Aus der EP 1 420 611 A1 ist bekannt, die Reihenfolge der Hörprogramme in Abhängigkeit der momentanen Hörumgebung umzuordnen.From the EP 1 420 611 A1 is a method and a hearing aid is known in which a program switching depending on the current listening environment in which the hearing aid is located takes place. Conventionally, in a hearing aid by operating a corresponding control element, eg a program selection button, from a hearing program with a specific program number (eg P2) to the hearing program with the next higher program number (eg P3) and from the hearing program with the highest program number (eg P5 ) to the hearing program with the lowest program number (eg P1). From the EP 1 420 611 A1 It is known to rearrange the order of the listening programs depending on the current listening environment.

Aus der EP 0 064 042 A1 ist ein Hörgerät mit einem Speicher bekannt, in dem mehrere Parametersätze (sog. "Hörprogramme") zur Anpassung der Signalverarbeitung im Hörgerät an unterschiedliche Hörsituationen gespeichert sind. Durch Betätigung einer Programmwahltaste oder durch Analyse eines akustischen Eingangssignals wird ein Parametersatz ausgewählt, der dann die Signalverarbeitung im Hörgerät bestimmt.From the EP 0 064 042 A1 a hearing device with a memory is known in which a plurality of parameter sets (so-called "hearing programs") are stored for adaptation of the signal processing in the hearing device to different listening situations. By pressing a program selection key or by analyzing an acoustic input signal, a parameter set is selected, which then determines the signal processing in the hearing aid.

Aus der EP 0 814 634 A1 ist ein programmierbares Hörgerätesystem zum Ermitteln optimaler Parametersätze bei einem Hörhilfegerät bekannt. Das bekannte Hörgerätesystem umfasst eine Anpasseinrichtung, welche einen Speicher für mehrere zur Auswahl stehende Parametersätze zur Anpassung der Signalverarbeitung an jeweils eine Hörsituation umfasst. Darüber hinaus zeichnet sich das bekannte Hörgerätesystem dadurch aus, dass mehrere Parametersätze für eine Hörsituation gespeichert sind. Es können somit für jede Hörsituation mehrere Parametersätze ausprobiert werden, bis schließlich für jede Hörsituation ein Parametersatz ausgewählt und im Hörgerät hinterlegt ist.From the EP 0 814 634 A1 is a programmable hearing aid system for determining optimal parameter sets in a hearing aid known. The known hearing aid system comprises an adaptation device which comprises a memory for a plurality of parameter sets available for the selection of the signal processing for each hearing situation.

Aus der EP 0 349 835 A1 ist ein Hörgerät mit einem Betätigungselement zur Veränderung der akustischen Verstärkungseinstellung sowie mit einem Betriebsartenschalter für zwei oder mehrere Betriebsarten bekannt. Dem Betätigungselement für die akustische Verstärkungseinstellung sind über den Betriebsartenschalter weitere Einstellfunktionen zuwählbar.From the EP 0 349 835 A1 is a hearing aid with an actuator for changing the acoustic gain setting and a mode switch for two or more modes known.

Aufgabe der vorliegenden Erfindung ist es, die Bedienung eines Hörhilfegerätes zu vereinfachen.The object of the present invention is to simplify the operation of a hearing aid.

Diese Aufgabe wird bei einem Hörhilfegerät oder Hörgerätesystem mit einem Eingangswandler zur Aufnahme eines Eingangssignals und Wandlung in ein elektrisches Signal, einer Signalverarbeitungseinheit zur Verarbeitung des elektrischen Signals, einem Ausgangswandler zur Abgabe eines Ausgangssignals, einer Bedieneinrichtung mit wenigstens einem betätigbaren Bedienelement zum Einstellen von Parametern, die die Signalverarbeitung in der Signalverarbeitungseinheit beeinflussen, und mit Analysemitteln zur Analyse des Eingangssignals dadurch gelöst, dass dem Bedienelement in Abhängigkeit des Ergebnisses der Signalanalyse unterschiedliche Einstellfunktionen zugeordnet sind.This object is achieved in a hearing aid or hearing aid system with an input transducer for receiving an input signal and conversion into an electrical signal, a signal processing unit for processing the electrical signal, an output transducer for outputting an output, an operating device having at least one actuatable operating element for setting parameters which influence the signal processing in the signal processing unit, and analysis means for analyzing the input signal in that the operating element is dependent on the result the signal analysis are assigned different setting functions.

