Description
Die Erfindung bezieht sich auf die Verwendung eines Hörhilfegerätes als Hörsprechgarnitur eines Schwerhörigenschulungsgerätes, wobei das Hörgerät ein Gehäuse aufweist, in dem eine Schalleintrittsöffnung vorgesehen ist, durch die von außen auftreffende Schallsignale auf ein im Gehäuse befindliches Mikrofon weitergeleitet, mit Hilfe von ebenfalls im Gehäuse untergebrachten Verstärkern verstärkt und mittels eines Hörers über einen Schalleitungsschlauch und eine Ohrolive dem Gehör eines Trägers zugeführt werden, wobei an dem Gehäuse ein Anschluß mit Kontakten zur Verbindung mit einer Signalzuleitung zum Hörer (Audioeingang) angebracht ist.The invention relates to the use of a hearing aid device as a headset for a hearing impairment training device, the hearing aid having a housing in which a sound inlet opening is provided, through which sound signals impinging from outside are passed on to a microphone located in the housing, with the aid of amplifiers likewise accommodated in the housing amplified and fed to the hearing of a wearer by means of a handset via a sound line hose and an ear olive, a connection with contacts for connection to a signal line to the handset (audio input) being attached to the housing.
Geräte dieser Art sind z.B. in der US-A-41 37 431 oder DE-A-30 06 365 beschrieben. Die US-A-38 19 860 beschreibt außerdem ein Gegensprechgerät für Flugzeugpiloten. Dieses Gegensprechgerät unterdrückt Umgebungsgeräusche und dient zur Nachrichtenübertragung zwischen einem Flugzeug und einer Bodenstation. Der Schall, den der Pilot beim Sprechen erzeugt, wird über den Nasen-Rachenraum des Piloten zu einem im Ohr eingesetzten Mikrofon übertragen, dort in elektrische Signale umgewandelt und anschließend mittels drahtlosen Senders zur Bodenstation weitergeleitet. Dieses Gerät ist also kein Hörhilfegerät der eingangs genannten Art.Devices of this type are e.g. in US-A-41 37 431 or DE-A-30 06 365. US-A-38 19 860 also describes an intercom for aircraft pilots. This intercom suppresses ambient noise and is used to transmit messages between an aircraft and a ground station. The sound that the pilot generates while speaking is transmitted via the pilot's nasopharynx to a microphone inserted in the ear, where it is converted into electrical signals and then transmitted to the ground station using a wireless transmitter. So this device is not a hearing aid of the type mentioned.
In einer Broschüre der Firma Phonak AG, Fellbach-Schmiden, Schweiz, mit der Bezeichnung "Das standartisierte Phonak-Audio-Input-System" (Druck-Code-Nr. 28200/0283) sind Cros/Bicros/Stereocros-Schaltungsanordnungen von Hörgeräten stilisiert dargestellt. Bei derartigen Schaltungsanordnungen werden zwei Hörgeräte, die jeweils eigene Mikrofone besitzen, über Signalleitungen verbunden.In a brochure from Phonak AG, Fellbach-Schmiden, Switzerland, entitled "The standardized Phonak audio input system" (print code no. 28200/0283), cros / bicros / stereocros circuit arrangements for hearing aids are stylized shown. In such circuit arrangements, two hearing aids, each with their own microphones, are connected via signal lines.
In einer weiteren Broschüre der Fa. Phonak AG mit der Bezeichnung "Phonak Varionet C-D, Phonak Audio-Input-System" (Druck-Code-Nr. 28018.0682) ist auf Seite 8 eine Hörgeräteschaltung mit zwei Audio-Signalleitungen als Eingänge dargestellt, die parallel zum Mikrofon dem Hörgeräteverstärker zugeführt sind. Auf Seite 7 ist ein Modell A abgebildet, an dem neben dem 2-poligen Audio-Eingang-Anschluß ein 3-poliger Cros/Bicros-Anschluß vorgesehen ist.Another brochure from Phonak AG entitled "Phonak Varionet CD, Phonak Audio Input System" (print code no. 28018.0682) shows on page 8 a hearing aid circuit with two audio signal lines as inputs that run in parallel are supplied to the microphone of the hearing aid amplifier. A model A is shown on page 7, on which a 3-pin cross / bicros connection is provided in addition to the 2-pin audio input connector.
