Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum individuellen Einstellen eines Hörhilfegerätes für einen Hörgeräteträger.The present invention relates to a method and a device for individually setting a hearing aid device for a hearing aid wearer.

Technischer Fortschritt und neue wissenschaftliche Erkenntnisse führen zu einer ständigen Weiterentwicklung von Hörgeräten. Dies betrifft sowohl die eingesetzten Signalverarbeitungsalgorithmen als auch die aus den audiometrischen Daten berechneten individuellen Parametersätze für Hörgeräteeinstellungen. In Neugeräten sind diese Weiterentwicklungen vielfach berücksichtigt.Technological progress and new scientific findings lead to a continuous development of hearing aids. This applies both to the signal processing algorithms used and to the individual parameter sets for hearing aid settings calculated from the audiometric data. In new devices these developments are often considered.

Ein Schwerhöriger gewöhnt sich jedoch durch das ständige Tragen eines Hörsystems an die Übertragungseigenschaften und somit beispielsweise an den Klang dieses Hörsystems. Benötigt er beispielsweise wegen einer Hörverschlechterung ein neues Gerät, empfindet er oftmals den ungewohnten Klang als fremd und lehnt ein neues Hörsystem ab. Diese Ablehnung kommt besonders bei modernen Hörsystemen vor, da bei diesen aufgrund der Fortschritte in der Digitaltechnik häufig sehr glatte Frequenzgänge realisiert werden können. Aus diesem Grund wird bei einer Nachversorgung oft anstelle eines modernen Hörsystems der gleiche Typ des bereits getragenen Hörsystems verwendet. Für den Schwerhörigen tritt dadurch keine Verbesserung ein und er profitiert nicht von einer Weiterentwicklung der Hörsysteme.However, a hearing-impaired person becomes accustomed to the transmission characteristics of the hearing aid and thus to the sound of this hearing system, for example. For example, if he needs a new device because of hearing loss, he often feels the unfamiliar sound as foreign and rejects a new hearing system. This rejection is particularly prevalent in modern hearing systems, as these are often due to the advances in digital technology very smooth frequency responses can be realized. For this reason, a follow-up care often used instead of a modern hearing system, the same type of already worn hearing aid. This does not improve the hearing-impaired and does not benefit from the further development of hearing systems.

Waren Hörgeräteträger dennoch bereit, ein neues Gerät einzusetzen, so versuchten die Hörgeräteakustiker bislang per Hand die Akustik des alten Gerätes mit dem neuen nachzuempfinden, um den Umstieg zu erleichtern. Da moderne Hörhilfegeräte extrem komplex sind, ist es auf diese Weise nicht möglich, die optimale Einstellung zu finden, bei der einerseits der Klang des alten Gerätes nachempfunden wird und andererseits die Vorteile des neuen Gerätes noch zur Geltung kommen.If hearing aid wearers were nevertheless willing to use a new device, the hearing care professionals have so far tried by hand to recreate the acoustics of the old device with the new one in order to facilitate the changeover. Since modern hearing aids are extremely complex, it is not possible in this way to find the optimum setting, on the one hand the sound the old device is modeled on the other hand, the benefits of the new device still come into their own.

Aus der EP 1453358 A1 ist es bekannt, bei der Versorgung mit einem Zweit- oder Folgegerät die Einstellungen des alten Hörhilfegerätes durch einen rechnergesteuerten Vorgang zu erfassen und bei der Anpassung des neuen Hörhilfegerätes in einer Ersteinstellung zu berücksichtigen. Die Neueinstellung ergibt sich dann aus audiometrischen Messungen, den Daten des bisherigen Gerätes und gegebenenfalls weiterer Daten. Der Klang des neuen Gerätes ist damit an das alte Gerät angenähert.From the EP 1453358 A1 It is known to detect the settings of the old hearing aid by a computer-controlled process in the supply of a second or follower device and to take into account in the adjustment of the new hearing aid in a first setting. The new setting then results from audiometric measurements, the data of the previous device and possibly other data. The sound of the new device is thus approximated to the old device.

Dabei ist es erforderlich, entweder die Daten des alten Hörhilfegerätes vorliegen zu haben, oder diese aus dem Hörhilfegerät auszulesen um sie interpretieren zu können. Alternativ können die Eigenschaften des alten Hörhilfegerätes auch gemessen werden. Dazu kann eine akustische Messvorrichtung verwendet werden, die jedoch hohe Anforderungen an die akustische Umgebung, die Prüfsignalquelle und den akustischen Messsensor stellt.It is necessary either to have the data from the old hearing aid device available, or to read it from the hearing aid to be able to interpret it. Alternatively, the characteristics of the old hearing aid can also be measured. For this purpose, an acoustic measuring device can be used, which however places high demands on the acoustic environment, the test signal source and the acoustic measuring sensor.

Aus der EP 1416764 A2 ist es bekannt, die Einstellungen eines bereits angepassten (alten) Hörgeräts anhand eines Prüfsignals zu ermitteln und ein anderes (neues) Hörgerät entsprechend einzustellen. Dabei wird der Hörer des neuen Hörgeräts akustisch an das Mikrofon des alten Hörgeräts angekoppelt und der Ausgang des Hörers des alten Hörgeräts wird von einem separaten Messmikrofon aufgezeichnet und ausgewertet.From the EP 1416764 A2 It is known to determine the settings of an already adapted (old) hearing aid based on a test signal and adjust another (new) hearing aid accordingly. The handset of the new hearing aid is acoustically coupled to the microphone of the old hearing aid and the output of the handset of the old hearing aid is recorded and evaluated by a separate measuring microphone.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, die Einstellung eines Hörhilfegerätes unter Berücksichtigung einer Einstellung eines beliebigen andern Hörhilfegerätes zu vereinfachen.The object of the present invention is therefore to simplify the setting of a hearing aid device, taking into account a setting of any other hearing aid device.

Die erfindungsgemäße Aufgabe wird durch das Verfahren des Anspruchs 1 und die Vorrichtung des Anspruchs 7 gelöst.The object of the invention is achieved by the method of claim 1 and the apparatus of claim 7.