Die Grundidee der Erfindung besteht darin, dem Benutzer eines Hörhilfegerätes eine Vielzahl manueller Einstellmöglichkeiten des Hörhilfegerätes zu bieten und trotzdem die Bedienung möglichst einfach zu gestalten. Hierzu werden den Bedienelementen in Abhängigkeit der akustischen Umgebung, in der sich das Hörgerät gerade befindet, automatisch unterschiedliche Einstellfunktionen zugeordnet. Ist das Hörhilfegerät beispielsweise mit einem Programmwahltaster ausgestattet, so kann zunächst eine automatische Programmeinstellung in Folge der Analyse des Eingangssignals erfolgen. Durch Betätigung des Programmwahltasters können dann weitere Hörprogramme manuell ausgewählt werden, wobei bei jeder Betätigung des Programmwahltasters nur zwischen solchen Hörprogrammen umgeschaltet wird, die für die erkannte Hörsituation geeignet sind. Dadurch können dem Hörgeräteträger mehr Programmalternativen angeboten werden als bei bekannten Hörgeräten, bei denen der Hörgeräteträger bei der Verwendung eines Programmwahltasters eine Vielzahl nicht für die aktuelle Hörsituation passender Hörprogramme durchlaufen müsste, um zu den passenden Einstellungen zu gelangen. Durch die Erfindung wird die Auswahl auf die für die Hörsituation geeigneten Hörprogramme beschränkt.The basic idea of the invention is to offer the user of a hearing aid device a multiplicity of manual adjustment possibilities of the hearing aid device and nevertheless to make the operation as simple as possible. For this purpose, the control elements are automatically assigned different setting functions as a function of the acoustic environment in which the hearing device is currently located. If the hearing aid device is equipped, for example, with a program selection button, an automatic program adjustment as a result of the analysis of the input signal can initially take place. By pressing the program selection button further hearing programs can then be selected manually, with each operation of the program selection button is switched only between those programs that are suitable for the detected hearing situation. As a result, the hearing aid wearer can be offered more program alternatives than in known hearing aids, in which the hearing aid wearer would have to go through a large number of hearing aids that are not suitable for the current hearing situation when using a program selection key in order to arrive at the appropriate settings. The invention restricts the selection to the hearing programs suitable for the hearing situation.

Die Erfindung ist bei der durch Betätigung eines Bedienelements ausführbaren Einstellfunktion nicht auf die Programmwahl beschränkt. Vielmehr erstreckt sie sich auf beliebige Bedienelemente und Einstellfunktionen. So kann beispielsweise ein normalerweise als Lautstärkesteller dienendes Bedienelement während der erkannten Hörsituation "Gespräch mit Störgeräusch" zur Anpassung der Kontrastverstärkung dienen.The invention is not limited to the program selection in executable by pressing a control adjustment function. Rather, it extends to any controls and adjustment functions. For example, a normally used as a volume control operating element During the recognized hearing situation "conversation with noise" serve to adjust the contrast enhancement.

Die Analyse der akustischen Umgebung, in der sich das Hörgerät gerade befindet, erfolgt in bekannter Weise durch die Ermittlung charakteristischer Kenngrößen, die beispielsweise den Signalpegel, die Modulationstiefe oder die spektrale Verteilung eines akustischen Eingangssignals betreffen. In Abhängigkeit der erkannten Hörumgebung wird dann gemäß der Erfindung wenigstens einem Bedienelement eine für diese Hörumgebung sinnvolle Einstellfunktion zugeordnet. Durch das betreffende Bedienelement sind damit nur noch für diese Hörsituation sinnvolle Einstellfunktionen ausführbar.The analysis of the acoustic environment in which the hearing aid is currently in a known manner by the determination of characteristic parameters, for example, concern the signal level, the modulation depth or the spectral distribution of an acoustic input signal. Depending on the detected listening environment, according to the invention, at least one control element is assigned a setting function that makes sense for this listening environment. By the relevant control element meaningful adjustment functions are thus only executable for this listening situation.

