Definitions
- the present invention relates to a hearing aid with a plurality of microphones, a noise detection device for detecting a wind-induced noise and for outputting a corresponding detection signal and a signal processing device for driving the plurality of microphones in response to the detection signal. Moreover, the present invention relates to a corresponding method for controlling a plurality of microphones of a hearing device.
- Hearing aids which also allow direction-dependent hearing, in principle have a higher sensitivity to wind due to the forward drawn position of the microphones.
- the low-frequency pseudo sound caused by turbulent currents on the head and on the auricle (pinna) or the edge of the auricle (helix) is particularly noticeable. This pseudo sound is audible only in the near field and occurs at the pinna and in the back of the head. Since the microphones are due to the function immediately adjacent to the pinna, this pseudo sound is amplified by the hearing aid and leads to an unpleasant noise ("rumble").
- a similar hearing aid is for example from the document WO 03/059010 A1 known.
- This hearing aid has two microphones that have different sensitivity to wind noise. The wind noise level of one of the Microphones are recorded and this signal is used to decide which of the two microphones should provide the input signal for further signal processing. However, it can not be ascertained whether the microphone with the generally lower wind sensitivity actually delivers a lower wind noise signal in the specific situation.
- a hearing aid with adaptive adaptation of the input transducer known. For example, when wind is detected, not only the transducers but also, for example, the signal filtering are adjusted. Specifically, it is proposed to switch from the directional operation to the omnidirectional operation when wind noise is detected.
- the windshielded microphone may be used as the input transducer.
- the object of the present invention is therefore to further reduce the sensitivity of hearing aids to disturbing wind.
- this object is achieved by a hearing device with a microphone device having a plurality of microphones, a noise detection device for detecting a noise caused by wind and for outputting a corresponding detection signal and a signal processing device for driving the microphone device in response to the detection signal, wherein each noise level by the noise detection device of at least two of the a plurality of microphones can be detected and in the signal processing device, the at least two noise levels comparable with each other and a corresponding drive signal to the microphone device can be output.
- the invention provides a method for controlling a plurality of microphones of a hearing device by detecting a wind-induced noise and outputting a corresponding detection signal and driving the plurality of microphones in response to the detection signal, wherein a noise level of at least two of the plurality of microphones is detected, the at least two noise levels compared with each other and the microphones are driven according to the comparison result.
- the invention is based on the idea of measuring the actual noise level caused by wind on a plurality of microphones of the hearing device and controlling the microphones as a function thereof.
- the wind noise intensity is measured at several hearing device points and the hearing device is controlled accordingly.
- the drive signal is a signal for driving the microphones in an omnidirectional operation.
- an increase in the signal-to-noise ratio can be achieved.
- the noise generated by the wind in particular, is constantly detectable with the noise-determining device and the microphones can be correspondingly continuously driven by the signal-processing device. As a result, the microphones can be controlled and switched depending on the situation.
- the microphone with the lowest noise level can be recognized by the signal processing device, this microphone can be used for omnidirectional operation and / the other microphones can be switched off. As a result, only the microphone that is least affected by the wind can be used for the signal processing.
- the signal processing device can have a classifier for selecting the microphone (s) for the further signal processing on the basis of the noise level. In this way, the microphones can be targeted switch to the appropriate operation.
- Directional hearing aids have several microphones that functionally not at the same point of the hearing aid have their outlet. Therefore, when the hearing aid is worn, the outlet openings are also not placed at the wearer's ear at the same point of the head or pinna. Consequently, the individual microphones, as shown in Figure 1, a different wind sensitivity depending on the location of the ear and of course the shape of the pinna. In the present example, not only the wind is detected with the microphone array in the hearing aid (two to three microphones), but also measured at the same time by internal level meter frequency-specific wind noise. According to FIG.
- a first noise spectrum R1 results for a first microphone, a second noise spectrum R2 for a second microphone and a third noise spectrum for a second microphone a third noise spectrum R3.
- the level of the third noise spectrum R3 of the third microphone is below the noise levels of the other two microphones in all spectral ranges. A corresponding comparison would therefore lead to the result that the third microphone is least affected by the wind in the entire spectral range. Thus, in the current situation, it should be used as the sole omnidirectional microphone.
- the noise spectrum R2 is higher than the noise spectrum R1 in the middle frequency range and lower than this in the higher frequency range. If a hearing aid were equipped only with these two microphones, then these two microphones could be switched in the current wind situation so that the second microphone in the low and medium frequency range and the first microphone in the higher frequency range serves as omnidirectional microphone. This means that the microphones for each wind situation are frequency-specifically controlled or switched.
