Bei manchen Hörgeräten sind die typspezifischen Frequenzgangdaten jedoch noch nur sehr grobe Anhaltspunkte. Dies ist insbesondere bei IDO-Hörgeräten der Fall, bei denen die Schallschläuche in den Hörgeräten aufgrund der individuellen Bauformen der Otoplastiken stets unterschiedliche Längen besitzen, auch wenn es sich um die gleichen Hörgerätetypen handelt.Some hearing aids have the type-specific frequency response data but only very rough clues. This is special in the case of IDO hearing aids, where the sound tubes in the hearing aids due to the individual designs the earmolds always have different lengths, even if they are the same type of hearing aid.
In diesem Zusammenhang ist beispielsweise aus der Druckschrift EP 0 681 411 ein programmierbares Hörgerät bekannt, in dem Hörgerätekenndaten abgespeichert werden können. Hierzu ist ein entsprechender Speicher im Hörgerät vorzusehen, der bei Bedarf ausgelesen werden kann.In this context, for example, from the document EP 0 681 411 a programmable hearing device is known, in the hearing aid characteristics can be stored. For this is to provide a corresponding memory in the hearing aid, the can be read out if necessary.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, die Anpassung individueller Hörgeräte zu verbessern.The object of the present invention is therefore to to improve the customization of individual hearing aids.
Erfindungsgemäß wird dies gelöst durch ein Hörgerät mit einer Speichereinrichtung, in der Daten auslesbar eingespeichert sind, wobei die eingespeicherten Daten Frequenzgangdaten über den individuell für das vorliegende Hörgerät gemessenen Frequenzgang umfassen.This is achieved by a hearing aid with a Storage device in which data is stored in readable form are, wherein the stored data frequency response data via the frequency response measured individually for the present hearing aid include.
Darüber hinaus ist erfindungsgemäß vorgesehen ein Verfahren zum Anpassen eines Hörgeräts für einen Hörgeräteträger durch Auslesen von Frequenzgangdaten über den individuell für das vorliegende Hörgerät gemessenen Frequenzgang aus einem Speicher des Hörgeräts und Anpassen des Hörgeräts unter Verwendung der individuellen Frequenzgangdaten.In addition, the invention provides a method for adapting a hearing aid for a hearing aid wearer Read out frequency response data about the individual for the present hearing aid measured frequency response from a memory of the hearing aid and adjusting the hearing aid using the individual frequency response data.

Vorzugsweise wird der Frequenzgang in-situ gemessen, so dass die Frequenzgangdaten indirekte Informationen über den Gehörgang des Hörgeräteträgers beinhalten. Für diese Messung ist zwar ein Mikrophon oder Messschlauch im Ohrkanal notwendig, aber der Vorteil besteht darin, dass der Frequenzgang unter Berücksichtigung der spezifischen, akustischen Bedingungen im Ohrkanal des Träger bereits erfasst und im Hörgerät abgelegt ist, so dass Nachjustierungen schneller erfolgen können.Preferably, the frequency response is measured in situ, so that the frequency response data indirect information about the ear canal of the hearing aid wearer. For this measurement is while a microphone or measuring tube in the ear canal is necessary, but the advantage is that the frequency response is below Consideration of the specific acoustic conditions in the Ear canal of the wearer already detected and stored in the hearing aid is, so that readjustments can be made faster.

Das nachfolgend näher geschilderte Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below a preferred embodiment of the present invention represents.
Der Frequenzgang eines Hörgeräts wird typischerweise im Bereich von 100 Hz bis 10 kHz vermessen, wie dies an dem Beispiel von FIG 1 gezeigt ist. Hier sind die Frequenzgänge von zwei verschiedenen Verstärkungsstufen wiedergegeben. In jeder der beiden Verstärkungsstufen variiert der Frequenzgang in Abhängigkeit von der Länge des Schallschlauchs zwischen dem Hörer und dem IdO-Hörgeräteausgang. Die Länge des Schallschlauchs hängt unmittelbar von der Form der Otoplastik ab. Die Schallschlauchlängen rufen unterschiedliche Resonanzen hervor, was sich in den Frequenzgängen widerspiegelt. So findet sich beispielsweise bei dem in FIG 1 vermessenen Hörgerät die maximale Verstärkung bei einer Schallschlauchlänge von 17 mm in der Nähe von etwa 2400 Hz, während die maximale Verstärkung bei einer Schallschlauchlänge von 3 mm in der Nähe von 3000 Hz liegt. Darüber hinaus beträgt der Pegelunterschied zwischen den beiden Hörgeräten mit 17 mm und 3 mm Schlauchlänge bei 4,3 kHz etwa 11 dB. Dieser deutliche Pegelunterschied macht sich selbstverständlich bei der Anpassung deutlich bemerkbar.The frequency response of a hearing aid is typically in the range from 100 Hz to 10 kHz, as in the example of FIG. 1 is shown. Here are the frequency responses of reproduced two different gain levels. In every of the two amplification stages, the frequency response varies in Dependent on the length of the sound tube between the Handset and the IdO hearing aid output. The length of the sound tube depends directly on the shape of the earmold. The sound tube lengths call for different resonances what is reflected in the frequency response. So finds For example, in the case of the measured in Figure 1 hearing aid the maximum gain at a sound tube length of 17 mm near about 2400 Hz, while the maximum gain at a sound tube length of 3 mm in the vicinity of 3000 Hz. In addition, the level difference is between the two hearing aids with 17 mm and 3 mm Hose length at 4.3 kHz about 11 dB. This significant level difference goes without saying in the adaptation clearly noticeable.