Aus der DE-C 967 080 sind ein Verfahren zur Einstellung der Grundcharakteristik von Hörhilfegeräten und Vorrichtungen zur Ausführung des Verfahrens bekannt. Zur Durchführung des bekannten Verfahrens ist eine Signalableitung von dem Hörgerätemikrofon über einen Vorverstärker zur Aufzeichnung auf einen Magnettonträger vorgesehen. Dazu weist das Hörgerät keine Tonsignalverbindung zwischen dem Mikrofon und der Endstufe auf. Ein über das Mikrofon des Hörgerätes aufgenommenes Tonsignal ist verfahrensgemäß nur mit zeitlichem Abstand mittels einer Tonaufzeichnungseinrichtung über die Endstufe des Hörgerätes wiedergebbar. Die Tonaufzeichnungseinrichtung weist zur Aufnahme und Wiedergabe zusätzliche Verstärker auf.DE-C 967 080 discloses a method for setting the basic characteristics of hearing aids and devices for carrying out the method. To carry out the known method, a signal derivation from the hearing aid microphone via a preamplifier is provided for recording on a magnetic sound carrier. For this purpose, the hearing aid has no sound signal connection between the microphone and the output stage. According to the method, a sound signal recorded via the microphone of the hearing aid can only be reproduced at intervals with a sound recording device via the output stage of the hearing aid. The sound recording device has additional amplifiers for recording and playback.
Bei Hörhilfegeräten werden die bekannten Anschlüsse für elektrische Signale insbesondere verwendet zur Einführung von Signalen aus einem externen Mikrofon, etwa einem solchen, das sich in einem Telefonhörer befindet oder welches Teil eines Gehörschulungsgerätes ist. Mit den Zuleitungen können auch Tonsignale aus anderen Signalerzeugern, wie Radio- und Fernsehempfängern, direkt in Hörhilfegeräte eingeleitet werden.In the case of hearing aids, the known connections for electrical signals are used in particular to introduce signals from an external microphone, for example one that is located in a telephone receiver or that is part of an auditory training device. With the feed lines, sound signals from other signal generators, such as radio and television receivers, can also be introduced directly into hearing aids.
Aus der DE-A-20 49 883 ist ein Schwerhörigen-Gehörschulungsgerät bekannt. Diese Anlage weist eine Induktionsschleife zur Übertragung der Signale an Schüler auf, die jedoch die üblichen Kopfhörer sowie Mikrofone verwenden.From DE-A-20 49 883 a hearing impaired hearing training device is known. This system has an induction loop for transmitting the signals to students, who, however, use the usual headphones and microphones.
Etwa beim Anschluß von Hörhilfegeräten an ein Gehörschulungsgerät ist es aber immer noch notwendig, ein gesondertes Mikrofon zur Aufnahme der Sprache der Schüler aufzustellen. Dies setzt aber für die Schülerplätze sogenannte Platzverstärker voraus. Dadurch wird aber ein Aufbau erhalten, der aufwendig ist und für jeden Schülerplatz vorgesehen werden muß.For example, when connecting hearing aids to a hearing training device, it is still necessary to set up a separate microphone to record the language of the pupils. However, this requires so-called space amplifiers for the student places. This way, however, a structure is obtained which is complex and must be provided for each student place.
Aufgabe der Erfindung ist es, die für jeden Schülerplatz vorgesehenen Platzverstärker dadurch zu vereinfachen, daß keine separate Hörsprechgarnitur an den Schülerplätzen notwendig ist.The object of the invention is to simplify the space amplifiers provided for each student seat in that no separate headset is required at the student seats.
Diese Aufgabe wird durch die Verwendung eines Hörhilfegerätes als Hörsprechgarnitur eines Schwerhörigenschulungsgerätes gemäß den Merkmalen des Patentanspruches gelöst.This object is achieved by using a hearing aid device as a headset for a hearing impairment training device in accordance with the features of the patent claim.
