Description

Die Erfindung bezieht sich auf ein am Kopf tragbares Hörgerät, umfassend einen elektrischen Signalweg zwischen einem Mikrofon und einem Hörer, wobei der Signalweg unter Verwendung von Mitteln zur elektronischen Einstellung vorprogrammierbarer Übertragungsparameter und eines Schaltmittels des Hörgerätes an verschiedene Hörsituationen/Schallumgebungen anpaßbar ist.The invention relates to a hearing aid that can be worn on the head, comprising an electrical signal path between a microphone and a receiver, the signal path being adaptable to different hearing situations / sound environments using means for electronically setting preprogrammable transmission parameters and a switching means of the hearing aid.

Aus der EP-B-0 064 042 ist ein Hörgerät der eingangs genannten Art bekannt. Der Signalweg zwischen Mikrofon und Hörer wird durch vorprogrammierte Übertragungsparameter von einem Schaltmittel des Hörgerätes an verschiedene Schallumgebungen oder Hörsituationen angepaßt. Das Schaltmittel kann manuell betätigbar oder als automatisch arbeitende Schaltung ausgebildet sein. Bei manueller Betätigung des Schaltmittels muß sich der Benutzer des bekannten Hörgerätes jeweils merken, welches Programm am Hörgerät eingestellt ist.A hearing aid of the type mentioned at the outset is known from EP-B-0 064 042. The signal path between the microphone and the listener is adapted to different sound environments or listening situations by means of preprogrammed transmission parameters from a switching device of the hearing device. The switching means can be operated manually or can be designed as an automatically operating circuit. When the switching means is operated manually, the user of the known hearing device must remember which program is set on the hearing device.

Die ältere EP-A-0 480 097 geht davon aus, daß jeder Hörgerätehersteller eine große Typenvielfalt von Hörgeräten in seinem Programm anbietet. Selbst Hörgeräte mit baugleichem Gehäuse können sich durch unterschiedliche Einbauteile, wie Mikrofon, Hörer und/oder elektrische Verstärkerschaltungen, aufgrund unterschiedlicher Leistungsdaten dieser Einbauteile des Hörgerätes erheblich voneinander unterscheiden. Bei der Auswahl eines Hörgerätes für einen Hörbehinderten muß deshalb der Audiologe oftmals zeitaufwendige Untersuchungen der Hörgeräte vornehmen, um anhand von gesonderten Datenlisten des Herstellers den jeweiligen Hörgerätetyp ermitteln zu können. Solche Datenlisten müssen andererseits vom Hersteller stets auf dem neuesten Stand gehalten werden, was für den Hersteller einen gewissen Aufwand bedeutet. Gelegentlich sind die beim Audiologen vorhandenen Datenlisten schon veraltet. Folglich müssen dann zur genauen Feststellung von Hörgerätemerkmalen zeitaufwendige Messungen am Hörgerät durchgeführt werden. Deshalb soll der Vorschlag der EP-A-0 480 097 dazu dienen, dem Audiologen wie auch dem Hersteller die Feststellung detaillierter Hörgeräte-Baumerkmale zu erleichtern. Die EP-A-0 480 097 schlägt hierzu vor, daß in einem Datenspeicher des Hörgerätes durch den Hörgerätehersteller die Hörgeräte-Baumerkmale gespeichert sind, die später zur Identifizierung des Hörgerätetyps durch den Audiologen/Hersteller aus dem Datenspeicher auslesbar sind. Dabei kann ein Fernsteuerteil mit Begrenzerstufe, z.B. als Schmitt-Trigger mit vorgeschaltetem Hochpaßfilter, sowie eine Auswerteschaltung und ein Datendekoder vorgesehen sein, derart, daß von einem Fernsteuersender abgegebene Fernsteuersignale, die das Mikrofon empfängt, im Datendekoder dekodiert und einem Speicher zugeführt werden. Andererseits können aus dem Datenspeicher, über den Dekoder und den Hörer sowie einen externen Empfänger die technischen Hörgerätekenndaten ausgelesen werden.The older EP-A-0 480 097 assumes that every hearing aid manufacturer offers a wide variety of hearing aids in its program. Even hearing aids with an identical housing can differ considerably from one another due to different built-in parts, such as a microphone, receiver and / or electrical amplifier circuits, due to different performance data of these built-in parts of the hearing aid. When selecting a hearing aid for a hearing impaired person, the audiologist must therefore often carry out time-consuming examinations of the hearing aids in order to be able to determine the respective hearing aid type on the basis of separate data lists from the manufacturer. On the other hand, such data lists must always be kept up to date by the manufacturer, which means a certain effort for the manufacturer. Occasionally, the data lists available at the audiologist are already out of date. Consequently, time-consuming measurements must then be carried out on the hearing aid in order to precisely determine hearing aid features. Therefore, the proposal of EP-A-0 480 097 should serve to make it easier for the audiologist and the manufacturer to determine detailed hearing device construction features. EP-A-0 480 097 suggests that the hearing device manufacturer stores the hearing device construction features in a data memory of the hearing device which can later be read out from the data memory for identification of the hearing device type by the audiologist / manufacturer. A remote control part with a limiter stage, e.g. as a Schmitt trigger with an upstream high-pass filter, as well as an evaluation circuit and a data decoder can be provided such that remote control signals emitted by a remote control transmitter and received by the microphone are decoded in the data decoder and fed to a memory. On the other hand, the technical hearing aid characteristic data can be read out of the data memory, via the decoder and the handset as well as an external receiver.

