HörgerätHearing aid
Die vorliegende Erfindung betrifft ein Hörgerät nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a hearing aid according to the preamble of patent claim 1.
Hörgeräte weisen eine Schalleintrittsoffnung zum Aufnehmen von Umgebungslauten und eine Schallaustrittsöffnung zur Abgabe der im Hörgerät verarbeiteten Umgebungslaute auf. Dabei ist es von grösster Bedeutung, dass denHearing aids have a sound entry opening for picking up ambient sounds and a sound exit opening for delivering the surrounding sounds processed in the hearing aid. It is of the utmost importance that the
Umgebungslauten in keiner Weise störende Geräusche überlagert werden, die in der Folge wie Umgebungslaute behandelt werden. Störende Geräusche können dabei die Ursache darin haben, dass Luftströmungen an Kanten am bzw. in der Nähe des Hörgerätes abreissen (Abriss-Problematik) oder dass Luftströmungen mit unterschiedlichen Geschwindigkeiten und/oder Richtungen im Bereich unmittelbar vor der Mikrophonmembran dazu führen, dass diese bewegt wird (Gradienten-Problematik) . Diese beiden genannten Ursachen können auch in Kombination auftreten.Surrounding noises are in no way superimposed on disturbing noises, which are subsequently treated as ambient noises. Disturbing noises can be caused by the fact that air currents at edges on or near the hearing aid break off (tear-off problem) or that air currents with different speeds and / or directions in the area immediately in front of the microphone membrane cause it to be moved (Gradient problem). These two causes can also occur in combination.
In der US-4 073 366 ist ein Deckelement beschrieben, das über die Schalleintrittsoffnung eines Hörgerätes geklebt wird. Das bekannte Deckelement besteht aus mehreren Schichten, die an den Rändern zusammengeklebt sind und die aus porösen Materialien bestehen, womit verhindert werden soll, dass an den Kanten der Eintrittsöffnung infolge von abreissenden Luftströmungen störende Geräusche entstehen.US Pat. No. 4,073,366 describes a cover element which is glued over the sound entry opening of a hearing aid. The known cover element consists of several layers which are glued together at the edges and which are made of porous materials, with the aim of preventing disturbing noises from occurring at the edges of the inlet opening as a result of tearing off air currents.
Es hat sich gezeigt, dass mittels dieser bekannten Lehre - 2 -It has been shown that by means of this known teaching - 2 -
die Störgeräusche insgesamt nur gering beeinflusst werden können, denn durch das Deckelement über derthe overall noise can be influenced only slightly, because of the cover element over the
Eintrittsöffnung kann zwar die Störgeräuschbildung aufgrund der Gradienten-Problematik reduziert werden, nicht jedoch die Störgeräusche, die aufgrund der Abriss-Problematik entstehen. Der Grund dafür liegt darin, dass durch das Anbringen von Deckelementen über der Schalleintrittsoffnung zur Verminderung von Strömungsabrissen an deren Kanten neue potentielle Herde von Störgeräuschen an den Kanten des Deckelementes selbst entstehen. Damit ist die Quelle für Störgeräusche lediglich verschoben worden.The opening noise can be reduced due to the gradient problem, but not the noise that occurs due to the demolition problem. The reason for this is that by attaching cover elements above the sound inlet opening to reduce flow stalls at their edges, new potential sources of noise are generated at the edges of the cover element itself. The source of noise has only been moved.
Der Vollständigkeit halber wird auf die Druckschrift EP-0 310 866 verwiesen, in der offenbart wird, dass die Schallaustrittsöffnung zur Verhinderung des Eintritts von Ohrenschmalz (Cerumen) in das Hörgerät mit einem Deckelement abzudecken, wobei die Verwendung eines mikroporösen Materials vorgeschlagen wird. Darüber hinaus kann dieser Druckschrift entnommen werden, dass die Schalleintritts ffnung dann mit einem Deckelement abgedeckt werden soll, sofern es sich um ein In-dem-Ohr-Hörgerät (IdO-Hörgerät) handelt, denn offensichtlich besteht nur dann eine Gefahr, dass Ohrenschmalz in das Hörgerät gelangt, wenn dieses im Ohr plaziert ist. Massnahmen zur Reduktion von störenden Geräuschen sind aus dieserFor the sake of completeness, reference is made to the document EP-0 310 866, in which it is disclosed that the sound outlet opening to prevent the entry of earwax (cerumen) into the hearing aid is covered with a cover element, the use of a microporous material being proposed. In addition, it can be seen from this document that the sound inlet opening is then to be covered with a cover element, provided that it is an in-the-ear hearing aid (ITE hearing aid), because there is obviously only a risk of ear wax in the hearing aid arrives when it is placed in the ear. Measures to reduce annoying noises are from this
Druckschrift nicht entnehmbar. Es handelt sich hier allein darum, die Verschmutzung von Hörgeräten zu vermeiden.Document cannot be removed. The sole purpose here is to avoid contamination of hearing aids.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Hörgerät anzugeben, bei dem die Störgeräuschbildung vermindert ist .The present invention is therefore based on the object of specifying a hearing aid in which the Noise is reduced.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Massnahmen gelöst . Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben .This object is achieved by the measures specified in the characterizing part of patent claim 1. Advantageous embodiments of the invention are specified in further claims.