- the comparison of the level spectra can be carried out, for example, with the aid of adjustable threshold values.
- the aid of a classifier With the aid of a classifier, the more suitable for the wind situation omni-directional microphone signal or a combination of microphone signals (eg, sum of two or three microphone signals) can be selected.
- a further reduction of the wind noise induced by pseudo noise can be effected, depending on the wind speed / turbulence intensity and position of the microphones on the head.
- the hearing aid has three microphones M1, M2 and M3.
- the noise signals of all three microphones M1, M2 and M3 are measured in a level meter P.
- a downstream comparator C compares the level spectra optionally with certain thresholds.
- a subsequent classifier K decides, based on the comparisons, which microphone is to be used for signal processing in the hearing aid as an input signal converter. Controlled by the signal from the classifier K, a multiplexer M switches the corresponding signal for omnidirectional operation for further signal processing.
- a wind detector W determines whether there is any wind noise at the microphones. Only when wind is detected, the multiplexer M is activated and it is the appropriate microphone, if necessary frequency-specific switched through. If, however, no wind is detected, the signals of all microphones are used to obtain a directivity. It may also be useful to switch a pure omni-directional signal, formed from signals from M1 or any combination of M1 and Mn, into a wind-reduced omnidirectional signal from another microphone M2 or M3.

Description
Die vorliegende Erfindung betrifft ein Hörgerät mit mehreren Mikrofonen, einer Rauschdetektionseinrichtung zur Detektion eines durch Wind hervorgerufenen Rauschens und zur Ausgabe eines entsprechenden Detektionssignals sowie einer Signalverarbeitungseinrichtung zum Ansteuern der mehreren Mikrofone in Abhängigkeit von dem Detektionssignal. Darüber hinaus betrifft die vorliegende Erfindung ein entsprechendes Verfahren zum Steuern von mehreren Mikrofonen eines Hörgeräts.The present invention relates to a hearing aid with a plurality of microphones, a noise detection device for detecting a wind-induced noise and for outputting a corresponding detection signal and a signal processing device for driving the plurality of microphones in response to the detection signal. Moreover, the present invention relates to a corresponding method for controlling a plurality of microphones of a hearing device.
Hörgeräte, die auch richtungsabhängiges Hören erlauben, haben prinzipiell durch die nach vorne gezogene Position der Mikrofone eine höhere Empfindlichkeit gegenüber Wind. Besonders bemerkbar macht sich dabei der durch turbulente Strömungen am Kopf und an der Ohrmuschel (Pinna) bzw. dem Rand der Ohrmuschel (Helix) verursachte tieffrequente Pseudoschall. Dieser Pseudoschall ist nur im Nahfeld hörbar und tritt an der Pinna und im hinteren Kopfbereich auf. Da nun die Mikrofone funktionsbedingt unmittelbar neben der Pinna liegen, wird dieser Pseudoschall durch das Hörgerät verstärkt aufgenommen und führt zu einem unangenehmen Geräusch ("Rumpeln").Hearing aids, which also allow direction-dependent hearing, in principle have a higher sensitivity to wind due to the forward drawn position of the microphones. The low-frequency pseudo sound caused by turbulent currents on the head and on the auricle (pinna) or the edge of the auricle (helix) is particularly noticeable. This pseudo sound is audible only in the near field and occurs at the pinna and in the back of the head. Since the microphones are due to the function immediately adjacent to the pinna, this pseudo sound is amplified by the hearing aid and leads to an unpleasant noise ("rumble").
