Description

Die vorliegende Erfindung betrifft ein Hörgerät gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a hearing aid according to the preamble of claim 1.

Ein herkömmliches Hörgerät enthält bekanntlich ein Mikrofon, das den Umgebungsschall direkt aufnimmt und ein entsprechendes elektrisches Tonsignal erzeugt. Dieses elektrische Tonsignal wird nach geeigneter Verstärkung, wobei der jeweilige Benutzer des Hörgeräts den Verstärkungsfaktor und damit die Lautstärke einstellen kann, über einen Lautsprecher ausgegeben.As is known, a conventional hearing aid contains a microphone, that directly picks up the ambient sound and turns it on corresponding electrical sound signal generated. This electrical Sound signal is given after suitable amplification, whereby the respective user of the hearing aid has the amplification factor and so that you can adjust the volume, through a speaker spent.

Es sind auch Hörgeräte bekannt, die neben einem Mikrofon zur direkten Schallaufnahme noch mindestens einen weiteren Signalaufnehmer aufweisen, der nach einem anderen Aufnahmeprinzip arbeitet und ebenfalls ein Tonsignal erzeugt, das über den Lautsprecher ausgegeben werden kann. Bei derartigen Signalaufnehmern handelt es sich beispielsweise um induktive Aufnehmer, die in der Lage sind, die von einem Telefon, von Ringleitungen oder von Computern mit induktiven Schleifen ausgegebenen elektromagnetischen Signale über eine induktive Kopplung aufzunehmen und in ein entsprechendes elektrisches Ausgangssignal umzuwandeln. Durch Verwendung eines derartigen induktiven Signalaufnehmers ist es somit möglich, die von den genannten Geräten ausgegebenen Tonsignale direkt, d.h. ohne den Umweg über den Telefonlautsprecher bzw. den Computer-Lautsprecher aufzunehmen, so daß unter Umständen eine wesentlich bessere Signalqualität erzielbar ist. Beispielsweise ist es auch möglich, in einem Konzertsaal oder dergleichen eine induktive Schallquelle vorzusehen, die das aufgenommene Konzert induktiv in den Saal überträgt, so daß der Träger des Hörgeräts einen deutlich besseren Hörgenuß haben kann als mit dem eingebauten Hörgeräte-Mikrofon. Bei Räumen mit schlechter Akustik oder im Rahmen von Vortragsveranstaltungen könnten derartige induktive Übertragungssysteme sogar von solchen Leuten verwendet werden, die an sich keine Hörprobleme haben.Hearing aids are also known, in addition to a microphone for direct sound recording at least one more Have signal pickups that after another Recording principle works and also generates a sound signal, that can be output through the speaker. Such signal pickups are, for example to inductive transducers that are capable of a telephone, ring lines or computers with inductive Loops output electromagnetic signals record via an inductive coupling and in a corresponding convert electrical output signal. By Use of such an inductive signal pickup is it is thus possible to output from the devices mentioned Sound signals directly, i.e. without going through the phone speaker or record the computer speaker, so that under certain circumstances a much better signal quality is achievable. For example, it is also possible to a concert hall or the like an inductive sound source to provide the recorded concert inductively in transmits the hall so that the wearer of the hearing aid can have much better listening pleasure than with the built-in Hearing aid microphone. In rooms with poor acoustics or in the context of lectures such inductive transmission systems even from such people be used that have no hearing problems per se.

Neben derartigen induktiven Signalaufnehmern werden in manchen Hörgeräten mittlerweile auch Infrarot-, Ultraschall- oder Funk-Signalaufnehmer verwendet, so daß die Hörgeräteträger auch derartige modulierte Schallquellen wahrnehmen können.In addition to such inductive signal pickups some hearing aids now also infrared, ultrasound or radio signal pickup used so that the Hearing aid wearers also use such modulated sound sources can perceive.