Die Erfindung weist folgende Vorteile auf: Durch die Integration mindestens eines Deckelementes in das Hörgerät selbst und die oberflächenbündige Anordnung desThe invention has the following advantages: by integrating at least one cover element into the hearing aid itself and the surface-flush arrangement of the
Deckelementes im Hörgerätgehäuse werden Kanten vermieden, die ansonsten Quelle von Störgeräuschen sind, womit der Abriss-Problematik Rechnung getragen ist. Gleichzeitig wird aber auch der Gradienten-Problematik Rechnung getragen, indem das Deckelement aus einem porösen, vorzugsweise aus einem offenporösen Material gefertigt ist und eine gewisse Dicke aufweist.Cover element in the hearing aid housing edges are avoided, which are otherwise a source of noise, which takes into account the demolition problem. At the same time, however, the gradient problem is also taken into account by the cover element being made of a porous, preferably an open-porous material and having a certain thickness.
Es hat sich gezeigt, dass sich als Material für die Deckelemente ein offenporöses Polyäthylen besonders eignet. Die Eigenschaften des Materials können dabei einerseits durch die Filterfeinheit, die der minimalen Teilchengrösse der gefilterten Teilchen entspricht, und anderseits durch die Offenporigkeit , die dem Verhältnis zwischen Porenöffnung und Restfläche entspricht, charakterisiert werden. Die Filterfeinheit wird auch etwa mit d50-Werten angegeben, wobei beim angegebenen d50-Wert 50% der Partikel den Filter passieren und 50% der Partikel zurückbehalten werden. Es hat sich herausgestellt, dass die d50-Werte für die Filterfeinheit zwischen lOμm und 200μm und die Offenporigkeit zwischen 70 und nahezu 100% liegen.It has been shown that an open-pored polyethylene is particularly suitable as the material for the cover elements. The properties of the material can be characterized on the one hand by the filter fineness, which corresponds to the minimum particle size of the filtered particles, and on the other hand, by the open porosity, which corresponds to the ratio between the pore opening and the remaining area. The filter fineness is also given approximately with d50 values, with 50% of the particles passing through the filter at the specified d50 value and 50% of the particles being retained. It has been found that the d50 values for the filter fineness between lOμm and 200μm and the Open porosity is between 70 and almost 100%.
Durch die Verwendung eines homogenen Materials für die Deckelemente wird eine hohe Reproduzierbarkeit derselben erreicht, da keine Materialübergänge vorgesehen sind, welche die akustischen Eigenschaften des Gesamtsystems nachhaltig beeinflussen können, denn Materialübergänge beinhalten das Risiko, dass Abweichungen vom akustischen Normverhalten entstehen. Ferner ist sowohl die Fertigung als auch die Montage der erfindungsgemässen Deckelemente in Hörgeräten wesentlich einfacher und damit auch kostengünstiger .The use of a homogeneous material for the cover elements achieves a high level of reproducibility since there are no material transitions that can have a lasting effect on the acoustic properties of the overall system, because material transitions involve the risk that deviations from the acoustic standard behavior occur. Furthermore, both the manufacture and the assembly of the cover elements according to the invention in hearing aids is considerably simpler and therefore also more cost-effective.
