Description
Die vorliegende Erfindung betrifft eine Hörvorrichtung mit einer Signalverarbeitungseinheit zum Ausführen eines Verarbeitungsalgorithmus. Darüber hinaus betrifft die vorliegende Erfindung ein entsprechendes Verfahren zum Ausführen eines Verarbeitungsalgorithmus einer Hörvorrichtung. Unter dem Begriff Hörvorrichtung wird hier insbesondere ein Hörgerät verstanden; allerdings fallen unter den Begriff aber auch andere tragbare akustische Geräte.The present invention relates to a hearing apparatus having a signal processing unit for executing a processing algorithm. Moreover, the present invention relates to a corresponding method for implementing a processing algorithm of a hearing device. The term hearing device is understood here in particular as a hearing device; however, the term also includes other portable acoustic devices.
Hörgeräte sind tragbare Hörvorrichtungen, die zur Versorgung von Schwerhörenden dienen. Um den zahlreichen individuellen Bedürfnissen entgegenzukommen, werden unterschiedliche Bauformen von Hörgeräten wie Hinter-dem-Ohr-Hörgeräte (HdO), In-dem-Ohr-Hörgeräte (IdO), Concha-Hörgeräte usw. bereitgestellt. Die beispielhaft aufgeführten Hörgeräte werden am Außenohr oder im Gehörgang getragen. Darüber hinaus stehen auf dem Markt aber auch Knochenleitungshörhilfen, implantierbare oder vibrotaktile Hörhilfen zur Verfügung. Dabei erfolgt die Stimulation des geschädigten Gehörs entweder mechanisch oder elektrisch.Hearing aids are portable hearing aids that are used to care for the hearing impaired. To meet the numerous individual needs, different types of hearing aids such as behind-the-ear hearing aids (BTE), in-the-ear hearing aids (IDO), Concha hearing aids, etc. are provided. The hearing aids listed by way of example are worn on the outer ear or in the ear canal. In addition, bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
Hörgeräte besitzen prinzipiell als wesentliche Komponenten einen Eingangswandler, einen Verstärker und einen Ausgangswandler. Der Eingangswandler ist in der Regel ein Schallempfänger, z. B. ein Mikrofon, und/oder ein elektromagnetischer Empfänger, z. B. eine Induktionsspule. Der Ausgangswandler ist meist als elektroakustischer Wandler, z. B. Miniaturlautsprecher, oder als elektromechanischer Wandler, z. B. Knochenleitungshörer, realisiert. Der Verstärker ist üblicherweise in eine Signalverarbeitungseinheit integriert. Dieser prinzipielle Aufbau ist in
Vorliegend richtet sich das Interesse auf In-dem-Ohr-Hörgeräte, bei denen mehrere Mikrofone zum Aufnehmen von Schallsignalen verwendet werden. Durch die Verwendung von mehreren Mikrofonen wird eine Direktionalität der Richtcharakteristik, d.h. eine Richtwirkung des Hörgerätes gewährleistet.In the present case, interest is focused on in-the-ear hearing aids, in which several microphones are used to record sound signals. Through the use of multiple microphones, directionality of the directional characteristic, i. ensures a directivity of the hearing aid.