Das Verfahren des Anspruchs 1 vereinfacht eine Analyse von Hörhilfegeräteeinstellungen eines ersten Hörhilfegerätes, indem zur Ermittlung der Eigenschaften des ersten Hörhilfegerätes ein zweites Hörhilfegerät genutzt wird. Dabei weisen das erste Hörhilfegerät und das zweite Hörhilfegeräte je einen akusto-elektrischen Wandler und einen elektro-akustischen Wandler auf. Das Verfahren weist den Schritt auf, den elektro-akustischen Wandlers des ersten Hörhilfegerätes mit dem akusto-elektrischen Wandlers des zweiten Hörhilfegerätes mit einem Koppelmittel akustisch zu koppeln. Unter akustisch gekoppelt ist hierbei zu verstehen, dass Schallwellen von dem elektro-akustischen Wandler des ersten Hörhilfegerätes zu dem akusto-elektrischen Wandler des zweiten Hörhilfegerätes auf vorbestimmte und vorhersagbare Weise gelangen können. Dies kann beispielsweise durch einen Raum erfolgen, der beide Wandler dicht umschließt. Dabei ist es auch denkbar, dass das erste und/oder zweite Hörhilfegerät mehrere akusto-elektrische Wandler aufweisen. In einem weiteren Schritt wird der akusto-elektrische Wandler des ersten Hörhilfegerätes mit einem akustischen Prüfsignal beschallt und ein akustisches Ausgangssignal des elektro-akustischen Wandlers des ersten Hörhilfegerätes mittels des akusto-elektrischen Wandlers des zweiten Hörhilfegerätes erfasst. Das erfasste akustische Signal kann von dem akusto-elektrischen Wandler des zweiten Hörhilfegerätes beispielsweise als analoges oder digitales elektrisches Signal bereitgestellt werden. Schließlich wird in einem Schritt das erfasste akustische Ausgangssignals ausgewertet. Die Auswertung kann beispielsweise durch Vergleich oder Verarbeitung mittels eines Algorithmus mit dem bekannten Prüfsignal erfolgen.The method of claim 1 simplifies an analysis of hearing aid device settings of a first hearing aid device by using a second hearing aid device to determine the characteristics of the first hearing aid device. In this case, the first hearing aid and the second hearing aid each have an acousto-electric converter and an electro-acoustic transducer. The method comprises the step of acoustically coupling the electro-acoustic transducer of the first hearing aid with the acousto-electrical transducer of the second hearing aid with a coupling agent. By acoustically coupled is meant that sound waves from the electro-acoustic transducer of the first hearing aid to the acousto-electric transducer of the second hearing aid can arrive in a predetermined and predictable way. This can be done, for example, through a room that tightly encloses both converters. It is also conceivable that the first and / or second hearing aid device have a plurality of acousto-electrical converter. In a further step, the acousto-electrical converter of the first hearing aid is sonicated with an acoustic test signal and detects an acoustic output signal of the electro-acoustic transducer of the first hearing aid by means of the acousto-electrical transducer of the second hearing aid. The detected acoustic signal can be provided by the acousto-electrical converter of the second hearing aid device, for example as an analog or digital electrical signal. Finally, in one step, the detected acoustic output signal is evaluated. The evaluation can be done for example by comparison or processing by means of an algorithm with the known test signal.

Das erfindungsgemäße Verfahren nützt auf vorteilhafte Weise den akusto-elektrischen Wandler bzw. das Mikrofon des zweiten Hörhilfegerätes als Messsensor, wodurch der apparative Aufwand für die Durchführung des Verfahrens reduziert werden kann.The method according to the invention advantageously utilizes the acousto-electrical converter or the microphone of the second hearing aid device as the measuring sensor, as a result of which the expenditure on apparatus for carrying out the method can be reduced.

Die Aufgabe wird mit Hilfe der erfindungsgemäßen Vorrichtung des Anspruchs 7 gelöst, die insbesondere zur Ausführung des Verfahrens ausgelegt ist. Die Vorrichtung zur Analyse einer Hörhilfegeräteeinstellung eines ersten Hörhilfegerätes mittels eines zweiten Hörhilfegerätes weist ein Koppelmittel zum akustischen Koppeln eines elektro-akustischen Wandlers eines ersten Hörhilfegerätes mit einem akusto-elektrischen Wandler eines zweiten Hörhilfegerätes auf. Das Koppelmittel ist dazu ausgelegt, dass Schallwellen von dem elektro-akustischen Wandler des ersten Hörhilfegerätes zu dem akusto-elektrischen Wandler des zweiten Hörhilfegerätes auf vorbestimmte und vorhersagbare Weise gelangen können. Dies kann beispielsweise durch einen Raum erfolgen, der beide Wandler dicht umschließt. Dabei ist es auch denkbar, dass das erste und/oder zweite Hörhilfegerät mehrere akusto-elektrische Wandler aufweisen. Weiterhin weist die Vorrichtung eine Analyseeinrichtung auf, welche dazu ausgelegt ist, ein Signal mit Informationen von dem akusto-elektrischen Wandler von dem zweiten Hörhilfegerät zu empfangen und zu analysieren. Die Verbindung kann beispielsweise durch eine elektrische Signalverbindung erfolgen, aber auch durch elektromagnetische Felder oder andere drahtlose Übertragungstechniken. Die Vorrichtung kann beispielsweise ausgelegt sein, das Signal mit Informationen von dem akusto-elektrischen Wandler mit einem bekannten Prüfsignal zu vergleichen oder mit einem Algorithmus zu verarbeiten. Dabei kann die Analyseeinrichtung verbindbar mit dem zweiten Hörhilfegerät ausgeführt sein, zum Beispiel als Teil einer Steuerung, oder auf als Teil oder Funktionalität der Signalverarbeitungseinrichtung des zweiten Hörhilfegerätes.The object is achieved by means of the device according to the invention of claim 7, which is designed in particular for carrying out the method. The device for analyzing a hearing aid setting of a first hearing aid by means of a second hearing aid has a coupling means for acoustically coupling an electro-acoustic transducer of a first hearing aid to an acousto-electrical transducer of a second hearing aid. The coupling means is designed so that sound waves can pass from the electro-acoustic transducer of the first hearing aid to the acousto-electrical transducer of the second hearing aid in a predetermined and predictable manner. This can be done, for example, through a room that tightly encloses both converters. It is also conceivable that the first and / or second hearing aid device have a plurality of acousto-electrical converter. Furthermore, the device has an analysis device which is designed to receive and analyze a signal with information from the acousto-electrical converter from the second hearing aid device. The connection can be made for example by an electrical signal connection, but also by electromagnetic fields or other wireless transmission techniques. The device can be designed, for example, to compare the signal with information from the acousto-electrical converter with a known test signal or to process it with an algorithm. In this case, the analysis device can be designed to be connectable to the second hearing aid device, for example as part of a controller, or as part of or functionality of the signal processing device of the second hearing aid device.

Die erfindungsgemäße Vorrichtung teilt die Vorteile des erfindungsgemäßen Verfahrens.The device according to the invention shares the advantages of the method according to the invention.

Weitere vorteilhafte Ausführungsformen sind in den Unteransprüchen angegeben.Further advantageous embodiments are specified in the subclaims.

In einer möglichen Ausführungsform des erfindungsgemäßen Verfahrens wird das akustische Prüfsignal von einem elektro-akustischen Wandler erzeugt.In one possible embodiment of the method according to the invention, the acoustic test signal is generated by an electro-acoustic transducer.

