Description

Die Erfindung betrifft ein Hörgerät mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 sowie ein Verfahren zur Einstellung audiologischer/akustischer Parameter in einem Hörgerät nach dem Oberbegriff des Patentanspruchs 16.The invention relates to a hearing aid having the features of the preamble of patent claim 1 and to a method for adjusting audiological / acoustic parameters in a hearing aid according to the preamble of patent claim 16.

Als Stand der Technik sind Hörgeräte bekannt, bei denen einzelne audiologische/akustische Parameter direkt durch einzeln zugeordnete Stellglieder eingestellt werden. Das Platzangebot am Hörgerät zur Anbringung einzelner Stellgliedelemente ist jedoch begrenzt und verringert sich mit zunehmender Miniaturisierung der Hörgeräte.As prior art hearing aids are known in which individual audiological / acoustic parameters are set directly by individually associated actuators. However, the space available on the hearing aid for attachment of individual actuator elements is limited and decreases with increasing miniaturization of the hearing aids.

Der Erfindung liegt die Aufgabe zugrunde, ein Hörgerät sowie ein Verfahren zur Einstellung audiologischer/akustischer Parameter zu schaffen, wobei eine beliebige Anzahl audiologischer/akustischer Parameter über Stellglieder einstellbar ist. Die Erfindung wird bei einem Hörgerät nach Patentanspruch 1 gelöst. Vorteilhafte Ausführungsformen des Hörgeräts sind in den Unteransprüchen 2 - 9 gekennzeichnet.The invention has for its object to provide a hearing aid and a method for setting audiological / acoustic parameters, wherein any number of audiological / acoustic parameters via actuators is adjustable. The invention is achieved in a hearing aid according to claim 1. Advantageous embodiments of the hearing aid are characterized in the dependent claims 2-9.

Das zugehörige Verfahren nach der Erfindung ist durch Patentanspruch 16 gekennzeichnet. Vorteilhafte Verfahrensvarianten sind in den Unteransprüchen 17- 21 angegeben.The associated method according to the invention is characterized by claim 16. Advantageous process variants are given in the subclaims 17-21.

Das erfindungsgemäße Hörgerät weist eine Zuordnungsvorrichtung zur Zusammenfassung und/oder Ableitung audiologischer/akustischer Parameter auf, wodurch über mindestens ein Stellglied mehrere zusammengefaßte und/oder abgeleitete Parameter einstellbar sind. Hierdurch kann die Anzahl der Stellglieder am Hörgerät verringert werden, da über ein einziges Stellglied gleichzeitig mehrere entsprechend zusammengefaßte oder abgeleitete audiologische/akustische Parameter eingestellt werden können.The hearing aid according to the invention has an allocation device for combining and / or deriving audiological / acoustic parameters, whereby a plurality of combined and / or derived parameters can be set via at least one actuator. As a result, the number of actuators on the hearing aid can be reduced because a plurality of correspondingly combined or derived audiological / acoustic parameters can be set simultaneously via a single actuator.

Bei der Zusammenfassung einer entsprechend großen Anzahl von Parametern kann somit durch eine geringe Anzahl von Stellgliedern eine sehr große Anzahl von Parametern eingestellt werden.When combining a correspondingly large number of parameters, a very large number of parameters can thus be set by means of a small number of actuators.

Neben der Zusammenfassung von Parametern können auch die einzelne Parameter verknüpft werden und durch zwischengeschaltete (Rechen)-Operationen entsprechend abgeleitete Parameter ermittelt werden. Auch hierdurch kann sich die Anzahl der über die Stellglieder einstellbarer Parameter vergrößern.In addition to the summarization of parameters, the individual parameters can also be linked and determined by intermediate (rake) operations corresponding derived parameters. Also, this may increase the number of adjustable via the actuators parameters.

Das erfindungsgemäße Hörgerät ermöglicht es, über ein einziges Stellglied mehrere Parameter gleichzeitig (z.B. Gesamtverstärkung und Hochtonverstärkung) einzustellen, ohne daß hierdurch Platz für zwei Stellglieder am Hörgerät benötigt wird oder zwei einzelne Stellglieder individuell betätigt werden müssen.The hearing aid according to the invention makes it possible to set a plurality of parameters simultaneously (for example, overall amplification and high-frequency amplification) by means of a single actuator, without this requiring space for two actuators on the hearing aid or two individual actuators having to be actuated individually.

