Description
Die vorliegende Erfindung betrifft ein Hörgerät mit einem Akustikaufnehmer zur Aufnahme eines Akustiksignals, einem Induktionsaufnhemer zur Aufnahme eines Induktionssignals und einer Steuereinrichtung zum Steuern des Hörgeräts. Darüber hinaus betrifft die vorliegende Erfindung ein entsprechendes Verfahren zur Steuerung eines Hörgeräts.The present invention relates to a hearing aid with a Acoustic transducer for recording an acoustic signal, a Induction recorders for recording an induction signal and a control device for controlling the hearing aid. About that in addition, the present invention relates to a corresponding one Method for controlling a hearing aid.
Hörgeräte werden in verschiedenartigen Hörsituationen eingesetzt und müssen dem Patienten jeweils gewünschte akustische Reize übermitteln. So will der Patient beispielsweise im Straßenverkehr zur Gefahrenwahrnehmung eine omnidirektionale Schallwahrnehmung und bei einem Gespräch mit einem Gesprächspartner eine gerichtete Schallwahrnehmung erfahren. Darüber hinaus sollte dem Hörgeräteträger sowohl mit schnurgebundenen als auch mit schnurlosen Telefonen sowie mit Mobiltelefonen ein störungsarmes Telefonieren möglich sein.Hearing aids are used in different hearing situations used and must be desired by the patient convey acoustic stimuli. So the patient wants for example in road traffic to perceive a hazard omnidirectional sound perception and during a conversation with a conversation partner a directed sound perception Experienced. In addition, the hearing aid wearer should both with corded as well as cordless phones as well low-interference calls possible with mobile phones his.
Üblicherweise sind Hörgeräte in der Lage, den unterschiedlichen Hörsituationen dadurch gerecht zu werden, dass sie von dem Hörgeräteträger in unterschiedliche Hörprogramme geschaltet werden können. Ein typisches Hörprogramm ist das Telefonhörprogramm, bei dem die akustischen Signale, die das Mikrofon des Hörgeräts aufnimmt, entsprechend dem Spektrum von Telefonsignalen gefiltert werden, um störende Umgebungsgeräusche in anderen Spektralbereichen zu unterdrücken. Hochwertige Hörgeräte verfügen in der Regel über mehrere Mikrofone, die durch ein spezielles Hörprogramm zur Erzielung einer Richtwirkung zusammengeschaltet werden können.Hearing aids are usually able to to cater to different listening situations that they differ from the hearing aid wearer Hearing programs can be switched. A typical one Hearing program is the telephone hearing program in which the acoustic signals picked up by the hearing aid microphone, filtered according to the spectrum of telephone signals be to distracting ambient noise in others Suppress spectral ranges. High quality hearing aids usually have multiple microphones through one special hearing program to achieve directivity can be interconnected.
Neben einem oder mehreren Mikrofonen sind in Hörgeräten vielfach Induktionsaufnehmer vorgesehen, die einen Hörspulenbetrieb ermöglichen. Damit wird gewährleistet, akkustische Signale von einem Telefongerät, das über eine Hörspule verfügt, induktiv auf das Hörgerät zu übertragen. Ein derartiger Hörspulenbetrieb hat bekanntermaßen den Vorteil, dass Störschall aus der Umgebung beim Telefonieren über das Hörgerät nicht übertragen wird.In addition to one or more microphones are in hearing aids often provided induction sensors, the one Enable hearing coil operation. This ensures Acoustic signals from a telephone device, which over a Hearing coil has to be transmitted inductively to the hearing aid. Such a hearing coil operation is known to have the Advantage that noise from the environment when calling is not transmitted via the hearing aid.
Das Schalten bzw. Steuern von Hörgeräten erfolgt üblicherweise durch Schalter, Taster oder Steller am Gehäuse des Hörgeräts. Bei sogenannten Hinter-dem-Ohr-Hörgeräten (HdO) stellt dies kein Problem dar, da sie über eine entsprechende Baugröße verfügen. Bei sogenannten In-dem-Ohr-Hörgeräten (IdO), die sich in der Ohrmuschel oder sogar ausschließlich im Gehörgang (CIC-Geräte; complete in the channel) befinden, ergibt sich die Schwierigkeit, manuelle Geber am Hörgerät selbst anzubringen, da ihre Baugröße derart gering ist. Die IdO-Hörgeräte werden daher in der Regel automatisch gesteuert und geschaltet.Hearing aids are switched or controlled usually by switches, buttons or actuators on the housing of the hearing aid. In so-called behind-the-ear hearing aids (BTE) this is not a problem as it has a have the appropriate size. In so-called in-the-ear hearing aids (ITE) that are in the pinna or even only in the ear canal (CIC devices; complete in the channel), the difficulty arises, manual Attach encoder to the hearing aid itself, because their size is such is low. The ITE hearing aids are therefore usually automatically controlled and switched.