Bei Hörgeräten dieser Art, die neben dem Mikrofon mindestens einen weiteren, nach einem der genannten alternativen Aufnahmeprinzipien arbeitenden Signalaufnehmer aufweisen, ist ein Wählschalter vorgesehen, mit dem der Träger des Hörgeräts festlegen kann, welches der jeweiligen Tonsignale, also das Tonsignal des Mikrofons oder das eines anderen Signalaufnehmers, zu Gehör gebracht werden soll. Ein wesentlicher Nachteil dieser Art der Signalumschaltung liegt darin, daß der Träger des Hörgeräts in der überwiegenden Mehrzahl der Fälle das Mikrofon zur direkten Schallaufnahme verwenden wird, da die induktiven Schallquellen und dergleichen naturgemäß wesentlich seltener zur Verfügung stehen. Es besteht somit die Gefahr, daß der Träger des Hörgeräts aus Gründen der Bequemlichkeit darauf verzichtet, bei Vorhandensein einer induktiven Schallquelle auf den entsprechenden Signalaufnehmer umzuschalten. Die Träger eines solchen Hörgeräts werden in vielen Fällen ganz einfach auch vergessen, daß ihr Hörgerät die Möglichkeit einer derartigen alternativen Signalaufnahme bietet. Hierdurch werden die Möglichkeiten eines derartigen Kombinations-Hörgeräts nur unvollständig genutzt bzw. der Träger des Hörgeräts kommt häufig nicht in den Genuß der besseren Signalqualität des induktiven Signalaufnehmers oder dergleichen.In hearing aids of this type, which at least in addition to the microphone another, according to one of the alternatives mentioned Have recording principles working recording principles, a selector switch is provided with which the carrier of the hearing aid can determine which of the respective sound signals, so the sound signal from the microphone or that of another Signal pickup to be heard. On major disadvantage of this type of signal switching lies in the fact that the wearer of the hearing aid is predominant Most of the cases the microphone for direct sound recording will use as the inductive sound sources and the like naturally much less often available stand. There is therefore a risk that the carrier of the hearing aid for the sake of convenience, in the presence of an inductive sound source to switch to the corresponding signal sensor. The In many cases, such hearing aids become worn just forget that your hearing aid has the option offers such an alternative signal recording. Hereby the possibilities of such a combination hearing aid only incompletely used or the carrier of the Hearing aids often do not enjoy better signal quality of the inductive signal pickup or the like.

Ein Hörgerät, das neben dem Mikrofon mindestens einen weiteren, nach einem der genannten alternativen Aufnahmeprinzipien arbeitenden Signalaufnehmer aufweist, ist aus der DE-A-25 10 731 bekannt. Es sind ein Schallempfangswandler (Mikrofon) und ein Induktionsempfangswandler vorgesehen, deren Signale über eine automatisch gesteuerte Torschaltung einem Verstärker zugeleitet werden, derart, daß die von dem Induktionsempfangswandler gewandelten Signale in einer einen Umschalter steuernden Steuerschaltung bewertet und im Falle der Empfangswürdigkeit dem Verstärker über die Torschaltung zugeführt werden, wobei die von dem Schallempfangswandler aufgenommenen Signale zusätzlich wahlweise mit unverminderten oder verminderten Pegel über die Torschaltung geführt und bei Ausfall induktiv übertragener Information mit unvermindertem Pegel dem Verstärker aufgeschaltet werden. Die Signale des Schallempfangswandlers werden wahlweise über einen von Hand zwischen drei Schaltstellungen bewegbaren Umschalter entweder in der ersten Stellung des Umschalters mit unvermindertem Pegel und in der zweiten Stellung mit vermindertem Pegel ebenfalls dem Verstärker zugeführt. In einer dritten Schaltstellung des Schalters wird die alleinige Übertragung der von dem Induktionsempfangswandler aufgenommenen Signale ermöglicht. Dem Hörbehinderten ist damit die Möglichkeit eingeräumt, nach freier Wahl bei Empfang aus einer Induktionsschleife über den Schallempfangswandler zusätzliche akustische Informationen, z.B. auch Umweltgeräusche, unverändert oder abgeschwächt aufzunehmen oder diese völlig auszublenden.A hearing aid that has at least one in addition to the microphone further, according to one of the alternative recording principles mentioned working signal pickup is off DE-A-25 10 731 known. It is a sound transducer (Microphone) and an induction reception converter are provided, whose signals via an automatically controlled gate circuit be fed to an amplifier such that the signals converted by the induction reception converter evaluated in a control circuit controlling a changeover switch and in the case of reception worthy of the amplifier the gate circuit are supplied, which of the Signals received transducer additionally recorded signals optionally with undiminished or reduced level above the gate circuit guided and in the event of failure inductively transmitted Information with undiminished level to the amplifier be activated. The signals of the sound receiving transducer are either hand-held between three Switch positions movable switch either in the first Position of the switch with undiminished level and also in the second position with reduced level fed to the amplifier. In a third switch position of the switch is the sole transmission of that from the Induction receiving converter allows recorded signals. This gives the hearing impaired the opportunity to of your choice when receiving from an induction loop additional acoustic information via the sound receiving transducer, e.g. also environmental noises, unchanged or weakened or completely hide them.