Die zuordnende Zusammenfassung und/oder Ableitung der Parameter zu den einzelnen Stellgliedern kann veränderbar sein, um aufgrund der aktuellen Hörsituation oder der sich verändernden Hörgegebenheiten des Benutzers jeweils angepaßte Gruppen zusammengefaßter und/oder abgeleiteter Parameter den jeweiligen einzelnen Stellgliedern zuzuordnen.The attributable summary and / or derivation of the parameters to the individual actuators may be changeable in order to assign matched groups of combined and / or derived parameters to the respective individual actuators on the basis of the current hearing situation or the changing auditory conditions of the user.

Bei einer programmierbaren Zuordnungsvorrichtung kann die Zuordnung der einzelnen Parameter zu den Stellgliedern auch programmgesteuert geschehen. Hierbei können benutzerspezifische Zuordnungen verwendet werden.In a programmable allocation device, the assignment of the individual parameters to the actuators can also be done programmatically. Here, user-specific assignments can be used.

In einer vorteilhaften Ausführungsform umfaßt das erfindungsgemäße Hörgerät ein Detektorelement zur Erfassung aktueller Nutz-/Störsignale. Nach einer Auswertung der erfaßten Nutz-/Störsignale können dann entsprechende an die aktuelle Hörsituation angepaßte Zusammenfassungen und/oder Ableitungen von Parametern zu den einzelnen Stellgliedern vorgenommen werden.In an advantageous embodiment, the hearing aid according to the invention comprises a detector element for detecting current useful / interference signals. After an evaluation of the detected useful / interference signals It is then possible to make corresponding summaries and / or derivations of parameters for the individual actuators that are adapted to the current auditory situation.

Falls sich der Benutzer z.B. häufig im Straßenverkehr aufhält, kann dies nach einer Feststellung durch das Detektorelement bei der Zusammenfassung der einzelnen Parameter berücksichtigt werden. In diesem Zusammenhang könnte einem einzelnen Stellglied sowohl die Gesamtverstärkung, das Tiefton-AGC-Element sowie das Hochton-AGC-Element zugeordnet werden.If the user, e.g. frequently in traffic, this may be taken into account in the summary of the individual parameters after detection by the detector element. In this regard, a single actuator could be assigned both the overall gain, the low frequency AGC element, and the high frequency AGC element.

Bei zunehmender Verstellung des Stellgliedes könnte so gleichzeitig die Grundverstärkung und die Verstärkung durch das Hochton-AGC-Element zunehmen, während gleichzeitig das Tiefton-AGC-Element (zur Ausblendung von tieffrequenten Störgeräuschen, z.B. Autolärm) zurückgenommen wird.With increasing actuator displacement, the base gain and gain from the high-frequency AGC element could increase simultaneously while the low-frequency AGC element (to eliminate low-frequency noise, e.g., car noise) is pulled back.

In Zusammenhang mit dem Detektorelement kann also eine an die spezifische Hörsituation angepaßte Zusammenfassung einzelner Parameter erfolgen, wobei gleichzeitig festgelegt wird, ob bei einer zunehmenden Verstellung des Stellgliedes die zusammengefaßten Parameter in gleichem oder unterschiedlichem Maße und in gleicher oder entgegengesetzter Richtung verstellt werden.In conjunction with the detector element can therefore be adapted to the specific situation hearing summary of individual parameters, while it is determined whether the summarized parameters are adjusted in the same or different extent and in the same or opposite direction with an increasing adjustment of the actuator.

In einer weiteren vorteilhaften Ausführungsform können die audiologischen/akustischen Parameter auch über eine externe Einheit (also nicht direkt am Hörgerät) eingestellt werden, wobei die externe Einheit über eine Kabelverbindung oder über ein Interface mit dem Hörgerät verbindbar sein kann.In a further advantageous embodiment, the audiological / acoustic parameters can also be set via an external unit (ie not directly on the hearing device), wherein the external unit can be connectable to the hearing aid via a cable connection or via an interface.

