Hörgeräte weisen vielfach Richtmikrofone auf, mit denen die Schallaufnahme richtungsabhängig gestaltet werden kann. So ist es beispielsweise zur Störgeräuschunterdrückung hilfreich, den Schall einer Störquelle, die in einer bestimmten Richtung registriert wird, weitestgehend zu dämpfen. Eine gattungsgemäße Hörervorrichtung ist beispielsweise aus der Druckschrift DE 197 21 157 bekannt.Hearing aids often have directional microphones with which the Sound recording can be designed direction-dependent.

The signal analysis unit takes one Directional analysis of the microphone signals. The can Strengthen signal components of the microphone signals in several Direction classes are divided.

Es ist jedoch nicht in jeder Situation günstig, das Geräusch einer Störquelle zu unterdrücken. So kann es beispielsweise gefährlich sein, wenn sich bei einem Waldspaziergang ein Radoder Mopedfahrer von hinten nähert, das Geräusch vom Hörgerät als Störgeräusch identifiziert und stark gedämpft wird. Es käme dann zu einer Schrecksituation, wenn der Hörgeräteträger mit dem unerwarteten, optischen Ereignis konfrontiert würde. Ähnliche Gefahrensituationen können bei Trägern von Kopfhörern und Head-Sets entstehen.However, it is not favorable in every situation, the noise to suppress a source of interference. For example, it can be dangerous when walking in a forest a Radoder Moped driver approaching from behind, the sound from the hearing aid is identified as a noise and strongly attenuated. It Then there would be a fright situation when the hearing aid wearer confronted with the unexpected optical event. Similar dangerous situations can occur with carriers of headphones and head sets are created.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Hörervorrichtung bereitzustellen, die den jeweiligen Träger z. B. in einer gefährlichen Situation besser schützt. Des Weiteren soll ein entsprechendes Verfahren zum Betreiben einer Hörervorrichtung angegeben werden.The object of the present invention is therefore to to provide a hearing device that the respective Carrier z. B. protects better in a dangerous situation. Furthermore, a corresponding method for operating an earphone device.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Hörervorrichtung mit einer Richtungsdetektionseinrichtung zum Detektieren einer Richtung, aus der von einer Schallquelle ein Schallsignal bei der Hörervorrichtung eintrifft, und einer Signalverarbeitungseinrichtung zum Verarbeiten des eintreffenden Schallsignals in Abhängigkeit von der detektierten Richtung, sowie einer Geräuschklassifikationseinrichtung zum Klassifizieren des von der Schallquelle eintreffenden Schallsignals in Signalklassen, so dass das eintreffende Schallsignal in der Signalverarbeitungseinrichtung auch in Abhängigkeit von der Signalklasse verarbeitbar ist.According to the invention, this object is achieved by a hearing device with a direction detection device for detecting a direction from a sound source Sound signal arrives at the earphone device, and a Signal processing device for processing the incoming Sound signal as a function of the detected Direction, and a noise classification device for Classifying the sound signal arriving from the sound source in signal classes, so that the incoming sound signal in the signal processing device also in dependence of the signal class is processable.

Ferner ist erfindungsgemäß vorgesehen ein Verfahren zum Betreiben einer Hörervorrichtung durch Detektieren einer Richtung, aus der von einer Schallquelle ein Schallsignal eintrifft, und Verarbeiten des eintreffenden Schallsignals in Abhängigkeit von der detektierten Richtung, Klassifizieren des von der Schallquelle eintreffenden Schallsignals in Signalklassen und Verarbeiten des eintreffenden Schallsignals auch in Abhängigkeit von der Signalklasse.Furthermore, the invention provides a method for Operate a hearing device by detecting a Direction, from the sound source of a sound signal arrives, and processing the incoming sound signal in Dependence on the detected direction, classify of the incoming sound source from the sound signal in signal classes and processing the incoming sound signal also depending on the signal class.