Bekanntermaßen kann ein Hörgerät automatisch in ein Telefonhörprogramm geschaltet werden, falls ein Magnetfeld detektiert wird, das vom Hörer eines Telefongeräts abgestrahlt wird. Hierzu ist in der Patentschrift DE 31 09 049 C2 ausgeführt, dass durch die Verwendung von Elementen, die unter Einfluss eines magnetischen Feldes im Sinne eines Schalters ihre elektrischen Eigenschaften, etwa die Leitfähigkeit, ändern, zur Betätigung des Schaltvorgangs noch das Anlegen eines Magnetfelds erforderlich ist. Als Schaltglied kann etwa ein verschiebbarer Magnet benutzt werden. Die eigentlichen Kontaktelemente fallen unter die Kategorie berührungsloser Schalter und können z. B. als sogenannte Schutzrohrkontakte, die auch unter der Bezeichnung Reed-Kontakte bekannt sind bzw. als Magnetfeldhalbleiter, die auch Hall-Generatoren sind, ausgebildet sein. Für den Schaltvorgang ist es also notwendig, dass das Hörgerät ein statisches Magnetfeld registriert, damit es die induktiv empfangenen Signale gemäß dem Telefonhörerprogramm verstärkt. As is known, a hearing aid can automatically fit into one Telephone hearing program can be switched if a magnetic field is detected by the handset of a telephone device is emitted. For this purpose, the patent specification DE 31 09 049 C2 stated that by using elements, under the influence of a magnetic field in the sense of a Switch their electrical properties, such as the Conductivity, change, to actuate the switching process yet the application of a magnetic field is required. As Switching element can be used as a sliding magnet become. The actual contact elements fall under the Category non-contact switches and can e.g. B. as so-called thermowell contacts, which are also called Reed contacts are known or as magnetic field semiconductors Hall generators are also formed. For the Switching process, it is therefore necessary for the hearing aid to be on static magnetic field registered to make it inductive received signals amplified according to the handset program.
Schwierigkeiten beim automatischen Umschalten in ein Telefonhörprogramm bzw. in einen Hörspulenbetrieb treten regelmäßig dann auf, wenn beispielsweise in Hörsälen das Signal zwar durch Schleifen im Boden induktiv übertragen wird, dabei aber kein magnetisches Gleichsignal vorliegt. Das gleiche Problem tritt bei mobilen und schnurlosen Telefonen auf, die piezoelektrische Hörer aufweisen. Ebenso treten beim manuellen Umschalten Probleme auf, wenn der Hörgeräteträger beim Telefonieren mit einem Mobiltelefon in gewohnter Weise in den Hörspulenbetrieb schaltet, das Mobiltelefon aber nicht zur induktiven Übertragung von Hörsignalen ausgelegt ist.Difficulty in automatically switching to one Telephone hearing program or in a hearing coil operation regularly when, for example, in lecture halls Signal transmitted inductively by loops in the floor is, but there is no DC magnetic signal. The same problem occurs with mobile and cordless phones that have piezoelectric earphones. Likewise, when manual switching problems when the hearing aid wearer when calling with a mobile phone in the usual way switches to the hearing coil mode, but the mobile phone does not is designed for the inductive transmission of audible signals.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, das automatische Schalten und Steuern von Hörgeräten im Hinblick auf die jeweilige Hörsituation zu verbessern.The object of the present invention is therefore the automatic switching and control of hearing aids in the To improve with regard to the respective hearing situation.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Hörgerät mit einem Akustikaufnehmer zur Aufnahme eines Akustiksignals, einem Induktionsaufnehmer zur Aufnahme eines Induktionssignals und einer Steuereinrichtung zum Steuern des Hörgeräts, sowie einer Vergleichseinrichtung zum Vergleichen des aufgenommenen Akustiksignals mit dem aufgenommenen Induktionssignal und Liefern eines Vergleichsergebnisses an die Steuereinrichtung zur Steuerung des Hörgeräts anhand des Vergleichsergebnisses.According to the invention, this object is achieved by a hearing aid with an acoustic sensor for recording an acoustic signal, an induction pickup to hold a Induction signal and a control device for controlling the Hearing aid, and a comparison device for comparison of the recorded acoustic signal with the recorded Induction signal and delivering a comparison result the control device for controlling the hearing aid based on the Comparison result.