Die Einstellung über eine externe Einheit kann sich bei einer Neujustierung oder Überholung des Hörgeräts beim Akustiker oder in der Herstellerfirma als vorteilhaft erweisen, da in der externen Einheit weitere Bedienelemente und gegebenenfalls auch Zusatzprogramme integriert werden können.Adjustment via an external unit may prove to be advantageous in a readjustment or overhaul of the hearing aid at the acoustician or in the manufacturer, as in the external unit further controls and possibly also additional programs can be integrated.

Die Zuordnungsvorrichtung zur Zusammenfassung und/oder Ableitung von Parametern zu den einzelnen Stellgliedern kann im Hörgerät integriert sein oder aber auch in der externen Einheit.The allocation device for combining and / or deriving parameters from the individual actuators can be integrated in the hearing device or else in the external unit.

Die Zuordnungsvorrichtung selbst kann als Speichereinheit, vorteilhafterweise als nicht-flüchtiger Speicher, ausgeführt sein, wodurch den jeweiligen Speicheradressen mehrere und damit zusammengefaßte Parametergrößen zugeordnet werden können.The assignment device itself can be embodied as a memory unit, advantageously as a non-volatile memory, whereby the respective memory addresses can be assigned a number of parameter parameters combined with them.

Beim erfindungsgemäßen Verfahren zur Einstellung audiologischer/akustischer Parameter werden diese Parameter zunächst zusammengefaßt und/oder abgeleitet und über einige wenige Stellglieder eingestellt. Hierdurch kann durch eine geringe Anzahl von Stellgliedern eine große Anzahl von Parametern eingestellt werden.In the method according to the invention for setting audiological / acoustic parameters, these parameters are first combined and / or derived and adjusted via a few actuators. As a result, a large number of parameters can be set by a small number of actuators.

Die Zusammenfassung und/oder Ableitung der Parameter ist vorteilhafterweise veränderbar, so daß eine Anpassung an aktuelle Hörsituationen oder sich verändernde Hörgewohnheiten des Benutzers erfolgen kann.The summary and / or derivation of the parameters is advantageously variable, so that an adaptation to current listening situations or changing listening habits of the user can take place.

In einer weiteren Verfahrensvariante kann nach einer Erfassung und Auswertung aktueller Nutz-/Störsignale eine an die aktuelle Hörsituation angepaßte Zusammenfassung und/oder Ableitung von Parametern erfolgen, so daß über die vorhandenen Stellglieder eine komfortable Anpassung der Signalverarbeitung im Hörgerät an die aktuelle Hörsituation stattfinden kann.In a further variant of the method, a collection and / or derivation of parameters adapted to the current hearing situation can take place after detection and evaluation of current useful / interference signals so that a comfortable adaptation of the signal processing in the hearing device to the current auditory situation can take place via the existing actuators.

Vorteilhafterweise erfolgt eine Zusammenfassung und/oder Ableitung der Parameter der Signalverarbeitungseinrichtung bzw. von deren Elementen, und zwar insbesondere vom PC(Peak -Clipping)-Element, vom Vorverstärker, vom Trennfilter, von der Tiefton-AGC, von der Hochton-AGC, vom Hochtonverstärker und/oder vom Tieftonverstärker.Advantageously, a summary and / or derivation of the parameters of the signal processing device or of its elements, in particular from the PC (peak clipping) element, the preamplifier, the separation filter, the low-tone AGC, the high-tone AGC, from High-frequency amplifier and / or the bass amplifier.

In einem digitalen Hörgerät können vorteilhafterweise einzelne Signalverarbeitungsprozeduren zusammengefaßt und/oder abgeleitet werden, wodurch über einzelne Stellglieder gleichzeitig mehrere Signalverarbeitungsalgorithmen in der vorgenommen Verbindung und Verknüpfung aktiviert werden können.In a digital hearing aid, individual signal processing procedures can advantageously be combined and / or derived, whereby a plurality of signal processing algorithms in the connection and connection made can be activated simultaneously via individual actuators.

