Abstract
Description
Die Erfindung betrifft ein im Ohr tragbares Hörhilfegerät oder Hörhilfegerät mit im Ohr tragbarer Otoplastik mit einem Belüftungskanal.The invention relates to a hearing aid that can be worn in the ear or Hearing aid with earmold that can be worn in the ear with a Ventilation duct.
Der Belüftungskanal, auch als Ventilationsbohrung oder kurz Vent bezeichnet, eines im Ohr tragbaren Hörhilfegeräts oder eines Hörhilfegeräts mit im Ohr tragbarer Otoplastik dient der Belüftung des Ohrkanals, dem atmosphärischen Druckausgleich oder zur Verringerung des Verschlusseffekts (Okklusionseffekt). Dafür ist ein möglichst großer Querschnitt des Belüftungskanals wünschenswert. Andererseits stellt er einen akustischen Bypass zum Signalpfad über den Eingangswandler, die Signalverarbeitungseinheit und den Ausgangswandler des Hörhilfegeräts dar, was insbesondere in einer lauten Schallsituation dazu führen kann, dass Funktionen des Hörhilfegeräts wie eine besondere Richtwirkung oder eine Störgeräuschminderung unwirksam werden. Darüber hinaus kommt es vor allem in Schallsituationen mit einem niedrigen Pegel des Eingangssignals und einer durch die Dynamikkompression bedingten hohen Verstärkung des Hörhilfegeräts über den Belüftungskanal zu Rückkopplungen zwischen dem Ausgangswandler und dem Eingangswandler. Auch dieser Effekt ist abhängig vom Querschnitt des Belüftungskanals. Aus den genannten Gründen resultiert die Forderung nach einem möglichst kleinen Querschnitt des Belüftungskanals. Die Weite des Belüftungskanals stellt somit einen Kompromiss zwischen Tragekomfort und Leistungsmerkmalen des Hörhilfegeräts dar. Sie wird in der Regel bei der Anpassung des Hörhilfegeräts durch Einsetzen von Hülsen mit unterschiedlichen Bohrungen zur Verengung des Belüftungskanals eingestellt. The ventilation duct, also as a ventilation hole or short Vent refers to a hearing aid worn in the ear or a hearing aid with earmold earmould the ventilation of the ear canal, the atmospheric pressure balance or to reduce the closure effect (occlusion effect). For this is the largest possible cross section of Ventilation ducts desirable. On the other hand, he introduces one acoustic bypass to the signal path via the input transducer, the signal processing unit and the output transducer of Hearing aid, which is especially in a loud sound situation can lead to features of the hearing aid such as a special directivity or a noise reduction become ineffective. In addition, it comes first and foremost in sound situations with a low level of the input signal and a high due to the dynamic compression Reinforcement of the hearing aid via the ventilation duct to feedbacks between the output transducer and the input transducer. This effect also depends on the cross section of the ventilation duct. For the reasons mentioned results the demand for the smallest possible cross section of Ventilation duct. The width of the ventilation channel thus provides a compromise between comfort and performance It is usually used when adjusting the hearing aid of the hearing aid by inserting sleeves with different Holes for narrowing the ventilation channel set.
Aus der US 6,339,648 B1 ist ein in einen Gehörgang einsetzbares Teil bekannt. Dieses Teil kann als Otoplastik in Verbindung mit einem hinter dem Ohr tragbaren Hörgerät, als Gehörschutzgerät oder als in dem Ohr tragbares Hörgerät ausgebildet sein. Durch einen ersten Kanal kann das Teil befüllt werden, so dass sich die äußere Form des Teils individuell an den jeweiligen Gehörgang anpasst. Weiterhin ist ein Belüftungskanal mit über seinen gesamten Verlauf gleichbleibender Querschnittsfläche vorhanden. Darüber hinaus ist ein Akustik-Kanal vorhanden, der an einem Ende aufgeweitet ist und dadurch bei der Ausführung des Teils als Gehörschutzgerät einen Stöpsel und bei der Ausführung des Teils als Otoplastik einen Schallschlauch aufnehmen kann.From US 6,339,648 B1 can be inserted into an ear canal Part known. This part can be used as earmold with a hearing aid worn behind the ear, as a hearing protection device or as a hearing aid worn in the ear be. Through a first channel, the part can be filled so that the outer shape of the part is personalized adjusts the respective auditory canal. Furthermore, there is a ventilation duct with consistent over its entire course Cross-sectional area available. In addition, there is an acoustic channel present, which is widened at one end and thereby in the execution of the part as a hearing protection device Plug and in the execution of the part as earmold one Sound tube can record.