Auf der anderen Seite besteht eine Ausführungsvariante der Erfindung darin, dass die aus einem homogenen Material gefertigten Deckelemente mit einer dünnen durchlässigen Schicht, beispielsweise Teflon, überzogen sind. Dies ergibt eine höhere Beständigkeit, was insbesondere bei äusseren chemischen Einflüssen von grosser Bedeutung ist . Darüber hinaus wird aber der Abriss-Problematik weiter Rechnung getragen, denn durch das Beschichten erhält das Deckelement eine feinere Oberfläche. Damit werden Abriss-Störgeräusche, die aufgrund von Unebenheiten in der Oberfläche der Deckelemente erzeugt werden, weiter vermindert.On the other hand, an embodiment variant of the invention consists in that the cover elements made of a homogeneous material are covered with a thin permeable layer, for example Teflon. This results in a higher resistance, which is particularly important in the case of external chemical influences. In addition, however, the demolition problem is taken into account, because the coating gives the cover element a finer surface. This further reduces tearing noise caused by unevenness in the surface of the cover elements.

Im Verstärkungselement VE wird im wesentlichen die elektronische Bearbeitung der akustischen Signale (siehe Pfeil ES) vorgenommen, die - nach der Verarbeitung - an das Hakenelement HE (siehe Pfeil SS) bzw. in einen darin enthaltenen Schallübertragungskanal UEK übergeben werden. Auf das Verstärkungselement VE des Hörgerätes ist an dieser Stelle nicht weiter einzugehen, da die Erfindung insbesondere auf die Ausstattung des Hakenelementes HE gerichtet ist.Reinforcing element VE connected, ie the hook element HE or the reinforcing element VE can be exchanged or replaced as desired. In the reinforcing element VE, essentially the electronic processing of the acoustic signals (see arrow ES) is carried out, which - after processing - is transferred to the hook element HE (see arrow SS) or into a sound transmission channel UEK contained therein. The reinforcing element VE of the hearing aid should not be discussed further at this point, since the invention is particularly directed to the equipment of the hook element HE.
Es wird jedoch ausdrücklich darauf hingewiesen, dass die Erfindung nicht auf Hörgeräte beschränkt ist, die aus zwei Teilen, nämlich Verstärkungselement VE und Hakenelement HE, bestehen. Vielmehr eignet sich die Erfindung insbesondere auch für Hörgeräte, die nur aus einem Gehäuseteil bestehen. Darüber hinaus kann die Erfindung sowohl bei IdO- (In-dem- Ohr) -Hörgeräten als auch bei HdO- (Hinter-dem-Ohr) - Hörgeräten angewendet werden.However, it is expressly pointed out that the invention is not limited to hearing aids which consist of two parts, namely reinforcing element VE and hook element HE. Rather, the invention is particularly suitable for hearing aids that consist of only one housing part. In addition, the invention can be used both in ITE (in-the-ear) hearing aids and in BTE (behind-the-ear) hearing aids.
Im Hinblick auf die vorliegende Erfindung ist die äussere Form des Verstärkungselementes VE von Bedeutung: Insbesondere im Übergangsbereich zwischen Verstärkungselement VE und Hakenelement HE - wiederum in bezug auf die Ausführungsform gemäss Fig. 1 - weisen diese identische - zumindest jedoch ähnliche - Konturen und Oberflächenbeschaffenheiten auf. Insgesamt weist das ganze erfindungsgemässe Hörgerät keine scharfen Kanten auf, damit keine störenden Geräusche erzeugt werden. - 7 -With regard to the present invention, the outer shape of the reinforcing element VE is important: in particular in the transition area between the reinforcing element VE and the hook element HE - again in relation to the embodiment according to FIG. 1 - they have identical - but at least similar - contours and surface properties. Overall, the entire hearing aid according to the invention has no sharp edges so that no disturbing noises are generated. - 7 -
Das Hakenelement HE enthält vorzugsweise keine elektronischen Komponenten, sondern ist insbesondere dazu da, Umgebungslaute möglichst störungsfrei aufzunehmen und - in Richtung Pfeil ES - in die Verstärkungseinheit VE zu übertragen. Anderseits werden die verarbeiteten akustischen Signale - in Richtung Pfeil SS - durch den Schallübertragungskanal UEK im Hakenelement HE zu einer Schallaustrittsöffnung SA übertragen, wo die akustischen Signale in den eigentlichen Gehörgang des Hörgeräteträgers gelangen.The hook element HE preferably does not contain any electronic components, but is there in particular to record ambient sounds as free of interference as possible and to transmit them in the direction of the arrow ES to the reinforcement unit VE. On the other hand, the processed acoustic signals - in the direction of arrow SS - are transmitted through the sound transmission channel UEK in the hook element HE to a sound exit opening SA, where the acoustic signals enter the actual auditory canal of the hearing aid wearer.