Ein elektroakustischer Wandler ermöglicht es auf einfache Weise, ein reproduzierbares Prüfsignal mit vorbestimmten Eigenschaften zu erzeugen.An electroacoustic transducer makes it possible in a simple manner to produce a reproducible test signal with predetermined properties.

In einer anderen denkbaren Ausführungsform des erfindungsgemäßen Verfahrens ist das akustische Prüfsignal ein Umgebungsgeräusch. Dabei weist das Verfahren weiterhin den Schritt auf, das Prüfsignal mittels eines akusto-elektrischen Referenzwandlers zu erfassen.In another conceivable embodiment of the method according to the invention, the acoustic test signal is an ambient noise. In this case, the method further comprises the step of detecting the test signal by means of an acousto-electrical reference transducer.

Indem ein Umgebungsgeräusch als Prüfsignal verwendet wird, ist es auf vorteilhafte Weise möglich, die Eigenschaften des ersten Hörhilfegerätes in für den Nutzer bevorzugten akustischen Umgebungen zu analysieren.By using ambient noise as a test signal, it is advantageously possible to analyze the characteristics of the first hearing aid in user-preferred acoustic environments.

In einer denkbaren Ausführungsform des erfindungsgemäßen Verfahrens erfolgt das Auswerten des erfassten akustischen Eingangssignals zumindest teilweise in dem zweiten Hörhilfegerät.In a conceivable embodiment of the method according to the invention, the evaluation of the detected acoustic input signal takes place at least partially in the second hearing aid device.

Das zumindest teilweise Auswerten des erfassten akustischen Eingangssignals in dem zweiten Hörhilfegerät nutzt auf vorteilhafte Weise die in dem Hörhilfegerät vorhandenen Signalverarbeitungsressourcen und reduziert den Aufwand in einer externen Analysevorrichtung. Es wäre sogar denkbar, dass der gesamte Analysevorgang durch das Hörhilfegerät ausgeführt wird.The at least partial evaluation of the detected acoustic input signal in the second hearing aid device advantageously utilizes the signal processing resources present in the hearing aid device and reduces the effort in an external analysis device. It would even be conceivable that the entire analysis process is performed by the hearing aid.

Gemäß Anspruch 1 ist das Verfahren zur Analyse Teil eines Verfahrens zum Übernehmen einer Hörhilfegeräteeinstellung von einem ersten Hörhilfegerät auf ein zweites Hörhilfegerät. Das Verfahren zum Übernehmen weist zusätzlich den Schritt auf, einen Einstellparameter für das zweite Hörhilfegerät auf der Grundlage der Auswertung des erfassten akustischen Ausgangssignals zu ermitteln. Es ist dabei ebenso möglich, dass mehrere oder alle Einstellparameter des zweiten Hörhilfegerätes ermittelt werden. Schließlich wird bzw. werden der bzw. die Einstellparameter des zweiten Hörhilfegerätes auf der Grundlage des ermittelten Einstellparameters eingestellt.According to claim 1, the method of analysis is part of a method for adopting a hearing aid setting from a first hearing aid to a second hearing aid. The method for adopting additionally comprises the step of setting a parameter for the second hearing aid based on the evaluation of the detected acoustic output to investigate. It is also possible that several or all setting parameters of the second hearing aid are determined. Finally, the parameter (s) of the second hearing aid will be adjusted based on the determined adjustment parameter.

Das erfindungsgemäße Verfahren zum Übernehmen einer Hörhilfegeräteeinstellung ermöglicht es auf vorteilhafte Weise bei der Bestimmung der Einstellparameter durch die Analyse von Signalen des Mikrofons des Hörhilfegerätes auch Abweichungen des Mikrofons des zweiten Hörhilfegerätes von den idealen Kennwerten zu berücksichtigen und so die Einstellung mit höherer Genauigkeit vorzunehmen.The method according to the invention for adopting a hearing aid setting advantageously makes it possible to take into account deviations of the microphone of the second hearing aid from the ideal characteristic values in the determination of the setting parameters by analyzing signals from the microphone of the hearing aid and thus to carry out the setting with higher accuracy.

In einer denkbaren Ausführungsform des erfindungsgemäßen Verfahrens erfolgt das Einstellen des zweiten Hörhilfegerätes durch eine Bedienperson.In one conceivable embodiment of the method according to the invention, the adjustment of the second hearing aid by an operator.

Dies ermöglicht auf vorteilhafte Weise, auch bei einem zweiten Hörhilfegerät, für das z.B. keine geeignete Schnittstelle für die Programmierung in der erfindungsgemäßen Vorrichtung vorhanden ist, eine erfindungsgemäße Einstellung der Einstellparameter vorzunehmen.This advantageously makes it possible, even in a second hearing aid device, for e.g. there is no suitable programming interface in the device according to the invention for carrying out an adjustment of the adjustment parameters according to the invention.

In einer anderen Ausführungsform des erfindungsgemäßen Verfahrens erfolgt das Einstellen des zweiten Hörhilfegerätes über eine Signalverbindung zu dem zweiten Hörhilfegerät.In another embodiment of the method according to the invention, the setting of the second hearing aid device takes place via a signal connection to the second hearing aid device.

So können Fehler bei der Übertragung der Einstellparameter durch eine Bedienperson vermieden und der Einstellvorgang beschleunigt werden.Thus, errors in the transmission of the setting parameters can be avoided by an operator and the setting process can be accelerated.

In einer denkbaren Ausführungsform der erfindungsgemäßen Vorrichtung weist diese eine Signalquelle zur Erzeugung eines akustischen Prüfsignals auf.In a conceivable embodiment of the device according to the invention, this has a signal source for generating an acoustic test signal.

Die Signalquelle ermöglicht es auf vorteilhafte Weise, reproduzierbare und vorbestimmte akustische Signale für eine Analyse der Einstellung des ersten Hörhilfegerätes bereitzustellen.The signal source advantageously enables reproducible and predetermined acoustic signals for analysis to provide the setting of the first hearing aid.

In einer möglichen Ausführungsform der erfindungsgemäßen Vorrichtung weist diese einen akusto-elektrischen Referenzwandler zur Aufnahme des akustischen Prüfsignals auf.In one possible embodiment of the device according to the invention, this has an acousto-electrical reference transducer for receiving the acoustic test signal.

Mittels des akusto-elektrischen Referenzwandlers, beispielsweise einem Messmikrofon, kann die Vorrichtung das Prüfsignal auf vorbestimmte und reproduzierbare Weise aufnehmen und für einen Vergleich mit dem Signal des zweiten Hörhilfegerätes bzw. zu einer gemeinsamen Verarbeitung bereitstellen. Auf vorteilhafte Weise ist die erfindungsgemäße Vorrichtung daher nicht darauf angewiesen, einige wenige vorbestimmte Prüfsignale zu nutzen, sondern es kann beispielsweise auch eine gewohnte Hörumgebung eines Hörgeräteträgers zur Analyse genutzt werden.By means of the acousto-electrical reference transducer, for example a measuring microphone, the device can record the test signal in a predetermined and reproducible manner and provide it for comparison with the signal of the second hearing aid or for joint processing. Advantageously, the device according to the invention is therefore not dependent on using a few predetermined test signals, but it can also be used, for example, a familiar hearing environment of a hearing aid wearer for analysis.