Mit der Erfindung wurde erkannt, daß der Hörbehinderte während der Benutzung des Hörgerätes weder das am Kopf tragbare Hörgerät noch eine gegebenenfalls vorhandene Markierung der Schaltposition des manuell betätigbaren Programmwahlschalters am Hörgerät sehen kann. Die Schallumgebungen und/oder Hörsituationen ändern sich aber recht häufig, so daß der Benutzer des Hörgerätes die zuletzt gewählte Einstellung leicht vergessen kann. Wenn der Benutzer nun die gewählte Einstellung des Hörgerätes feststellen will, muß er entweder das Hörgerät vom Kopf abnehmen und das gewählte Programm aufgrund der Markierung der Schaltposition bestimmen oder den Signalübertragungsweg des Hörgerätes zunächst in eine Grundstellung schalten und von dieser Grundstellung ausgehend bis zu der gewünschten Einstellung weiterschalten. Ein derartiges Vorgehen ist sehr zeitaufwendig und umständlich. Insbesondere ältere Benutzer eines Hörgerätes können dadurch überfordert sein. Wenn die Programmauswahl durch eine automatisch arbeitende Schaltung erfolgt, erhält der Benutzer gar keine Information über das jeweils automatisch gewählte Programm bzw. über den automatisch gewählten Übertragungsparameter.With the invention it was recognized that the hearing impaired can see neither the hearing aid that can be worn on the head nor any marking of the switching position of the manually operated program selector switch on the hearing aid while the hearing aid is in use. The sound environments and / or listening situations change quite frequently, however, so that the user of the hearing aid can easily forget the last selected setting. If the user now wants to determine the selected setting of the hearing aid, he must either remove the hearing aid from the head and determine the selected program based on the marking of the switching position or first switch the signal transmission path of the hearing aid into a basic position and starting from this basic position up to the desired setting switch on. Such a procedure is very time-consuming and cumbersome. Older users of a hearing aid in particular can be overwhelmed by this. If the program is selected by an automatically operating circuit, the user receives no information at all via the automatically selected program or via the automatically selected transmission parameter.

Aufgabe der Erfindung ist es, bei einem Hörgerät, das ein Schaltmittel aufweist, mittels dem durch Wahl von Übertragungsparametern eine Anpassung des Hörgerätes an unterschiedliche Hörsituationen möglich ist, dem Hörbehinderten das Erkennen des jeweils gewählten Übertragungsparameters zu erleichtern.The object of the invention is to make it easier for the hearing impaired to recognize the respectively selected transmission parameter in a hearing aid which has a switching means by means of which the hearing aid can be adapted to different hearing situations by selecting transmission parameters.

Diese Aufgabe wird durch ein Hörgerät mit den Merkmalen des Anspruches 1 gelöst. Erfindungsgemäß wird mit dem Schaltmittel zum Einstellen eines Übertragungsparameters des Signalweges (Anpassung an die jeweilige Hörsituation und/oder Schallumgebung) zusätzlich eine Signalabgabeeinrichtung gesteuert, die wenigstens ein Signal abgibt, das für jeden elektronisch ein gestellten Übertragungsparameter charakteristisch ist.This object is achieved by a hearing aid with the features of claim 1. According to the invention, the switching means for setting a transmission parameter of the signal path (adaptation to the respective listening situation and / or sound environment) additionally controls a signal output device which emits at least one signal which is characteristic of each electronically set transmission parameter.