Vorzugsweise umfasst die Richtungsdetektionseinrichtung in der Hörervorrichtung ein adaptives Richtmikrofon. Die Richtcharakteristik des Richtmikrofons kann beispielsweise in Abhängigkeit von der Signalklasse eingestellt werden. Alternativ oder zusätzlich kann die Richtcharakteristik des Mikrofons aber auch in Abhängigkeit von der Frequenz eines eintreffenden Schallsignals eingestellt werden. Damit kann die eine oder die mehreren Einkerbungen bzw. Notches einer Richtmikrofoncharakteristik abhängig von der Signalklasse und/oder Frequenz in eine gewünschte Richtung gedreht werden. Bei vorgegebenen Signalklassen, die beispielsweise eine Gefahr signalisieren, kann somit die Störunterdrückung in ihrer Qualität entsprechend variiert werden.Preferably, the direction detection device comprises in the hearing device is an adaptive directional microphone. The directional characteristic of the directional microphone, for example, depending on be adjusted by the signal class. alternative or additionally, the directional characteristic of the microphone but also depending on the frequency of an incoming Sound signal can be adjusted. This can be the one or more notches or notches of a directional microphone characteristic depending on the signal class and / or Frequency can be turned in a desired direction.

Die Hörervorrichtung kann eine Signalausgabeeinrichtung zur Ausgabe eines Signals über die Signalklasse des eintreffenden Schallsignals an den Träger der Hörervorrichtung aufweisen. Ebenso kann von dieser Signalausgabeeinrichtung ein Signal über die Richtung des eintreffenden Schallsignals an den Träger der Hörervorrichtung ausgegeben werden. Das ausgegebene Signal kann dabei ein Sprachsignal oder ein taktiler Reiz, z.B. eine Vibration, sein. Damit ist es beispielsweise möglich, mit einer in einem Hörgerät generierten Sprache dem Hörgeräteträger in einer gefährlichen Situation eine Hilfestellung in Form von zusätzlicher Information zu geben. Diese zusätzliche Information kann beispielsweise die Art der Gefahrenquelle sowie deren Richtung betreffen. Die Integration eines entsprechenden informationsgebenden Systems in beispielsweise ein Hörgerät hat den Vorteil der lautheitsgerechten Präsentation einer Warnung.

Neben der bereits erwähnten Ausgestaltung der Hörervorrichtung als Hörgerät ist prinzipiell auch eine Ausgestaltung als Kopfhörer oder Head-Set denkbar. Damit ist es beispielsweise möglich, dass der Träger eines Kopfhörers auf das Schreien eines Babys aufmerksam gemacht wird. In addition to the already mentioned embodiment of the earphone device as a hearing aid is in principle also an embodiment as Headphone or headset conceivable. That's it, for example possible for the wearer of a headphone to scream a baby is alerted.

Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert, die ein Blockschaltbild eines erfindungsgemäßen Hörgeräts darstellt.The present invention will now be described with reference to the attached Drawing explained in more detail, which is a block diagram of an inventive Hearing device represents.

Das nachfolgend näher beschriebene Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below a preferred embodiment of the present invention represents.

Ein erfindungsgemäßes Hörgerät umfasst, wie es in der Figur schematisch dargestellt ist, ein Richtmikrofon RM. Dieses Richtmikrofon RM kann bei binauraler Versorgung durch die Mikrofone aus beiden Seiten realisiert werden. Das Richtmikrofon RM liefert an eine Signalverarbeitungseinrichtung VE neben den akustischen Signalen auch eine Richtungsinformation. Diese kann dazu verwendet werden, die Richtcharakteristik RC, die in der Figur gestrichelt angedeutet ist, des Richtmikrofons RM in gewünschter Weise auszurichten.A hearing aid according to the invention comprises, as in the figure is shown schematically, a directional microphone RM. This Directional microphone RM can be used in the binaural supply Microphones can be realized from both sides. The directional microphone RM supplies to a signal processing device VE In addition to the acoustic signals and a direction information. This can be used to the directional characteristic RC, which is indicated by dashed lines in the figure, the Align directional microphone RM in the desired manner.

Die Richtcharakteristik RC besitzt eine oder mehrere Einkerbungen bzw. Notches. In der Figur ist ein Notch N eingezeichnet. In der durch den Notch N gekennzeichneten Raumrichtung ist die Empfindlichkeit des Richtmikrofons RM am geringsten.The directional characteristic RC has one or more indentations or notches. In the figure, a Notch N is drawn. In the direction indicated by the Notch N spatial direction the sensitivity of the directional microphone RM is the lowest.

Üblicherweise wird die Richtcharakteristik RC eines Richtmikrofons RM an einer Störquelle Q ausgerichtet. Dies erfolgt, indem der oder die Notches N auf die Störquelle Q gerichtet werden. Durch dieses Drehen der Richtcharakteristik können Störgeräusche aus der Richtung der Störquelle Q wirksam unterdrückt werden.Usually, the directional characteristic RC of a directional microphone RM aligned to a source of interference Q. This happens, by the notches or N directed to the source of interference Q. become. By rotating the directional characteristic can Noise from the direction of the source of interference Q effectively suppressed become.