Gemäß unabhängigem Anspruch 7 weist die Vorrichtung weiterhin eine Ermittlungseinrichtung auf, die dazu ausgelegt ist, aus einem Ergebnis der Analyseeinrichtung einen Einstellparameter für das zweite Hörhilfegerät derart zu ermitteln, dass eine Transferfunktion des zweiten Hörhilfegerätes unter Anwendung des Einstellparameters einer Transferfunktion des ersten Hörhilfegerätes angenähert ist. Mit anderen Worten, es wird das akustische Verhalten der zweiten Hörvorrichtung so verändert, dass die messbaren und/oder von einem Träger wahrnehmbaren akustischen Eigenschaften sich weniger von den gemessenen bzw. wahrgenommenen akustischen Eigenschaften des ersten Hörhilfegerätes unterscheiden. Idealerweise kann sogar ein gleiches oder für den Träger nicht mehr unterscheidbares Verhalten erzielt werden.According to independent claim 7, the device further comprises a determination device which is designed to determine a setting parameter for the second hearing aid device from a result of the analysis device in such a way that a transfer function of the second hearing aid device is approximated using the adjustment parameter of a transfer function of the first hearing aid device. In other words, the acoustic behavior of the second hearing device is changed so that the measurable and / or perceptible by a carrier acoustic properties are less different from the measured or perceived acoustic properties of the first hearing aid. Ideally, even an equal or indistinguishable behavior for the wearer can be achieved.

Auf vorteilhafte Weise kann es so erreicht werden, dass der Träger bei einem Wechsel von dem ersten Hörhilfegerät zu dem zweiten Hörhilfegerät das gleiche Hörempfinden hat und das neue Gerät akzeptiert.In an advantageous manner, it can be achieved that the wearer has the same hearing when switching from the first hearing aid to the second hearing aid and accepts the new device.

In einer denkbaren Ausführungsform der Vorrichtung weist dies weiterhin eine Einstelleinrichtung auf, die dazu ausgelegt ist, den Einstellparameter in dem zweiten Hörhilfegerät einzustellen. Es ist aber auch möglich, dass die Einstellvorrichtung dazu ausgelegt ist, mehrere oder alle Einstellparameter des zweiten Hörhilfegerätes durch die Einstellvorrichtung zu ändern.In a conceivable embodiment of the device, this further comprises an adjustment device which is designed to set the adjustment parameter in the second hearing aid device. However, it is also possible for the setting device to be designed to change several or all setting parameters of the second hearing aid by the setting device.

Die erfindungsgemäße Vorrichtung kann so schnell und ohne Übertragungsfehler eine Einstellung des zweiten Hörhilfegerätes vornehmen.The device according to the invention can make an adjustment of the second hearing aid device as quickly and without transmission error.

In einer möglichen Ausführungsform der erfindungsgemäßen Vorrichtung ist das Koppelmittel ein passiver mechanischer Adapter, welcher das erste Hörhilfegerät mit dem zweiten Hörhilfegerät auf akustisch definierte Weise verbindet. Das Koppelmittel kann beispielsweise in Form eines Hohlkörpers ausgebildet sein, der einen Innenraum aufweist, in dem sich sowohl der elektro-akustische Wandler des ersten Hörhilfegerätes und der akusto-elektrische Wandler des zweiten Hörhilfegerätes befinden oder mit diesem in Fluidaustausch stehen. Bevorzugter Weise ist dabei der Innenraum des Kopplers durch Wände des Kopplers und die Gehäuse der Hörhilfegeräte von der Umgebung im Wesentlichen fluiddicht abgeschlossen, sodass Umgebungsgeräusche nur mit hoher Dämpfung von beispielsweise 40, 60, 80 oder mehr Dezibel in den Innenraum des Kopplers dringen können.In one possible embodiment of the device according to the invention, the coupling means is a passive mechanical adapter which connects the first hearing aid device to the second hearing aid device in an acoustically defined manner. The coupling means may be formed for example in the form of a hollow body having an interior, in which both the electro-acoustic transducer of the first hearing aid and the acousto-electrical converter of the second hearing aid are or are in fluid exchange with this. Preferably, the interior of the coupler is closed by walls of the coupler and the housing of the hearing aid from the environment substantially fluid-tight, so that ambient noise can penetrate only with high attenuation of, for example, 40, 60, 80 or more decibels in the interior of the coupler.

Das Koppelmittel erlaubt es auf einfache Weise die Ausgangssignale des ersten Hörhilfegerätes zu dem Mikrofon bzw. den Mikrofonen des zweiten Hörhilfegerätes zu leiten, um dessen Eigenschaften nachvollziehbar und ungestört zu analysieren.The coupling means makes it possible to easily direct the output signals of the first hearing aid to the microphone or the microphones of the second hearing aid to analyze its characteristics traceable and undisturbed.

Die oben beschriebenen Eigenschaften, Merkmale und Vorteile dieser Erfindung sowie die Art und Weise, wie diese erreicht werden, werden klarer und deutlicher verständlich im Zusammenhang mit der folgenden Beschreibung der Ausführungsbeispiele, die im Zusammenhang mit den Zeichnungen näher erläutert werden.The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following description of the embodiments, which are explained in more detail in connection with the drawings.

Die Fig. 1 zeigt schematisch ein Hörhilfegerät 1, wie es sowohl als erstes Hörhilfegerät 31, dessen Einstellungen mittels des erfindungsgemäßen Verfahrens auf ein unterschiedliches zweites Hörhilfegerät 32 übernommen werden soll, oder als zweites Hörhilfegerät 32, das eingestellt werden soll, Verwendung finden kann.The Fig. 1 schematically shows a hearing aid 1, as it can be used both as the first hearing aid 31, the settings of which should be adopted by the method according to the invention to a different second hearing aid 32, or as a second hearing aid 32 to be adjusted.