Nachteilig bei dem Hörgerät nach der DE-A-25 10 731 ist, daß die von dem Schallempfangswandler kommenden Signale und die von dem Induktionsempfangswandler kommenden Signale zwar über die Torschaltung geführt werden, der Umschaltvorgang zwischen den eingehenden Signalen zur Weiterführung eines dieser Signale an den Verstärker jedoch nur anhand der Empfangswürdigkeit des vom Induktionsempfangswandler kommenden Signales erfolgt: erkennt die Steuerschaltung ein ausreichend starkes Signal von dem Induktionsempfangswandler, wird dieses Signal in der Torschaltung auf den Verstärker gelegt und das bisher dort anliegende Signal vom Schallempfangswandler wird um die Torschaltung herum über den Umschalter mit den drei Schaltstellungen (ungehinderter Signaldurchlaß - Signaldurchlaß mit Dämpfung - kein Signaldurchlaß) auf den Verstärkereingang gelegt. In den Schalterstellungen "ungehinderter Signaldurchlaß" und "Signaldurchlaß mit Dämpfung" erfolgt somit stets eine Mischung der beiden von den Empfangswandlern kommenden Signale, wenn die Torschaltung das Signal vom Induktionsempfangswandler auf den Verstärkereingang durchschaltet. Mit anderen Worten, die Lautstärke des Signalausganges am Verstärker wird ständig schwanken, wenn die Torschaltung zwischen den beiden Zuständen "Signal vom Schallempfangswandler" oder "Signal vom Induktionsempfangswandler" umschaltet, da in dem ersten abhängig Schaltzustand das Signal vom Schallempfangswandler alleine den Verstärker erreicht und im zweiten Schaltzustand das Signal vom Induktionsempfangswandler plus eventuellen Signalen vom Schallempfangswandler. Vermeiden läßt sich dies nur, wenn der Benutzer den Umschalter in die dritte Stellung ("kein Signaldurchlaß") bringt. Dies ist störend und umständlich, bei IdO-Geräten oftmals gar nicht möglich.A disadvantage of the hearing aid according to DE-A-25 10 731 is that the signals coming from the sound receiving transducer and the signals coming from the induction receive converter the switching process between the incoming signals for continuation however, only one of these signals to the amplifier based on the reception worthiness of the induction reception converter coming signals: recognizes the control circuit a sufficiently strong signal from the induction reception converter, this signal is in the gate circuit placed on the amplifier and what was previously there Signal from sound transducer is around the gate circuit around with the switch with the three switch positions (unimpeded signal transmission - signal transmission with damping - no signal passage) placed on the amplifier input. In the switch positions "unimpeded signal passage" and "Signal transmission with damping" is therefore always mixed of the two signals coming from the receive transducers, when the gate circuit receives the signal from the induction receiving transducer switched through to the amplifier input. With in other words, the volume of the signal output on the amplifier will fluctuate constantly if the gate circuit between the two states "signal from sound transducer" or "signal from the induction receiver converter", since in the first dependent switching state the signal from Sound receiving transducer alone reaches the amplifier and in the second switching state the signal from the induction receiver converter plus any signals from the sound transducer. This can only be avoided if the user uses the Switch to the third position ("no signal passage") brings. This is annoying and cumbersome for ITE devices often not possible at all.

Es ist Aufgabe der vorliegenden Erfindung, ein Hörgerät mit gegenüber bekannten Hörgeräten verbessertem Nutzungskomfort zu schaffen.The object of the present invention is a hearing aid with improved user comfort compared to known hearing aids to accomplish.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.This problem is solved by the features of claim 1.

