Abstract

The aim is to improve a process and device for transmitting sound with the aid of at least one sound-transmission element which emits sound signals that can be perceived by a person, so as to ensure that low-frequency sound signals, as well as medium- and higher-frequency sound signals, can be transmitted very effectively in a technically simple and therefore inexpensive manner. To that end it is proposed that at least one sound-transmission element should be so arranged on the listener's body as to create a direct sound-transmission pathway from the sound transmission element via the Eustachian tubes to the auditory ossicles.

Description

Die Erfindung betrifft ein Verfahren zur Übertragung von Schall mittels wenigstens eines Schallübertragungsmittels, welches von einer Person wahrnehmbare Schallsignale abgibt.The invention relates to a method for the transmission of Sound by means of at least one sound transmission means, which sound signals perceivable by a person delivers.

Derartige Verfahren dienen beispielsweise dazu, um von einem Mikrofon aufgenommene oder auf einem Tonträger aufgezeichnete Musik zu übertragen. Dabei ist das Schallübertragungsmittel ein Lautsprecher oder auch ein Kopfhörer, der Schallsignale derart abgibt, daß sie an das menschliche Gehör über das Trommelfell ankoppeln. Durch in Räumen plazierte oder in Kopfhörern angeordnete Lautsprecher wird das Trommelfell in Schwingungen versetzt, die von dem Hörorgan der Person verarbeitet werden. Im einzelnen laufen die ankommenden Schallsignale durch den Gehörgang zum Trommelfell und versetzen dieses in Schwingungen, die auf die Gehörknöchelchen übertragen werden. Das dritte Knöchelchen leitet diese Schwingungen über das sogenannte ovale Fenster an das Hörorgan weiter.Such methods are used, for example, to: recorded on a microphone or on a sound carrier to transfer recorded music. It is Sound transmission means a speaker or also a Headphones that emit sound signals so that they are on connect human hearing through the eardrum. By placing them in rooms or placing them in headphones Speakers will make the eardrum vibrate offset processed by the person's hearing organ become. The incoming sound signals run in detail through the ear canal to the eardrum and move it in vibrations that are transmitted to the ossicles become. The third ankle guides these vibrations through the so-called oval window to the hearing organ.

Problematisch bei diesem bekannten Verfahren zur Übertragung von Schall sind nun Schallsignale mit Frequenzen etwa unterhalb 700 Hz. Da nämlich das menschliche Gehör besonders empfänglich ist für Frequenzen im Bereich zwischen 700 und 6000 Hz, genügt ein relativ geringer Schalldruck, um diese Frequenzen wahrzunehmen. Dagegen ist ein wesentlich höherer Schalldruck erforderlich, um auch noch Frequenzen unterhalb 700 Hz wahrzunehmen. Diese Eigenschaft des menschlichen Gehörs erweist sich insbesondere bei der Übertragung von Musik als sehr nachteilig, da in diesem Falle eine starke Dämpfung bei niederfrequenten Schallsignalen unterhalb 700 Hz auftritt.Problematic with this known method of transmission from sound are now sound signals with frequencies about below 700 Hz. Because human hearing is particularly susceptible to frequencies in the range between 700 and 6000 Hz, a relatively low one is sufficient Sound pressure to perceive these frequencies. On the other hand a much higher sound pressure is required to also perceive frequencies below 700 Hz. This The quality of human hearing is particularly evident when transmitting music as very disadvantageous because in this case there is strong attenuation at low frequencies Sound signals below 700 Hz occurs.

Durch diese Dämpfung werden insbesondere gerade die für Rhythmen gebräuchlichen Schallsignale sehr stark in den Hintergrund gedrängt, so daß die übertragene Musik wenig lebendig ist. Um diesem Umstand entgegenzuwirken, sind nun verschiedene Verfahren bekannt, welche eine Erhöhung des Schalldrucks niederfrequenter Schallsignale ermöglichen.Through this damping, especially those for Sound signals used very strongly in the rhythms Background crowded, so that the transmitted music little is alive. To counteract this, are now known various methods, which an increase allow the sound pressure of low-frequency sound signals.

