Description

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 claim 1.

Hörgeräte weisen eine Schalleintrittsöffnung zum Aufnehmen von Umgebungslauten und eine Schallaustrittsöffnung zur Abgabe der im Hörgerät verarbeiteten Umgebungslaute auf. Dabei ist es von grösster Bedeutung, dass den 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.Hearing aids have a sound entry opening for recording of ambient sounds and a sound outlet opening for Delivery of the ambient sounds processed in the hearing aid. It is of the utmost importance that the Surrounding sounds in no way disturbing noises are superimposed, which subsequently like ambient sounds be treated. Annoying noises can The reason for this is that air currents on edges on or tear off near the hearing aid (demolition problem) or that air currents with different Speeds and / or directions in the area immediately in front of the microphone membrane cause this is moved (gradient problem). These two The causes mentioned can also occur in combination.

In der US-4 073 366 ist ein Deckelement beschrieben, das über die Schalleintrittsöffnung 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.A cover element is described in US Pat. No. 4,073,366 glued over the sound inlet opening of a hearing aid becomes. The known cover element consists of several Layers that are glued together at the edges and that consist of porous materials, which are prevented is said to be on the edges of the inlet opening as a result of interfering noises occur when air currents break off.

Es hat sich gezeigt, dass mittels dieser bekannten Lehre die Störgeräusche insgesamt nur gering beeinflusst werden können, denn durch das Deckelement über der 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 Schalleintrittsöffnung 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.It has been shown that by means of this known teaching the overall noise is influenced only slightly can, because through the cover element over the Admission opening can admittedly be due to the formation of noise the gradient problem can be reduced, but not the noise caused by the demolition problem arise. The reason for this is that through the Attach cover elements above the sound inlet opening to reduce stall at their edges new potential flock of noise at the edges of the Cover element itself. This is the source for Noise has just 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 Schalleintrittsöffnung 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 dieser Druckschrift nicht entnehmbar. Es handelt sich hier allein darum, die Verschmutzung von Hörgeräten zu vermeiden.For the sake of completeness, reference is made to EP-0 310 866, which discloses that the Sound outlet opening to prevent the entry of Ear wax (cerumen) in the hearing aid with a Cover element, using a microporous material is proposed. Furthermore can be seen from this document that the Sound entry opening then covered with a cover element should be, provided it is an in-the-ear hearing aid (ITE hearing aid) acts, because obviously only exists then there is a risk of ear wax getting into the hearing aid arrives when it is placed in the ear. Measures for Reduction of annoying noises are from this Document cannot be removed. It is alone here to avoid pollution 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 based on 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 task is carried out in the characterizing part of the Measures specified claim 1 solved. Advantageous embodiments of the invention are in others Claims specified.

Die Erfindung weist folgende Vorteile auf: Durch die Integration mindestens eines Deckelementes in das Hörgerät selbst und die oberflächenhündige Anordnung des 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.The invention has the following advantages: Integration of at least one cover element in the hearing aid itself and the surface arrangement of the Cover element in the hearing aid housing edges are avoided, which are otherwise a source of noise, with which the Demolition problem is taken into account. At the same time but also the gradient problem is taken into account, by the cover element made of a porous, preferably is made of an open porous material and a certain Has 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 10µm und 200µm und die Offenporigkeit zwischen 70 und nahezu 100% liegen.It has been shown that material for the Cover elements an open-pored polyethylene is particularly suitable. The properties of the material can on the one hand due to the filter fineness, the minimum particle size of the filtered particles, and on the other hand through the open porosity, which is the relationship between Pore opening and remaining area corresponds to, characterized will. The filter fineness is also around d50 values given, with the specified d50 value 50% of the particles pass the filter and retain 50% of the particles will. It has been found that the d50 values for the filter fineness between 10µm 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.By using a homogeneous material for the Cover elements will be highly reproducible reached because there are no material transfers, which the acoustic properties of the overall system can have a lasting impact, because material transitions involve the risk of deviations from the acoustic Norm behavior arise. Furthermore, both the manufacturing as well as the assembly of the cover elements according to the invention in Hearing aids much easier and therefore also cheaper.

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, there is a variant of the Invention in that made of a homogeneous material manufactured cover elements with a thin permeable Layer, for example Teflon, are coated. This results in a higher resistance, which is especially the case with external chemical influences is of great importance. About that however, the demolition problem is also taken into account worn, because the cover element is given by the coating a finer surface. With this, demolition noise, which due to bumps in the surface of the Cover elements are generated, further reduced.