Das Hörhilfegerät 1 weist ein Gehäuse 10 auf, in dem ein oder mehrere Mikrofone 11 angeordnet sind, sodass sie Schallwellen aus einer Umgebung des Hörhilfegerätes 1 aufnehmen können. Weiterhin befindet sich in dem Gehäuse 10 eine Signalverarbeitungseinrichtung 12, die die von den Mikrofonen 11 in elektrische Signale umgewandelten Schallwellen zur weiteren Verarbeitung entgegen nimmt. Bei der Verarbeitung durch die Signalverarbeitungseinrichtung 12 handelt es sich beispielsweise um die in Hörhilfegeräten übliche Funktion wie frequenzabhängige Verstärkung. Denkbar sind aber auch komplexere Signalverarbeitungsfunktionen wie Ausbildung von Richtwirkungen mit Signalen mehrere Mikrofone oder Filterung von Störgeräuschen. Bei einem binauralen Hörhilfesystem ist ebenfalls eine binaurale Signalverarbeitung denkbar.The hearing aid device 1 has a housing 10, in which one or more microphones 11 are arranged, so that they can absorb sound waves from an environment of the hearing aid device 1. Furthermore, in the housing 10 there is a signal processing device 12, which receives the sound waves converted by the microphones 11 into electrical signals for further processing. The processing by the signal processing device 12 is, for example around the usual in Hearing Aids function such as frequency-dependent amplification. However, more complex signal processing functions are also conceivable, such as the formation of directional effects with signals of several microphones or filtering of interfering noises. In a binaural hearing aid system, a binaural signal processing is also conceivable.

Weiterhin befindet sich in dem Gehäuse 10 ein Hörer 13, der das von der Signalverarbeitungseinrichtung 12 verarbeitete elektrische Signal empfängt und es in akustische Schallwellen umwandelt, die in die Umgebung außerhalb des Gehäuses 10 ausgegeben werden. Die Energieversorgung erfolgt durch eine Batterie oder einen Akkumulator 14, der ebenfalls in dem Gehäuse 10 angeordnet ist.Furthermore, in the housing 10 there is a receiver 13, which receives the electrical signal processed by the signal processing device 12 and converts it into acoustic sound waves, which are emitted into the environment outside the housing 10. The power supply is effected by a battery or an accumulator 14, which is likewise arranged in the housing 10.

Zumindest das zweite Hörhilfegerät 32 weist darüber hinaus eine Schnittstelle 15 auf, über die es in Signalverbindung 38 mit einer Steuerung 36, siehe Fig. 3 und 4 treten kann. Mittels der Schnittstelle 15 ist das Hörhilfegerät 31,32 dazu ausgelegt, über das Mikrofon 11 empfangene Schallwellen als analoge oder digitale akustische Signale bzw. als daraus abgeleitete Signale an die Steuerung 36 zu senden.At least the second hearing aid device 32 also has an interface 15, via which it is in signal connection 38 with a controller 36, see Fig. 3 and 4 can occur. By means of the interface 15, the hearing aid device 31, 32 is designed to transmit sound waves received via the microphone 11 to the control 36 as analogue or digital acoustic signals or as signals derived therefrom.

In der Fig. 1 und den Fig. 2 bis 4 ist als Hörhilfegerät 1, 31, 32 jeweils ein Hinter-dem-Ohr-Hörhilfegerät dargestellt. Das erfindungsgemäße Verfahren ist aber mit einem geeigneten Koppelmittel 20 auch für In-dem-Ohr-, In-dem-Kanal-, Hörer - in-dem-Kanal- oder anderweitigen Hörhilfegerät anwendbar. Dabei ist es auch denkbar, dass das Verfahren zur Übertragung von Einstellungen von einem Hinter-dem-Ohr-Hörhilfegerät auf ein In-dem-Ohr-Hörhilfegerät genutzt wird. Zwingend erforderlich ist lediglich, dass das erste Hörhilfegerät 31 einen Hörer 13 und das zweite Hörhilfegerät 32 ein Mikrofon 11 aufweist. Beispielsweise könnte das akustische Signal auch über eine Induktionsspule 16 von der Steuerung 36 in das erste Hörhilfegerät 31 gelangen.In the Fig. 1 and the Fig. 2 to 4 is shown as a hearing aid 1, 31, 32 each have a behind-the-ear hearing aid. However, the method according to the invention can also be used with a suitable coupling means 20 for in-the-ear, in-the-canal, earpiece-in-the-canal or other hearing aid devices. It is also conceivable that the method for transmitting settings from a behind-the-ear hearing aid to an in-the-ear hearing aid is used. All that is necessary is that the first hearing aid device 31 has a handset 13 and the second hearing aid device 32 has a microphone 11. For example, the acoustic signal could also pass via an induction coil 16 from the controller 36 into the first hearing aid device 31.

Fig. 2 zeigt schematisch eine erfindungsgemäße akustische Kopplung eines ersten Hörhilfegerätes 31 und eines zweiten Hörhilfegerätes 32 zur Durchführung des erfindungsgemäßen Verfahrens. Die Darstellung ist nicht maßstabsgerecht. Fig. 2 schematically shows an inventive acoustic coupling of a first hearing aid device 31 and a second hearing aid device 32 for carrying out the method according to the invention. The representation is not to scale.

In einer Ausführungsform ist das Koppelmittel 20 als Schuh oder Schlauch ausgebildet, der das erste Hörhilfegerät 31 und das zweite Hörhilfegerät 32 zumindest teilweise aufnimmt. Bei einer erfindungsgemäßen Anordnung des ersten Hörhilfegerätes 31 und des zweiten Hörhilfegerätes 32 befindet sich zumindest die Öffnung, über die das erste Hörhilfegerät 31 den von dem Hörer 13 erzeugten Schall an die Umgebung abgibt, in einem Innenraum 25 des Koppelmittels 20. Dagegen befindet sich das oder die Mikrofone 11 bzw. eine Öffnung in dem Gehäuse 10, über die Schallwellen aus der Umgebung an das Mikrofon 11 des ersten Hörhilfegerätes 31 gelangen können, außerhalb des Koppelmittels 20.In one embodiment, the coupling means 20 is designed as a shoe or hose, which at least partially accommodates the first hearing aid device 31 and the second hearing aid device 32. In an inventive arrangement of the first hearing aid device 31 and the second hearing aid device 32 is at least the opening through which the first hearing aid 31 emits the sound generated by the listener 13 to the environment, in an interior 25 of the coupling means 20. In contrast, there is or the microphones 11 or an opening in the housing 10, via which sound waves from the environment can reach the microphone 11 of the first hearing aid device 31, outside of the coupling means 20.

Genau umgekehrt ist es bei dem zweiten Hörhilfegerät 32, dessen Mikrofon bzw. Mikrofone 11 in Fluidverbindung mit dem Innenraum 25 stehen und Schallwellen aus dem Innenraum 25 empfangen können. Der Hörer 11 des zweiten Hörhilfegerätes steht hingegen nicht in Fluidverbindung mit dem Innenraum 25, sodass das bzw. die Mikrofone 11 des zweiten Hörhilfegerätes 32 von dessen Hörer 13 im Wesentlichen akustisch isoliert sind, bis auf mögliche Schallleitung durch das Hörhilfegerät selbst.The situation is exactly the opposite with the second hearing aid device 32, whose microphone or microphones 11 are in fluid communication with the interior 25 and can receive sound waves from the interior 25. The handset 11 of the second hearing aid device, however, is not in fluid communication with the interior 25, so that the or the microphones 11 of the second hearing aid 32 are substantially acoustically isolated from the listener 13, except for possible sound conduction through the hearing aid itself.