Der bisher in Hörschulungsgeräten, die auch Klassenverstärkeranlagen genannt werden, notwendige Platzverstärker kann bei Verwendung von Hörgeräten mit einem Anschluß zur Ableitung von Signalen vom Mikrofon (Audioausgang) wesentlich vereinfacht werden. Bis auf einen Mikrofonverstärker mit Schülersprechtaste können dabei alle übrigen, bisher notwendigen Teile weggelassen werden. Außer der Anpassung der unterschiedlichen Mikrofonpegel können alle anderen Funktionen der sonst üblichen Platzverstärker vom Hörgerät übernommen werden. Überdies ist keine Hörsprechgarnitur (Kombination von Hörer und Mikrofon) an den Schülerplätzen notwendig.The space amplifier previously required in hearing training devices, which are also called class amplifier systems, can be significantly simplified when using hearing devices with a connection for deriving signals from the microphone (audio output). Except for a microphone amplifier with student talk button, all other parts that were previously necessary can be omitted. In addition to adjusting the different microphone levels, all other functions of the usual place amplifiers can be taken over by the hearing aid. Furthermore, no headset (combination of handset and microphone) is required at the student seats.
Dabei wird nach der Erfindung beim Hörhilfegerät auch noch der Mikrofonverstärker durch den Hörgeräteverstärker ersetzt. Bei Übernahme der Schülersprechtaste zum Einschalten des jeweiligen Hörgerätemikrofons von der Schulanlage in die Anschlußleitung zum Hörgerät verbleibt dann von der bekannten Ausstattung der Schülerplätze nur noch die eigentliche Anschlußkupplung. Somit ist nach der Erfindung eine wesentliche Reduzierung des bisherigen Aufwandes möglich.According to the invention, the microphone amplifier is also replaced by the hearing aid amplifier in the hearing aid device. When the student's speaking button is taken over to switch on the respective hearing aid microphone from the school system into the connecting line to the hearing aid, only the actual connection coupling remains of the known equipment of the student places. Thus, according to the invention, a substantial reduction in the previous effort is possible.
Weitere Einzelheiten und Vorteile der Erfindung werden nachfolgend anhand der in den Figuren dargestellten Ausführungsbeispiele erläutert.Further details and advantages of the invention are explained below using the exemplary embodiments illustrated in the figures.

In der Figur 1 ist mit 1 ein Hörhilfegerät bezeichnet, desse Gehäuse 2 die Einzelteile des elektrischen Aufbaus enthält und mittels eines Hakens 3 über den oberen Ansatz eines Ohres 4 getragen wird. Dieses Gerät funktioniert in üblicher Weise, indem Schall, welcher durch eine Öffnung 5 eintritt, über eine Schaltung, wie sie in Figur 4 gezeichnet ist, verstärkt und über einen Schalleitungsschlauch 6, der mittels einer Ohrolive im Ohrkanal verankert ist, dem Gehör des Trägers zugeführt wird.In FIG. 1, 1 denotes a hearing aid, the housing 2 of which contains the individual parts of the electrical structure and is worn over the upper attachment of an ear 4 by means of a hook 3. This device works in the usual way by amplifying sound that enters through an
Außer über die Öffnung 5 können wiederzugebende Signale dem Gerät 1 auch über einen Anschluß 10 zugeführt werden. Diese Signale werden etwa in einem Mikrofon 47 (Figur 5) aufgenommen, das Teil einer Gehörschulungsanlage ist. Die Zuführung erfolgt über eine Leitung 11. Für den eigentlichen Anschluß weist das Gerät 1 ein Verbindungsstück 12 (Figur 3) auf, an welchem sich Kontakte 13, 14 und 15 befinden. An die Kontakte 13 bis 15 sowie 13.1 und 14.1 schließen sich im Inneren des Gerätes 1 Leitungen 16, 17 und 18 sowie 16.2 und 17.2 an, welche die eigentlichen Verbindungen mit den entsprechenden Teilen 20 bis 24 der Schaltung des Hörgerätes 1 darstellen. Der Kontakt 15 stellt dabei eine gemeinsame Leitung für Signale dar, die zum Hörer 20 gelangen sollen und die vom Mikrofon 21 abgeleitet werden sollen. Die eigentlichen Signalleitungen stellen für die Signalzuleitung, d.h. den Audioeingang, die Leitung 17 und für die Schallsignalableitung, d.h. den Audioausgang, die Leitung 16 dar.In addition to the
