Description

Die Erfindung betrifft ein programmierbares Hörgerät, mit einem in seinen Übertragungseigenschaften zwischen Mikrofon und Hörer auf verschiedene Übertragungscharakteristika einstellbaren Verstärker- und Übertragungsteil.The invention relates to a programmable hearing aid with an amplifier and transmission part that can be adjusted in terms of its transmission properties between the microphone and the listener to different transmission characteristics.

Aus der EP 0 064 042 B1 ist eine Schaltungsanordnung für ein Hörgerät bekannt, bei dem in dem Hörgerät selbst in einem Speicher beispielsweise die Parameter für acht verschiedene Umgebungssituationen abgespeichert sind. Durch Betätigen eines Schalters wird eine erste Gruppe von Parametern abgerufen und steuert über eine Steuereinheit einen zwischen Mikrofon und Hörer eingeschalteten Signalprozessor, der dann eine erste für eine vorgesehene Umgebung bestimmte Übertragungsfunktion einstellt. Über einen Schalter können alle acht Übertragungsfunktionen nacheinander abgerufen werden, bis die gerade passende gefunden ist. Andererseits ist auch ein automatisches Umschalten zwischen fest programmierten Übertragungsfunktionen vorgesehen, wenn der Benutzer z.B. von einer geräuschvollen Umgebung in eine ruhige Umgebung kommt oder umgekehrt. Auch diese Umschaltung erfolgt zyklisch. Will man andere als die gespeicherten Übertragungsfunktionen einstellen, dann muß der nicht flüchtige Speicher durch eine externe Programmiereinheit gelöscht und durch diese erneut programmiert werden.EP 0 064 042 B1 discloses a circuit arrangement for a hearing device in which, for example, the parameters for eight different environmental situations are stored in the hearing device itself in a memory. By actuating a switch, a first group of parameters is called up and controls, via a control unit, a signal processor connected between the microphone and the receiver, which then sets a first transmission function intended for an intended environment. All eight transfer functions can be called up in succession via a switch until the right one is found. On the other hand, there is also an automatic switchover between permanently programmed transfer functions if the user e.g. comes from a noisy environment to a quiet environment or vice versa. This switchover also takes place cyclically. If you want to set other than the stored transfer functions, the non-volatile memory must be deleted by an external programming unit and re-programmed by this.

Ferner ist aus der DE 36 42 828 C2 ein fernsteuerbares, programmierbares Hörgerät bekannt, mit in seinen Übertragungseigenschaften zwischen Mikrofon und Hörer wahlweise auf verschiedene Übertragungscharakteristika einstellbarem Verstärker- und Übertragungsteil, mit einem externen Steuergerät mit einem Sender für die drahtlose Übertragung von Steuersignalen nach dem Hörgerät und einem darin befindlichen Empfänger zur Aufnahme und Demodulation von Steuersignalen. Bei diesem Hörgerät ist in den einzelnen Stufen des Übertragungskanals vom Mikrofon zum Hörer eine Basis-Übertragungscharakteristik fest eingestellt. Andere Übertragungscharakteristika sind in einem externen Steuergerät abgespeichert und können wahlweise durch Betätigen eines Schalters oder einer Drucktaste ausgewählt und mit Hilfe des in dem externen Steuergerät eingebauten Senders an den in dem Hörgerät vorgesehenen Empfänger übertragen werden. Diese von dem Hörgerät aufgenommenen Signale dienen nach Demodulation und entsprechender Verarbeitung der Einstellung einer anderen Übertragungscharakteristik des Hörgerätes zwischen Mikrofon und Hörer zur Anpassung an eine von mehreren im externen Steuergerät beispielsweise in Form von Steuerparametern digital abgespeicherten Umgebungssituationen. Diese Steuerparameter werden aus dem Audiogramm des Trägers und simulierten Umgebungssituationen ermittelt und in dem Steuergerät gespeichert. Das Audiogramm geht dabei verloren, d.h. es ist nicht mehr reproduzierbar. Das Gleiche gilt für die die Umgebungssituationen darstellenden Daten. Es ist insbesondere nicht mehr feststellbar, wie diese Steuerparameter ermittelt wurden.Furthermore, from DE 36 42 828 C2 a remotely controllable, programmable hearing aid is known, with its transmission properties between the microphone and the listener, optionally with an amplifier and transmission part that can be set to different transmission characteristics, with an external control device with a transmitter for the wireless transmission of control signals to the hearing aid and a receiver inside for recording and demodulating control signals. With this hearing aid, a basic transmission characteristic is permanently set in the individual stages of the transmission channel from the microphone to the listener. Other transmission characteristics are stored in an external control device and can be selected either by actuating a switch or a pushbutton and transmitted to the receiver provided in the hearing device with the aid of the transmitter built into the external control device. After demodulation and corresponding processing, these signals picked up by the hearing aid serve to adjust another transmission characteristic of the hearing aid between the microphone and the receiver to adapt to one of several environmental situations digitally stored in the external control device, for example in the form of control parameters. These control parameters are determined from the audiogram of the wearer and simulated environmental situations and stored in the control unit. The audiogram is lost, ie it is no longer reproducible. The same applies to the data representing the environmental situations. In particular, it is no longer possible to determine how these control parameters were determined.