Die Erfindung schlägt demnach vor, die Überwachungseinrichtung die Tonsignale des Mikrofons und aller Signalaufnehmer überwachen zu lassen, diese Tonsignale auf ihre jeweilige Signalqualität zu überprüfen und mittels der Schalteinrichtung zumindest dasjenige Tonsignal zur Verstärkung auszuwählen, das momentan die beste Signalqualität aufweist. The invention accordingly proposes the monitoring device the sound signals from the microphone and all signal pickups to have these sound signals monitored for their respective Check signal quality and by means of Switching device at least that sound signal for amplification to select the one that currently has the best signal quality having.

Mit der Erfindung wird somit erreicht, daß das Hörgerät gleichsam automatisch auf denjenigen Signalaufnehmer umschaltet, der in Abhängigkeit von der jeweiligen Tonquelle die beste Signalqualität liefert. Wenn der Träger des Hörgeräts beispielsweise zu telefonieren beginnt, erfaßt die erfindungsgemäße Überwachungseinrichtung anhand des Ausgangssignals des induktiven Signalaufnehmers, daß die Signalqualität der induktiv emittierenden Tonquelle in Form des Telefongeräts besser als die mit dem Mikrofon erzielbare Signalqualität ist und verstärkt anstelle des Mikrofon-Ausgangssignals das Ausgangssignal des induktiven Signalaufnehmers. Der Träger des Hörgeräts muß daher nicht von Hand auf die jeweils gewünschte Signalquelle umschalten, was einerseits zu einer wesentlich bequemeren Bedienung des Hörgeräts führt und andererseits den Vorteil bietet, daß die Möglichkeiten des Hörgeräts wesentlich besser ausgenutzt werden bzw. stets ein optimaler Hörgenuß erzielbar ist.With the invention it is thus achieved that the hearing aid automatically switches over to the signal pickup, depending on the respective sound source provides the best signal quality. If the wearer of the hearing aid for example, begins to make calls, records the Monitoring device according to the invention based on the output signal of the inductive signal pickup that the signal quality the inductively emitting sound source in the form of the telephone device better than that which can be achieved with the microphone Signal quality is and amplifies instead of the microphone output signal the output signal of the inductive transducer. The wearer of the hearing aid therefore does not have to switch manually to the desired signal source, which on the one hand makes it much more convenient to use of the hearing aid and on the other hand offers the advantage that the possibilities of the hearing aid are much better are exploited or always an optimal listening pleasure can be achieved is.

Gemäß einer Weiterbildung der Erfindung erzeugt die Überwachungseinrichtung mittels der Schalteinrichtung ein solches Tonsignal, das einem Signalgemisch aus mehreren Tonsignalen etwa gleich guter Signalqualität entspricht. Somit ist es beispielsweise möglich, den mit dem Mikrofon aufgenommenen Direktschall eines Telefons mit dem Tonsignal des induktiven Signalaufnehmers zu mischen und damit die Gesamt-Signalqualität gegebenenfalls zu verbessern.According to a development of the invention, the Monitoring device by means of the switching device such sound signal that a signal mixture of several Sound signals corresponds approximately to the same good signal quality. It is thus possible, for example, to use the microphone recorded direct sound of a telephone with the sound signal to mix the inductive signal pickup and thus the Improve overall signal quality if necessary.

Die erfindungsgemäße Überwachungseinrichtung ermittelt die Signalqualität der jeweiligen Tonsignals beispielsweise durch Vergleich mit einem für das betreffende Tonsignal spezifischen Referenzwert. Jedoch ist es auch möglich, einen Signalprozessor oder dergleichen vorzusehen, der das betreffende Tonsignal mit einer bestimmten Hüllkurve vergleicht oder durch Spektralanalyse ermittelt, ob das Signal eine ausreichende Qualität aufweist. The monitoring device according to the invention is determined the signal quality of the respective audio signal, for example by comparison with one for the sound signal in question specific reference value. However, it is also possible to get one To provide signal processor or the like, the compares the sound signal in question with a specific envelope or determined by spectral analysis whether the signal is of sufficient quality.