Bislang hat man mit Hilfe zweier aktiver Mikrofone bei einem direktionalen Hörgerät Wind detektiert und das Hörgerät von dem Direktional-Modus in den Omni-Direktional-Modus automatisch umgeschaltet. Bei Bedarf wird zusätzlich im Omni-Direktional-Modus die Verstärkung in den tiefen Frequenzbändern reduziert. Damit lässt sich eine nicht immer ausreichende Reduktion des unangenehmen Geräusches erzielen.So far, with the help of two active microphones with a directional hearing aid, wind has been detected and the hearing aid switched automatically from directional mode to omni-directional mode. If necessary, the gain in the low frequency bands is additionally reduced in omni-directional mode. Thus, a not always sufficient reduction of the unpleasant noise can be achieved.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, die Empfindlichkeit von Hörgeräten gegenüber störendem Wind weiter zu reduzieren.The object of the present invention is therefore to further reduce the sensitivity of hearing aids to disturbing wind.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Hörgerät mit einer Mikrofoneinrichtung mit mehreren Mikrofonen, einer Rauschdetektionseinrichtung zur Detektion eines durch Wind hervorgerufenen Rauschens und zur Ausgabe eines entsprechenden Detektionssignals und einer Signalverarbeitungseinrichtung zum Ansteuern der Mikrofoneinrichtung in Abhängigkeit von dem Detektionssignal, wobei durch die Rauschdetektionseinrichtung jeweils ein Rauschpegel von mindestens zwei der mehreren Mikrofone detektierbar ist und in der Signalverarbeitungseinrichtung die mindestens zwei Rauschpegel miteinander vergleichbar und ein entsprechendes Ansteuersignal an die Mikrofoneinrichtung ausgebbar ist.According to the invention, this object is achieved by a hearing device with a microphone device having a plurality of microphones, a noise detection device for detecting a noise caused by wind and for outputting a corresponding detection signal and a signal processing device for driving the microphone device in response to the detection signal, wherein each noise level by the noise detection device of at least two of the a plurality of microphones can be detected and in the signal processing device, the at least two noise levels comparable with each other and a corresponding drive signal to the microphone device can be output.
Darüber hinaus ist erfindungsgemäß vorgesehen ein Verfahren zum Steuern von mehreren Mikrofonen eines Hörgeräts durch Detektieren eines durch Wind hervorgerufenen Rauschens und Ausgeben eines entsprechenden Detektionssignals und Ansteuern der mehreren Mikrofone in Abhängigkeit von dem Detektionssignal, wobei jeweils ein Rauschpegel von mindestens zwei der mehreren Mikrofone detektiert wird, die mindestens zwei Rauschpegel miteinander verglichen und die Mikrofone entsprechend dem Vergleichsergebnis angesteuert werden.Moreover, the invention provides a method for controlling a plurality of microphones of a hearing device by detecting a wind-induced noise and outputting a corresponding detection signal and driving the plurality of microphones in response to the detection signal, wherein a noise level of at least two of the plurality of microphones is detected, the at least two noise levels compared with each other and the microphones are driven according to the comparison result.
Der Erfindung liegt der Gedanke zugrunde, den durch Wind hervorgerufenen tatsächlichen Rauschpegel an mehreren Mikrofonen des Hörgeräts zu messen und abhängig davon die Mikrofone zu steuern. Damit wird die Windgeräuschintensität, wie sie tatsächlich gegeben ist, an mehreren Hörgerätestellen gemessen und das Hörgerät entsprechend gesteuert.The invention is based on the idea of measuring the actual noise level caused by wind on a plurality of microphones of the hearing device and controlling the microphones as a function thereof. Thus, the wind noise intensity, as is actually the case, is measured at several hearing device points and the hearing device is controlled accordingly.
Vorzugsweise ist das Ansteuersignal ein Signal zum Ansteuern der Mikrofone in einen Omnidirektionalbetrieb. Durch diese Maßnahme kann eine Steigerung des Signal-Rausch-Abstands erzielt werden.Preferably, the drive signal is a signal for driving the microphones in an omnidirectional operation. By this measure, an increase in the signal-to-noise ratio can be achieved.
Darüber hinaus ist es vorteilhaft, wenn mit der Rauschdektionseinrichtung das insbesondere durch Wind hervorgerufene Rauschen ständig detektierbar ist und die Mikrofone durch die Signalverarbeitungseinrichtung entsprechend fortlaufend ansteuerbar sind. Dadurch können die Mikrofone situationsabhängig gesteuert und geschaltet werden.Moreover, it is advantageous if the noise generated by the wind, in particular, is constantly detectable with the noise-determining device and the microphones can be correspondingly continuously driven by the signal-processing device. As a result, the microphones can be controlled and switched depending on the situation.
Entsprechend einer besonderen Ausgestaltung des erfindungsgemäßen Hörgeräts ist durch die Signalverarbeitungseinrichtung das Mikrofon mit dem geringsten Rauschpegel erkennbar, dieses Mikrofon für den Omnidirektionalbetrieb nutzbar und das/die übrigen Mikrofone ausschaltbar. Dadurch lässt sich für die Signalverarbeitung ausschließlich dasjenige Mikrofon nutzen, das vom Wind am wenigsten beeinflusst wird.According to a particular embodiment of the hearing aid according to the invention, the microphone with the lowest noise level can be recognized by the signal processing device, this microphone can be used for omnidirectional operation and / the other microphones can be switched off. As a result, only the microphone that is least affected by the wind can be used for the signal processing.