Vorteilhafterweise geschieht die Zuordnung der Stellglieder zu den Komponenten der Signalverarbeitungsvorrichtung über eine Speichereinheit/Decodereinheit. Die Adressen für die Speichereinheit/Decodereinheit werden durch eine Verkettung/Kombination der digitalisierten Werte der Stellglieder erzeugt. Die Datenworte, die unter diesen Adressen abgelegt sind, steuern die Signalverarbeitungsvorrichtung.Advantageously, the assignment of the actuators to the components of the signal processing device via a storage unit / decoder unit. The addresses for the memory unit / decoder unit are generated by a concatenation / combination of the digitized values of the actuators. The data words stored under these addresses control the signal processing device.

Zur Grund-/Neuprogrammierung benutzerspezifischer Parameter(-gruppen) wird bei einem Hörgerät in der oben beschriebenen Ausführung üblicherweise eine externe EDV-Einheit verwendet. Der Erfindung liegt auch die Aufgabe zugrunde, ein Hörgerät sowie ein Verfahren zur Grund-/Neuprogrammierung benutzerspezifischer Parameter(-gruppen) anzubieten, welche ohne externe EDV-Einheit auskommen.For basic / reprogramming of user-specific parameters (groups), a hearing aid in the embodiment described above usually uses an external computer unit. The invention is also based on the object of providing a hearing aid and a method for the basic / reprogramming of user-specific parameters (groups), which manage without external EDP unit.

Ein solches Hörgerät gemäß der Erfindung ist durch die Merkmale des Patentanspruchs 10 gekennzeichnet. Vorteilhafte Weiterbildungen dieses Hörgeräts sind durch die Ansprüche 11 bis 15 gekennzeichnet. Ein zugehöriges Verfahren ist durch Patentanspruch 22 und die darauf bezogenen Ansprüche 23 bis 25 gekennzeichnet.Such a hearing aid according to the invention is characterized by the features of claim 10. Advantageous developments of this hearing aid are characterized by the claims 11 to 15. An associated method is characterized by claim 22 and the claims 23 to 25 related thereto.

Das gemäß den Ansprüchen 10-15 ausgeführte Hörgerät besitzt einen integrierten Generator mit einer Generatorsteuerung. Bei der Grund-/Neuprogrammierung des Hörgeräts können über diesen Generator Tonsignale, Rauschsignale oder Rauschimpulssignale erzeugt werden. Bei der "In-situ-programmierung" kann der Benutzer gegenüber dem Akustiker anzeigen, wann vom Akustiker durch Betätigung von Stellelementen erzeugte Signale gehört und/oder als angenehm empfunden werden.The hearing aid embodied according to claims 10-15 has an integrated generator with a generator control. During basic / reprogramming of the hearing aid, sound signals, noise signals or noise pulse signals can be generated via this generator. In "in-situ programming," the user can indicate to the acoustician when the acoustician is to be operated by Control elements generated signals heard and / or perceived as pleasant.

Hierdurch können schrittweise benutzerspezifischer Parameter(-gruppen) zur Signalverarbeitung im Hörgerät (z.B. Verstärkung in den einzelnen Kanälen, AGC-Einstellungen, Dynamikwerte, Unbehaglichkeitsschwellen etc.) eingestellt werden. Die "In-situ-Programmierung" findet unter Abschaltung des Mikrofons des Hörgeräts statt.This allows user-specific parameters (groups) to be adjusted for signal processing in the hearing aid (e.g., gain in each channel, AGC settings, dynamics, discomfort thresholds, etc.). The "in situ programming" takes place with switching off the microphone of the hearing aid.

Durch den eingebauten Generator des Hörgeräts kann auf einer externen EDV-Einheit zur Einspielung von Einstellungsprogrammen in das Hörgerät bei der Grund-/Neuprogrammierung verzichtet werden. Damit wird eine Einstellung benutzerspezifischer Parameter(-gruppen) besonders dann erleichtert, wenn eine derartige EDV-Einheit aus Kostengründen (z.B. in Entwicklungsländern) nicht verfügbar ist.The built-in generator of the hearing aid can be dispensed with on an external computer unit for recording adjustment programs in the hearing aid in the basic / reprogramming. This facilitates an adjustment of user-specific parameters (groups), especially if such a computer unit is not available for cost reasons (for example in developing countries).