Eine Ausführungsform der Erfindung betrifft ein Hörgerätesystem mit einem Hörhilfegerät und einer als Fernbedienung ausgebildeten Bedieneinrichtung. Vorzugsweise erfolgt zwischen der Fernbedienung und dem Hörhilfegerät eine drahtlose Datenübertragung. Vorteilhaft kann dann auch die Analyse des akustischen Eingangssignals zum Ermitteln der Hörumgebung in der Fernbedienung erfolgen. Die Fernbedienung bietet zwar mehr Platz für die Anbringung von Bedienelementen als ein Hörhilfegerät, dennoch soll sie zum unauffälligen Tragen in der Hosentasche und zur Verbesserung der Übersichtlichkeit möglichst klein und nur mit wenigen Bedienelementen ausgestattet sein. Beispielsweise umfasst sie Tasten zur direkten Anwahl von vier Hörprogrammen. Gemäß der Erfindung werden dann diese vier Auswahltasten mit den zu der ermittelten Hörsituation passenden Hörprogrammen belegt, d.h., bei Betätigung einer der vier Tasten wird eines von vier zu der erkannten Hörsituation passenden Hörprogrammen im Hörhilfegerät aktiviert.One embodiment of the invention relates to a hearing aid system having a hearing aid device and a control device designed as a remote control. Preferably, wireless data transmission takes place between the remote control and the hearing aid. Advantageously, then the analysis of the acoustic input signal for determining the listening environment in the remote control done. Although the remote control provides more space for the attachment of controls than a hearing aid, yet it should be as inconspicuous carrying in the pocket and to improve clarity as small as possible and equipped with only a few controls. For example, it includes buttons for direct selection of four hearing programs. According to the invention, these four selection keys are then assigned to the hearing programs which are suitable for the hearing situation determined, that is, when one of the four keys is actuated, one of four hearing programs matching the detected auditory situation is activated in the hearing aid.

Eine Weiterbildung der Erfindung sieht vor, dass die durch den Benutzer in einer bestimmten Hörumgebung vorgenommenen manuellen Nachjustierungen des Hörhilfegerätes ausgewertet werden. Über einen längeren Zeitraum betrachtet, lernt das Hörhilfegerät somit die Präferenzen des jeweiligen Benutzers, so dass diese bei der automatischen Einstellung der die Signalverarbeitung betreffenden Parameter berücksichtigt werden können. Ein manuelles Nachjustieren wird damit immer seltener notwendig.A development of the invention provides that the manual readjustments of the hearing aid device made by the user in a specific listening environment are evaluated. Considered over a longer period of time, the hearing aid thus learns the preferences of the respective user, so that they can be taken into account in the automatic adjustment of the signal processing parameters. A manual readjustment is therefore increasingly necessary.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen erläutert. Es zeigen:

The invention will be explained below with reference to exemplary embodiments. Show it:

the block diagram of a hearing aid according to the invention and
Fig. 2
a hearing aid system with a hearing aid and a remote control.

Fig. 1 zeigt ein Hörhilfegerät im vereinfachten Blockschaltbild mit einem Mikrofon 1 zur Aufnahme eines akustischen Eingangssignals und Abgabe eines elektrischen Signals. Das elektrische Signal ist zur Verarbeitung und frequenzabhängigen Verstärkung einer Signalverarbeitungseinheit 2 zugeführt. Das verarbeitete Signal wird schließlich mittels eines Hörers 3 in ein akustisches Signal gewandelt und dem Gehör eines Hörhilfegeräteträgers zugeführt. Fig. 1 shows a hearing aid in a simplified block diagram with a microphone 1 for receiving an acoustic input signal and output of an electrical signal. The electrical signal is fed to a signal processing unit 2 for processing and frequency-dependent amplification. The processed signal is finally converted by means of a receiver 3 into an acoustic signal and fed to the hearing of a hearing aid wearer.

