It is not necessarily the units that provide the sound signals S1 and S2, are set, but it can also other components with the adjustment signals E1 and E2 of the respective hearing aid 10, 11 are set.
- the hearing aid system consists of two hearing aids 20 and 21.
- the first hearing aid 20 has a first modeling device 22, in which a perceptive model for monaural hearing is implemented.
- a first sound signal S1 originating from a microphone or any other signal processing unit of the first hearing device 20 is recorded in order to generate a first psychoacoustic variable P1.
- a second sound signal S2 which originates from a local microphone or a local signal processing unit, recorded by a modeling device 23 and processed to a second psychoacoustic size P2.
- a perceptive model for binaural hearing is implemented.
- the latter generates on the basis of the two psychoacoustic signals P1 and P2 two setting signals E1 and E2 for signal processing components 25 and 26 of the two hearing aids 20, 21.
- a binaural perceptive model is used here to combine the monaural model statements into a single statement or to change one of the two sides so that an optimal sound impression, an optimal speech understanding and / or an optimal localization effect etc. is achieved.
- parameters of both hearing aids of a hearing system can optionally be changed symmetrically on the basis of a binaural decision matrix in order to obtain a symmetrical hearing impression overall.
- the symmetrical activation or deactivation of other adaptive parameters such as noise removal or directional microphone is possible.
- the aim is also to offer a symmetrical hearing impression for the hearing aid wearer.
- the two adjustment signals E1 and E2 may be different, for example, if they affect the gain and the hearing impaired has different deficits in both ears. However, when it comes to enabling or disabling noise removal or a directional microphone, the two setting signals E1 and E2 should be the same. Thus, the two hearing aids can be synchronized on the basis of the perceptual model for binaural perception and it can be achieved a symmetrical listening experience.

Im Fall einer binauralen Anpassung können die Parameter für das linke und das rechte Gerät unterschiedlich sein. Mögliche Ursachen hierfür können deutlich unterschiedliche Signale rechts und links, oder aber unterschiedliche Hörverluste auf beiden Seiten sein. Die daraus resultierenden Modifikationen an der Konfiguration des Hörsystems können dann ebenfalls binaural unterschiedlich sein, so dass möglicherweise ein seitendifferenter Höreindruck entsteht. Dies ist insbesondere für Algorithmen wie Störgeräuschbefreiung und Richtmikrofonie unpraktikabel.In the case of a binaural adaptation, the parameters for the left and right devices may be different. Possible causes for this can be clearly different signals on the right and left or different hearing losses on both sides. The resulting modifications to the configuration of the hearing system can then also be binaurally different, so that possibly produces a side-by-side auditory impression. This is impractical in particular for algorithms such as noise removal and directional microphones.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein Verfahren bereitzustellen, mit dem das Einstellen eines Hörsystems zur binauralen Versorgung besser und individueller erfolgen kann. Außerdem soll ein entsprechendes Hörsystem bereitgestellt werden.The object of the present invention is therefore to provide a method with which the setting of a hearing system for binaural care can be better and more individualized. In addition, a corresponding hearing system is to be provided.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Verfahren zum Einstellen eines Hörsystems mit einem linken Gerät und einem rechten Gerät zur binauralen Versorgung eines Nutzers, durch Bereitstellen eines elektrischen Schallsignals zur Versorgung des linken Ohrs des Nutzers und Bereitstellen eines elektrischen Schallsignals zur Versorgung des rechten Ohrs des Nutzers, sowie Ermitteln auf der Grundlage der beiden Schallsignale eines linken Einstellwerts für das linke Gerät und eines rechten Einstellwerts für das rechte Gerät durch ein perzeptives Modell für binaurales Hören und Einstellen des linken Geräts mit dem linken Einstellwert sowie des rechten Geräts mit dem rechten Einstellwert.According to the invention, this object is achieved by a method for adjusting a hearing system with a left-hand device and a right-hand device for binaurally supplying a user, by providing an electrical sound signal for supplying the user's left ear and providing an electrical sound signal for supplying the user's right ear and determining based on the two sound signals of a left set value for the left apparatus and a right set value for the right apparatus through a perceptual model for binaural listening and setting the left apparatus with the left set value and the right apparatus with the right set value.