Bei einem bekannten Verfahren wird beispielsweise die Gesamtlautstärke des übertragenen Schalls der Musik erhöht. Hierdurch werden die niederfrequenten Schallsignale im Vergleich zu den mittel- und höherfrequenten Schallsignalen lauter, da die Dämpfungskurve mit steigendem Schalldruck flacher wird.In a known method, for example Overall volume of the transmitted sound of the music elevated. As a result, the low-frequency sound signals compared to the medium and higher frequencies Sound signals louder because the attenuation curve increases with Sound pressure becomes flatter.

Nachteilig bei diesem Verfahren ist jedoch, daß auch die mittel- und höherfrequenten Schallsignale einen höheren Schalldruckpegel und damit eine wesentlich höhere Lautstärke aufweisen, die im Extremfall so hoch ist, daß die Schmerzschwelle einer Person erreicht oder überschritten wird. Hierdurch wird das Trommelfell überbelastet, was langfristig Hörschäden zur Folge hat.A disadvantage of this method, however, is that the medium and higher frequency sound signals a higher Sound pressure level and thus a much higher one Have volume that is so high in extreme cases that a person's pain threshold is reached or exceeded becomes. This will overload the eardrum which results in long-term hearing damage.

Bei einem anderen bekannten Verfahren werden lediglich die niederfrequenten Schallsignale gegenüber den mittel- und/oder höherfrequenten Schallsignalen gezielt verstärkt. Dies hat den Vorteil, daß im mittel- und höherfrequenten Frequenzbereich die Schmerzschwelle nicht erreicht wird. Nachteilig bei diesem Verfahren ist jedoch, daß zu seiner Realisierung aufwendige Verstärker mit einer variablen Verstärkungsleistung (Faktor etwa zwischen 1 und 10 Mio.) erforderlich sind, die äußerst aufwendig zu realisieren und daher kostspielig sind, und darüber hinaus auch einen beträchtlichen Energiebedarf aufweisen. Außerdem sind hierfür auch aufwendige Schallübertragungsmittel, beispielsweise große Lautsprecher, erforderlich, die aufgrund ihrer aufwendigen und großen Bauart nur mit erheblichem Aufwand transportiert werden können.In another known method, only the low-frequency sound signals compared to the medium and / or higher-frequency sound signals. This has the advantage that in the medium and higher frequencies Frequency range the pain threshold does not is achieved. This method is disadvantageous however, that for its realization complex amplifiers with a variable gain power (factor about between 1 and 10 million) are required, the extreme complex to implement and therefore expensive, and also a considerable amount of energy exhibit. In addition, there are also expensive sound transmission means, for example large speakers, required because of their elaborate and large size Type can only be transported with considerable effort can.

Aus diesem Grunde kommen derartige Verfahren praktisch nur in großen Kinos, Diskotheken und dgl. zur Anverwendung. Sie sind jedoch für den Privatgebrauch aus den genannten Gründen praktisch nicht realisierbar. For this reason, such methods come in handy only for use in large cinemas, discotheques and the like. However, they are for private use from the above Reasons practically not feasible.

Aus der EP 0 553 525 Al geht eine Vorrichtung zur Übertragung von Schall hervor, bei der Schallübertragungsmittel im Bauch- bzw. im Rückenbereich einer Person angeordnet sind. Insbesondere bei der Anordnung des Schallübertragungsmittels im Bauchbereich, aber auch bei der Anordnung im Rückenbereich findet eine verhältnismäßig hohe Dämpfung des Schalls bereits auf kurzen Wegen statt, da die unter dem Schallübertragungsmittel angeordnete Haut, Gewebe und andere Körperteile sehr gute Dämpfungseigenschaften besitzen.EP 0 553 525 A1 discloses a device for Transmission of sound emerges with the sound transmission means in the abdominal or back area of a person are arranged. Especially when arranging the Sound transmission means in the abdominal area, but also in the arrangement in the back area is proportionate high attenuation of the sound in short distances instead because the one located under the sound transmission means Skin, tissues and other parts of the body very good Have damping properties.