Darüber hinaus kann die Signalverarbeitungseinrichtung einen Klassifikator zur Auswahl des/der Mikrofone für die weitere Signalverarbeitung anhand der Rauschpegel aufweisen. Auf diese Weise lassen sich die Mikrofone zielgerichtet in den entsprechenden Betrieb schalten.In addition, the signal processing device can have a classifier for selecting the microphone (s) for the further signal processing on the basis of the noise level. In this way, the microphones can be targeted switch to the appropriate operation.

- ein Prinzipschaltbild eines erfindungsgemäßen Hörgeräts.

Das nachfolgend näher geschilderte Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below represents a preferred embodiment of the present invention.
Direktionale Hörgeräte besitzen mehrere Mikrofone, die funktionsbedingt nicht an derselben Stelle des Hörgeräts ihre Austrittsöffnung haben. Daher sind die Austrittsöffnungen, wenn das Hörgerät getragen wird, am Ohr des Trägers auch nicht an derselben Stelle des Kopfes bzw. der Pinna platziert. Folglich zeigen die einzelnen Mikrofone, wie dies in FIG 1 dargestellt ist, eine unterschiedliche Windempfindlichkeit abhängig von der Lage am Ohr und natürlich auch von der Form der Pinna. In dem vorliegenden Beispiel wird mit dem Mikrofon-Array im Hörgerät (zwei bis drei Mikrofone) nicht nur der Wind detektiert, sondern auch gleichzeitig durch interne Pegelmesser jeweils frequenzspezifisch das Windgeräusch gemessen. Entsprechend FIG 1 ergibt sich für ein erstes Mikrofon ein erstes Rauschspektrum R1, für ein zweites Mikrofon ein zweites Rauschspektrum R2 und für ein drittes Mikrofon ein drittes Rauschspektrum R3. Der Pegel des dritten Rauschspektrums R3 des dritten Mikrofons liegt hier in sämtlichen Spektralbereichen unterhalb den Rauschpegeln der beiden anderen Mikrofone. Ein entsprechender Vergleich würde also zu dem Ergebnis führen, dass das dritte Mikrofon von dem Wind im gesamten Spektralbereich am wenigsten beeinflusst wird. Demnach sollte es in der aktuellen Situation als alleiniges omnidirektionales Mikrofon verwendet werden.Directional hearing aids have several microphones that functionally not at the same point of the hearing aid have their outlet. Therefore, when the hearing aid is worn, the outlet openings are also not placed at the wearer's ear at the same point of the head or pinna. Consequently, the individual microphones, as shown in Figure 1, a different wind sensitivity depending on the location of the ear and of course the shape of the pinna. In the present example, not only the wind is detected with the microphone array in the hearing aid (two to three microphones), but also measured at the same time by internal level meter frequency-specific wind noise. According to FIG. 1, a first noise spectrum R1 results for a first microphone, a second noise spectrum R2 for a second microphone and a third noise spectrum for a second microphone a third noise spectrum R3. The level of the third noise spectrum R3 of the third microphone is below the noise levels of the other two microphones in all spectral ranges. A corresponding comparison would therefore lead to the result that the third microphone is least affected by the wind in the entire spectral range. Thus, in the current situation, it should be used as the sole omnidirectional microphone.
Aus FIG 1 ist weiterhin zu entnehmen, dass das Rauschspektrum R2 im mittleren Frequenzbereich höher als das Rauschspektrum R1 und im höheren Frequenzbereich niedriger als dieses ist. Wäre ein Hörgerät nur mit diesen beiden Mikrofonen ausgestattet, so könnten diese beiden Mikrofone in der aktuellen Windsituation so geschaltet werden, dass das zweite Mikrofon im niedrigen und mittleren Frequenzbereich und das erste Mikrofon im höheren Frequenzbereich als Omnidirektionalmikrofon dient. Dies bedeutet, dass die Mikrofone für die jeweilige Windsituation frequenzspezifisch angesteuert bzw. geschaltet werden.It can also be seen from FIG. 1 that the noise spectrum R2 is higher than the noise spectrum R1 in the middle frequency range and lower than this in the higher frequency range. If a hearing aid were equipped only with these two microphones, then these two microphones could be switched in the current wind situation so that the second microphone in the low and medium frequency range and the first microphone in the higher frequency range serves as omnidirectional microphone. This means that the microphones for each wind situation are frequency-specifically controlled or switched.