Das Signal kann in beliebiger Art abgegeben werden. Besonders vorteilhaft ist es, wenn das Signal akustisch von dem Benutzer des Hörgerätes wahrnehmbar ist. Dazu kann die Signalabgabeeinrichtung als Tonfrequenzgenerator ausgebildet sein, der an den Signalweg zwischen dem Mikrofon und dem Hörer wenigstens ein elektrisches Signal abgibt, das für jeden elektronisch eingestellten Übertragungsparameter charakteristisch ist. Dadurch gelangt über den Hörer des Hörgerätes das vom Tonfrequenzgenerator abgegebene elektrische Signal als akustisches Signal in das Ohr des Hörgerätebenutzers. Der Hörgerätebenutzer kann dieses akustische Signal wahrnehmen, ohne das Hörgerät vom Kopf abnehmen zu müssen.The signal can be given in any way. It when the signal is audible by the user of the hearing aid is particularly advantageous. For this purpose, the signal output device can be designed as an audio frequency generator, which outputs at least one electrical signal to the signal path between the microphone and the listener, which is characteristic of each electronically set transmission parameter. As a result, the electrical signal emitted by the audio frequency generator reaches the ear of the hearing device user as an acoustic signal via the receiver of the hearing device. The hearing aid user can perceive this acoustic signal without having to remove the hearing aid from the head.

Das von dem Tonfrequenzgenerator über den Hörer abgegebene Signal kann in einfachster Weise als Pfeifton abgegeben werden, der bei einer ersten Parametereinstellung z.B. nur einmal, bei einer zweiten Parametereinstellung z.B. zweimal und schließlich bei einer n-ten Parametereinstellung z.B. n-mal mit beispielsweise gleicher Frequenz abgegeben wird. Dadurch erhält der Benutzer des Hörgerätes bei jeder Parameterumschaltung durch das Schaltmittel über den Hörer des Hörgerätes ohne eigenes Zutun (also automatisch) eine Information über den sonach eingeschalteten Übertragungsparameter. Das Schaltmittel für die Programmwahl/Parametereinstellung kann als manuell betätigbares oder als automatisch arbeitendes Schaltmittel ausgebildet sein.The signal emitted by the audio frequency generator via the receiver can be emitted in the simplest way as a whistle. which is emitted, for example, only once for a first parameter setting, for example twice for a second parameter setting, and finally, for example n times with an identical frequency, for an nth parameter setting. As a result, the user of the hearing device receives information about the transmission parameter that is switched on each time the switch means changes parameters via the receiver of the hearing device without any action on his part. The switching means for program selection / parameter setting can be designed as a manually operable or as an automatically operating switching means.

In Ausbildung der Erfindung ist es besonders vorteilhaft, wenn die Wirkung des manuell betätigbaren Schaltmittels auf die Signalabgabeeinrichtung und/oder auf das Mittel zur elektronischen Parametereinstellung über eine Zeitschaltung steuerbar ist. Die Steuerung kann dabei derart erfolgen, daß bei einer ersten Betätigung des Schaltmittels innerhalb eines vorgebbaren Zeitraumes nur die Signalabgabeeinrichtung eingeschaltet wird. Dadurch erhält der Benutzer des Hörgerätes zunächst eine Information über den bereits eingeschalteten Übertragungsparameter. Wird danach das Schaltmittel innerhalb einer vorgebbaren Zeitdauer nochmals betätigt, wird ein neuer Übertragungsparameter elektronisch eingestellt und diese neue Einstellung durch Abgabe eines anderen Signals aus der Signalabgabeeinrichtung bestätigt.In an embodiment of the invention, it is particularly advantageous if the effect of the manually operable switching means on the signal output device and / or on the means for electronic parameter setting can be controlled via a time switch. The control can take place in such a way that when the switching means is actuated for the first time within a predeterminable period of time, only the signal output device is switched on. As a result, the user of the hearing aid initially receives information about the transmission parameter that has already been switched on. If the switching means is then actuated again within a predefinable period of time, a new transmission parameter is set electronically and this new setting is confirmed by emitting another signal from the signal output device.

Der Benutzer des Hörgerätes kann sonach jederzeit eine Information über den gerade eingestellten Übertragungsparameter abrufen. Des weiteren erhält der Benutzer bei nochmaliger Betätigung des Schaltmittels für die Programmwahl/Parametereinstellung ein anderes Signal, das z.B. den anderen sodann eingestellten Übertragungsparameter charakterisiert und außerdem als Bestätigung dafür dient, daß der andere Parameter tatsächlich eingestellt worden ist. Dadurch sind Fehlbedienungen insbesondere durch ältere Benutzer von Hörgeräten vermeidbar, wenn das manuell betätigbare Schaltmittel zur Einstellung eines Hörgeräteparameters zwar berührt, aber dennoch nicht so ausreichend betätigt wird, daß eine Umschaltung auf ein z.B. anderes Signalverarbeitungsprogramm erfolgt.The user of the hearing aid can therefore call up information about the transmission parameter just set at any time. Furthermore, when the switching means for the program selection / parameter setting is actuated again, the user receives another signal which, for example, characterizes the other transmission parameter then set and also serves as confirmation that the other parameter has actually been set. This makes incorrect operations in particular Avoidable by older users of hearing aids if the manually operable switching means for setting a hearing device parameter touches, but is nevertheless not actuated sufficiently to switch to a different signal processing program, for example.

