realized according to the invention by that the majority of the controls of the hearing aid system is not arranged on the hearing aid, which the means for signal processing from both microphones received audio signals. Because with this hearing aid the remaining signal processing unit opposite the signal processing unit of the other hearing aid is much smaller and less powerful, less space is required for this. As a further consequence the energy consumption of this hearing aid is also significant reduced, whereby the voltage source is dimensioned correspondingly smaller can be. These effects increase the Space required for the larger number of controls on this Hearing aid compensated. Overall, the Reduce the size of both hearing aids.
Zur Übertragung der Audio- und/oder Steuersignale zwischen den Hörhilfegeräten weisen diese entsprechende Mittel zum Senden und/oder Empfangen derartiger Signale auf. Es sind alle für die Übertragung üblichen Methoden denkbar. So sieht eine Variante der Erfindung eine drahtgebundene Übertragung und eine andere Variante eine drahltlose Übertragung, beispielsweise in Form elektromagnetischer Wellen, vor. Nach der Erfindung kann es sich bei den übertragenen Signalen sowohl um analoge als auch digitale Signale handeln. To transmit the audio and / or control signals between the hearing aids have appropriate means for this Sending and / or receiving such signals. There are all methods customary for transmission are conceivable. So look a variant of the invention a wired transmission and another variant is a wireless transmission, for example in the form of electromagnetic waves. After Invention can be both in the transmitted signals are analog as well as digital signals.
Besonders einfach und kostengünstig erfolgt nach der Erfindung der Austausch der Audio- und/oder Steuersignale über an jedem der Hörhilfegeräte befindliche Mittel zum Senden und/oder Empfangen dieser Signale in Verbindung mit je einer Telefonspule, wie sie bei üblichen Hörhilfegeräten zur induktiven Aufnahme magnetischer Nutzsignale bereits vorhanden ist. Damit wird der Aufwand an zusätzlichen Bauteilen zur Ausführung der Erfindung auf ein Minimum begrenzt. Zusätzlich zum Senden und/oder Empfangen der Audio- und/oder Steuersignale gemäß der Erfindung oder zum Übertragen von Nutzsignalen kann über die Telefonspulen auch die drahtlose Programmierung oder Fernbedienung der Hörhilfegeräte erfolgen.The invention is particularly simple and inexpensive the exchange of audio and / or control signals via on means of transmission for each of the hearing aids and / or receiving these signals in connection with one each Telephone coil, as used in conventional hearing aids for inductive Magnetic useful signals already recorded is. This means that the expense of additional components Execution of the invention limited to a minimum. In addition for sending and / or receiving the audio and / or control signals according to the invention or for the transmission of useful signals can also use the telephone coils for wireless programming or remote control of the hearing aids.

Das durch die Betätigung des Bedienelementes 5' erzeugte Steuersignal 7' wird zur Signalverarbeitungseinheit 3' sowie zur Sende- und/oder Empfangseinheit 9' geleitet. Über die Sende- und/oder Empfangseinheit 9' und die Telefonspule 13' wird das Steuersignal 7' vom Hörhilfegerät 1' auf das Hörhilfegerät 1 übertragen. Dort wird es über die Telefonspule 13 und die Sende- und/oder Empfangseinheit 9 als Steuersignal 14 der Signalverarbeitungseinheit 3 zugeführt. Entsprechend wird das Steuersignal 7 des Hörgerätes 1 über die Sende- und/oder Empfangseinheit 9 und die Telefonspule 13 an das Hörhilfegerät 1' übertragen und dort über die Telefonspule 13' und die Sende- und/oder Empfangseinheit 9' als Steuersignal 14' der Signalverarbeitungseinheit 3' zugeführt.While in the hearing aid 1, the control element 5 as a program selection switch serves and has a key switch 12, the control element 5 'in the hearing aid 1' serves as an input selector switch for microphone or audio coil and points to this a slide switch 11 'with two stable end positions on. That generated by operating the control element 5 ' Control signal 7 'becomes the signal processing unit 3' and routed to the transmitting and / or receiving unit 9 '. About the Transmitting and / or receiving unit 9 'and the telephone coil 13' the control signal 7 'from the hearing aid 1' to the hearing aid 1 transferred. There it is over the telephone coil 13 and the transmitting and / or receiving unit 9 as control signal 14 fed to the signal processing unit 3.