Erfindungsgemäss ist im Hakenelement HE ein Deckelement DE vorgesehen, der den Bereich der Schalleintrittsoffnung SE gegenüber der Aussenumgebung abdeckt, wobei das Deckelement DE in das Hakenelement HE derart integriert ist, dass keine Kanten an den Übergangsstellen zwischen dem Hakenelement HE und dem Deckelement DE vorhanden sind, d.h. das Deckelement DE ist oberflächenbündig in das Hakenelement HE integriert . Darüber hinaus ist das Deckelement DE gegen Aussen kugelförmig, zumindest aber kugelsektorförmig ausgebildet. Damit sind von Seiten Hörgerät keine Kanten vorhanden, die Quellen von Störgeräuschen sein können.According to the invention, a cover element DE is provided in the hook element HE, which covers the area of the sound entry opening SE from the outside environment, the cover element DE being integrated into the hook element HE such that there are no edges at the transition points between the hook element HE and the cover element DE, ie the cover element DE is integrated flush with the hook element HE. In addition, the cover element DE is spherical towards the outside, but at least spherical sector-shaped. This means that there are no edges on the hearing aid side that can be sources of noise.
Wie erwähnt weisen die für die Deckelemente DE verwendeten Materialien eine gewisse Porosität, vorzugsweise eine gewisse Offenporosität auf, die durch die beiden Parameter Filterfeinheit und Offenporigkeit definiert werden kann. Im übrigen weist das verwendete Material gemäss einer erfindungsgemässen Ausführungsform eine homogene Struktur - 8 -As mentioned, the materials used for the cover elements DE have a certain porosity, preferably a certain open porosity, which can be defined by the two parameters filter fineness and open porosity. Otherwise, the material used has a homogeneous structure according to an embodiment of the invention - 8th -
aufon
Es hat sich gezeigt, dass, wenn das verwendete Material eine zwischen lOμm und 200μm (Angaben in d50-Werten) liegende Filterfeinheit und eine zwischen 70% und nahezu 100% liegende Offenporigkeit aufweist, besonders gute Ergebnisse erzielt werden können. Allerdings hängt die Wahl dieser Parameter, insbesondere die Filterfeinheit, erheblich von der Dicke des Deckelementes bzw. von dessen Volumen ab. So hat sich herausgestellt, dass zur Reduktion des Gradienten-Effektes ein möglichst grosses Volumen für das Deckelement von Vorteil ist. Allerdings bewirkt eine Vergrösserung des Volumens gleichzeitig eine ungewollte Veränderung der akustischen Impedanz. Damit muss ein Kompromiss zwischen diesen beiden Optimierungsbedingungen gefunden werden, was anhand Fig. 2 weiter erläutert wird.It has been shown that if the material used has a filter fineness between 10 μm and 200 μm (data in d50 values) and an open porosity between 70% and almost 100%, particularly good results can be achieved. However, the choice of these parameters, in particular the filter fineness, depends considerably on the thickness of the cover element or on its volume. It has been found that the largest possible volume for the cover element is advantageous for reducing the gradient effect. However, increasing the volume also causes an unwanted change in the acoustic impedance. A compromise between these two optimization conditions must therefore be found, which is explained further with reference to FIG. 2.
Die folgenden Materialien eignen sich besonders im Zusammenhang mit dieser Erfindung: gesintertes Polymer, Polyäthylen, Schaumkeramik (auch etwa als keramischerThe following materials are particularly useful in connection with this invention: sintered polymer, polyethylene, ceramic foam (also as a ceramic
Schaum bezeichnet) , geschäumtes Polyurethan, gesintertes Glas oder gesintertes Metall .Called foam), foamed polyurethane, sintered glass or sintered metal.
Es wurde bereits darauf hingewiesen, dass das Deckelement aus einem homogenen Material gefertigt ist. In einer weiteren Ausführungsform der Erfindung wird vorgeschlagen, die Aussenseite des Deckelementes mit einer dünnen, feinporigen Schicht zu überziehen. Diese Schicht besteht vorzugsweise aus Teflon. Die Vorteile einer solchen Schicht bestehen darin, dass die chemische Beständigkeit erhöht - 9 -It has already been pointed out that the cover element is made of a homogeneous material. In a further embodiment of the invention it is proposed to cover the outside of the cover element with a thin, fine-pored layer. This layer is preferably made of Teflon. The advantages of such a layer are that the chemical resistance increases - 9 -
ist, was den Einsatz der erfindungsgemässen Hörgeräte bei starken äusseren Einflüssen ermöglicht . Während beim normalen alltäglichen Einsatz ein Abstossen von Wasser, Körperschweiss und Körperfett notwendig und gefordert ist, ist in speziell gelagerten Fällen auch ein Abstossen von anderen chemischen Substanzen denkbar und auch wünschenswert .is what enables the use of the hearing aids according to the invention in the event of strong external influences. While in normal everyday use repelling water, body sweat and body fat is necessary and required, in specially stored cases, repelling other chemical substances is also conceivable and desirable.
