Abstract
Description
Die Erfindung betrifft ein Verfahren zur Hörgeräteanpassung.The invention relates to a method for hearing aid adaptation.
Prinzipiell beruht die Schallquellenortung auf der Auswertung interauraler Pegel- und Laufzeitdiffererizen, die immer dann auftreten, wenn sich eine Schallquelle außerhalb der Medianebene des kopfbezogenen Koordinatensystems befindet. Dies befähigt den Menschen zu einer Auflösung von ca. 1° bei der Bestimmung der Schallquellenposition in der Horizontalebene. Der Stellenwert von Pegelunterschieden einerseits und Laufzeitunterschieden auf der anderen Seite für die Schallquellenortung kehrt sich mit steigender Frequenz um. Im Bereich unter 1.5 kHz spielt der interaurale Pegelunterschied kaum eine Rolle, da der Abstand beider Ohren im Verhältnis zur Wellenlänge gering ist. Für die Schallquellenortung werden bei tiefen Frequenzen dominierend interaurale Laufzeitdifferenzen ausgewertet. Anders stellt sich die Situation bei hohen Frequenzen dar. Durch die abschattende Wirkung des Kopfes bzw. die Beugung der Schallwellen am Kopf sind hier die Pegelunterschiede beider Ohrsignale für die Schallquellenortung nutzbar.In principle, the sound source location is based on the evaluation of interaural level and transit time differences, which always occur when a sound source is outside the median plane of the head-related coordinate system. This enables humans to achieve a resolution of approx. 1 ° when determining the sound source position in the horizontal plane. The significance of level differences on the one hand and differences in runtime on the other hand for the sound source location reverses with increasing frequency. In the range below 1.5 kHz, the interaural level difference hardly plays a role, since the distance between the two ears in relation to the wavelength is small. For sound source location, dominant interaural time differences are evaluated at low frequencies. The situation is different at high frequencies. Due to the shading effect of the head or the diffraction of the sound waves at the head here, the level differences of the two ear signals for sound source location can be used.
Die Regelversorgung eines hörgeschädigten Menschen ist eine beidseitige Versorgung mit Hörgeräten. Bei bekannten Hörgeräteanpassungsprozeduren wird dabei die Einstellung und Optimierung der Parameter beider Hörgeräte grundsätzlich mit den gleichen Methoden durchgeführt wie bei einer nur einseitigen Versorgung mit nur einem Hörgerät. Dazu werden bei bekannten Methoden die rechtsseitige Hörschwelle und die linksseitige Hörschwelle individuell geprüft und eine Anpassung der jeweiligen Hörgeräteverstärkungsparameter an die Hörschwelle des entsprechenden Ohres vorgenommen.The standard care of a hearing-impaired person is a bilateral supply of hearing aids. In known hearing aid fitting procedures, the setting and optimization of the parameters of both hearing aids is basically carried out using the same methods as in the case of only one-sided care with only one hearing aid. For this purpose, in known methods, the right-sided hearing threshold and the left-side auditory threshold are individually tested and an adaptation of the respective hearing-aid amplification parameters made to the hearing threshold of the corresponding ear.
Zusätzlich zu einer einseitigen Versorgung sollte das Zusammenwirken beider Hörgeräte berücksichtigt werden. Dazu ist es notwendig, u.a. den Effekt der binauralen Lautheitssummation zu berücksichtigen. Dies erfolgt bisher z.B. durch eine Verstärkungskorrektur um 3 dB im gesamten Frequenzbereich.In addition to a one-sided care, the interaction of both hearing aids should be considered. For this it is necessary u.a. to consider the effect of the binaural loudness summation. This has hitherto been done e.g. by a gain correction of 3 dB in the entire frequency range.
B. Seeber beschreibt in "Fortschritte der Akustik" der Deutschen Gesellschaft für Akustik, 2001 eine Einrichtung für Lokalisationsuntersuchungen, bei der ein kreisbogenförmiges Lautsprecherarray von elf Lautsprechern gepulste Rauschschalle aus den Richtungen -50 Grad links bis +50 Grad rechts zufällig darbieten. Die empfundene Schalleinfallsrichtung kann mit einem Lichtstrahl markiert werden, so dass Unterschiede zur Soll-Schalleinfallsrichtung bestimmt werden können.B. Seeber describes in "Advances in Acoustics" of the German Society for Acoustics, 2001, a device for localization investigations, in which a circular arc-shaped speaker array of eleven speakers pulsed noise noise from the directions -50 degrees left to +50 degrees right to present. The perceived sound incidence direction can be marked with a light beam so that differences to the desired sound incidence direction can be determined.
Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren zur Hörgeräteanpassung anzugeben, das die horizontale Richtungshörfähigkeit, insbesondere unter Freifeldbedingungen, berücksichtigt und so eine Optimierung der Hörgeräteeinstellung ermöglicht. Diese Aufgabe wird mit einem Verfahren zur Hörgeräteanpassung mit den Merkmalen des Anspruchs 1 gelöst. Unteransprüche sind auf bevorzugte Ausgestaltungen gerichtet.It is the object of the present invention to specify a method for adapting the hearing device, which takes into account the horizontal directional hearing, in particular under free-field conditions, and thus enables an optimization of the hearing device setting. This object is achieved with a method for hearing aid fitting with the features of
Ein erfindungsgemäßes Verfahren zur Hörgeräteanpassung ist gekennzeichnet durch einen Anpassschritt zur Berücksichtigung der Richtungshörfähigkeit in der horizontalen Ebene. Dieser Schritt wird im Rahmen einer Hörgeräteanpassungsprozedur durchgeführt, die ansonsten die an sich bekannten Hörgeräteanpassungsschritte umfassen kann.An inventive hearing aid adaptation method is characterized by a fitting step for taking into account the directional hearing in the horizontal plane. This step is performed as part of a hearing aid fitting procedure that may otherwise include the conventional hearing aid adjustment steps.
Der erfindungsgemäße Anpassschritt umfasst die Erzeugung von horizontal räumlichen Klangbildern, die Schallsignalen aus unterschiedlichen horizontalen Soll-Richtungen entsprechen. Die in der horizontalen Ebene räumlichen Klangbilder werden dem Probanden, also insbesondere einem Hörgerätenutzer, zum Beispiel im mit Hörgeräten versorgten Zustand zur Angabe der subjektiv empfundenen horizontalen Richtung dargeboten, aus der der Schall zu kommen scheint. Der Hörgerätenutzer gibt also diejenige horizontale Richtung an, aus der er den Schall wahrzunehmen meint.The adaptation step according to the invention comprises the generation of horizontally spatial sound images which correspond to sound signals from different horizontal desired directions. The sound patterns spatial in the horizontal plane become the subject, in particular one Hearing aid users, for example, in the state supplied with hearing aids for indicating the subjectively perceived horizontal direction presented, from which the sound seems to come. The hearing aid user thus specifies the horizontal direction from which he thinks he perceives the sound.
Die auf diese Weise angegebene jeweilige subjektive horizontale Hörrichtung wird mit der entsprechenden Soll-Richtung verglichen. In Abhängigkeit dieses Vergleichs werden zu verändernde Hörgeräteverstärkungsfaktoren bestimmt. Vorzugweise werden Verstärkungsfaktoren beider Hörgeräte in Abhängigkeit des Vergleichsergebnisses gewählt, wobei die jeweiligen Verstärkungsfaktoren zusätzlich frequenz- und pegelabhängig gewählt werden können.The respective subjective horizontal hearing direction indicated in this way is compared with the corresponding desired direction. Depending on this comparison, hearing aid amplification factors to be changed are determined. Preferably, amplification factors of both hearing aids are selected as a function of the comparison result, wherein the respective amplification factors can additionally be selected frequency-dependent and level-dependent.
Das Verfahren ermöglicht also bei der beidseitigen Anpassung die Überprüfung und Korrektur des Richtungshörens in der Horizontalebene. Besonders vorteilhaft ist dabei, dass die Richtungshörbestimmung in der horizontalen Ebene unter Freifeldbedingungen, d.h. unter Anwendungsbedingungen von Hörgeräten, durchgeführt werden kann und Optimierungsinformationen abgeleitet werden können.Thus, in the case of the two-sided adaptation, the method makes it possible to check and correct the directional hearing in the horizontal plane. It is particularly advantageous that the directional hearing determination in the horizontal plane under free field conditions, i. under conditions of use of hearing aids, and optimization information can be derived.
Besonders vorteilhaft ist es, wenn für die horizontal räumlichen Klangbilder geeignete natürliche Klangbilder eingesetzt werden, die insbesondere ausgewählten Lebenssituationen entsprechen. Das stellt sicher, dass keine Verfälschung des Anpassungsergebnisses aufgrund von für den Probanden ungewöhnlichen Geräuschsituationen vorkommen kann.It is particularly advantageous if suitable natural sound images are used for the horizontal spatial sound images, which in particular correspond to selected life situations. This ensures that no falsification of the adaptation result due to unusual for the subject noise situations may occur.
Störgeräusche weisen meist ein breitbandiges Spektrum ohne auffallende tonale Komponenten auf und haben in der Regel eine gleichmäßige Zeitstruktur. In Anbetracht dessen erweist es sich als besonders vorteilhaft, wenn die Signalstruktur der Klangbilder, die dem Probanden bei dem erfindungsgemäßen Verfahren dargeboten werden, möglichst singuläre tonale Komponenten im hörbaren Frequenzbereich aufweisen. Außerdem ist es vorteilhaft, wenn kurzzeitige Signalstrukturen gewählt werden, bevorzugt kürzer als 20 s, besonders bevorzugt kürzer als 10 s.Noise usually has a broadband spectrum without striking tonal components and usually has a uniform time structure. In view of this, it proves to be particularly advantageous if the signal structure of the sound images which are presented to the test person in the method according to the invention have as far as possible singular tonal components in the audible frequency range. Moreover, it is advantageous if short-term signal structures are selected, preferably shorter than 20 s, particularly preferably shorter than 10 s.