Weiterhin besteht (mit Ausnahme des von natürlichen Schallquellen stammenden Tonsignals des Mikrofons) die Möglichkeit, in die künstlich erzeugten induktiven, infraroten, Funksignale usw. eine Kennung einzufügen, die von der Überwachungseinrichtung mit geringem technischen Aufwand erfaßt werden kann und die angibt, daß das betreffende Signal eine geeignete Signalqualität aufweist.Furthermore (with the exception of natural Sound source of the microphone), the possibility of into the artificially created inductive, infrared, Radio signals etc. to insert an identifier issued by the Monitoring device with little technical effort can be detected and indicates that the signal in question has a suitable signal quality.

Die Umschaltung von einem Tonsignal auf ein anderes bzw. die Änderung des Mischungsverhältnisses mehrerer Tonsignale wird erfindungsgemäß vorzugsweise mit einer vorbestimmten Hysterese bzw. Verzögerungszeit durchgeführt, um zu verhindern, daß sich die Klangfarbe des vom Lautsprecher ausgegebenen Tons zu häufig ändert, womit Irritationen des Trägers des Hörgeräts verringert bzw. vollständig vermieden werden können. Die Art bzw. Dauer der Hysterese kann gegebenenfalls vom Benutzer des Hörgeräts nach Belieben eingestellt bzw. geändert werden.Switching from one sound signal to another or changing the mixing ratio of several sound signals is preferably according to the invention with a predetermined Hysteresis or delay time carried out in order to prevent the timbre of the from the speaker output sound changes too often, causing irritation of the Wearer of the hearing aid reduced or avoided completely can be. The type or duration of the hysteresis can, if necessary set by the user of the hearing aid at will or be changed.

Das Mikrofon des Hörgeräts und der bzw. die nach dem anderen Aufnahmeprinzip arbeitende(n) Signalaufnehmer liefern in der Regel Tonsignale mit unterschiedlichem Ausgangspegel. Die Erfindung sieht daher in einer weiteren Ausführungsform eine Pegelanpassungseinrichtung vor, die für die Tonsignale des Mikrofons und aller anderen Signalaufnehmer eine jeweils separate Pegelanpassung erlaubt, wobei die Überwachungseinrichtung die Pegelanpassungseinrichtung derart ansteuert, daß beim Umschalten von einem Tonsignal auf ein anderes bzw. beim Mischen mehrerer Tonsignale im wesentlichen die gleiche Ausgangslautstärke erzielt werden kann. Hierdurch werden Irritationen des Trägers des Hörgeräts beim Umschalten bzw. beim Ändern des Mischungsverhältnisses weitgehend vermieden.The microphone of the hearing aid and the one after supply other pick-up principle working signal transducer usually sound signals with different output levels. The invention therefore sees another Embodiment a level adjuster before for the sound signals of the microphone and all other signal recorders each allows a separate level adjustment, whereby the monitoring device the level adjustment device so controlled that when switching from a sound signal to another or when mixing several sound signals essentially the same output volume can be achieved can. This will irritate the wearer of the Hearing aid when switching or changing the mixing ratio largely avoided.

Ein weiterer Aspekt der Erfindung liegt darin, daß bei Verwendung eines Signalaufnehmers, der nach dem induktiven Aufnahmeprinzip arbeitet, das Hörgerät auch als Freisprecheinrichtung für z.B. ein Telefon verwendet werden kann. Eine solche Art der Freisprecheinrichtung funktioniert sogar dann, wenn der Lautsprecher des Telefons beim Freisprechen vollständig zurückgeregelt wird, so daß nur der Träger des Hörgeräts in der Lage ist, den Teilnehmer am anderen Ende der Telefonleitung zu hören. Für den Fall, daß das Telefon das eingehende Gespräch nicht induktiv, sondern mittels Infrarot, Ultraschall oder über ein anderes geeignetes Übertragungsmittel überträgt, funktioniert das Freisprechen auch über einen auf das jeweilige Übertragungsmittel hin ausgelegten Signalaufnehmer im Hörgerät.Another aspect of the invention is that Use of a signal pick-up according to the inductive Recording principle works, the hearing aid also as a hands-free device for e.g. a phone can be used. A such a type of speakerphone even works then when the speaker of the phone is handsfree is completely reduced so that only the wearer of the Hearing aid is able to put the participant on the other end heard on the phone line. In the event that the phone the incoming call is not inductive, but by means of infrared, Ultrasound or other suitable means of transmission handsfree works also via one to the respective transmission medium designed signal pickups in the hearing aid.