Nach einer weiteren Ausgestaltung der Erfindung ist die Signalabgabeeinrichtung als Sprachgenerator ausgebildet. Dadurch kann ein Sprachsignal, das z.B. die Worte "erstes Programm" abgibt, über den Hörer des Hörgerätes als unmittelbare Information über die gewählte Einstellung des Hörgerätes dem Benutzer des Hörgerätes zugänglich gemacht werden.According to a further embodiment of the invention, the signal output device is designed as a speech generator. This enables a speech signal, e.g. emits the words "first program" through which the hearing aid of the hearing aid is made available to the user of the hearing aid as immediate information about the selected setting of the hearing aid.

For this purpose, the electronic setting means 4 can be preprogrammed. By actuating the manually adjustable switching means 5 or by responding (taking effect) of the automatically acting switching means 5 ', pre-programmed settings of transmission parameters in the signal transmission path 1 are then triggered in a manner known per se.

Bei dem erfindungsgemäß ausgebildeten Hörgerät 6 wirkt das manuelle Schaltmittel 5 bzw. das automatische Schaltmittel 5′ zusätzlich noch auf eine Signalabgabeeinrichtung ein, die als Tonfrequenzgenerator 7 ausgebildet ist. Die Einwirkung kann derart geschehen, daß bei der Einschaltung eines Übertragungsparameters zugleich der Tonfrequenzgenerator 7 z.B. kurzzeitig eingeschaltet wird. Während der Dauer der Einschaltung des Tonfrequenzgenerators 7 wird von diesem wenigstens ein elektrisches Signal an den Signalweg 1 abgegeben. Das elektrische Signal ist für jeden elektronisch eingestellten Übertragungsparameter charakteristisch, also verschieden. Dadurch erhält der Benutzer dieses erfindungsgemäßen Hörgerätes über den Hörer 3 eine eindeutige Information über den jeweils gewählten und eingestellten Übertragungsparameter bzw. über das gewählte und eingestellte Signalbearbeitungsprogramm.In the hearing aid 6 designed according to the invention, the manual switching means 5 or the automatic switching means 5 'additionally acts on a signal output device which is designed as a tone frequency generator 7. The action can take place in such a way that when a transmission parameter is switched on, the tone frequency generator 7 e.g. is switched on briefly. During the activation of the audio frequency generator 7, at least one electrical signal is emitted from it to the signal path 1. The electrical signal is characteristic of each electronically set transmission parameter, i.e. different. As a result, the user of this hearing aid according to the invention receives, via the receiver 3, unambiguous information about the transmission parameter selected and set in each case or about the selected and set signal processing program.

Gemäß dem in Figur 1 dargestellten Ausführungsbeispiel ist nach der Erfindung eine Reset-Schaltung 8 vorgesehen, die ebenfalls auf das Mittel 4 zur elektronischen Einstellung eines Übertragungsparameter und auf den Tonfrequenzgenerator 7 einwirkt. Mit dieser Reset-Schaltung 8 kann sowohl das Mittel 4 als auch der Tongenerator 7 in eine Grundstellung (Ausgangsposition) zurückgeschaltet werden. Eine derartige Rückschaltung geschieht in vorteilhafter Weise insbesondere beim Betätigen eines Ein-/Ausschalters 9 des Hörgerätes 6. Es ist aber auch möglich, die Reset-Schaltung 8 bei Fehlwirkung des Schaltmittels 5 bzw. 5′ auslösen zu lassen. Dadurch kehrt das Hörgerät sowohl bei einer fehlerhaften Wirkung als auch beim Einschalten selbsttätig in eine Grundeinstellung des Übertragungsweges 1 zurück.According to the exemplary embodiment shown in FIG. 1, a reset circuit 8 is provided according to the invention, which also acts on the means 4 for the electronic setting of a transmission parameter and on the audio frequency generator 7. With this reset circuit 8, both the means 4 and the tone generator 7 can be switched back to a basic position (starting position). Such a downshift advantageously takes place in particular when an on / off switch 9 of the hearing aid 6 is actuated also possible to let the reset circuit 8 trip if the switching means 5 or 5 'malfunction. As a result, the hearing aid automatically returns to a basic setting of the transmission path 1 both in the event of a faulty effect and when it is switched on.