Aus der US 4 641 345 ist eine Vorrichtung zur Übertragung von Schall bekannt, bei der das Schallübertragungsmittel auf der Rückseite eines Fahrzeugsitzes angeordnet ist. In diesem Falle ist die Übertragung des Schalls auf den Körper ebenfalls erheblich gedämpft. Die Dämpfung wird hierbei nicht nur aufgrund der im Schallübertragungsweg angeordneten Haut, Gewebes und sonstiger Körperteile, sondern darüber hinaus auch noch durch die Dämpfungseigenschaften des Fahrersitzes hervorgerufen.From US 4,641,345 there is a device for transmission known from sound at which the sound transmission means is arranged on the back of a vehicle seat. In in this case the transmission of the sound to the Body also significantly dampened. The damping will not only because of the sound transmission path arranged skin, tissue and other parts of the body, but also because of the damping properties of the driver's seat.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Übertragung von Schall der gattungsgemäßen Art derart zu verbessern, daß neben den mittel- und höherfrequenten Schallsignalen auch niederfrequente Schall signale auf technisch einfach zu realisierende und daher kostengünstige Weise äußerst wirkungsvoll und insbesondere unter Vermeidung von Dämpfungsverlusten übertragen werden können.The invention has for its object a method for the transmission of sound of the generic type to improve that in addition to the medium and higher frequencies Sound signals also low-frequency sound signals technically easy to implement and therefore cost effective and extremely effective especially while avoiding loss of damping can be transferred.

Diese Aufgabe wird bei einem Verfahren zur Übertragung von Schall der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß man zur Übertragung insbesondere niederfrequenter Schallsignale das Schallübertragungsmittel im Brustbereich in der Nähe des Brustbeins der Person anordnet, so daß sich ein direkter Schallübertragungsweg vom Schallübertragungsmittel über die Eustachie-Röhre zu den Gehörknöchelchen der Person ergibt.This task is done in a transfer procedure of sound of the type described in the opening paragraph of the invention solved in that one in particular for transmission low-frequency sound signals the sound transmission means in the chest area near the sternum Arranges person so that there is a direct sound transmission path from the sound transmission medium to the Eustachia tube to the person's ossicles.

Die Übertragung insbesondere niederfrequenter Schallsignale durch am Brustbein der Person angeordnete Schallübertragungsmittel über die Eustachie-Röhre zu den Gehörknöchelchen hat zum einen den besonders großen Vorteil, daß hierdurch das Trommelfell und damit auch die Trommelfelldämpfung umgangen werden. Auf diese Weise ist keine Dämpfungskompensation durch eine variable Verstärkungsleistung oder dgl. zur gehörrichtigen Übertragung niederfrequenter Schallsignale erforderlich.The transmission of especially low-frequency sound signals by means of sound transmission means arranged on the person's sternum over the Eustachie tube to the On the one hand, the ossicle has the particularly large one Advantage that this causes the eardrum and thus the Tympanic membrane damping can be avoided. That way No damping compensation due to a variable gain or the like for the correct transmission low-frequency sound signals required.

Zum anderen ist es vorteilhaft, daß die Schwingungen durch Anordnung des Schallübertragungsmittels am Brustbein auf den gesamten Brustkorb übertragen werden, da das Brustbein in Verbindung mit den Rippen und über diese wiederum mit dem Rippenfell steht. Der Brustkorb bringt nun wiederum die Luft in den Lungenflügeln zum Schwingen. Von dort gelangen die Schwingungen über die Rachenröhre zur Eustachi-Röhre und von dieser auf die Gehörknöchelchen. Der Vorteil hierbei ist, daß der gesamte Brustkorb als Resonanzkörper verwendet wird und insoweit ein Bandpaßgehäuse, ähnlich dem bekannter Subwoofer, darstellt. Hierdurch werden gerade niederfrequente Schallsignale besonders vorteilhaft unter Umgehung des Trommelfells übertragen.On the other hand, it is advantageous that the vibrations by arranging the sound transmission means on the breastbone to be transferred to the entire rib cage because that Sternum in connection with and over the ribs again stands with the pleura. The chest brings now again the air in the lungs to vibrate. From there, the vibrations pass through the pharynx to the Eustachi tube and from there to the ossicles. The advantage here is that the entire chest is used as a sound box and so far Bandpass housing, similar to the well-known subwoofer. This results in low-frequency sound signals particularly advantageous bypassing the eardrum transfer.