Der Vergleich der Pegelspektren kann beispielsweise mit Hilfe einstellbarer Schwellenwerte erfolgen. Mit Hilfe eines Klassifikators lässt sich dann das für die Windsituation geeignetere omni-direktionale Mikrofonsignal bzw. eine Kombination von Mikrofonsignalen (z. B. Summe von zwei oder drei Mikrofonsignalen) auswählen. Somit lässt sich adaptiv eine weitere Reduktion des Windgeräusches induziert durch Pseudoschall bewirken und zwar abhängig von der Windgeschwindigkeit/Turbulenzstärke und Lage der Mikrofone am Kopf. Messungen am Kopf mit einem Windaufbau für Geschwindigkeiten bis 20 km/h zeigten, dass zusätzlich zu den oben genannten Maßnahmen (automatisches Umschalten von Direktional- in Omnidirektional-Betrieb und Reduktion der Verstärkung bei tieferen Frequenzen) durch gegebenenfalls frequenzselektive Auswahl des jeweils rauschärmeren omnidirektionalen Mikrofons weitere Verbesserungen bis zu 15 dB erreicht werden können.The comparison of the level spectra can be carried out, for example, with the aid of adjustable threshold values. With the aid of a classifier, the more suitable for the wind situation omni-directional microphone signal or a combination of microphone signals (eg, sum of two or three microphone signals) can be selected. Thus adaptively a further reduction of the wind noise induced by pseudo noise can be effected, depending on the wind speed / turbulence intensity and position of the microphones on the head. Measurements on the head with a wind structure for speeds up to 20 km / h showed that in addition to the above measures (automatic switching from directional to omnidirectional operation and reduction of gain at lower frequencies) by optionally frequency-selective selection of each noise-reduced omnidirectional microphone further Improvements of up to 15 dB can be achieved.
Der prinzipielle Aufbau eines erfindungsgemäßen Hörgeräts ist in FIG 2 wiedergegeben. Demnach besitzt das Hörgerät drei Mikrofone M1, M2 und M3. Die Rauschsignale aller drei Mikrofone M1, M2 und M3 werden in einem Pegelmesser P gemessen. Ein nachgeschalteter Comparator C vergleicht die Pegelspektren gegebenenfalls mit bestimmten Schwellwerten. Ein nachfolgender Klassifikator K entscheidet dann anhand der Vergleiche, welches Mikrofon für die Signalverarbeitung im Hörgerät als Eingangssignalwandler verwendet werden soll. Gesteuert durch das Signal vom Klassifikator K schaltet ein Multiplexer M das entsprechende Signal für den Omnidirektionalbetrieb für die weitere Signalverarbeitung durch.The basic structure of a hearing aid according to the invention is shown in FIG. Accordingly, the hearing aid has three microphones M1, M2 and M3. The noise signals of all three microphones M1, M2 and M3 are measured in a level meter P. A downstream comparator C compares the level spectra optionally with certain thresholds. A subsequent classifier K then decides, based on the comparisons, which microphone is to be used for signal processing in the hearing aid as an input signal converter. Controlled by the signal from the classifier K, a multiplexer M switches the corresponding signal for omnidirectional operation for further signal processing.
Parallel hierzu stellt ein Winddetektor W fest, ob überhaupt ein Windgeräusch an den Mikrofonen vorliegt. Nur dann, wenn Wind detektiert wird, wird der Multiplexer M aktiviert und es wird das geeignetere Mikrofon gegebenenfalls frequenzspezifisch durchgeschaltet. Wird hingegen kein Wind detektiert, so werden die Signale sämtlicher Mikrofone für die Erzielung einer Richtwirkung benutzt. Es kann auch sinnvoll sein, ein reines omni-direktionales Signal, gebildet aus Signalen von M1 oder einer beliebigen Kombination M1 und Mn, in ein windreduziertes omni-direktionales Signal von einem anderen Mikrofon M2 oder M3 umzuschalten.Parallel to this, a wind detector W determines whether there is any wind noise at the microphones. Only when wind is detected, the multiplexer M is activated and it is the appropriate microphone, if necessary frequency-specific switched through. If, however, no wind is detected, the signals of all microphones are used to obtain a directivity. It may also be useful to switch a pure omni-directional signal, formed from signals from M1 or any combination of M1 and Mn, into a wind-reduced omnidirectional signal from another microphone M2 or M3.