Es ist auch denkbar, dass der Hörer 13 des zweiten Hörhilfegerätes 32 akustisch von dem bzw. den Mikrofonen 11 des ersten Hörhilfegerätes 31 isoliert ist. Denkbar wäre es, dass an dem Koppelmittel 20 zu diesem Zweck eine abgeschlossene Kammer oder einen Abschluss für das Gehäuse 21 ausgebildet ist, der für die akustische Entkopplung sorgt.It is also conceivable that the handset 13 of the second hearing aid device 32 is acoustically isolated from the microphone or microphones 11 of the first hearing aid device 31. It would be conceivable that on the coupling means 20 for this purpose, a closed chamber or a conclusion for the housing 21 is formed, which ensures the acoustic decoupling.

Zwischen dem Koppelmittel 20 und den Gehäusen 10 des ersten Hörhilfegerätes 31 und des zweiten Hörhilfegerätes 32 ist an der gemeinsamen Grenze zur Umgebung ein Dichtmittel 22 angeordnet, dass dafür sorgt, dass der Innenraum 25 des Koppelmittels 20 durch dessen Außenwand, den Dichtmitteln 22 und den Gehäusen 10 fluiddicht bzw. akustisch von der Umgebung getrennt ist. Ist das Koppelmittel 20 selbst aus einem elastischen Material gefertigt, kann das Dichtmittel 22 aber auch entfallen.Between the coupling means 20 and the housings 10 of the first hearing aid device 31 and the second hearing aid device 32, a sealing means 22 is disposed at the common boundary to the environment, that ensures that the interior 25 of the coupling means 20 by its outer wall, the sealing means 22 and the housings 10 is fluid-tight or acoustically separated from the environment. If the coupling means 20 itself is made of an elastic material, the sealing means 22 can also be dispensed with.

Das Koppelmittel 20 kann beispielsweise aus zwei Halbschalen 21 gefertigt sein, die sich zum Einlegen der Hörhilfegeräte 31, 32 trennen lassen. An der Trennlinie zwischen den Halbschalen 21 kann wieder ein Dichtmittel vorgesehen sein. Die Halbschalen 21 können separat ausgebildet sein und durch ein Haltemittel, z.B. einen Clip-Verschluss, einen äußeren Rahmen, einen elastischen Bügel oder einfach nur ein Gummiband zusammengehalten werden. Es ist aber auch denkbar, dass die beiden Halbschalen durch ein Gelenk oder Scharnier verbunden sind. In ihrem Inneren weisen die Halbschalen 21 vorzugsweise Strukturen 23 auf, die geeignet sind, das erste und/oder zweite Hörhilfegerät 31, 32 in ihrer Lage relativ zu dem Koppelmittel 20 fixiert werden.The coupling means 20 may for example be made of two half-shells 21, which can be separated for insertion of the hearing aid devices 31, 32. At the dividing line between the half-shells 21, a sealing means may again be provided. The half shells 21 may be formed separately and held by a retaining means, e.g. a clip closure, an outer frame, an elastic strap or just a rubber band are held together. But it is also conceivable that the two half-shells are connected by a hinge or hinge. In their interior, the half shells 21 preferably have structures 23 which are suitable for fixing the first and / or second hearing aid device 31, 32 in their position relative to the coupling means 20.

Das Koppelmittel 20 kann aber auch aus einem elastischen Material als Schlauch oder Hülse gefertigt sein, sodass das erste Hörhilfegerät 31 von einem Ende eingeführt wird und das zweite Hörhilfegerät von dem gegenüberliegenden Ende. Vorzugsweise ist das Dichtmittel 22 dabei den äußeren Konturen der Hörhilfegeräte nachgeformt, sodass nach dem Einführen die relative Lage der Hörhilfegeräte zueinander in einer vorbestimmten Anordnung sind und die Dichtwirkung zwischen Innenraum 25 und Umgebung erzielt wird.But the coupling means 20 may also be made of an elastic material as a tube or sleeve, so that the first hearing aid 31 is inserted from one end and the second hearing aid from the opposite end. Preferably, the sealing means 22 is thereby reshaped to the outer contours of the hearing aid devices, so that after insertion, the relative position of the hearing aid devices to each other in a predetermined arrangement and the sealing effect between the interior 25 and the environment is achieved.

Vorzugsweise weist der Innenraum 25 dämpfende Eigenschaften auf, sodass die akustische Kopplung zwischen erstem Hörhilfegerät 31 und zweitem Hörhilfegerät 32 möglichst wenige oder gar keine Resonanzen aufweist und eine Übertragungsfunktion annähernd linear ist. Dämpfende Eigenschaften können in einer Ausführungsform durch ein weiches und möglicherweise auf der dem Innenraum zugewandten Seite poröses Material erzielt werden. Denkbar sind auch Grate oder andere Oberflächenstrukturen, die diffus reflektieren und die Ausbildung einer Resonanz verhindern.Preferably, the interior space 25 has damping properties, so that the acoustic coupling between the first hearing aid device 31 and the second hearing aid device 32 has as few or no resonances as possible and a transfer function is approximately linear. Damping properties can be achieved in one embodiment by a soft and possibly on the interior facing side porous material. Also conceivable are burrs or other surface structures which diffusely reflect and prevent the formation of a resonance.

In einer denkbaren Ausführungsform ist dabei ein Volumen des Innenraums 25 vergleichbar einem Volumen zwischen Hörer 13 des ersten Hörhilfegerätes 32 und einem Trommelfell in einem Gehörgang eines Trägers, sodass die akustischen Eigenschaften des Hörers in dem Gehörgang nachgebildet werden. Das Volumen des Innenraums kann beispielsweise 1 cm3, 0,5 cm3 oder 0,25 cm3 betragen. Der Abstand zwischen dem ersten Hörhilfegerät 31 und dem zweiten Hörhilfegerät kann beispielsweise 10 mm, 5 mm oder 3 mm betragen.In one conceivable embodiment, a volume of the inner space 25 is comparable to a volume between the handset 13 of the first hearing aid 32 and a tympanic membrane in an auditory canal of a wearer, so that the acoustic properties of the handset are reproduced in the auditory canal. The volume of the interior may be, for example, 1 cm 3 , 0.5 cm 3 or 0.25 cm 3 . The distance between the first hearing aid device 31 and the second hearing aid device may be, for example, 10 mm, 5 mm or 3 mm.