Beispiele für derartige natürliche Klangbilder aus dem normalen Lebensbereich sind z.B. das Zirpen von Grillen, ein Fön, eine Autohupe, ein Ampelton, ein Bohrer, eine Gitarre oder eine Flöte.Examples of such natural sound images from the normal area of life are e.g. the sound of crickets, a hair dryer, a car horn, a traffic light, a drill, a guitar or a flute.
Eine einfache Möglichkeit zur Erzeugung der horizontal räumlichen Klangbilder stellt eine Stereowiedergabeanordnung dar. Unterschiedliche horizontale Sollrichtungen können dabei beispielsweise durch eine positionsabhängige Dämpfung der beiden Stereokanäle erreicht werden.A simple possibility for generating the horizontal spatial sound images is a stereo display device. Different horizontal desired directions can be achieved for example by a position-dependent attenuation of the two stereo channels.
Es ist bevorzugt, wenn wenigstens ein Teil der dargebotenen räumlichen Klangbilder ohne Störgeräusche gewählt wird.It is preferable if at least a part of the presented spatial sound images is selected without noises.
Das erfindungsgemäße Verfahren kann eingesetzt werden, um eine Hörgeräteeinstellung zu optimieren. Dabei wird das Verfahren mit dem Hörgerätenutzer unter Verwendung von Hörgeräten durchgeführt, deren Einstellung mit Hilfe des erfindungsgemäßen Verfahrens optimal angepasst wird.
Dabei wird also die horizontale Richtungshörfähigkeit des Hörgerätenutzers unter Verwendung der Hörgeräte getestet.The method according to the invention can be used to optimize a hearing device setting. In this case, the method is carried out with the hearing device user using hearing aids, the setting of which is optimally adapted with the aid of the method according to the invention.
Thus, the horizontal directional hearing of the hearing device user is tested using the hearing aids.
Das erfindungsgemäße Verfahren kann auch im Vorfeld der Hörgeräteanpassung durchgeführt werden, indem es mit dem Hörgeschädigten ohne Hörgeräte durchgeführt wird. Aus einem Vergleich eines derartig ermittelten horizontalen Richtungshörens mit den Ergebnissen bei einem versorgten Zustand können dann Verbesserungen der Richtungshörfähigkeit dokumentiert werden. In einem weiteren Anwendungsfall kann ein Unterschied zwischen einer einseitigen und einer beidseitigen Hörgeräteversorgung dargestellt werden.The method according to the invention can also be carried out in advance of the hearing device adaptation by performing it with the hearing impaired without hearing aids. From a comparison of such a determined horizontal direction hearing with the results in a supplied state can then improve the direction hearing be documented. In another application, a difference between a one-sided and a two-sided hearing aid supply can be displayed.
Das erfindungsgemäße Verfahren kann Teil eines Hörgeräteanpassungsprozesses sein, in dem auch andere individuelle Hörfehler des Hörgeschädigten berücksichtigt werden.The method according to the invention can be part of a hearing aid adaptation process in which other individual hearing defects of the hearing impaired person are also taken into account.
Unabhängig von dem Hörgeräteanpassungsverfahren können der in diesem Zusammenhang beschriebene erfindungsgemäße Richtungshörtest in der Horizontalebene und die geschilderten besonderen Ausgestaltungen auch allgemein im Rahmen eines Richtungshörtests in der Horizontalebene eingesetzt werden, der nicht notwendigerweise bei einer Hörgeräteanpassung verwendet wird.Regardless of the hearing aid fitting method, the directional hearing test in the horizontal plane described herein and the particular embodiments described may also be generally used in a horizontal listening directional listening test that is not necessarily used in a hearing aid fitting.
Eine Vorrichtung zur Durchführung eines Richtungshörtests in der Horizontalebene, wie es in einem erfindungsgemäßen Verfahren zur Hörgeräteanpassung eingesetzt werden kann, weist zum Beispiel eine Einrichtung zur Wiedergabe von in einer horizontalen Ebene räumlichen, vorzugsweise natürlichen Klangbildern auf, die Schallsignalen aus unterschiedlichen horizontalen Soll-Richtungen entsprechen. Eine Eingabevorrichtung ist vorgesehen, mit deren Hilfe die subjektive horizontale Richtung, aus der der Schall zu kommen scheint, eingegeben werden kann. Eine Auswerteeinrichtung dient der Angabe und/oder dem Vergleich der eingegebenen subjektiven horizontalen Richtungen und der korrespondierenden Soll-Richtungen.A device for carrying out a directional hearing test in the horizontal plane, as may be used in a hearing aid fitting method according to the invention, has, for example, a device for reproducing spatial, preferably natural, sound images in a horizontal plane which correspond to sound signals from different horizontal desired directions , An input device is provided, by means of which the subjective horizontal direction from which the sound appears to come can be entered. An evaluation device serves to specify and / or compare the input subjective horizontal directions and the corresponding desired directions.

The adjustment can be carried out in this way so long in alternation with the directional hearing test until the horizontal direction hearing of the hearing device user is optimized when using the hearing aid and the directional hearing in the horizontal plane of a normal hearing as well as possible.