Erfindungsgemäß ist auch eine Zählschaltung 10 vorgesehen, die innerhalb der Wirkverbindung zwischen dem insbesondere manuell betätigbaren Schaltmittel 5 und dem Tonfrequenzgenerator 7 angeordnet ist. Von der Zählschaltung 10 werden die von dem Schaltmittel 5 abgegebenen Schaltsignale gezählt. Es wird sodann in Abhängigkeit von der Anzahl der von der Zählschaltung gezählten Schaltsignale (Zählerstand) der Tonfrequenzgenerator gesteuert. Dadurch ist es auf einfache Weise möglich, jedem von dem Schaltmittel 5 abgegebenen Schaltsignal ein charakteristisches Tonfrequenzsignal zuzuordnen.According to the invention, a counting circuit 10 is also provided, which is arranged within the operative connection between the switching means 5, which can be actuated in particular manually, and the audio frequency generator 7. The switching signals emitted by the switching means 5 are counted by the counter circuit 10. The audio frequency generator is then controlled as a function of the number of switching signals (counter reading) counted by the counter circuit. This makes it possible in a simple manner to assign a characteristic audio frequency signal to each switching signal output by the switching means 5.

Erfindungsgemäß kann in die Wirkverbindung zwischen dem manuell betätigbaren Schaltmittel 5 und dem Mittel 4 zur elektronischen Einstellung eines Übertragungsparameters sowie dem Tonfrequenzgenerator 7 eine Zeitschaltung 11 vorgesehen werden. Damit läßt sich die Wirkung des manuell betätigbaren Schaltmittels 5 auf das elektronische Einstellmittel 4 und auf den Tonfrequenzgenerator 7 zusätzlich zeitabhängig steuern. Des weiteren kann die Steuerung durch das manuell betätigbare Schaltmittel 5 derart erfolgen, daß eine Umschaltung auf einen neuen Übertragungsparameter (neues Programm) erst bei mehrmaliger, z.B. zweifacher, Betätigung des Schaltmittels 5 innerhalb einer bestimmten Zeitdauer erfolgt.According to the invention, a time circuit 11 can be provided in the operative connection between the manually operable switching means 5 and the means 4 for the electronic setting of a transmission parameter and the audio frequency generator 7. The effect of the manually operable switching means 5 on the electronic setting means 4 and on the audio frequency generator 7 can thus also be controlled as a function of time. Furthermore, the control can be carried out by the manually operable switching means 5 in such a way that a switch to a new transmission parameter (new program) takes place only after repeated, e.g. double, actuation of the switching means 5 takes place within a certain period of time.

Schließlich ist es auch noch möglich, die Signalabgabeeinrichtung 7 als Sprachfrequenzgenerator 12 auszubilden und/oder mit einem solchen Sprachgenerator zu koppeln. Dadurch kann eine unmittelbare Ansage des jeweils gewählten Übertragungsparameters und/oder Signalbearbeitungsprogrammes erfolgen.Finally, it is also possible to design the signal output device 7 as a speech frequency generator 12 and / or to couple it to such a speech generator. This means that the transmission parameter and / or signal processing program selected in each case can be announced immediately.

In Figur 2 ist ein hinter dem Ohr tragbares Hörgerät dargestellt, an dessen Bedienoberfläche der Ein-/Ausschalter 9 und das manuell betätigbare Schaltmittel 5 dargestellt sind. Das Schaltmittel 5 ist in diesem Ausführungsbeispiel als Taster ausgebildet.FIG. 2 shows a hearing device that can be worn behind the ear, on the user interface of which the on / off switch 9 and the manually operable switching means 5 are shown. The switching means 5 is designed in this embodiment as a button.

Die Darstellung in Figur 3 zeigt ein in dem Ohr tragbares Hörgerät (Concha-Gerät) mit Blick auf die von außen sichtbare Faceplate. Dieses erfindungsgemäße Hörgerät 6 enthält ebenfalls als Schaltmittel 5 einen Taster. Der Ein-/Ausschalter 9 ist bei diesem In-dem-Ohr-Hörgerät mit dem Lautstärkesteller kombiniert.The illustration in FIG. 3 shows a hearing aid (concha device) which can be worn in the ear with a view of the faceplate which is visible from the outside.