Vorteilhafterweise ist eine externe Einheit zur Grund-/Neuprogrammierung des Hörgeräts vorgesehen, über welche vom Akustiker weitere Stellglieder ("Trimmer") und das Steuerelement für die Generatorsteuerung betätigt werden. Zusätzlich kann das erfindungsgemäße Hörgerät eine Programmierbuchse aufweisen, um auch eine (ergänzende) Programmierung durch eine externe EDV-Einheit zu ermöglichen.Advantageously, an external unit for basic / reprogramming of the hearing aid is provided, via which the acoustician actuates further actuators ("trimmers") and the control element for the generator control. In addition, the hearing aid according to the invention can have a programming socket in order to also enable (supplementary) programming by an external EDP unit.

Ein wesentlicher Vorteil dieser Ausführung besteht darin, daß der Akustiker ohne Verwendung einer externen EDV-Einheit über einige wenige Stellelemente verschiedene und in ihrer Zuordnung veränderbare Parametergruppen berechnen und/oder einstellen kann. Nach dem zugehörigen Verfahren findet eine Grund-/Neuprogrammierung benutzerspezifischer Parameter(-gruppen) über einige wenige Stellglieder über einen ins Hörgerät integrierten Generator mit Generatorsteuerung statt. Über den Generator werden unterschiedliche Signale und Pegel erzeugt, welche vom Benutzer als hörbar und/oder behaglich eingestuft werden. Daraufhin können die bereits erwähnten benutzerspezifischen Parameter(-gruppen) und Kennwerte schrittweise zur Grund-/Neuprogrammierung am Hörgerät eingestellt werden.An essential advantage of this embodiment is that the acoustician can calculate and / or set different parameter groups which can be changed in their assignment without the use of an external EDP unit via a few control elements. According to the associated method, a basic / reprogramming of user-specific parameters (groups) takes place via a few actuators via a generator with generator control integrated into the hearing aid. About the generator different signals and levels are generated, which are classified by the user as audible and / or comfortable. Thereupon, the already mentioned user-specific Parameters (groups) and characteristics are set step by step to the basic / reprogramming on the hearing aid.

Vorteilhafterweise erfolgt eine Einstellung der Kennwerte und Parameter schrittweise bei verschiedenen Pegeln des Generatorsignals. Über eine externe Einheit kann weiterhin ohne externe EDV-Einheit eine zusammengefaßte und gebündelte Anordnung und Einstellung von Stellelgliedern und Steuerelementen für den Generator zur Grund-/Neuprogrammierung verwirklicht werden.Advantageously, an adjustment of the characteristic values and parameters takes place stepwise at different levels of the generator signal. Via an external unit, it is also possible, without an external computer unit, to implement a combined arrangement and arrangement of control elements and controls for the generator for basic / reprogramming.

Zusätzlich ermöglicht das erfindungsgemäße Verfahren auch über eine Programmierbuchse eine Grund-/Neuprogrammierung über eine anschließbare externe EDV-Einheit.In addition, the method according to the invention also enables a basic / reprogramming via a programmable socket via a connectable external EDP unit.

Die Erfindung ist anhand von Ausführungsbeispielen in den Zeichnungsfiguren näher erläutert. Es zeigen:

FIG 1 zeigt ein Hörgerät mit einem Mikrofon 1, einer Signalverarbeitungseinrichtung 17 und einem Lautsprecher 20. In der Signalverarbeitungseinrichtung 17 sind einzelne Signalverarbeitungselemente beispielhaft aufgeführt, nämlich ein PC-Element 2 (Peak-Clipping-Element), ein Vorverstärker 3, ein Trennfilter 4, eine Tiefton-AGC 5, eine Output-AGC 6, eine Hochton-AGC 7 sowie ein Hochtonverstärker 8 und ein Tieftonverstärker 9.1 shows a hearing device with a microphone 1, a signal processing device 17 and a loudspeaker 20. In the signal processing device 17, individual signal processing elements are exemplified, namely a PC element 2 (peak clipping element), a preamplifier 3, a separation filter 4, a woofer AGC 5, an output AGC 6, a tweeter AGC 7, and a tweeter amplifier 8 and a woofer amplifier 9.