Ein derartiges "Hörgerät" ist nicht nur für Personen mit Hörschaden geeignet, sondern auf für Personen ohne Hörschaden als Freisprecheinrichtung z. B. in Kraftfahrzeugen oder im Büro für "Vieltelefonierer". Eine besonders bevorzugte Anwendung eines derartigen erfindungsgemäßen "Hörgeräts" besteht in der Bereitstellung eines zusätzlichen Kommunikationskanals für Computer- bzw. PC-Nutzer. Viele PCs sind heute mit einer sogenannten Soundkarte ausgerüstet, mittels der sich auch Sprache erzeugen läßt. Werden diese Tonsignale induktiv, mittels IR oder Ultraschall, etc. durch den PC ausgegeben, wird ein akustischer Kommunikationskanal mit dem Computer bereitgestellt, der keine andere Person in unmittelbarer Umgebung stört. Die Reaktion des Computernutzers kann über die Tastatur erfolgen, so daß ebenfalls keine Störung anderer Personen erfolgt. Ein derartiges erfindungsgemäßes Hörgerät ist auch für Computer- und Videospiele geeignet, die mit der von ihnen erzeugten Geräuschkulisse häufig sehr störend sind.Such a "hearing aid" is not just for people suitable with hearing loss, but for people without hearing loss as a speakerphone z. B. in motor vehicles or in the office for "frequent callers". A particularly preferred one Use of such an inventive "Hearing Aid" consists in providing an additional one Communication channel for computer or PC users. Many PCs today are equipped with a so-called sound card, by means of which language can also be generated. Become these sound signals inductively, by means of IR or ultrasound, etc. issued by the PC, an acoustic communication channel provided with the computer that no other Disturbing person in the immediate vicinity. The reaction the computer user can be done via the keyboard, so that there is also no interference with other people. Such a thing Hearing aid according to the invention is also for computer and video games that work with the ones they produce Background noise is often very distracting.

Damit wird für ein "Hörgerät" gemäß der vorliegenden Erfindung ein völlig neuer Markt erschlossen. Wichtig hierbei ist auch, daß die Freisprechfunktion auch dann gegeben ist, wenn nur ein einziger Signalaufnehmer, z. B. ein induktiver Aufnehmer, vorhanden ist. Dies wäre dann der Fall eines atypischen Hörgeräts ohne Mikrofon. This is for a "hearing aid" according to the present Invention opened up a completely new market. Important here is also that the hands-free function is also given is when only a single signal pickup, e.g. B. an inductive Transducer, is present. That would be the case an atypical hearing aid without a microphone.

Die Erfindung wird nachstehend anhand der Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung näher erläutert.The invention is described below based on the description of exemplary embodiments with reference to the drawing explained in more detail.

Es zeigt:

  • Fig. 1 ein erstes Ausführungsbeispiel eines erfindungsgemäßen Hörgerätes; und
  • Fig. 2 ein zweites Ausführungsbeispiel, bei dem eine Pegelanpassungseinrichtung vorgesehen ist.
    • It shows:
  • Figure 1 shows a first embodiment of a hearing aid according to the invention. and
  • Fig. 2 shows a second embodiment in which a level adjustment device is provided.

    • Gemäß Fig. 1 weist das erfindungsgemäße Hörgerät als Tonsignal-Quellen ein Mikrofon 10 zur direkten Schallaufnahme sowie zwei weitere Signalaufnehmer 11 und 12 auf. Das Mikrofon 10 ist beispielsweise ein elektrostatisches Mikrofon und erzeugt in bekannter Weise ein elektrisches Tonsignal. Bei dem ersten Signalaufnehmer 11 handelt es sich beispielsweise um einen induktiven Aufnehmer, der in der Lage ist, elektromagnetische Wellen induktiv aufzunehmen und ein entsprechendes Tonsignal zu erzeugen. Der Signalaufnehmer 11 kann somit zur Aufnahme der von z.B. einem Telefon ausgegebenen elektromagnetischen Signale verwendet werden. Der zweite Signalaufnehmer 12 ist beispielsweise ein Infrarot-Aufnehmer, der geeignet modulierte infrarote Signale empfängt und in ein Tonsignal umsetzt.1, the hearing aid according to the invention has Sound signal sources a microphone 10 for direct sound recording as well as two further signal pickups 11 and 12. The Microphone 10 is, for example, an electrostatic microphone and generates an electrical sound signal in a known manner. The first signal pickup 11 is concerned for example, an inductive transducer that is in the Is able to pick up electromagnetic waves inductively and generate a corresponding sound signal. The signal pickup 11 can thus be used to accommodate e.g. a phone output electromagnetic signals used become. The second signal pickup 12 is, for example an infrared sensor that is suitably modulated infrared Receives signals and converts them into a sound signal.