Von grösster Bedeutung für den täglichen Einsatz von Hörgeräten ist deren Wetterbeständigkeit, die dadurch erreicht wird, dass ein hydrophobes Material für das Deckelement zum Einsatz kommt oder dass zumindest die Oberfläche mit einem hydrophoben Material behandelt bzw. beschichtet ist.Of great importance for the daily use of hearing aids is their weather resistance, which is achieved by using a hydrophobic material for the cover element or by at least treating or coating the surface with a hydrophobic material.
Fig. 2 zeigt, in perspektivischer Darstellung, das erfindungsgemässe Deckelement DE für das Hörgerät gemäss Fig. 1. Ersichtlich sind eine nach Aussen gerichtete Fläche AF und nach Innen gerichtete Flächen IF. Die Unterteilung der Fläche AF in drei Teilflächen ist lediglich für eine deutliche Darstellung der Oberflächenkrümmungen vorgenommen worden und hat ansonsten keine Bedeutung. Das gleiche trifft zu für die vier Teilflächen der nach Innen gerichteten Fläche IF.FIG. 2 shows, in perspective representation, the cover element DE according to the invention for the hearing aid according to FIG. 1. An outward-facing surface AF and inward-facing surfaces IF can be seen. The subdivision of the area AF into three partial areas has only been carried out for a clear representation of the surface curvatures and is otherwise of no significance. The same applies to the four partial areas of the inward area IF.
Das in Fig. 2 dargestellte Deckelement DE weist aufgrund der Grossvolumigkeit ein gutes Verhalten in bezug auf den Gradienten-Effekt auf. Allerdings bestehen aufgrund dieser Grossvolumigkeit Einschränkungen in bezug auf die akustische Impedanz und in bezug auf die - 10 -The cover element DE shown in FIG. 2 has good behavior in relation to the gradient effect due to the large volume. However, due to this large volume, there are restrictions with regard to the acoustic impedance and with respect to the - 10 -
Körperschalleigenschaften des Hörgerätes . Dem kann dadurch entgegengesteuert werden, indem die Feinporigkeit vorzugsweise bei 80 bis lOOμm (d50-Werte) gewählt wird.Structure-borne noise properties of the hearing aid. This can be counteracted by selecting the fine porosity preferably at 80 to 100 μm (d50 values).
Fig. 3 zeigt - wie Fig. 1 - ein erfindungsgemässes Hörgerät im Längsschnitt, wobei für die einzelnen Teile die gleichen Bezugszeichen verwendet wurden, wie sie bereits beim Hörgerät gemäss Fig. 1 eingesetzt wurden.3 shows - like FIG. 1 - a hearing aid according to the invention in longitudinal section, the same reference numerals being used for the individual parts as were already used for the hearing aid according to FIG. 1.
Wie aus Fig. 3 ersichtlich ist, ist das Deckelement DE bei dieser Ausführungsform im Randbereich abgerundet. Entsprechend ist die Ausnehmung im Hakenelement HE zur Aufnahme des Deckelementes DE der äusseren Form desselben angepasst worden. Diese Ausführungsform der Erfindung hat den zusätzlichen Vorteil, dass eine kompaktere und somit stabilere Bauweise erreicht wird als bei der AusführungsVariante gemäss Fig. 1. Das Deckelement DE wird nämlich nunmehr vom Hakenelement HE derart umfasst, dass die Bewegungs reiheit des Deckelementes DE in radialer Richtung eingeschränkt wird. Für die Montage und Demontage kann das Deckelement DE senkrecht zur Schnittebene gemäss Fig. 3 bewegt werden.As can be seen from FIG. 3, the cover element DE is rounded off in the edge region in this embodiment. Correspondingly, the recess in the hook element HE for receiving the cover element DE has been adapted to its outer shape. This embodiment of the invention has the additional advantage that a more compact and thus more stable construction is achieved than in the embodiment variant according to FIG. 1. The cover element DE is now embraced by the hook element HE such that the freedom of movement of the cover element DE is restricted in the radial direction becomes. For assembly and disassembly, the cover element DE can be moved perpendicular to the cutting plane according to FIG. 3.