Ferner weist das Hörgerät eine Zuordnungsvorrichtung 16 zur Zusammenfassung und/oder Ableitung audiologischer/akustischer Parameter der genannten Elemente 2 - 9 der Signalverarbeitung 17 auf.Furthermore, the hearing device has an assignment device 16 for combining and / or deriving audiological / acoustic parameters of the elements 2 - 9 of the signal processing 17.

Die Ausgangskontakte A1 - A8 sind zur Ansteuerung direkt mit den einzelnen genannten Elementen 2 - 9 verbunden. Über die Zuordnungsvorrichtung 16 können nun die Ausgangskontakte A1 - A8 der Signalverarbeitungsvorrichtung 17 individuell und grundsätzlich beliebig mit den Eingangskontakten E1 - E4 der Zuordnungsvorrichtung 16 und damit mit deren Stellgliedern 10 - 13 verbunden werden.The output contacts A1 - A8 are connected to the control directly to the individual elements 2 - 9 mentioned. Via the assignment device 16, the output contacts A1 - A8 of the signal processing device 17 can now be connected to the input contacts E1 - E4 of the assignment device 16 and thus to their actuators 10 - 13 individually and in principle as desired.

Aus FIG 1 geht hervor, daß die Ausgänge A1, A4, A5 mit dem Eingang E1, die Ausgänge A2 und A6 mit dem Eingang E3, Ausgang A3 mit dem Eingang E2 sowie die Ausgänge A6, A7, A8 mit dem Eingang E4 der Zuordnungsvorrichtung 16 verbunden sind.1 shows that the outputs A1, A4, A5 to the input E1, the outputs A2 and A6 to the input E3, output A3 to the input E2 and the outputs A6, A7, A8 to the input E4 of the assignment device 16th are connected.

Bei Betätigung des Stellgliedes 10 erfolgt somit gleichzeitig eine Aktivierung der mit den Ausgängen A1, A4, A5 verbundenen Elemente der Signalverarbeitungsvorrichtung 17.Upon actuation of the actuator 10 thus takes place at the same time an activation of the connected to the outputs A1, A4, A5 elements of the signal processing device 17th

Die Zuordnung zwischen den Ausgängen A und Eingängen E ist veränderbar und kann an aktuelle Hörsituationen oder Benutzerwünsche angepaßt werden. Es können auch einzelne Ausgänge A nur mit einem einzigen Eingang verbunden sein (z.B. Verbindung A2 - E3) oder einzelne Ausgänge mit mehreren Eingängen verbunden sein (z.B. A6 mit E3 und E4).The assignment between the outputs A and inputs E is changeable and can be adapted to current listening situations or user requests. Also, individual outputs A may be connected to only a single input (e.g., connection A2 - E3) or individual outputs may be connected to multiple inputs (e.g., A6 with E3 and E4).

Generell kann durch die Zuordnungsvorrichtung 16 nicht nur eine Verbindung zwischen Ausgängen A und Eingängen E erfolgen, sondern können auch den Ausgängen A zugeordnete audiologische/akustische Parameter durch weitere (Rechen-)Operationen, z.B. gewichtet, gemittelt oder anderweitig bearbeitet werden, bevor eine Zusammenfassung der sich ergebenden abgeleiteten Parameter erfolgt.In general, not only can a connection between outputs A and inputs E take place through the assignment device 16, but also audiological / acoustic parameters associated with the outputs A may be processed by further (arithmetic) operations, eg weighted, averaged or otherwise, before a summary of the resulting derived parameters is made.

Das Hörgerät kann neben den Stellgliedern 10 - 13 noch weitere Bedienelemente 14, 15 aufweisen.The hearing aid may have, in addition to the actuators 10-13, further control elements 14, 15.

Über das Detektorelement 18 können aktuelle Nutz-/Störsignale aufgenommen werden und die Zuordnung zwischen den Ausgängen A und den Eingängen E kann an die aktuelle Hörsituation angepaßt werden.Current useful / interference signals can be recorded via the detector element 18 and the association between the outputs A and the inputs E can be adapted to the current listening situation.

FIG 2 zeigt ein Hörgerät mit einer in eine externe Einheit 19 integrierten Zuordnungsvorrichtung 16. Im Gegensatz zu FIG 1 ist die Zuordnungsvorrichtung 16 somit nicht im Hörgerät integriert.FIG. 2 shows a hearing device with an assignment device 16 integrated into an external unit 19. In contrast to FIG. 1, the assignment device 16 is thus not integrated in the hearing device.