Darüber hinaus wird die genannte Aufgabe gelöst durch ein Verfahren zum Steuern eines Hörgeräts durch Aufnehmen eines Akustiksignals und eines Induktionssignals, Vergleichen des Akustiksignals mit dem Induktionssignal und Steuern des Hörgeräts anhand des Vergleichs.In addition, the stated task is solved by a Method for controlling a hearing aid by picking up a Acoustic signal and an induction signal, comparing the Acoustic signal with the induction signal and controlling the Hearing aid based on the comparison.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. Preferred developments of the invention result from the Dependent claims.
Durch das erfindungsgemäße Vergleichen des Induktionssignals von dem Induktionsaufnehmer und des Mikrofonsignals von dem Akustikaufnehmer kann durch vorgegebene Entscheidungskriterien automatisch entschieden werden, ob das Hörgerät in einen Hörspulenbetrieb oder einen Mikrofonbetrieb geschaltet wird. Das Hörgerät optimiert dadurch automatisch den Schallempfang für den Hörgeräteträger.By comparing the induction signal according to the invention from the induction pickup and the microphone signal from that Acoustic transducers can be specified by Decision criteria are automatically decided whether that Hearing aid in a hearing coil mode or a microphone mode is switched. As a result, the hearing aid optimizes automatically the sound reception for the hearing aid wearer.
Die vorliegende Erfindung wird nun anhand der beigefügten
Zeichnungen näher erläutert, in denen zeigen:
Die nachfolgend beschriebenen Ausführungsbeispiele stellen bevorzugte Ausführungsformen der Erfindung dar.The exemplary embodiments described below represent preferred embodiments of the invention.
Ein erfindungsgemäßes digitales Hörgerät 1 umfasst gemäß Fig.
1 zwei Mikrofone 2, 3 und optional eine Hörspule 4. Die
beiden Mikrofone 2, 3 nehmen den entsprechenden Schall auf
und wandeln ihn zur Weiterverarbeitung für die
Steuereinrichtung 5. In der Hörspule bzw. dem
Induktionsaufnehmer 4 wird das von einer Induktionsanlage
oder einer Telefonspule abgestrahlte Signal induktiv
aufgenommen und zur Weiterverarbeitung ebenfalls an die
Steuereinrichtung 5 weitergeleitet. Die Steuereinrichtung 5
analysiert die von den Aufnehmern 2, 3 und 4 erhaltenen
Signale und steuert bzw. schaltet die Übertragungsfunktion
zwischen den Aufnehmern 2, 3, 4 und einem Lautsprecher 6.A
Erfindungsgemäß wird nun zum Schalten bzw. Steuern des
Hörgeräts bzw. seiner Hörprogramme und/oder
Übertragungsparameter nicht ein Signal eines Schalters oder
ein konstantes Signal eines externen Geräts, wie z. B. das
statische Magnetfeldsignal einer Telefonhörerspule,
verwendet. Vielmehr wird gemäß der vorliegenden Erfindung
parallel zu den Signalen der Mikrofone die Signale des
Induktionsaufnehmers 4 zum Schalten oder Steuern ausgenutzt.According to the invention for switching or controlling the
Hearing aid or its hearing programs and / or
Transmission parameters not a signal from a switch or
a constant signal from an external device such as B. that
static magnetic field signal of a telephone handset coil,
used. Rather, according to the present invention
parallel to the signals from the microphones, the signals from the
Es ist also vorgesehen, dass neben dem einen oder den
mehreren Mikrofonsignalen das von der Induktionsspule 4
aufgenommene Signal ständig überwacht und analysiert wird.
Dabei ist kontinuierlich zu untersuchen, ob es sich bei dem
Induktionssignal um ein Nutzsignal, z. B. Sprache mit gutem
Signal-Störabstand, handelt. Diese Aufgabe kann
beispielsweise von einem Klassifikationsalgorithmus
übernommen werden. Im Falle eines digitalen Hörgeräts mit
mehreren Signaleingängen (Mikrofone 2, 3 und Hörspule 4)
werden gleichzeitig die von den Mikrofonen 2, 3 aufgenommenen
akkustischen Signale und das von der Hörspule 4 aufgenommene
induktive Signal digitalisiert und analysiert. Der
Klassifikationsalgorithmus analysiert hierbei ständig alle
Eingangssignale hinsichtlich ihrer Kenngrößen wie Pegel,
Frequenz, Modulationsfrequenz, Modulationsgrad und/oder
geschätzter Signal-Rausch-Abstand etc. Aufgrund dieser
Kenngrößen wird nach einem bestimmten Verfahren, z. B.