Fig. 1 zeigt einen Längsschnitt durch ein erfindungsgemässes Hörgerät bestehend aus einem Verstärkungselement VE und einem Hakenelement HE. Das Hakenelement HE ist dabei lösbar mit dem Verstärkungselement VE verbunden, d.h. das Hakenelement HE bzw. das Verstärkungselement VE können beliebig ausgetauscht bzw. ersetzt werden. Fig. 1 shows a longitudinal section through a Hearing aid according to the invention consisting of a Reinforcing element VE and a hook element HE. The Hook element HE is detachable with the Reinforcing element VE connected, i.e. the hook element HE or the reinforcement element VE can be any exchanged or replaced.

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.In the reinforcing element VE is essentially electronic processing of acoustic signals (see Arrow ES) made - after processing - to the Hook element HE (see arrow SS) or in one of them contained sound transmission channel UEK be passed. On the reinforcement element VE of the hearing aid is on this Do not go further as the invention in particular on the equipment of the hook element HE is directed.

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 consisting of two Parts, namely reinforcement element VE and hook element HE, consist. Rather, the invention is particularly suitable also 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 as well as BTE (behind-the-ear) hearing aids be applied.

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. In view of the present invention, the outer one Shape of the reinforcement element VE important: Especially in the transition area between Reinforcement element VE and hook element HE - again in with respect to the embodiment according to FIG. 1 - have this identical - but at least similar - contours and Surface textures. Overall, the whole shows hearing aid according to the invention no sharp edges, so no disturbing noises are generated.

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 especially for this there to record ambient sounds as smoothly as possible and - in the direction of arrow ES - into the reinforcement unit VE transfer. On the other hand, the processed acoustic Signals - in the direction of arrow SS - through the Sound transmission channel UEK in the hook element HE to one Sound outlet opening SA transmitted where the acoustic Signals in the actual auditory canal of the hearing aid wearer reach.

Erfindungsgemäss ist im Hakenelement HE ein Deckelement DE vorgesehen, der den Bereich der Schalleintrittsöffnung 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 in the hook element HE provided that the area of the sound inlet opening SE covering the outside environment, the cover element DE is integrated into the hook element HE in such a way that none Edges at the transition points between the hook element HE and the cover element DE are present, i.e. the cover element DE is integrated flush with the hook element HE. In addition, the cover element DE is against the outside spherical, but at least spherical sector-shaped. 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 auf.As mentioned, the ones used for the cover elements DE Materials have a certain porosity, preferably one certain open porosity due to the two parameters Filter fineness and open porosity can be defined. in the the other material used according to one Embodiment according to the invention a homogeneous structure on.

Es hat sich gezeigt, dass, wenn das verwendete Material eine zwischen 10µm 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 one between 10µm and 200µm (data in d50 values) lying filter fineness and a between 70% and almost 100% open porosity, particularly good Results can be achieved. However, the choice depends this parameter, especially the filter fineness, considerably from the thickness of the cover element or from its Volume. So it turned out that reduction the largest possible volume for the gradient effect the cover element is advantageous. However, one does Increase in volume at the same time an unwanted Change in acoustic impedance. With that a Compromise between these two optimization conditions can be found, which is further explained with reference to FIG. 2.

Die folgenden Materialien eignen sich besonders im Zusammenhang mit dieser Erfindung: gesintertes Polymer, Polyäthylen, Schaumkeramik (auch etwa als keramischer Schaum bezeichnet), geschäumtes Polyurethan, gesintertes Glas oder gesintertes Metall.The following materials are particularly suitable for Connection with this invention: sintered polymer, Polyethylene, foam ceramic (also as a ceramic 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 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.It has already been noted that the cover element is made of a homogeneous material. In a Another embodiment of the invention proposes the outside of the cover element with a thin, to coat fine-pored layer. This layer exists preferably made of Teflon. The advantages of such a layer consist in that the chemical resistance increases is what the use of the hearing aids according to the invention strong external influences. While at water repelling in normal everyday use, Body sweat and body fat is necessary and required, is also a rejection of in special cases other chemical substances conceivable and also 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 the utmost importance for the daily use of Hearing aids is their weather resistance, the result is achieved that a hydrophobic material for the Cover element is used or that at least the Surface treated with a hydrophobic material or is coated.