In Fig. 4 ist das Deckelement DE, das in das Hörgerät gemäss Fig. 3 einsetzbar ist, dargestellt. Neben den bereits anhand Fig. 3 erläuterten Unterschieden gegenüber der Ausführungsform gemäss Fig. 1 bzw. 2 ist das Deckelement DE gemäss Fig. 4 als Schale ausgebildet, d.h. die nach aussen gerichteten Flächen bleiben unverändert, jedoch das Volumen aus porösem Material wird reduziert. Bei - 11 -FIG. 4 shows the cover element DE, which can be inserted into the hearing aid according to FIG. 3. In addition to the differences already explained with reference to FIG. 3, compared to the embodiment according to FIGS. 1 and 2, the cover element DE according to FIG. 4 is designed as a shell, ie the outward-facing surfaces remain unchanged, but the volume made of porous material is reduced. at - 11 -
einer solchen Schalenform wird die Filterfeinheit vorzugsweise zwischen 10 bis 40μm gewählt, wobei die Dicke der Schale dabei mindestens 0,5mm beträgt.In such a bowl shape, the filter fineness is preferably chosen between 10 to 40 μm, the thickness of the bowl being at least 0.5 mm.
Schliesslich ist in Fig. 5 eine Ausführungsform einesFinally, in Fig. 5 is an embodiment of a
Hörgerätes dargestellt, bei der zwei Mikrophone Ml und M2 zur Veränderung der Richtcharakteristik zum Einsatz kommen. Erfindungsgemäss werden hierbei die beiden Mikrophone Ml und M2 unter dem selben Deckelement DE angeordnet . Das Deckelement DE ist als Schale ausgebildet und begrenzt einen Raum V, der Schalleintrittsöffnungen SEI und SE2 aufweist, in deren Umgebung je eines der Mikrophone Ml und M2 angeordnet sind.Hearing aid shown, in which two microphones Ml and M2 are used to change the directional characteristic. According to the invention, the two microphones M1 and M2 are arranged under the same cover element DE. The cover element DE is designed as a shell and delimits a space V which has sound entry openings SEI and SE2, in the vicinity of which one of the microphones M1 and M2 are arranged.
Bekanntlich ist es bei der Verwendung von mehrerenAs is well known, it is when using several
Mikrophonen zur Veränderung der Richtcharakteristik von grösster Bedeutung, dass die Charakteristiken der Mikrophone identisch sind. Dies wird im höchsten Masse dadurch erreicht, dass beide Mikrophone Ml und M2 unter dem selben Deckelement DE angeordnet sind, womit auch dieMicrophones for changing the directional characteristic of the greatest importance that the characteristics of the microphones are identical. This is achieved to the greatest extent that both microphones M1 and M2 are arranged under the same cover element DE, which also means that
Volumen V vor den Mikrophonen Ml und M2 identisch sind. Unvermeidbare Verschmutzungen auf der nach aussen gerichteten Oberfläche des Deckelementes DE haben gleiche Einflüsse auf beide Mikrophone Ml und M2.Volume V in front of the microphones Ml and M2 are identical. Unavoidable contamination on the outward surface of the cover element DE has the same effects on both microphones Ml and M2.
In Fig. 6 ist ein In-dem-Ohr- (IdO) -Hörgerät dargestellt, wobei in Fig. 6A ein Querschnitt und in Fig. 6B eine Draufsicht dargestellt ist. In Fig. 6A ist mit DE wiederum das Deckelement bezeichnet, mit Hilfe dessen eine Schalleintrittsoffnung SE abgedeckt ist. Des weiteren ist - 12 -FIG. 6 shows an in-the-ear (ITE) hearing aid, a cross section being shown in FIG. 6A and a top view in FIG. 6B.

Gegenüber den Hörgeräten gemäss Fig. 1 bis 5 unterscheidet sich die IdO-Ausführungsform gemäss Fig. 6 vor allem durch eine andere Anordnung der einzelnen Hörgerätkomponenten. Dadurch wird jedoch vom erfindungsgemässen Prinzip nicht abgewichen.Compared to the hearing aids according to FIGS. 1 to 5, the ITE embodiment according to FIG. 6 differs primarily by a different arrangement of the individual hearing aid components. However, this does not deviate from the principle according to the invention.