Ferner ist aus der DE 32 05 685 A1 ein Hörgerät bekannt, das durch einen Träger selbst programmiert, d.h. auf seine eigene Hörbehinderung eingestellt und gegebenenfalls bei veränderter Hörbehinderung umprogrammiert, werden kann. Zu diesem Zweck kann der Hörbehinderte ein im Hörgerät in einem Speicher liegendes Testprogramm von Testtönen nacheinander abrufen und selbst bei jeweils Erreichen der Hörbarkeitsschwelle einen Schalter betätigen und damit die Speicherung eines Korrekturfaktors für den jeweiligen Testton bewirken. Nach Speicherung dieser Korrekturfaktoren errechnet ein eingebauter Mikroprozessor aus dem in einem Speicher liegenden Normalprogramm und den Korrekturfaktoren die dann gültige Übertragungscharakteristik, die so lange beibehalten wird, bis der Träger in gleicher Weise das Hörgerät umprogrammiert. Eine Anpassung an ständig wechselnde Umgebungssituationen ist dabei weder vorgesehen noch möglich, auch nicht durch Fernsteuerung.Furthermore, a hearing device is known from DE 32 05 685 A1, which can be programmed by a wearer himself, ie adjusted to his own hearing impairment and, if necessary, reprogrammed if the hearing impairment changes. For this purpose, the hearing impaired person can call up a test program of test tones stored in a memory in the memory and actuate a switch even when the audibility threshold is reached and thus cause a correction factor for the respective test tone to be stored. After storing these correction factors, a built-in microprocessor uses the normal program stored in a memory and the correction factors to calculate the then valid transmission characteristic, which is maintained until the wearer reprogrammes the hearing aid in the same way. An adjustment to Constantly changing environmental situations are neither intended nor possible, not even by remote control.

Schließlich ist aus der DE 39 00 588 C2 ein Fernsteuergerät für die drahtlose Steuerung von Hörgeräten bekannt, wobei das externe Fernsteuergerät einen ersten Speicher für die Aufnahme und Speicherung von audiometrischen Daten, einen zweiten Speicher für die Aufnahme von unterschiedlichen Umgebungssituationen kennzeichnenden Daten sowie eine datenverarbeitende Vorrichtung - für die Ermittlung der Gruppen von Steuerparametern aus den audiometrischen Daten und den die Umgebungssituation kennzeichnenden Daten gemäß einem oder mehrerer Algorithmen, die in einem dritten Speicher in Verbindung mit der datenverarbeitenden Vorrichtung gespeichert sind - enthält und wobei die den einzelnen Umgebungssituationen zugeordneten Daten jeweils aus dem zweiten Speicher mit Hilfe einer Tastatur zur Ermittlung der entsprechenden Gruppe von Steuerparametern abrufbar sind. In dem externen Steuergerät ist als datenverarbeitende Vorrichtung ein Mikroprozessor vorgesehen. Das Hörgerät ist mit den im Steuergerät berechneten Steuerparametern programmierbar und damit für eine bestimmte Umgebungssituation fest einstellbar.Finally, a remote control device for wireless control of hearing aids is known from DE 39 00 588 C2, the external remote control device having a first memory for recording and storing audiometric data, a second memory for recording data characterizing different environmental situations, and a data processing device - For the determination of the groups of control parameters from the audiometric data and the data characterizing the environmental situation according to one or more algorithms, which are stored in a third memory in connection with the data processing device - and wherein the data assigned to the individual environmental situations each from the second memory can be called up using a keyboard to determine the corresponding group of control parameters. A microprocessor is provided in the external control device as a data processing device. The hearing aid can be programmed with the control parameters calculated in the control device and can thus be permanently set for a specific environmental situation.