Der Einfachheit halber könnte die Richtungsinformation in Quadranten quantisiert werden. Dementsprechend könnte beispielsweise gemäß der vorliegenden Figur die Richtung der Störquelle Q mit "hinten links" bezeichnet werden.For simplicity, the direction information could be in Quadrants are quantized. Accordingly, for example according to the present figure, the direction of Source of interference Q with "back left".

Das Richtmikrofon RM liefert das aufgenommene Schallsignal gegebenenfalls auch vorverarbeitet an einen Geräuschklassifikator GK. Dieser teilt die empfangenen Signale in mehrere Signalklassen ein. Aufgrund dessen können Informationen über vorliegende Gefahren erhalten werden. Als Signalklassen sind beispielsweise denkbar: Babygeschrei, Fahrradklingeln, Straßenbahngeräusch, etc. Die aufgenommenen Schallsignale können auch lediglich hinsichtlich Lautheit klassifiziert werden. Aufgrund dieser Klassifikationsinformation kann von dem Hörgerät HG bzw. seiner Signalverarbeitungseinrichtung VE erkannt werden, aus welcher Richtung gegebenenfalls Gefahr droht.The directional microphone RM delivers the recorded sound signal possibly also preprocessed to a noise classifier GK. This divides the received signals into several Signal classes. Because of this, information about present dangers are obtained. As signal classes are for example conceivable: baby crying, bicycle bells, streetcar noise, etc. The recorded sound signals can also be classified only in terms of loudness. Because of this classification information, the hearing aid may HG or its signal processing device VE detected be, from which direction if necessary danger threatening.

Wenn sich nun beispielsweise eine Straßenbahn von links auf den Hörgeräteträger nähert, kann die Information über die Art des Geräusches und dessen Richtung von der Signalverarbeitungseinrichtung VE an einen Signalgenerator SG übermittelt werden. In ihm wird mittels eines bekannten Algorithmus ein Sprachsignal hinsichtlich der Störsignalquelle Q generiert. Dieses Sprachsignal wird an den Hörer H des Hörgeräts mit ausreichender Lautstärke weitergeleitet. Dadurch erhält der Hörgeräteträger die Informationen über die Störsignalquelle Q sicher auf akustischem Wege.If, for example, a tram starts from the left approaches the hearing aid wearer, the information about the art the noise and its direction from the signal processing means VE transmitted to a signal generator SG become. In it becomes by means of a well-known algorithm Speech signal with respect to the noise signal source Q generated. This speech signal is transmitted to the listener H of the hearing aid sufficient volume forwarded. This gives the Hearing aid wearer the information about the noise source Q safe on the acoustic way.

Alternativ oder zusätzlich kann der Signalgenerator SG auch einen in das Hörgerät HG integrierten Vibrator ansteuern, wenn das Signal einer bestimmten Signalklasse, z. B. Fahrradklingeln, eine bestimmte vorgegebene Schwelle übersteigt oder beim Näherkommen des Fahrrads lauter wird.Alternatively or additionally, the signal generator SG can also activate a vibrator integrated into the hearing aid HG, if the signal of a certain signal class, z. B. bicycle bells, exceeds a certain predetermined threshold or gets louder as the bike gets closer.

Die Signalsausgabe des Hörgeräts HG kann aber auch über andere Wege erfolgen. So ist es denkbar, dass das Hörgerät HG die gewonnene Information über Richtung und Art des Geräusches an ein Mobilfunktelefon übermittelt und dort einen entsprechenden Vibrationsalarm oder dergleichen auslöst.The signal output of the hearing aid HG can also be used over others Paths take place. So it is conceivable that the hearing aid HG the gained information about direction and type of noise transmitted to a mobile phone and there a corresponding Vibrating alarm or the like triggers.

Durch ein adaptives Richtmikrofon RM kann aber auch eine Aussage über die Bewegung eines Objekts erhalten werden. Dementsprechend kann bei einer Weiterbildung des erfindungsgemäßen Hörgeräts HG durch den Signalgenerator SG und den Hörer H eine Sprachausgabe erfolgen, mit der Informationen über die Bewegung des Objekts an den Hörgerätsträger ausgegeben werden.By an adaptive directional microphone RM but also a statement to be obtained via the movement of an object. Accordingly can in a development of the invention HG through the signal generator SG and the handset H a voice output, with the information about the Movement of the object to be issued to the hearing aid.