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, that Cover element DE according to the invention for the hearing aid according to Fig. 1. An outward-facing surface can be seen AF and inward facing areas IF. The subdivision the area AF in three partial areas is only for one clear representation of the surface curvatures been and has no other meaning. The same applies to the four partial areas of the interior facing 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 Körperschalleigenschaften des Hörgerätes. Dem kann dadurch entgegengesteuert werden, indem die Feinporigkeit vorzugsweise bei 80 bis 100µm (d50-Werte) gewählt wird.The cover element DE shown in FIG. 2 has good behavior with regard to the large volume Gradient effect. However, due to this Large volume restrictions regarding the acoustic impedance and in relation to the Structure-borne noise properties of the hearing aid. That can do that can be counteracted by the fine porosity is preferably chosen 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 for the individual parts Reference numerals were used, as they were in the Hearing aid according to FIG. 1 were used.

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 Bewegungsfreiheit 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 at this embodiment rounded in the edge area. The recess in the hook element HE is accordingly Inclusion of the cover element DE of its outer shape been adjusted. This embodiment of the invention has the additional advantage of being a more compact and therefore more stable construction is achieved than with the Design variant according to FIG. 1. The cover element DE is namely now includes hook element HE in such a way that the freedom of movement of the cover element DE in radial Direction is restricted. For assembly and disassembly can cover element DE perpendicular to the section plane according to Fig. 3 are moved.

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 Ausfuhrungsform 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 einer solchen Schalenform wird die Filterfeinheit vorzugsweise zwischen 10 bis 40µm gewählt, wobei die Dicke der Schale dabei mindestens 0,5mm beträgt.In Fig. 4 is the cover element DE, which in the hearing aid 3 can be used. In addition to the compared to the differences already explained with reference to FIG. 3 1 or 2 is the embodiment 4 is designed as a shell, i.e. the outward-facing areas remain unchanged, however, the volume of porous material is reduced. At Such a shell shape becomes the filter fineness preferably chosen between 10 to 40 µm, the thickness the shell is at least 0.5mm.

Schliesslich ist in Fig. 5 eine Ausführungsform eines Hörgerätes dargestellt, bei der zwei Mikrophone M1 und M2 zur Veränderung der Richtcharakteristik zum Einsatz kommen. Erfindungsgemäss werden hierbei die beiden Mikrophone M1 und M2 unter dem selben Deckelement DE angeordnet. Das Deckelement DE ist als Schale ausgebildet und begrenzt einen Raum V, der Schalleintrittsöffnungen SE1 und SE2 aufweist, in deren Umgebung je eines der Mikrophone M1 und M2 angeordnet sind.Finally, in Fig. 5 is an embodiment of a Hearing aid shown in the two microphones M1 and M2 used to change the directional characteristic. According to the invention, the two microphones M1 and M2 arranged under the same cover element DE. The Cover element DE is designed and limited as a shell a room V, the sound inlet openings SE1 and SE2 has in the vicinity of each one of the microphones M1 and M2 are arranged.

Bekanntlich ist es bei der Verwendung von mehreren 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 M1 und M2 unter dem selben Deckelement DE angeordnet sind, womit auch die Volumen V vor den Mikrophonen M1 und M2 identisch sind. Unvermeidbare Verschmutzungen auf der nach aussen gerichteten Oberfläche des Deckelementes DE haben gleiche Einflüsse auf beide Mikrophone M1 und M2.As is well known, it is when using several Microphones for changing the directional characteristic of paramount importance that the characteristics of the Microphones are identical. This will be the highest achieved in that both microphones M1 and M2 under the the same cover element DE are arranged, with which the Volume V in front of the microphones M1 and M2 are identical. Unavoidable pollution on the outside directed surface of the cover element DE have the same Influences on both microphones M1 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 Schalleintrittsöffnung SE abgedeckt ist. Des weiteren ist ein Schallkanal UEK ersichtlich, durch den die Schallwellen zu einem Mikrophon M geleitet werden. Der Vollständigkeit halber ist in Fig. 6A auch eine Batterie BT und ein die Elektronik enthaltendes Gehäuse E eingezeichnet.6 shows an in-the-ear (ITE) hearing aid, 6A is a cross section and FIG. 6B is a cross section Top view is shown. 6A is again with DE referred to the cover element, with the help of which one Sound inlet opening SE is covered. Furthermore is a sound channel UEK can be seen through which the sound waves to be directed to a microphone M. Completeness for the sake of FIG. 6A there is also a battery BT and a Electronics-containing housing E is shown.

In der Draufsicht gemäss Fig. 6B ist das Deckelement DE erkennbar, das in dieser Ausführungsform vorzugsweise als Kugelsektor ausgebildet ist.6B is the cover element DE recognizable that in this embodiment preferably as Ball sector is formed.

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 6 the ITE embodiment according to FIG a different arrangement of the individual hearing aid components. However, this does not detract from the principle according to the invention deviated.