    Das jeweilige Tonsignal des Mikrofons 10 sowie der beiden Signalaufnehmer 11 und 12 liegt an einem jeweils zugeordneten Eingangsanschluß einer Schalteinrichtung 20 an. Die Schalteinrichtung 20 ist in der Lage, eines der anliegenden Tonsignale auszuwählen und ein entsprechendes Ausgangssignal zu erzeugen, das einem Verstärker 30 zugeführt wird. Der Verstärker 30 hat einen bekannten Aufbau, so daß weitere Erläuterungen hierzu überflüssig sind. The respective sound signal of the microphone 10 and the two Signal pickups 11 and 12 are connected to a respective one Input connection of a switching device 20. The switching device 20 is capable of one of the adjacent ones Select audio signals and a corresponding output signal to generate that fed to an amplifier 30 becomes. The amplifier 30 has a known structure, so that further explanations are unnecessary.

    Die Schalteinrichtung 20 ist weiterhin in der Lage, aus mindestes zwei der zugeführten Tonsignale ein Signalgemisch zu erzeugen, das dann dem Verstärker 30 zugeführt wird. Das Ausgangssignal des Verstärkers 30 liegt an einem Lautsprecher 64 an, so daß der Träger des Hörgeräts in der Lage ist, das jeweils verstärkte Tonsignal bzw. Tonsignalgemisch zu hören.The switching device 20 is still able to at least two of the supplied audio signals are mixed signals to generate, which is then fed to the amplifier 30. The The output signal of the amplifier 30 is at a loudspeaker 64 so that the wearer of the hearing aid is able to is the respective amplified sound signal or sound signal mixture to listen.

    Erfindungsgemäß ist weiterhin eine Überwachungseinrichtung 25 vorgesehen, an der ebenfalls das jeweilige Tonsignal des Mikrofons 10 sowie der beiden Signalaufnehmer 11 und 12 anliegt. Die Überwachungseinrichtung 25 überwacht diese Tonsignale auf ihre jeweilige Signalqualität und wählt über die Schalteinrichtung 20 zumindest dasjenige Tonsignal zur weiteren Verstärkung aus, das momentan die beste Signalqualität aufweist. Wenn zwei oder alle drei dieser Signalquellen eine etwa gleich gute Signalqualität aufweisen, veranlaßt die Überwachungseinrichtung 25 die Schalteinrichtung 20 zur Erzeugung eines geeignet gemischten Tonsignals.A monitoring device is also in accordance with the invention 25 provided on which also the respective sound signal the microphone 10 and the two signal pickups 11 and 12 is present. The monitoring device 25 monitors these sound signals to their respective signal quality and selects at least one via the switching device 20 Sound signal for further amplification, which is currently the best signal quality. If two or all three these signal sources have an approximately equally good signal quality have, the monitoring device 25 causes the Switching device 20 for generating a suitably mixed Tone signal.

    Um die Signalqualität jedes Tonsignals zu ermitteln, vergleicht die Überwachungseinrichtung 25 jedes Tonsignal z.B. mit einem für das betreffende Tonsignal spezifischen Referenzwert, wobei nur bei Überschreiten des betreffenden Referenzwerts eine ausreichende Signalqualität angenommen wird. Die Signalqualität kann jedoch auch mittels eines Signalprozessors durch Spektralanalyse oder dergleichen ermittelt werden. Wenn das betreffende Signal eine Kennung enthält, die nur bei genügender Qualität gesendet wird, kann die Überwachungseinrichtung 25 eine Schaltung enthalten, die auf eine solche (ggf. kontinuierlich enthaltene oder nur am Beginn der Übertragung gesendete) Kennung anspricht und das betreffende Signal gleichsam "freigibt".To determine the signal quality of each audio signal, the monitor 25 compares each sound signal e.g. with a specific for the sound signal in question Reference value, only if the relevant one is exceeded Adequate signal quality is assumed for the reference value becomes. However, the signal quality can also be achieved using a signal processor determined by spectral analysis or the like become. If the signal in question is an identifier contains, which is only sent with sufficient quality, can the monitoring device 25 contain a circuit the on such (possibly continuously included or only sent at the beginning of the transmission) and "releases" the signal in question.