Erfindungsgemäß ist daher vorgesehen, dass der individuelle Frequenzgang eines Hörgeräts in diesem abgelegt wird. Dazu wird eine Labormessung oder gegebenenfalls eine in-situ-Messung durchgeführt, wie sie in FIG 2 skizziert ist. Dabei ist ein IdO-Hörgerät HG in einem Ohrkanal OK eingesetzt. Das Ende eines Messschlauchs M oder ein Mikrophon befindet sich in dem Raum zwischen dem Trommelfell TF und dem Hörgerät HG, so dass der Ausgangsschallpegel des Hörgeräts HG in dem individuell geformten Ohrkanal gemessen werden kann. Das Hörgerät HG wird zur Aufzeichnung des Frequenzgangs von einem Messgerät MG über eine Steuerleitung SL angesteuert. Nach der Vermessung des individuellen Frequenzgangs durch das Messgerät MG wird der Frequenzgang einem Speicher S des Hörgeräts HG abgelegt. Aus diesem Speicher S ist der Frequenzgang jederzeit beispielsweise für eine Neueinstellung des Hörgeräts HG an das Programmiergerät eines Akustikers übertragbar. Der Speicher S in dem Hörgerät HG ist beispielsweise in Form eines EEPROM realisiert.According to the invention, it is therefore provided that the individual Frequency response of a hearing aid is stored in this. To is a laboratory measurement or, if necessary, an in-situ measurement carried out, as outlined in FIG. there is an IdO hearing aid HG inserted in an ear canal OK. The End of a measuring tube M or a microphone is located in the space between the eardrum TF and the hearing aid HG, so that the output sound level of the hearing aid HG in the individual shaped ear canal can be measured. The hearing aid HG is used to record the frequency response of a meter MG controlled via a control line SL. After the survey the individual frequency response through the meter MG is the frequency response to a memory S of the hearing aid HG stored. From this memory S is the frequency response at any time for example, for a new setting of the hearing aid HG transferable to the programmer of an acoustician. Of the Memory S in the hearing aid HG is for example in the form of a EEPROM realized.
Die Akustiker bzw. Kunden brauchen für die Anpassung eines Hörgeräts nur die Software für die Programmieroberfläche. Aktuelle Frequenzgangdaten und Updates dieser Daten müssen durch die erfindungsgemäße Lösung nicht an die Akustiker und Kunden verteilt werden. Vielmehr sind die frequenzspezifischen Hörgerätekurven für jedes Hörgerät unmittelbar in dem jeweiligen Hörgerät abgelegt. Dies bedeutet, dass bei unterschiedlichen Hörgerätetypen oder -versionen, aber auch bei Änderungen der Parameter am Hörgerät die Programmiersoftware unverändert bleiben kann. Eine entsprechende Software-Verteilungsaktion an die einschlägigen Anwender kann daher unterbleiben. Insbesondere kann auch ältere Software für neuere Hörgeräte verwendet werden. The acousticians or customers need for the adaptation of a Hearing aid only the software for the programming interface. current Frequency response data and updates of this data must by the solution according to the invention not to the acousticians and Customers are distributed. Rather, the frequency-specific Hearing aid curves for each hearing aid directly in the stored respective hearing aid. This means that at different Hearing aid types or versions, but also at Changes in the parameters on the hearing aid the programming software can remain unchanged. An appropriate software distribution action to the relevant users can therefore remain under. In particular, older software can also be used for newer ones Hearing aids are used.
Die Ablegung des individuellen Frequenzgangs in dem Hörgerät eröffnet aber auch die Möglichkeit, dass beliebige Kombinationen von Hörgerätekomponenten im Hörgerät verbaut werden. Jede dieser Komponenten, insbesondere auch die Hörer beeinflussen den individuellen Frequenzgang, der aber nun konkret abgespeichert ist. Letztlich wird immer die tatsächliche Komponentenkombination vermessen und der entsprechende Frequenzgang im Hörgerät gespeichert.The deposition of the individual frequency response in the hearing aid but also opens the possibility that any combinations Hearing aid components are installed in the hearing aid. each these components, in particular affect the listener the individual frequency response, but now stored in concrete is. Ultimately, the actual component combination always becomes measure and the corresponding frequency response stored in the hearing aid.