Fig. 3 zeigt eine denkbare Vorrichtung 30 zur Ausführung des erfindungsgemäßen Verfahrens. Die Vorrichtung 30 weist eine Steuerung 36 auf, die dazu ausgelegt ist, ein Prüfsignal über eine erste Signalverbindung 37 auszugeben und über eine zweite Signalverbindung 38 mit dem zweiten Hörhilfegerät 32 Ergebnisse zu empfangen und auch Einstellungen an dem zweiten Hörhilfegerät vorzunehmen. Fig. 3 shows a conceivable device 30 for carrying out the method according to the invention. The device 30 has a controller 36 which is designed to output a test signal via a first signal connection 37 and to receive results via a second signal connection 38 with the second hearing aid device 32 and also to make adjustments to the second hearing aid device.

In einer denkbaren Ausführungsform sind das erste Hörhilfegerät 31 und das zweite Hörhilfegerät 32, die wie zu Fig. 2 erläutert über ein Koppelmittel 20 akustisch miteinander gekoppelt sind, in einem Prüfraum 35 angeordnet. Weiterhin befindet sich in dem Prüfraum 35 eine Schallquelle 33, die von der Steuerung 36 gesteuert über die Signalverbindung 37 ein Prüfsignal akustisch ausgibt. Die Signalverbindung 37 kann eine analoge elektrische Leitung sein, die mit einem DA-Wandler des Steuergerätes verbunden ist. Denkbar sind aber auch digitale Verbindungen zur Audiosignalübertragung wie TOS-LINK, HDMI, USB oder auch drahtlos wie Bluetooth. Im Bereich der Audiologie findet auch HI-PRO als Programmierschnittstelle Verwendung.In a conceivable embodiment, the first hearing aid device 31 and the second hearing aid device 32, the like Fig. 2 explained via a coupling means 20 are acoustically coupled to each other, arranged in a test room 35. Furthermore, located in the test room 35 is a sound source 33, which is controlled by the controller 36 via the signal connection 37 outputs a test signal acoustically. The signal connection 37 may be an analog electrical line which is connected to a DA converter of the control unit. Also conceivable are digital connections for audio signal transmission such as TOS-LINK, HDMI, USB or wireless as Bluetooth. In the field of audiology, HI-PRO is also used as a programming interface.

Der Prüfraum 35 ist dazu ausgelegt, externe Störgeräusche zu reduzieren und eine möglichst frequenzneutrale Ausbreitung des Prüfsignals in seinem Inneren zu ermöglichen. Ein derartiger Prüfraum kann ein schalltoter Raum sein, aber auch eine kleine Messbox, die im Wesentlichen nur Platz für die Hörhilfegeräte 31,32, das Koppelmittel 20 und die Schallquelle 33 bietet. In geeigneter Umgebung ohne Störgeräusche kann der Prüfraum 35 aber auch entfallen.The test chamber 35 is designed to reduce external noise and a possible frequency-neutral propagation allow the test signal in its interior. Such a test room can be a sound-deadening room, but also a small measuring box, which essentially only provides space for the hearing aids 31, 32, the coupling means 20 and the sound source 33. In a suitable environment without noise, the test room 35 but also omitted.

Fig. 4 zeigt eine andere mögliche Vorrichtung (30) zur Ausführung des erfindungsgemäßen Verfahrens. Der wesentliche Unterschied zu Fig. 3 ist es, dass anstelle der von der Steuerung 36 gesteuerten Schallquelle 33 eine andere möglicherweise natürliche Schallquelle tritt. Symbolisch ist hier ein Sprecher dargestellt, der stellvertretend für natürliche Geräusche aus der Umgebung eines Hörhilfegeräteträgers steht. Fig. 4 shows another possible device (30) for carrying out the method according to the invention. The main difference too Fig. 3 it is that instead of the controlled by the controller 36 sound source 33 another possibly natural sound source occurs. Symbolically, a speaker is shown here, who is representative of natural sounds from the environment of a hearing aid wearer.

Da der Steuerung das Signal der Schallquelle unbekannt ist, ist es zur Analyse des von dem zweiten Hörhilfegerät 32 aufgenommenen Signals erforderlich, die Schallquelle genau zu erfassen. Dafür ist in dieser Ausführungsform ein Mikrofon 34 mit vorbestimmten bekannten Eigenschaften vorgesehen, das parallel zu dem ersten Hörhilfegerät 31 das Signal der Schallquelle aufnimmt.Since the control of the signal of the sound source is unknown, it is necessary for the analysis of the recorded signal from the second hearing aid 32, to accurately detect the sound source. For this purpose, a microphone 34 is provided with predetermined known properties in this embodiment, which receives the signal of the sound source parallel to the first hearing aid 31.

Wie zu Fig. 3 erläutert, ist es auch möglich, dass die Vorrichtung aus Fig. 4 sich in einem Prüfraum 35 befindet. Es ist aber auch denkbar, insbesondere wenn die Steuerung 36 ein tragbares Gerät wie ein tragbarer Computer ist, das erfindungsgemäße Verfahren in der gewohnten Hörumgebung des Hörhilfegeräteträgers auszuführen.How to Fig. 3 explained, it is also possible that the device off Fig. 4 is located in a test room 35. However, it is also conceivable, in particular if the controller 36 is a portable device such as a portable computer, to carry out the method according to the invention in the familiar hearing environment of the hearing aid wearer.

Fig. 5 zeigt einen schematischen Ablaufplan einer möglichen Ausführungsform des erfindungsgemäßen Verfahrens. Fig. 5 shows a schematic flowchart of a possible embodiment of the method according to the invention.

In einem Schritt S10 wird der elektro-akustische Wandler des ersten Hörhilfegerätes 31 mit dem akusto-elektrischen Wandler 32 des zweiten Hörhilfegerätes mittels des Koppelmittels 20 akustisch gekoppelt, wie es zu Fig. 2 beschrieben ist. Dabei sind die Mikrofone 11 die akusto-elektrischen Wandler und die Hörer 13 die elektrisch-akustischen Wandler.In a step S10, the electro-acoustic transducer of the first hearing aid device 31 is acoustically coupled to the acousto-electrical transducer 32 of the second hearing aid device by means of the coupling means 20, as is the case Fig. 2 is described. there For example, the microphones 11 are the acousto-electrical converters and the listeners 13 are the electrical-acoustic transducers.

In einem Schritt S20 wird der akusto-elektrischen Wandler des ersten Hörhilfegerätes 13 mit einem akustischen Prüfsignal beschallt. Das Mikrofon 11 des ersten Hörhilfegerätes 31 wandelt die Schallwellen in ein elektrisches Signal um, das von der Signalverarbeitungseinrichtung 12 gemäß den Einstellungen des ersten Hörhilfegerätes 31 frequenzabhängig verstärkt und gefiltert wird. Das resultierende elektrische Signal wird von dem Hörer 13 in eine Schallwelle umgewandelt und in den Innenraum 25 des Koppelmittels 20 abgegeben.In a step S20, the acousto-electrical converter of the first hearing aid device 13 is sonicated with an acoustic test signal. The microphone 11 of the first hearing aid device 31 converts the sound waves into an electrical signal which is frequency-dependent amplified and filtered by the signal processing device 12 in accordance with the settings of the first hearing aid device 31. The resulting electrical signal is converted by the receiver 13 into a sound wave and emitted into the interior 25 of the coupling means 20.