Eine besonders rasche Herstellung individuell geformter Schalen von In-dem-Ohr-Hörgeräten lässt sich durch das so genannte rapid shell manufacturing (RSM) erreichen, bei dem elektronische Daten bezüglich der Form der Schalen verwendet werden. Beispielsweise werden bei In-dem-Ohr-Hörgeräten Mikrofone auf einem Faceplate positioniert. Die notwendigen Positionierungsdaten der Mikrofone, wie die Abstände der Mikrofonausgänge, werden der RSM-Software zur Verfügung gestellt. Da eine Hörgeräteschale jedoch individuell geformt ist und auch beim Tragen gehörgangspezifisch ausgerichtet ist, ist das Faceplate ebenso individuell ausgerichtet. Die Positionierung der Mikrofone wirkt sich unmittelbar auf die Direktionalität der Mikrofone aus. In der Regel sind die Positionierungsdaten für einen Faceplatetyp jedoch kundenunabhängig vorgegeben.A particularly rapid production of individually shaped shells of in-the-ear hearing aids can be achieved by the so-called rapid shell manufacturing (RSM), in which electronic data relating to the shape of the shells are used. For example, for in-the-ear hearing aids, microphones are positioned on a faceplate. The necessary positioning data of the microphones, such as the distances of the microphone outputs, are provided to the RSM software. However, since a hearing aid shell is individually shaped and is also specifically aimed at the ear when worn, the faceplate is also individually aligned. The positioning of the microphones has an immediate effect on the directionality of the microphones. As a rule, however, the positioning data for a faceplate type are specified independently of the customer.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, die Richtcharakteristik einer Hörvorrichtung, deren Schale insbesondere automatisch hergestellt wird, individuell anzupassen.The object of the present invention is therefore to adapt the directional characteristic of a hearing device whose shell is produced in particular automatically.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Hörsystem mit einer Hörvorrichtung einschließlich einer Signalverarbeitungseinheit zum Ausführen eines Verarbeitungsalgorithmus, und mit einer Herstellungssteuereinrichtung zum Bereitstellen mindestens eines konstruktionsbezogenen Parameters der Hörvorrichtung, wobei die Signalverarbeitungseinheit den Verarbeitungsalgorithmus auf der Grundlage des mindestens einen konstruktionsbezogenen Parameters der Hörvorrichtung oder eines daraus gewonnenen Steuerwerts ausführt, und wobei von der Herstellungssteuereinrichtung der Signalverarbeitungseinheit der mindestens eine konstruktionsbezogene Parameter der Hörvorrichtung oder der daraus gewonnene Steuerwert zur Verfügung gestellt ist.According to the invention, this object is achieved by a hearing system with a hearing device including a signal processing unit for executing a processing algorithm, and with a production control device for providing at least one design-related parameter of the hearing device, wherein the signal processing unit determines the processing algorithm based on the at least one design-related parameter of the hearing device or one thereof and at least one design-related parameter of the hearing device or the control value derived therefrom is provided by the production control device of the signal processing unit.
Darüber hinaus wird erfindungsgemäß bereitgestellt ein Verfahren zum Ausführen eines Verarbeitungsalgorithmus einer Hörvorrichtung, die eine Signalverarbeitungseinheit umfasst, durch Bereitstellen mindestens eines konstruktionsbezogenen Parameters der Hörvorrichtung durch eine Herstellungssteuereinrichtung, sowie Ausführen des Verarbeitungsalgorithmus der Hörvorrichtung durch die Signalverarbeitungseinheit auf der Grundlage des konstruktionsbezogenen Parameters oder eines daraus gewonnenen Steuerwerts, wobei von der Herstellungssteuereinrichtung der Signalverarbeitungseinheit der mindestens eine konstruktionsbezogene Parameter der Hörvorrichtung oder der daraus gewonnene Steuerwert zur Verfügung gestellt wird.Moreover, according to the present invention, there is provided a method of executing a processing algorithm of a hearing apparatus comprising a signal processing unit by providing at least one design-related parameter of the hearing apparatus by a manufacturing controller, and executing the processing algorithm of the hearing apparatus by the signal processing unit on the basis of the design-related parameter or one derived therefrom Control value, wherein from the manufacturing control device the signal processing unit, the at least one design-related parameters of the hearing device or the control value derived therefrom is provided.
In vorteilhafter Weise kann durch die Verwendung konstruktionsbezogener Daten oder eines daraus gewonnenen Steuerwerts ein Signalverarbeitungsalgorithmus der Hörvorrichtung besonders rasch, exakt und kundenabhängig verwirklicht werden. Insbesondere können somit speziell ausgebildete Verarbeitungsalgorithmen ausgeführt werden, die sich ohne die obigen Parameter nicht oder nur auf Umwegen realisieren ließen, und durch die die Wahrnehmbarkeit der Schallsignale deutlich verbessert werden kann.Advantageously, by using design-related data or a control value derived therefrom, a signal processing algorithm of the hearing device can be realized particularly quickly, precisely and customer-dependent. In particular, specially trained processing algorithms can thus be implemented which could not be realized without the above parameters or only by way of detours, and by which the perceptibility of the sound signals can be markedly improved.