Das Hörhilfegerät gemäß dem Ausführungsbeispiel umfasst ferner einen Speicher 4, in dem eine Vielzahl von Parametersätzen zur Anpassung der Signalverarbeitungseinheit 2 an unterschiedliche Hörsituationen gespeichert sind. Die Auswahl eines Parametersatzes, der für die aktuelle Hörsituation die Signalverarbeitung bestimmt, kann dabei manuell oder automatisch erfolgen. Zur automatischen Auswahl umfasst das Hörhilfegerät eine Analyseeinheit 5, in der das von dem Mikrofon 1 abgegebene elektrische Signal analysiert wird. Die Analyseeinheit 5 steuert eine Auswahleinheit 6, mittels der das für die erkannte Hörsituation am besten geeignete Hörprogramm ausgewählt wird. Der entsprechende Parametersatz wird aus dem Speicher 4 ausgelesen und auf die Signalverarbeitungseinheit 2 übertragen und bestimmt damit die Signalverarbeitung. Neben dem ausgewählten Parametersatz wird gemäß der Erfindung noch eine bestimmte Anzahl weiterer Parametersätze ausgewählt, die ebenfalls sinnvolle Parametereinstellungen für die aktuelle Hörsituation beinhalten. Z.B. werden drei weitere Parametersätze ausgewählt. Bei dem Hörhilfegerät gemäß dem Ausführungsbeispiel ist die Bedieneinrichtung als Tastschalter 7 ausgebildet. Auch dieser liefert ein Signal an die Auswahleinheit 6, wobei die Auswahleinheit 6 die Auswahl auf die zu der erkannten Hörsituation passenden Parametersätze beschränkt. Durch Betätigung des Tastschalters 7 wird dann gemäß der Erfindung nur noch zwischen den insgesamt vier ausgewählten Parametersätzen umgeschaltet, in der Weise, dass ausgehend von dem automatisch eingestellten und als ersten Parametersatz bezeichneten Parametersatz zu dem nächst höheren Parametersatz umgeschaltet wird, indem dieser aus dem Speicher 4 ausgelesen und auf die Signalverarbeitungseinheit 2 übertragen wird. Die vorausgewählten Parametersätze können auf diese Weise der Reihe nach ausgewählt werden, wobei auf den vierten ausgewählten Parametersatz bei erneuter Betätigung des Tastschalters 7 wieder der erste Parametersatz folgt. Auf diese Weise bleibt die Bedienung des Hörhilfegerätes einfach und überschaubar, selbst wenn eine Vielzahl einstellbarer Parametersätze in dem Speicher 4 gespeichert ist. Beispielsweise können dort für acht unterschiedliche Hörsituationen jeweils vier Parametersätze, also insgesamt 32 Parametersätze, gespeichert sein, von denen dann nur die vier für die aktuelle Hörsituation geeigneten Parametersätze durch den Tastschalter 7 einstellbar sind. Die mit dem Tastschalter 7 ausführbare Einstellfunktion beschränkt sich in diesem Ausführungsbeispiel dann auf das Umschalten zwischen den vier für die automatisch erkannte Hörsituation sinnvollen Parametersätzen.The hearing aid device according to the exemplary embodiment further comprises a memory 4 in which a plurality of parameter sets for adapting the signal processing unit 2 to different hearing situations are stored. The selection of a parameter set, which determines the signal processing for the current hearing situation, can be done manually or automatically. For automatic selection, the hearing aid comprises an analysis unit 5, in which the electrical signal emitted by the microphone 1 is analyzed. The analysis unit 5 controls a selection unit 6 by means of which the hearing program which is most suitable for the recognized hearing situation is selected. The corresponding parameter set is read from the memory 4 and transmitted to the signal processing unit 2 and thus determines the signal processing. Next The selected parameter set according to the invention, a certain number of other parameter sets are selected, which also contain meaningful parameter settings for the current listening situation. For example, three more parameter sets are selected. In the hearing aid according to the embodiment, the operating device is designed as a key switch 7. This also supplies a signal to the selection unit 6, the selection unit 6 limiting the selection to the parameter sets which are suitable for the recognized auditory situation. By operating the key switch 7 is then switched according to the invention only between the four selected parameter sets, in such a way that is switched from the automatically set and designated as the first parameter set parameter set to the next higher parameter set by this from the memory is read out and transmitted to the signal processing unit 2. The preselected parameter sets can be selected in this way in sequence, with the fourth selected parameter set on renewed actuation of the key switch 7 again the first parameter set follows. In this way, the operation of the hearing aid remains simple and manageable, even if a plurality of adjustable parameter sets is stored in the memory 4. For example, four parameter sets, ie a total of 32 parameter sets, can be stored there for eight different listening situations, of which then only the four parameter sets suitable for the current auditory situation can be set by the push-button switch 7. The executable with the key switch 7 adjustment function is limited in this embodiment, then on the switching between the four meaningful for the automatically detected listening situation parameter sets.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass die von einem Benutzer durch Betätigung des Tastschalters 7 vorgenommenen Einstellungen für die unterschiedlichen Hörsituationen erfasst und ausgewertet werden, so dass die automatische Auswahl im Laufe der Zeit an die Benutzer-Präferenzen angepasst wird.A preferred embodiment of the invention provides that the settings made by a user by actuation of the key switch 7 for the different listening situations are detected and evaluated, so that the automatic Selection over time is adjusted to the user's preferences.