Über die Stellglieder 10 - 13 kann z.B. der Akustiker über die externe Einheit 19 eine entsprechende Zusammenfassung und/oder Ableitung der audiologischen/akustischen Parameter vornehmen und über gegebenenfalls in die externe Einheit 19 integrierte weitere Bedienelemente sowie EDV-Programme (nicht abgebildet) eine umfassende Zusammenfassung und/oder Ableitung audiologischer/akustischer Parameter des Hörgeräts durchführen.Via the actuators 10-13, e.g. the acoustician via the external unit 19 make a corresponding summary and / or derivation of the audiological / acoustic parameters and optionally integrated in the external unit 19 further controls and computer programs (not shown) a comprehensive summary and / or derivative of audiological / acoustic parameters of the hearing aid.

FIG 3 zeigt eine externe Einheit 19 mit Stellgliedern 10 - 13 zur Einstellung von in einer hörgerätinternen Zuordnungsvorrichtung 16 an den Eingängen E1 - E4 zusammengefaßten und/oder abgeleiteten Parametern der Ausgänge A1 - A8, die jeweils direkt mit einem der Elemente 2 - 9 der Signalverarbeitungsvorrichtung 17 verbunden sind. Die externe Einheit 19 weist keine Zuordnungsvorrichtung 16 auf und kann demnach kompakt ausgebildet werden. Im Vergleich zur hörgerätinternen Anbringung der Stellglieder 10 - 13 ergeben sich jedoch durch die externe Einheit 19 weitere Möglichkeiten in der Anbringung zusätzlicher Stellglieder oder sonstiger Bedienelemente, um die in der Zuordnungsvorrichtung 16 zusammengefaßten und/oder abgeleiteten audiologischer/akustischer Parameter individuell einstellen zu können.FIG. 3 shows an external unit 19 with actuators 10-13 for setting parameters of the outputs A1-A8, which are combined and / or derived in the inputs E1-E4 in a hearing device-internal assignment device 16, each directly connected to one of the elements 2-9 of the signal processing device 17 are connected. The external unit 19 has no allocation device 16 and can therefore be made compact. Compared to the hearing aid attachment of the actuators 10 - 13 arise, however, by the external unit 19 further possibilities in the attachment of additional actuators or other controls in order to set the combined in the assignment device 16 and / or derived audiological / acoustic parameters individually.

Hierbei werden dem Benutzer über die externe Einheit 19 z.B. virtuelle/visuelle Steller angeboten. Die Zusammenfassung und Ableitung der Parameter wird dabei in der externen Einheit 19 vollzogen.Here, the user is informed via the external unit 19 e.g. Virtual / Visual Steller offered. The summary and derivation of the parameters is performed in the external unit 19.

Figur 4 zeigt ein Hörgerät mit einem Mikrofon 1, einer Signalverarbeitungseinrichtung 17 und einem Lautsprecher 20. Eine Signalverarbeitungseinrichtung 17 des Hörgerätes umfaßt ein PC-Element 2 ("peak-clipping-element"), einen Vorverstärker 3, ein Trennfilter 4, eine Tiefton-AGC 5, eine Output-AGC 6, eine Hochton-AGC 7, einen Hochton-Verstärker 8 und einen Tiefton-Verstärker 9. Ausgangskontakte A1 - A8 sind zur Ansteuerung direkt mit den genannten Bauelementen 2 - 9 verbunden (nicht abgebildet).4 shows a hearing device with a microphone 1, a signal processing device 17 and a loudspeaker 20. A signal processing device 17 of the hearing device comprises a PC element 2 (peak-clipping element), a preamplifier 3, a separation filter 4, a woofer AGC 5, an output AGC 6, a tweeter AGC 7, a tweeter amplifier 8 and a woofer amplifier 9. Output contacts A1 - A8 are connected directly to said components 2-9 (not shown) for driving purposes.