In einem Schritt S30 wird das akustischen Ausgangssignals des elektro-akustischen Wandlers bzw. des Hörers 13 des ersten Hörhilfegerätes 31 mittels des akusto-elektrischen Wandlers bzw. des Mikrofons 11 des zweiten Hörhilfegerätes 32 erfasstIn a step S30, the acoustic output signal of the electro-acoustic transducer or the handset 13 of the first hearing aid device 31 is detected by means of the acousto-electrical transducer or the microphone 11 of the second hearing aid device 32

In einem Schritt S40 wird das erfasste akustische Ausgangssignal ausgewertet.In a step S40, the detected acoustic output signal is evaluated.

Die Auswertung kann in einer Ausführungsform in der Steuerung 36 erfolgen, die die Analyseeinrichtung als Untereinheit aufweist oder die Funktionalität der Analyseeinrichtung bereitstellt. Dazu wird das erfasste Ausgangssignal analog oder nach einer A/D-Wandlung digital über die Signalverbindung 38 übertragen. Wie bereits zu Signalverbindung 37 erläutert, kann dabei eine Vielzahl von Signalverbindungsarten Verwendung finden. Die Auswertung erfolgt in der Steuerung 36, indem das Prüfsignal mit dem erfassten Ausgangssignal verglichen wird. Dies kann beispielsweise ein Vergleich der Pegel in verschiedenen Frequenzbändern nach einer Fourier-Transformation sein, um die frequenzabhängige Verstärkung zu bestimmen. Denkbar ist auch das Erfassen von zeitabhängigen Regelkonstanten, die durch sich schnell ändernde Prüfsignale bestimmt werden können.In one embodiment, the evaluation can take place in the controller 36, which has the analysis device as a subunit or provides the functionality of the analysis device. For this purpose, the detected output signal is transmitted digitally via the signal connection 38 analogously or after an A / D conversion. As already explained for signal connection 37, a multiplicity of signal connection types can be used in this case. The evaluation takes place in the controller 36 by comparing the test signal with the detected output signal. This may be, for example, a comparison of the levels in different frequency bands after a Fourier transform to determine the frequency-dependent gain. Also conceivable is the acquisition of time-dependent control constants, which can be determined by rapidly changing test signals.

Dabei kann das Prüfsignal entweder wie in Fig. 3 von der Steuerung 36 erzeugt und daher bekannt sein, oder wie in Fig. 4 parallel zu dem Ausgangssignal erfasst werden.The test signal can either be as in Fig. 3 generated by the controller 36 and therefore be known, or as in Fig. 4 be detected in parallel with the output signal.

Denkbar ist es auch, dass die Signalverarbeitungseinrichtung 12 des zweiten Hörhilfegerätes 32 dazu ausgelegt ist, die Analyse selbst oder zumindest in Teilschritten auszuführen. So ist es beispielsweise denkbar, dass die Signalverarbeitungseinrichtung 12 bereits eine Fourier-Transformation ausführt und der Steuerung 36 die Amplituden in den einzelnen Frequenzbändern mitteilt. Dazu weist die Signalverarbeitungseinrichtung 12 die Analyseeinrichtung als Untereinheit auf oder stellt die Funktionalität der Analyseeinrichtung bereit.It is also conceivable that the signal processing device 12 of the second hearing aid device 32 is designed to perform the analysis itself or at least in sub-steps. Thus, it is conceivable, for example, that the signal processing device 12 already carries out a Fourier transformation and notifies the controller 36 of the amplitudes in the individual frequency bands. For this purpose, the signal processing device 12 has the analysis device as a subunit or provides the functionality of the analysis device.

In einer möglichen Ausführungsform des erfindungsgemäßen Verfahrens weist diese weiterhin den Schritt S50 auf, einen Einstellparameter für das zweite Hörhilfegerät auf der Grundlage der Auswertung des erfassten akustischen Ausgangssignals zu ermitteln. Beispielsweise kann aus der ermittelten frequenzabhängigen Amplituden die Steuerung 36 einen Parametersatz für eine frequenzabhängige Verstärkung für das zweite Hörhilfegerät 32 ermitteln, mit dem dieses bei konstanter Eingangsamplitude die gewünschte Ausgangskennlinie erzeugt, beispielsweise durch normieren der frequenzabhängigen Amplituden des erfassten Ausgangssignals mit frequenzabhängigen Amplituden des Eingangssignals.In a possible embodiment of the method according to the invention, the latter furthermore has the step S50 of determining a setting parameter for the second hearing aid device on the basis of the evaluation of the detected acoustic output signal. For example, from the determined frequency-dependent amplitudes, the controller 36 can determine a parameter set for a frequency-dependent gain for the second hearing aid 32 with which this generates the desired output characteristic at constant input amplitude, for example by normalizing the frequency-dependent amplitudes of the detected output signal with frequency-dependent amplitudes of the input signal.

In einer denkbaren Ausführungsform des erfindungsgemäßen Verfahrens ist auch ein Schritt S60 des Einstellens des zweiten Hörhilfegerätes auf der Grundlage des ermittelten Einstellparameters vorgesehen. Dabei ist es denkbar, dass die Steuerung 36 über die Signalleitung 38 eine Einstellung des Hörhilfegerätes vornimmt. Dies ist besonders einfach, wenn die Steuerung 36 ein Gerät zum Fitting ist, das auch sonst zum Einstellen von Hörhilfegeräten vorgesehen ist. Dieses kann zum Beispiel mit einer HI-PRO Schnittstelle versehen sein.In a conceivable embodiment of the method according to the invention, a step S60 of setting the second hearing aid device is also provided on the basis of the determined setting parameter. It is conceivable that the controller 36 makes an adjustment of the hearing aid via the signal line 38. This is particularly simple if the controller 36 is a fitting device that is otherwise provided for adjusting hearing aids. This can for example be provided with a HI-PRO interface.

Es ist aber auch denkbar, dass die Einstellung der Parameter an dem zweiten Hörhilfegerät manuell durch eine Bedienperson erfolgt, wenn beispielsweise das zweite Hörhilfegerät über keine oder keine kompatible Programmierschnittstelle verfügt.However, it is also conceivable that the adjustment of the parameters on the second hearing aid device takes place manually by an operator, for example if the second hearing aid device has no or no compatible programming interface.

Obwohl die Erfindung im Detail durch das bevorzugte Ausführungsbeispiel näher illustriert und beschrieben wurde, so ist die Erfindung nicht durch die offenbarten Beispiele eingeschränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen.Although the invention has been further illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