Ferner wird erfindungsgemäß bereitgestellt ein Hörsystem mit einem linken Gerät, das ein elektrisches Schallsignal zur Versorgung des linken Ohrs des Nutzers liefert, und einem rechten Gerät, das ein elektrisches Schallsignal zur Versorgung des rechten Ohrs des Nutzers liefert, wobei mindestens in einem der beiden Geräte oder einem weiteren zum Hörsystem gehörenden Gerät ein perzeptives Modell für binaurales Hören implementiert ist, mit dem auf der Grundlage der beiden Schallsignale ein linker Einstellwert für das linke Gerät und/oder ein rechter Einstellwert für das rechte Gerät ermittelbar ist, und das linke Gerät mit dem linken Einstellwert und/oder das rechte Gerät mit dem rechten Einstellwert einstellbar sind/ist.Further provided according to the invention is a hearing system with a left-hand device, which supplies an electrical sound signal for the supply of the left ear of the user, and a right-hand device, which supplies an electrical sound signal for the supply of the right ear of the user, wherein at least one of the two devices or another device belonging to the hearing system is a perceptive model for binaural hearing is implemented, with the basis of the two sound signals, a left set value for the left device and / or a right set value for the right device can be determined, and the left device with the left set value and / or the right device with the right set value adjustable are / is.
In vorteilhafter Weise ist es so möglich, die binaurale Wahrnehmung von Schallen bei der automatischen Steuerung eines Hörsystems zu berücksichtigen. Hierdurch lässt sich die Akzeptanz von Hörsystemen bei binauraler Versorgung deutlich verbessern.Advantageously, it is thus possible to take into account the binaural perception of sounds in the automatic control of a hearing system. As a result, the acceptance of hearing systems in binaural care can be significantly improved.
Vorzugsweise sind die beiden Einstellwerte für das linke Gerät und das rechte Gerät gleich. Auf diese Weise lässt sich ein symmetrischer Höreindruck erzielen.Preferably, the two settings for the left and right devices are the same. In this way, a symmetrical listening experience can be achieved.
Insbesondere können die beiden Einstellwerte das Aktivieren oder Deaktivieren einer Störgeräuschbefreiungsfunktion und/oder einer Richtmikrofonfunktion beider Geräte veranlassen. Damit werden Funktionen, die den binauralen Höreindruck wesentlich beeinflussen, auf der Grundlage von psychoakustischen Modellwerten gesteuert.In particular, the two setting values may cause the activation or deactivation of a noise removal function and / or a directional microphone function of both devices. Thus, functions that significantly influence the binaural hearing impression are controlled on the basis of psychoacoustic model values.
Darüber hinaus können beim Ermitteln der Einstellwerte durch das perzeptive Modell der Klangeindruck, das Sprachverstehen und/oder die Lokalisationswirkung als maßgebliche psychoakustische Größe dienen. Es können aber auch andere psychoakustische Größen wie Schärfe, Rauhigkeit, Höranstrengung, etc. herangezogen werden.In addition, when determining the setting values by the perceptual model, the sound impression, the speech understanding, and / or the localization effect may serve as the authoritative psychoacoustic quantity. However, other psychoacoustic parameters such as sharpness, roughness, hearing effort, etc. can also be used.
Entsprechend einer besonderen Ausführungsform erhält das perzeptive Modell für binaurales Hören jeweils eine psychoakustische Größe von einem perzeptiven Modell für monaurale Wahrnehmung von jedem der beiden Geräte zur Ermittlung der Einstellwerte. Auf diese Weise ist es möglich, den Rechenaufwand für ein perzeptives Modell für binaurales Hören auf zwei Hörgeräte zu verteilen.According to a particular embodiment, the perceptual model for binaural hearing each obtains a psychoacoustic size from a perceptual model for monaural perception of each of the two devices for determining the set values. In this way it is possible to reduce the computational effort for a perceptive model for binaural hearing to distribute on two hearing aids.

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.