Über eine Zuordnungsvorrichtung 16 können die Ausgangskontakte A1 - A8 der Signalverarbeitungseinrichtung 17 individuell und grundsätzlich beliebig mit Eingangskontakten E1 - E4 der Zuordnungsvorrichtung 16 und damit mit deren Stellgliedern 10, 11 und mittelbar mit Stellgliedern 12, 13 der externen Einheit 19 verbunden werden. Das Hörgerät weist noch weitere Bedienelemente 14 und 15 auf. Ein Detektorelement 18 kann aktuelle Nutz-/Störsignale aufnehmen, so daß die Zuordnung zwischen den Ausgängen A und den Eingängen E an eine aktuelle Hörsituation anpaßbar ist. Das erfindungsgemäße Hörgerät weist einen Generator 21 mit einer Generatorsteuerung 22 auf, die über den Ausgang A9 mit dem Steuerelement 24 verbunden ist.Via an assignment device 16, the output contacts A1-A8 of the signal processing device 17 can be connected individually and basically arbitrarily with input contacts E1-E4 of the assignment device 16 and thus with their actuators 10, 11 and indirectly with actuators 12, 13 of the external unit 19. The hearing aid has even more control elements 14 and 15. A detector element 18 can record current useful / interference signals, so that the association between the outputs A and the inputs E can be adapted to a current hearing situation. The hearing aid according to the invention has a generator 21 with a generator control 22 which is connected to the control 24 via the output A9.

Bei der "In-situ-programmierung" wird das Mikrofon 1 abgeschaltet und es werden über den Generator 21 Tonsignale, Rauschsignale oder Rauschimpulssignale bei einem bestimmten über das Steuerelement 24 eingestellten Generatorpegel erzeugt.In the "in-situ programming" the microphone 1 is turned off and there are 21 sound signals, Noise signals or noise pulse signals generated at a certain set via the control element 24 generator level.

Der Akustiker kann nun durch schrittweise Verstellung der Stellglieder 12 oder 13 das anliegende Generatorsignal verändern. Durch Rückäußerung kann der Benutzer zu erkennen geben, ob das Signal hörbar ist oder als (un-)behaglich empfunden wird. Wenn dies der Fall ist, können die entsprechenden Parameter(-gruppen), z.B. Verstärkung in den einzelnen Kanälen, AGC-Einstellungen, Dynamikwerte, Unbehaglichkeitsschwelle etc., festgehalten und abgespeichert oder über vorliegende Algorithmen berechnet und abgespeichert werden.The acoustician can now change the applied generator signal by stepwise adjustment of the actuators 12 or 13. By re-expressing the user can indicate whether the signal is audible or perceived as (un) comfortable. If this is the case, the corresponding parameters (groups), e.g. Gain in the individual channels, AGC settings, dynamic values, discomfort threshold, etc., recorded and stored or calculated and stored using existing algorithms.

Schrittweise werden nun bei unterschiedlichen über das Steuerelement 24 eingestellten Generatorsignalpegeln über die Stellelemente 12, 13 sämtliche benutzerspezifische Parameter(-gruppen) des Hörgeräts unter ständiger Rückäußerung vom Benutzer gegenüber dem Akustiker eingestellt. Eine externe EDV-Einheit wird hierzu nicht gebraucht.Step by step, all user-specific parameters (groups) of the hearing aid are now set by the user with respect to the acoustician at different generator signal levels set via the control element 24 via the adjusting elements 12, 13 with constant feedback. An external computer unit is not needed for this purpose.

Durch einige wenige Stellglieder, z.B. die Stellglieder 12, 13, können mit der Zuordnungsvorrichtung 16 Gruppen von Parametern berechnet und/oder eingestellt werden. Hierdurch wird die Anzahl der zur Grund-/Neuprogrammierung benötigten Stellglieder reduziert und seine Bedienungsfreundlichkeit verbessert. Falls gewünscht oder notwendig, kann eine externe EDV-Einheit über eine Programmierbuchse 23 zur (ergänzenden) Programmierung an die Signalverarbeitungseinrichtung 17 angeschlossen werden.By a few actuators, e.g. the actuators 12, 13, can be calculated and / or adjusted with the allocation device 16 groups of parameters. This reduces the number of actuators needed for basic / reprogramming and improves its ease of use. If desired or necessary, an external computer unit can be connected to the signal processing device 17 via a programming socket 23 for (supplementary) programming.