mittels Bayes'schem Klassifikator, neuronalem Netzwerk,
Fuzzy-Controller etc., entschieden, welches der
Eingangssignale zu bevorzugen ist. Das entsprechende
Eingangssignal wird für die Weiterverarbeitung automatisch
gewählt. Demnach wird gemäß Fig. 2 in den Hörspulenbetrieb
geschaltet, wenn das Induktionssignal besser ist als das
Mikrofonsignal. Andernfalls schaltet das Hörgerät automatisch
in den Mikrofonbetrieb.It is therefore envisaged that in addition to one or the other
several microphone signals from the
Bei Bedarf kann auch eine manuelle Eingriffsmöglichkeit mittels bekannter Schalter, Taster etc. für den Hörgeräteträger vorgesehen werden. Dies könnte beispielsweise dann von Vorteil sein, wenn der Hörgeräteträger in einem Hörsaal das Induktionssignal zu empfangen wünscht und sich Personen in seiner Umgebung verhältnismäßig laut unterhalten, so dass das Hörgerät automatisch unter Umständen in den Mikrofonbetrieb schalten würde.If necessary, manual intervention is also possible by means of known switches, buttons etc. for the Hearing aid wearers are provided. For example then be advantageous if the hearing aid wearer in one Lecture hall wishes to receive the induction signal and itself Entertain people in his area relatively loudly, so that the hearing aid may automatically move into the Would switch microphone operation.
Die parallele Analyse des Induktionssignals und des Mikrofonssignals ist verhältnismäßig aufwendig. Zur Minimierung des Aufwands kann die Analyse des Induktionssignals beispielsweise im Zeitmultiplex-Verfahren mit solchen Signalverarbeitungsblöcken erfolgen, die auch für das Mikrofonsignal verwendet werden.The parallel analysis of the induction signal and the Microphone signal is relatively complex. to The analysis of the data can be minimized Induction signal, for example in the time division multiplex method with such signal processing blocks that are also for the microphone signal can be used.
Anhand des Vergleichsergebnisses nach der Analyse kann das Hörgerät geschaltet bzw. gesteuert werden. So kann im Rahmen des jeweiligen Schalt- bzw. Steuervorgangs die Quelle des das Eingangssignals als Hörgeräteparameter automatisch gewählt werden. Ferner kann das Hörgerät in einem Hörspulenbetrieb und ein damit verbundenes Hörprogramm geschaltet werden, wenn das Induktionssignal besser als das Signal des oder der Mikrofone ist. Ebenso kann die Filterbandbreite des Hörgeräts reduziert werden, wenn das Hörgerät ein Telefonieren registriert, bei dem zwar ein Induktionssignal vorhanden, das Mikrofonsignal aber besser ist.Based on the comparison result after the analysis, this can be done Hearing aid can be switched or controlled. So in the frame of the respective switching or control process, the source of the Input signal automatically selected as a hearing aid parameter become. The hearing aid can also operate in a hearing coil and an associated hearing program can be switched if the induction signal better than the signal of the or Microphones is. Likewise, the filter bandwidth of the hearing aid be reduced when the hearing aid is making a phone call registered, in which an induction signal is present, the Microphone signal but is better.
Dies bedeutet, dass neben dem Steuern einzelner Parameter auch mehrere Parameter, die in sogenannten Hörprogrammen zusammengefasst sind, gleichzeitig verändert werden können, indem von einem Hörprogramm in ein anderes geschaltet wird. So kann beispielsweise in einem Hörsaal das Hörgerät, falls kein Induktionssignal vorhanden ist, von einem Hörprogramm für omnidirektionales Hören in ein Hörprogramm für gerichtetes Hören umgeschaltet werden.This means that in addition to controlling individual parameters also several parameters in so-called hearing programs are summarized, can be changed at the same time, by switching from one hearing program to another. For example, the hearing aid can be used in an auditorium if there is no induction signal from a hearing program for omnidirectional listening in a hearing program for directional hearing can be switched.
Da die Eingangssignale der Induktionsspule 4 und des oder der
Mikrofone 2, 3 ständig aufgenommen und analysiert werden,
kann in einer Weiterentwicklung des erfindungsgemäßen
Hörgeräts vorgesehen werden, dass die beiden Eingangssignale
für die Übertragung im Hörgerät gemischt werden. So ist es
für den Hörgeräteträger durchaus vorteilhaft, er in einem
Hörsaal im Hörspulbetrieb zu einem gewissen Maße auch
Umgebungsgeräusche wahrnehmen kann. Dies ist dann notwendig,
wenn sich der Nachbar des Hörgeräteträgers mit diesem leise
unterhalten will. Mit anderen Worten, die Steuerung des
Hörgeräts kann auch so erfolgen, dass nicht rein alternativ
in einem Hörspulen- oder Mikrofonbetrieb, sondern auch in
einen Mischbetrieb, bei dem die jeweiligen Pegel entsprechend
zu wählen sind, geschaltet werden kann.Since the input signals of the