In
Das erste Hörgerät 10 besitzt eine Signalverarbeitungseinheit 12, die ein elektrisches Schallsignal S1 an eine Modelliereinrichtung 13 liefert, in der ein perzeptives Modell für binaurales Hören implementiert ist. Dieses perzeptive Modell für binaurales Hören liefert eine Aussage insbesondere darüber, welchen Höreindruck der Schwerhörende von einem Schall hat, den er über beide Ohren wahrnimmt. Die binaurale Wahrnehmung unterscheidet sich nämlich durchaus von der monauralen Wahrnehmung, denn ein Schall wird beispielsweise beim Hören mit beiden Ohren lauter wahrgenommen als beim Hören mit nur einem Ohr. Auch können in dem perzeptiven Modell für binaurales Hören psychoakustische Größen über Wahrnehmungen gewonnen werden, die nur mit zwei Ohren möglich sind, wie beispielsweise Lokalisationswirkung.The
Die Signalverarbeitungseinheit 12 kann ein Signalprozessor, ein einfaches Mikrofon oder jede andere Einheit sein, die ein elektrisches Signal basierend auf einem Eingangsschall liefert. Auch das zweite Hörgerät 11 besitzt eine derartige Signalverarbeitungseinheit 14. Diese liefert hier drahtlos über eine entsprechende Kommunikationseinrichtung ein zweites Schallsignal S2 an das erste Hörgerät 10, damit es von der Modelliereinrichtung 13 verarbeitet werden kann. Diese liefert nun auf der Basis der beiden Schallsignale S1 und S2 zwei Einstellsignale E1 und E2. Das linke bzw. erste Einstellsignal E1 ist für die hörgeräteinterne Signalverarbeitungseinheit 12 bestimmt. Das rechte bzw. zweite Einstellsignal E2 wird zu dem zweiten Hörgerät 11 übertragen und dort der Signalverarbeitungseinheit 14 zugeführt. Die Einstellwerte E1 und E2 werden auf der Grundlage von psychoakustischen Wahrnehmungsgrößen für binaurales Hören ermittelt und dienen nun zur Einstellung von Komponenten der beiden Geräte des Hörsystems. Dabei müssen nicht zwangsläufig diejenigen Einheiten, die die Schallsignale S1 und S2 liefern, eingestellt werden, sondern es können auch andere Komponenten mit den Einstellsignalen E1 und E2 des jeweiligen Hörgeräts 10, 11 eingestellt werden.The
Eine alternative Ausführungsform ist in
Mit Hilfe des gemeinsamen perzeptiven Modells für binaurales Hören können gegebenenfalls auf der Basis einer binauralen Entscheidungsmatrix Parameter beider Hörgeräte eines Hörsystems symmetrisch verändert werden, um insgesamt einen symmetrischen Höreindruck zu erhalten. Darüber hinaus ist die symmetrische Aktivierung bzw. Deaktivierung weiterer adaptiver Parameter wie einer Störgeräuschbefreiung oder eines Richtmikrofons möglich. Dabei wird ebenfalls das Ziel verfolgt, einen symmetrischen Höreindruck für den Hörsystemträger anzubieten.With the help of the common perceptive model for binaural hearing, parameters of both hearing aids of a hearing system can optionally be changed symmetrically on the basis of a binaural decision matrix in order to obtain a symmetrical hearing impression overall. In addition, the symmetrical activation or deactivation of other adaptive parameters such as noise removal or directional microphone is possible. The aim is also to offer a symmetrical hearing impression for the hearing aid wearer.
Die beiden Einstellsignale E1 und E2 können unterschiedlich sein, wenn sie beispielsweise die Verstärkung betreffen und der Schwerhörende an beiden Ohren unterschiedliche Defizite besitzt. Wenn es allerdings um das Aktivieren bzw. Deaktivieren der Störgeräuschbefreiung oder eines Richtmikrofons geht, sollten die beiden Einstellsignale E1 und E2 gleich sein. So lassen sich die beiden Hörgeräte auf der Grundlage des perzeptiven Modells für binaurale Wahrnehmung synchronisieren und es kann ein symmetrischer Höreindruck erzielt werden.The two adjustment signals E1 and E2 may be different, for example, if they affect the gain and the hearing impaired has different deficits in both ears. However, when it comes to enabling or disabling noise removal or a directional microphone, the two setting signals E1 and E2 should be the same. Thus, the two hearing aids can be synchronized on the basis of the perceptual model for binaural perception and it can be achieved a symmetrical listening experience.
Mit der vorliegenden Erfindung ist es folglich möglich, das gesamte Gehör bestehend aus einem linken und einem rechten Teil psychoakustisch auszuwerten und Einstellparameter für die einzelnen Geräte eines Hörsystems zu gewinnen.With the present invention, it is thus possible to psychoacoustically evaluate the entire hearing consisting of a left and a right part and to obtain setting parameters for the individual devices of a hearing system.