    Um zu vermeiden, daß der Benutzer durch zu häufiges Umschalten der Tonsignale oder zu häufiges Ändern des Mischungsverhältnisses mehrerer Tonsignale gestört wird, enthält die Überwachungseinrichtung 25 eine Schaltung, die jede Änderung nur nach Ablauf einer vorbestimmten Zeitspanne bzw. mit einer bestimmten Hysterese durchführt. Gemäß einer Weiterbildung der Erfindung kann diese Hysterese mittels eines Wählschalters oder dergleichen vom Benutzer geändert werden, so daß jeder Benutzer des Hörgeräts die optimale Arbeitsweise der Überwachungseinrichtung 25 selbst wählen kann.To avoid the user from switching too often sound signals or changing the mixing ratio too often contains several sound signals the monitor 25 a circuit that each Change only after a predetermined period of time or with a certain hysteresis. According to one This hysteresis can be further developed by means of a selector switch or the like changed by the user be so that each user of the hearing aid the optimal Select the mode of operation of the monitoring device 25 yourself can.

    In Fig. 2 ist ein zweites Ausführungsbeispiel der Erfindung gezeigt, das sich vom ersten Ausführungsbeispiel dadurch unterscheidet, daß für jedes Tonsignal eine Pegelanpassungseinrichtung 21, 22 bzw. 23 vorgesehen ist. Die weiteren Elemente dieses Hörgeräts entsprechen denen des Ausführungsbeispiels der Fig. 1, weshalb auf eine erneute Erläuterung dieser Elemente verzichtet wird. Das Mikrofon 10 hat in der Regel eine andere Empfindlichkeit als die beiden Signalaufnehmer 11 und 12. Mit Hilfe der zusätzlichen Pegelanpassungseinrichtungen 21 bis 23 ist es der Überwachungseinrichtung 25 jedoch möglich, den Ausgangspegel der Tonsignale so einzustellen, daß beim Umschalten von einem Tonsignal auf ein anderes bzw. beim Mischen mehrerer Tonsignale im wesentlichen die gleiche Ausgangslautstärke erzielt werden kann. Aus Fig. 2 ist ferner ersichtlich, daß das im Pegel geänderte Ausgangssignal jeder Pegelanpassungseinrichtung 21 bis 23 einer Einrichtung 24 zugeführt wird, die die Auswahl bzw. das Mischen dieser abgeglichenen Signale durchführt.2 is a second embodiment of the invention shown that is from the first embodiment characterized in that a level adjustment device for each sound signal 21, 22 and 23 is provided. The other elements of this hearing aid correspond to those of the Embodiment of FIG. 1, which is why a renewed Explanation of these elements is omitted. The microphone 10 usually has a different sensitivity than that two signal pickups 11 and 12. With the help of the additional Level adjustment devices 21 to 23 it is the Monitoring device 25, however, possible the output level the sound signals so that when switching from one sound signal to another or when mixing several Sound signals essentially the same output volume can be achieved. From Fig. 2 it can also be seen that the level-changed output signal of each level adjustment device 21 to 23 fed to a device 24 the selection or mixing of these are compared Performs signals.

    Mit beiden Ausführungsformen - Fig. 1 und Fig. 2 - läßt sich auf einfache Weise im Zusammenwirken mit der Freisprecheinrichtung am Telefon eine Freisprechfunktion für den Hörgeräteträger realisieren. Die Stimme des Gesprächsteilnehmers am anderen Ende der Leitung wird induktiv an das Hörgerät übermittelt. Das von dem Hörgeräteträger Gesprochene wird über das Mikrofon der Freisprecheinrichtung am Telefon an den Teilnehmer am anderen Ende der Leitung übermittelt.