Vorzugsweise können bei der Hörvorrichtung mindestens zwei Mikrofone ein Schallsignal empfangen, wobei ein Abstand zwischen den mindestens zwei Mikrofonen als der konstruktionsbezogene Parameter der Hörvorrichtung oder ein daraus gewonnener Steuerwert der Signalverarbeitungseinheit zur Verfügung gestellt ist, um eine vorzugsweise automatisierte Anpassung einer Richtcharakteristik der Hörvorrichtung auszuführen. Um nämlich optimale Richtwirkung zu erzielen, muss dem Algorithmus der Abstand zwischen den Mikrofonen bekannt sein, da danach entsprechende interne Verzögerungszeiten eingestellt werden müssen. Weiterhin hängt z.B. die Stärke des auftretenden Mikrofonrauschens vom Abstand der Mikrofone ab, was wiederum Auswirkungen auf Rauschunterdrückungsalgorithmen hat.Preferably, at least two microphones can receive a sound signal in the hearing device, wherein a distance between the at least two microphones as the construction-related parameters of the hearing device or a control value derived therefrom the signal processing unit is provided to perform a preferably automated adjustment of a directional characteristic of the hearing. In order to achieve optimum directivity, the algorithm must know the distance between the microphones, since then corresponding internal delay times must be set. Furthermore, e.g. the strength of the microphone noise occurring from the distance of the microphones, which in turn has effects on noise reduction algorithms.
Bei einer weiteren vorteilhaften Ausführungsform ist ein Orientierungswinkel einer Verbindungsgeraden zwischen den mindestens zwei Mikrofonen bezüglich einer vorgegebenen Gerade oder Ebene als der konstruktionsbezogene Parameter der Hörvorrichtung oder ein daraus gewonnener Steuerwert der Signalverarbeitungseinheit zur Verfügung gestellt, um eine Anpassung der Richtcharakteristik der Hörvorrichtung auszuführen. Der Winkel, in dem die Mikrofone bezogen auf die horizontale Blickrichtung des Hörvorrichtungs-Trägers angeordnet sind, erlaubt Rückschlüsse auf die maximal erreichbare Stärke der Richtwirkung und erlaubt damit ebenfalls eine Parametrierung, die optimal auf diesen konstruktionsbedingten Winkel angepasst ist.In a further advantageous embodiment, an orientation angle of a connecting straight line between the at least two microphones with respect to a given straight line or plane is provided as the construction-related parameter of the hearing device or a control value of the signal processing unit derived therefrom in order to carry out an adaptation of the directional characteristic of the hearing device. The angle at which the microphones are located relative to the horizontal viewing direction of the hearing aid wearer are, allows conclusions about the maximum achievable strength of the directivity and thus also allows a parameterization that is optimally adapted to this design-related angle.
Durch diese vorteilhaften Ausgestaltungen der erfindungsgemäßen Hörvorrichtung wird eine raschere individuelle Anpassung der Richtcharakteristik der Hörvorrichtung möglich, weil die konstruktionsbezogenen Parameter der Hörvorrichtung, die zur Anpassung der Richtcharakteristik herangezogen werden, bereits vor dem Tragen der Hörvorrichtung zur Verfügung gestellt sind. Auf der Grundlage der konstruktionsbezogenen Parameter, wie der Abstand der Mikrofone und der Orientierungswinkel, wird darüber hinaus eine besonders exakte automatisierte Anpassung der Richtcharakteristik gewährleistet.Through these advantageous embodiments of the hearing device according to the invention, a faster individual adaptation of the directional characteristic of the hearing device becomes possible because the construction-related parameters of the hearing device that are used to adapt the directional characteristic are already provided before wearing the hearing device. On the basis of the design-related parameters, such as the distance of the microphones and the orientation angle, moreover, a particularly accurate automated adjustment of the directional characteristic is ensured.