Aufgabe der Erfindung ist es, ein programmierbares Hörgerät zu schaffen, das eigenständig unter Berücksichtigung gespeicherter audiometrischer Daten, hörgerätespezifischer Kennwerte und vorgebbaren Algorithmen den wechselnden Umgebungssituationen anpaßbar ist.The object of the invention is to provide a programmable hearing aid which can be adapted to changing environmental situations independently, taking into account stored audiometric data, hearing device-specific characteristic values and specifiable algorithms.

Erfindungsgemäß wird diese Aufgabe bei einem programmierbaren Hörgerät gemäß Patentanspruch 1 gelöst.According to the invention, this object is achieved in a programmable hearing aid according to claim 1.

Aufgrund der ständigen Neuermittlung bzw. Neuberechnung der Einstellparameter vor Ort, d.h. im Hörgerät, ist eine ständige und kontinuierliche automatische Nachführung der Hörgeräteeinstellung an die sich möglicherweise ständig ändernden Umgebungsbedingungen möglich.Due to the constant re-determination or recalculation of the setting parameters on site, ie in the hearing aid, there is a constant and continuous automatic adjustment of the hearing aid setting possible due to the constantly changing environmental conditions.

Um in weiterer Ausbildung der Erfindung bei der Anpassung der Signalverarbeitung des Hörgerätes auch noch persönliche Daten, Anweisungen und Eindrücke des Hörgeräteträgers mit zu berücksichtigen, wird vorgeschlagen, daß in einem vierten Datenspeicher des Hörgerätes die unscharfen Eingaben des Hörgeräteträgers speicherbar sind, daß der Datenverarbeitungseinheit im Hörgerät ein Fuzzy-Logik-Modul zugeordnet ist und daß das Fuzzy-Logik-Modul aus den unscharfen Eingaben des Hörgeräteträgers, aus resultierenden Signalen aus den audiometrischen Daten, den Hörgerätekenndaten bzw. den gespeicherten Algorithmen sowie gegebenenfalls aus den Steuersignalen der Signalanalyse über die Datenverarbeitungseinheit, die aus den jeweils anliegenden Daten und Signalen ermittelten Hörgeräteeinstelldaten für das Verstärker- und Übertragungsteil bereitstellt.In order to take personal data, instructions and impressions of the hearing device wearer into account when adapting the signal processing of the hearing aid in a further embodiment of the invention, it is proposed that the fuzzy inputs of the hearing aid wearer can be stored in a fourth data memory of the hearing aid, that the data processing unit in the hearing aid a fuzzy logic module is assigned and that the fuzzy logic module from the unsharp inputs of the hearing aid wearer, from the resulting signals from the audiometric data, the hearing aid characteristics or the stored algorithms and, if appropriate, from the control signals of the signal analysis via the data processing unit provides hearing aid setting data for the amplifier and transmission part determined from the data and signals present.

Danach kann durch drahtgebundene und/oder drahtlose Übermittlung von Informationen (Daten) an das Hörgerät dessen Fuzzy-Logik optimale Einstellparameter für das Hörgerät ermitteln und dieses gemäß den im Hörgerät errechneten Einstellparametern automatisch und optimal einstellen. Im Gegensatz zu den bekannten Hörgeräte-Anpaßsystemen besteht die erfindungsgemäß übermittelte Information nicht aus direkten Einstellparametersätzen. Das erfindungsgemäße Hörgerät besitzt keine Speicher, in denen mehrere direkte Hörgeräteeinstellungen für verschiedene Umgebungssituationen gespeichert sind. Die der jeweiligen Umgebungssituation optimal angepaßte direkte Hörgeräteeinstellung ist weder im Hörgerät vorgespeichert noch wird sie übermittelt, sie wird im Hörgerät berechnet und beeinflußt direkt die Signalverarbeitung des Hörgerätes. Die drahtlos und/oder drahtgebunden übermittelte Dateninformation besteht also aus allgemeiner Information bezüglich der Umgebungsbedingungen sowie bezüglich individueller Eindrücke, Anweisungen und persönlicher Daten des Hörgeräteträgers.Then, by means of wired and / or wireless transmission of information (data) to the hearing aid, its fuzzy logic can determine optimal setting parameters for the hearing aid and automatically and optimally set them according to the setting parameters calculated in the hearing aid. In contrast to the known hearing aid fitting systems, the information transmitted according to the invention does not consist of direct setting parameter sets. The hearing aid according to the invention does not have any memories in which several direct hearing aid settings for different environmental situations are stored. The direct hearing aid setting that is optimally adapted to the respective environmental situation is neither pre-stored in the hearing aid nor is it transmitted, it is calculated in the hearing aid and directly influences the signal processing of the hearing aid. The wirelessly and / or wired data information thus consists of general information regarding the environmental conditions as well as regarding individual impressions, instructions and personal data of the hearing device wearer.