Die Parametersätze zur Steuerung der Signalverarbeitung werden vorteilhaft durch Programmierung des Hörhilfegerätes mittels einer externen Programmiereinheit (nicht dargestellt) auf das Hörhilfegerät und insbesondere in den Speicher 4 übertragen. Ferner kann durch Programmierung des Hörhilfegerätes festgelegt werden, welche Einstellfunktionen einem Bedienelement in der jeweiligen Hörsituation zugeordnet sind.The parameter sets for controlling the signal processing are advantageously transmitted to the hearing aid and in particular into the memory 4 by programming the hearing aid by means of an external programming unit (not shown). Furthermore, it can be determined by programming the hearing aid device which adjustment functions are assigned to a control element in the respective hearing situation.

Fig. 2 zeigt ein Hörgerätesystem mit einem hinter dem Ohr tragbaren Hörhilfegerät 10 und einer Fernbedienung 11. Die Fernbedienung 11 umfasst vier Programmwahltasten 12, 13, 14 und 15, durch deren Betätigung jeweils ein der jeweiligen Programmwahltaste zugeordneter Parametersatz aus einem Speicher 16 der Fernbedienung 11 ausgelesen und drahtlos auf das Hörhilfegerät 10 übertragen wird. Dieser bestimmt fortan die Signalverarbeitung in dem Hörhilfegerät 10. In dem Speicher 16 ist eine Vielzahl an Parametersätzen gespeichert, beispielsweise jeweils vier Parametersätze für acht unterschiedliche Hörsituationen. Weiterhin umfasst die Fernbedienung 11 ein Mikrofon 17 sowie eine Analyseeinheit 18, in der eine Analyse des von dem Mikrofon 17 aufgenommenen akustischen Eingangssignals erfolgt. In Folge des Analyseergebnisses werden die vier am besten für die erkannte Hörsituation geeigneten Parametersätze vorausgewählt und den Programmwahltasten 12 bis 15 zugeordnet. Bei einem Wechsel der erkannten Hörsituation wird ferner der der Programmwahltaste 1 zugeordnete Parametersatz automatisch von der Fernbedienung 11 auf das Hörhilfegerät 10 übertragen und bestimmt dadurch die Signalverarbeitung in dem Hörhilfegerät 10. Ist der Benutzer mit dieser automatisch getroffenen Einstellung unzufrieden, so kann er durch Betätigung der Programmwahltasten 13, 14 und 15 zwischen drei weiteren Hörprogrammen für diese Hörsituation wählen. Fig. 2 shows a hearing aid system with a portable behind the ear hearing aid 10 and a remote control 11. The remote control 11 includes four program selection buttons 12, 13, 14 and 15, by the operation of each one of the respective program selection button associated parameter set from a memory 16 of the remote control 11 read and wireless is transmitted to the hearing aid 10. This then determines the signal processing in the hearing aid device 10. In the memory 16 a plurality of parameter sets is stored, for example, four sets of parameters for eight different listening situations. Furthermore, the remote control 11 comprises a microphone 17 and an analysis unit 18, in which an analysis of the received from the microphone 17 acoustic input signal takes place. As a result of the analysis result, the four parameter sets which are best suited for the recognized auditory situation are preselected and assigned to the program selection keys 12 to 15. In a change of the detected hearing situation of the program selection key 1 associated parameter set is automatically transmitted from the remote control 11 to the hearing aid 10 and thereby determines the signal processing in the hearing aid 10. If the user is dissatisfied with this automatically made setting, he can by pressing the Select program selection buttons 13, 14 and 15 between three other hearing programs for this listening situation.

Die Fernbedienung 11 gemäß dem Ausführungsbeispiel umfasst weiterhin eine Schaltwippe 19, durch die in der Regel eine Veränderung der Lautstärkeneinstellung durchführbar ist. In einigen Hörsituationen wird mittels der Schaltwippe 19 jedoch eine andere Einstellfunktion als die Lautstärkeneinstellung durchgeführt. So dient die Schaltwippe 19 in der Hörsituation "Gespräch in störungsbehafteter Umgebung" zur Einstellung der Kontrastverstärkung. Der Schaltwippe 19 sind somit automatisch - in Abhängigkeit der automatisch erkannten Hörsituation - unterschiedliche Einstellfunktionen zugewiesen.The remote control 11 according to the embodiment further comprises a rocker switch 19, through which a change in the volume setting is usually feasible. In some listening situations, however, a different adjustment function than the volume adjustment is performed by means of the rocker switch 19. Thus, the rocker 19 is used in the listening situation "conversation in a noisy environment" to adjust the contrast enhancement. The switching rocker 19 are thus automatically - depending on the automatically detected hearing situation - assigned different setting functions.