Aus der DE 90 10 540 U1 ist eine Otoplastik mit einem Belüftungskanal bekannt. In eine am distalen Ende der Otoplastik vorgesehene Erweiterung des Belüftungskanals ist ein Sperrmittel eingesetzt. Dieses ist als drehbar gelagertes, zylindrisches Teil mit einer exzentrischen Öffnung ausgebildet, wobei der Durchmesser der Öffnung dem Durchmesser des Belüftungskanals entspricht. Durch Drehen des zylindrischen Teils kann die Öffnung des Belüftungskanals verkleinert bzw. vollständig geschlossen werden.From DE 90 10 540 U1 is an earmold with a ventilation duct known. In one at the distal end of the earmold intended extension of the ventilation duct is a blocking means used. This is as a rotatably mounted, cylindrical Part formed with an eccentric opening, wherein the diameter of the opening is the diameter of the ventilation duct equivalent. By turning the cylindrical part can the opening of the ventilation duct reduced or completely getting closed.
Aufgabe der vorliegenden Erfindung ist es, den Belüftungskanal bei einem im Ohr tragbaren Hörhilfegerät oder einem Hörhilfegerät mit im Ohr tragbarer Otoplastik so weiterzubilden, dass eine gute Ventilationswirkung erreicht wird und gleichzeitig die Gefahr von Rückkopplungen durch den Beluftungskanal minimiert wird.Object of the present invention is the ventilation duct in a hearing aid worn in the ear or a hearing aid so educate with earmold earmould that a good ventilation effect is achieved and at the same time the risk of feedback through the ventilation duct is minimized.
Diese Aufgabe wird für ein im Ohr tragbares Hörhilfegerät oder Hörhilfegerät mit im Ohr tragbarer Otoplastik mit einem Belüftungskanal dadurch gelost, dass der Beluftungskanal in wenigstens einen ersten und einen zweiten Teilbereich unterteilt ist, wobei der bei getragenem Hörhilfegerät oder getragener Otoplastik proximale erste Teilbereich eine erste Querschnittsfläche und eine erste Länge aufweist und der distale zweite Teilbereich eine kleinere Länge und eine größere Querschnittsfläche im Vergleich zu dem ersten Teilbereich aufweist aufweist und wobei das distale Ende des zweiten Teilbereichs die distale Ventilationsöffnung des Belüftungskanals bildet.This task is for a hearing aid that can be worn in the ear or Hearing aid with earmold that can be worn in the ear with a Ventilation channel solved by the fact that the ventilation channel in subdivided at least a first and a second subarea is worn with the worn hearing aid or worn Otoplasty proximal first portion of a first cross-sectional area and a first length and the distal one second portion a smaller length and a larger cross-sectional area compared to the first subarea and wherein the distal end of the second portion the distal ventilation opening of the ventilation duct forms.
In einer Modellvorstellung kann der Belüftungskanal in erster Näherung durch eine Übertragung des Schalldrucks über eine Masse dargestellt werden. Der Ausgang des Belüftungskanals, die sog. Ventilationsöffnung, strahlt ein Schallsignal in den freien Raum ab, was wiederum über eine bewegte Mediumsmasse beschrieben werden kann. Diese massenbehaftete Aufteilung des anliegenden Schalldrucks ist näherungsweise frequenzunabhängig und sorgt für eine starke Abstrahlung aus der Ventilationsöffnung.In a model presentation, the ventilation duct in the first Approximation by a transmission of the sound pressure over a Mass be presented. The outlet of the ventilation duct, the so-called ventilation opening, emits a sound signal in the free space, which in turn via a moving medium mass can be described. This massed division of the adjacent sound pressure is approximately frequency independent and ensures a strong radiation from the ventilation opening.