Das ein Mikrofon 21, einen Verstärker 22 mit einem Vorverstärkerteil 22.1, einem Lautstärkeregler 23 sowie einem Endverstärkerteil 23.1 und einen Hörer 20 umfassende Hörhilfegerät 1 ist an sich von üblicher Bauart, wobei die Energie aus einer Stromquelle 24, etwa einer Kleinbatterie, geliefert wird. Ein im Mikrofon 21 aufgenommenes Signal kann zwischen den Kontakten 13 und 15 oder 13.1 und 15 je nach Beschaltung vom Hörgerät 1 abgenommen werden. Die Abnahme hinter dem Vorverstärker 22.1 ist vorteilhaft, um auftretendes Übersprechen zu verhindern oder die Ausgangsleistung an unterschiedliche Kabelkapazitäten der Anlage anzupassen. Der Verstärker 22 arbeitet als linearer Verstärker ohne Frequenzbeeinflussung und im allgemeinen ohne Beeinflussung der Dynamik.The
Ebenso wie die Abnahme des Signals zwischen den Kontakten 13 und 15 vom ganzen Verstärker bzw. 13.1 und 15 von einem Teil davon erfolgen kann, ist es auch möglich, die Zuführung des Signals über den ganzen Verstärker 22 durch Anschluß zwischen 14 und 15 zu leiten bzw. durch Anschluß zwischen 14.1 und 15 nur über den Lautstärkeregler 23 und den Endverstärker 22.2. Auch hier kann durch die Wahl des Anschlusses eine Anpassung an die vorliegenden Gegebenheiten erfolgen.Just as the signal between
In der Figur 5 ist mit 30 die Lehrerstation einer Gehörschulungsanlage bezeichnet. In der schematischen Darstellung sind Schülerstationen 31 bis 34 angeschlossen. An den Schülerstationen 31 bis 33 liegen Hörhilfegeräte 35 bis 37, die erfindungsgemäß ausgestaltet sind. Der Schülerplatz 34 ist unbesetzt. Die Schülerplätze 31 bis 34 enthalten jeweils einen Platzverstärker 38 bis 41 sowie einen Druckknopfschalter, der als Sprechtaste 42 bis 45 dient. Eine entsprechende Taste 46 ist auch zwischen dem Lehrermikrofon 47 und dem Lehrerplatzverstärker 48 untergebracht. Während die Leitung 50 zu den Schülerplätzen 31 bis 34 fest verlegt ist, stellen die Verbindungsleitungen 11 zwischen den Schülerplätzen 31 bis 34 und den jeweiligen Hörhilfegeräten 1 abnehmbare Ansteckleitungen dar. So können die Verbindungsleitungen 16 bis 18 eines jeden Hörgerätes 1 über die drei Adern 16.1, 17.1 und 18.1 der Leitung 11 über den Anschluß 10 mit den Schülerplätzen 31 bis 34 und dem Lehrerplatz 30 verbunden werden.In FIG. 5, 30 denotes the teacher station of an ear training system. In the schematic representation,
Die Funktion des Schulungsgerätes weicht nicht von derjenigen üblicher Schulungsgeräte ab. Der Hauptunterschied besteht darin, daß anstatt der in der Regel verwendeten Hörer und Mikrofon umfassenden Hörsprechgarnituren erfindungsgemäß ausgestaltete Hörgeräte 1 benutzt werden. Dadurch kann einerseits das Hören durch die individuelle Anpassung der Geräte 1 optimal gestaltet werden und andererseits brauchen keine zusätzlichen Mikrofone aufgestellt zu werden, weil die Mikrofone 21 der Schüler und das Lehrermikrofon 47 für die Benutzung der Anlage ausreichen. Will einer der Teilnehmer einen Beitrag in die Anlage sprechen, so drückt er seine Sprechtaste und schließt einen der Schalter 42 bis 46. Dann wird das jeweilige Mikrofon 21 bzw. 47 über entsprechende Verstärker 22 bzw. 38 bis 41 oder 48 wirksam, so daß ein Signal über die Leitung 18.1 zum jeweiligen Hörer 20 eines Schülerhörgerätes 1 kommt.The function of the training device does not differ from that of conventional training devices. The main difference is that instead of the headphones and microphone sets which are generally used,