Die Bereitstellung der Informationen für die Fuzzy-Logik kann auch in einer Mischform erfolgen, d.h. die individuellen Eindrücke des Hörgeräteträgers werden mittels Fernsteuerung drahtlos an das Hörgerät übertragen, während dessen die Kriterien der herrschenden Umgebungsbedingungen automatisch im Hörgerät ermittelt werden und zusammen mit den übertragenen individuellen Eindrücken an die Fuzzy-Logik weitergereicht und dort verarbeitet werden. Die persönlichen Daten des Hörgeräteträgers können sowohl drahtlos übermittelt bzw. im Hörgerät selbst mittels Programmierung abgespeichert sein.The information for the fuzzy logic can also be provided in a mixed form, i.e. The individual impressions of the hearing aid wearer are transmitted wirelessly to the hearing aid by means of remote control, during which the criteria of the prevailing environmental conditions are automatically determined in the hearing aid and, together with the transmitted individual impressions, are passed on to the fuzzy logic and processed there. The personal data of the hearing aid wearer can be transmitted wirelessly or stored in the hearing aid itself by means of programming.

Das in Figur 1 schematisch dargestellte erfindungsgemäße Hörgerät 1 nimmt über ein Mikrofon 2 Schallsignale auf. Diese akustische Information wird im Mikrofon in elektrische Signale umgesetzt. Nach einer Signalbearbeitung in einem Verstärkungs- und Übertragungsteil 4 wird das elektrische Signal einem Hörer 3 als Ausgangswandler zugeführt. Um einen zusätzlichen Schallwandler oder einen sonstigen Sensor zu vermeiden, kann gemäß Ausführungsbeispiel aus dem Signalpfad zwischen dem Mikrofon 2 und dem Hörer 3 wenigstens eine Eingangs- oder Meßgröße 12 abgegriffen werden, die eine die jeweilige Umgebungssituation/Hörsituation kennzeichnende Größe darstellt. Das Hörgerät 1 umfaßt ferner einen ersten Datenspeicher 5, in dem die durch den Audiologen vom Hörbehinderten gemessenen audiometrischen Daten 6 speicherbar sind. Außerdem besitzt das Hörgerät einen zweiten Datenspeicher 7, in dem die vom Hörgerätehersteller vorgegebenen, hörgerätespezifischen Hörgerätekenndaten 8 speicherbar sind. Schließlich sind im Hörgerät in einem dritten Datenspeicher 9 Algorithmen 10 speicherbar, die Verarbeitungsregeln zur Ermittlung von Hörgeräteeinstelldaten 17 beinhalten. Zu den Datenspeichern enthält das Hörgerät eine Datenverarbeitungseinheit 15, z.B. einen Mikroprozessor, und eine Signalanalyseeinheit 11. In letzterer werden die Eingangsgrößen 12 analysiert und als Steuersignale 13, die die jeweilige Umgebungs-/Hörsituation kennzeichnen, der Datenverarbeitungseinheit 15 zugeführt. Durch Auswertung und Verarbeitung der Daten 6, 8 und 12, 13 sowie unter Berücksichtigung der Algorithmen 10 im Hörgerät ist das programmierbare Hörgerät gemäß der Erfindung zur kontinuierlichen, automatischen und selbständigen Anpassung seiner Übertragungscharakteristika an sich ändernde Umgebungssituationen geeignet. Im Zusammenwirken der Datenverarbeitungseinheit 15 mit der Signalanalyse 11 und den Datenspeichern 5, 7, 9 werden Steuerparameter 17 im Hörgerät errechnet bzw. ermittelt, die übertragen auf das Verstärker- und Übertragungsteil 4 die jeweilige Übertragungscharakteristik des Hörgerätes bestimmen oder mit beeinflussen.The hearing aid 1 according to the invention, shown schematically in FIG. 1, records 2 sound signals via a microphone.