Ausgehend von dieser Modellvorstellung kann über eine gezielte Veränderung des Ventilationskanals die entscheidende bewegte Mediumsmasse der Ventilationsöffnung reduziert werden. Dabei wirkt durch einen veränderten Querschnitt am Ende des Belüftungskanals bei ansonsten unverändertem Belüftungskanal eine verringerte Strahlungsimpedanz. Der Vorteil gegenüber den herkömmlichen Ventilationssystemen besteht in der vermindernden akustischen Abstrahlung in den Raum. Dies ergibt eine deutlich verbesserte Stabilität der Hörgeräte in der Praxis und erlaubt zum anderen die Verwendung eines Belüftungskanals mit gegenüber einem herkömmlichen Hörhilfegerät bzw. einer herkömmlichen Otoplastik in allen Teilbereichen vergrößerten Querschnittsfläche unter Beibehaltung der Stabilitätsbedingungen.Starting from this model concept can be over a purposeful Change of ventilation channel the decisive moved Medium mass of the ventilation opening can be reduced. It acts by a modified cross section at the end of Ventilation duct with otherwise unchanged ventilation duct a reduced radiation impedance. The advantage over The conventional ventilation systems consists in diminishing acoustic radiation in the room. This gives a significantly improved stability of hearing aids in practice and on the other hand allows the use of a ventilation duct with respect to a conventional hearing aid or a enlarged conventional earmold in all areas Cross-sectional area while maintaining the stability conditions.
Vorteilhaft ist der bei getragenem Hörhilfegerät oder getragener Otoplastik proximale Teilbereich des Belüftungskanals gemäß der Erfindung wesentlich länger als der distale Teilbereich mit der vergrößerten Querschnittsfläche. So wird erreicht, dass der Strömungswiderstand des Belüftungskanals im Wesentlichen unverändert bleibt. In der Praxis hat sich gezeigt, dass die Länge des ersten Teilbereiches wenigstens die fünffache Länge des zweiten Teilbereiches aufweisen sollte.It is advantageous when worn hearing aid or worn Otoplasty proximal portion of the ventilation duct much longer than the distal portion according to the invention with the enlarged cross-sectional area. This is how it is achieved that the flow resistance of the ventilation duct in Essentially unchanged. In practice it has been shown that the length of the first portion at least the should have five times the length of the second portion.
Bezüglich der Größenverhältnisse der Querschnittsflächen konnte festgestellt werden, dass die Querschnittsfläche des zweiten Teilbereiches vorteilhaft wenigstens die dreifache Querschnittsfläche des ersten Teilbereiches aufweist, womit eine wesentliche Reduzierung der Abstrahlung der von der Ventilationsöffnung abgestrahlten Schallanteile erreicht wird. Regarding the size ratios of the cross-sectional areas could be determined that the cross sectional area of the second portion advantageously at least three times Has cross-sectional area of the first portion, which a substantial reduction of radiation from the ventilation opening radiated sound components is achieved.
Eine Ausführungsform der Erfindung sieht vor, dass insbesondere bei längeren Belüftungskanälen akustische Filterelemente in einem Belüftungskanal angeordnet sind. Längere Belüftungskanäle bewirken nämlich das Auftreten von Leitungsresonanzen, an denen die akustische Leitfähigkeit des Belüftungskanals maximiert wird. Durch die akustischen Filterelemente wird das Auftreten von Resonanzeffekten verhindert. Die Filterelemente können beispielsweise als Querschnittssprünge oder als in den Belüftungskanal eingebrachte akustische Dämpfungselemente ausgebildet sein.An embodiment of the invention provides, in particular for longer ventilation channels acoustic filter elements are arranged in a ventilation duct. Longer ventilation channels cause the occurrence of conduction resonances, where the acoustic conductivity of the ventilation duct is maximized. By the acoustic filter elements is the Occurrence of resonance effects prevented. The filter elements For example, as cross-sectional jumps or than in the Ventilation duct introduced acoustic damping elements be educated.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels
näher beschrieben. Dabei zeigen:
In Figur 1 ist in schematischer, stark vereinfachter Darstellung
ein in dem Gehörgang 1 eines Hörgeräteträgers angeordnetes
Hörhilfegerät 2 dargestellt. Ein akustisches Signal wird
dem Ohr des Hörgeräteträgers einerseits über ein Mikrofon 8,
eine Signalverarbeitungseinheit (nicht dargestellt) und einen
Hörer 3 mit zugeordnetem Hörerkanal 4 und andererseits über
den Belüftungskanal 5 zugeführt. Der Belüftungskanal 5 stellt
somit einen Bypass zum elektroakustischen Signalpfad durch
das Hörhilfegerät 2 dar. In bestimmten akustischen Situationen,
z.B. bei geringer akustischer Verstärkung des Hörhilfegeräts
aufgrund einer lauten Schallumgebung, ist dieser Bypass
gegenüber dem Signalpfad durch das Hörhilfegerät dominierend.
Dies kann dazu führen, dass bestimmte Funktionen des
Hörhilfegeräts, wie z.B. eine gewünschte Richtwirkung oder
eine Störgeräuschminderung, nurmehr eingeschränkt ausgeführt
werden können. Darüber hinaus kann es durch den Belüftungskanal
5 auch zu Rückkopplungen zwischen dem Hörer 3 und dem
Mikrofon 8 kommen. Die von dem Mikrofon 8 aufgenommenen und
in elektrische Signale umgewandelten akustischen Eingangssignale
werden durch die Signalverarbeitungseinheit geleitet und
anschließend einem Hörer 3 zugeführt. Dieser strahlt wiederum
über den Hörerkanal 4 akustische Signale in den Ohrkanal 1
ab. Über die proximale Ventilationsöffnung 7 und den Belüftungskanal
5 gelangen diese akustischen Signale teilweise
wieder in den Außenraum und erreichen nach der Abstrahlung
von der distalen Ventilationsöffnung 6 das Mikrofon 8. Der
Rückkopplungspfad ist so geschlossen. Daher sollte der Belüftungskanal
5 lediglich eine verhältnismäßig kleine Querschnittsfläche
aufweisen. Dies verschlechtert jedoch die Belüftung
des durch das Hörhilfegerät 2 abgeschlossenen Teils
des Ohrkanals 1.In Figure 1 is a schematic, highly simplified representation
a arranged in the ear canal 1 of a hearing aid
Figur 2 zeigt ebenfalls ein im Ohr tragbares Hörhilfegerät 2,
das sich in dem Ohrkanal 1 eines Hörgeräteträgers befindet.
Hierbei ist jedoch der Belüftungskanal gemäß der Erfindung
dahingehend abgewandelt, dass ein dem Kopf abgewandter zweiter
Teilbereich 5B des Belüftungskanals gegenüber einem ersten,
dem Kopf zugewandten Teilbereich 5A aufgeweitet ist, womit
der zweite Teilbereich 5B eine gegenüber dem ersten Teilbereich
5A vergrößerte Querschnittsfläche aufweist. Die Längenverhältnisse
der Teilbereiche sind dabei vorzugsweise so
bemessen, dass der Teilbereich 5A wesentlich länger als der
Teilbereich 5B ist. Dadurch ist gewährleistet, dass der Strömungswiderstand
des Belüftungskanals im Wesentlichen dem
Strömungswiderstand des Teilbereiches 5A entspricht. Durch
die Veränderung des Belüftungskanals im Bereich der distalen
Ventilationsöffnung 6 wird erreicht, dass die entscheidende
bewegte Mediumsmasse dieser Ventilationsöffnung 6 reduziert
ist. Durch den veränderten Querschnitt an dem dem Kopf abgewandten
Ende des Belüftungskanals wird bei ansonsten unverändertem
Kanal eine verringerte Strahlungsimpedanz erreicht.
Dies bewirkt, dass der Schalldruck des über den Hörer 3 abgegebenen
und über den Hörerkanal 4 und den Belüftungskanal 5A,
5B wieder zum Mikrofon 8 gelangenden Signals gegenüber dem
Schalldruck eines vergleichbaren Signals bei einem Horhilfegerät
mit einem herkömmlichen Belüftungskanal reduziert ist.
Die Rückkopplungsneigung des Hörhilfegeräts ist dadurch vermindert.
Insgesamt kann dadurch die Bandbreite der durch das
Hörhilfegerät 2 gemäß der Erfindung übertragbaren akustischen
Signale in Richtung höherer Frequenzen erweitert werden. Weiterhin
kann der gesamte Querschnitt des Belüftungskanals gegenüber
dem Querschnitt eines Belüftungskanals bei einem herkömmlichen
Hörhilfegerät erweitert werden, ohne dass hierbei
die Rückkopplungsneigung des Hörhilfegerätes zunimmt.FIG. 2 likewise shows a
Als weitere Möglichkeit zur Verringerung des Anteils der akustischen
Energie, die über den Belüftungskanal in die freie
Umgebung abgestrahlt und von dem Mikrofon erneut aufgenommen
werden kann, ist bei dem Hörhilfegerät 2 gemäß Figur 2 ein
akustischer Dämpfer in dem Belüftungskanal vorhanden. Dadurch
wird das Auftreten von Resonanzeffekten in dem Belüftungskanal
verhindert.As another way to reduce the percentage of acoustic
Energy flowing through the ventilation duct into the free
Surround sounded and recorded by the microphone again
can be in the