Das Verfahren ist mit einfachen technischen Mitteln zu realisieren und erfordert nur einen verhältnismäßig geringen Energieverbrauch. Es kann damit auch in einer mobilen Vorrichtung eingesetzt werden. The procedure is simple with technical means realize and requires only a proportionate low energy consumption. It can also be used in one mobile device can be used.

Um hierbei den gesamten Frequenzbereich von Schallsignalen übertragen zu können, sieht eine besonders vorteilhafte Ausführungsvariante des Verfahrens vor, daß man die Schallsignale zusätzlich über ein weiteres Schallübertragungsmittel - beispielsweise einen Lautsprecher oder einen Kopfhörer - überträgt, welches eine Ankopplung der Schallsignale an das Trommelfell der Person ermöglicht.To cover the entire frequency range of sound signals To be able to transfer one looks special advantageous embodiment of the method before that one additionally the sound signals over another Sound transmission means - for example a loudspeaker or headphones - which one Coupling the sound signals to the eardrum Allows person.

Auf diese Weise können insbesondere mittel- und/oder höherfrequente Schallsignale auf bekannte Weise über das Trommelfell übertragen werden, wohingegen gleichzeitig niederfrequente Schallsignale unabhängig hiervon zusätzlich besonders effektiv über ein beispielsweise im Bereich des Brustbeins einer Person angeordnetes Schallübertragungsmittel übertragen werden. In this way, in particular medium and / or higher-frequency sound signals in a known manner via the Eardrum are transmitted, whereas at the same time low-frequency sound signals regardless of this additionally particularly effective for example in the Area of the sternum of a person arranged sound transmission means be transmitted.

Als Schallübertragungsmittel kommen an sich bekannte Lautsprecher, aber auch Resonatoren oder ähnliches in Betracht.Known per se come as sound transmission means Speakers, but also resonators or similar in Consideration.

Die erfindungsgemäße Aufgabe wird darüber hinaus auch noch durch eine Vorrichtung zur Übertragung von Schall mit wenigstens einem Schallübertragungsmittel gelöst, bei welchem das wenigstens eine Schallübertragungsmittel im Brustbereich in der Nähe des Brustbeins einer Person angeordnet ist, so daß sich ein direkter Schallübertragungsweg vom Schallübertragungsmittel über die Eustachie-Röhre zu den Gehörknöchelchen der Person ergibt.The object of the invention is also also still by a device for transmitting sound solved with at least one sound transmission means, at which the at least one sound transmission means in Chest area near a person's sternum is arranged so that there is a direct sound transmission path from the sound transmission medium to the Eustachia tube to the person's ossicles.

Insbesondere hinsichtlich einer Auswahl der Schallsignale, die über ein auf diese Weise an dem Brustbein einer Person angeordnetes Schallübertragungsmittel übertragen werden, ist es besonders vorteilhaft, daß das wenigstens eine Schallübertragungsmittel wenigstens einem Verteilermittel nachgeschaltet ist, in dem die Verteilung der Schallsignale vorgenommen wird.In particular with regard to a selection of the sound signals, the one on the sternum in this way sound transmission means arranged to a person transmitted, it is particularly advantageous that the at least one sound transmission means at least one Distribution means is downstream, in which the distribution the sound signals are made.

Rein prinzipiell können als Verteilermittel die unterschiedlichsten Ausführungen vorgesehen sein, vorteilhafterweise umfaßt das wenigstens eine Verteilermittel jedoch wenigstens ein Frequenzfiltermittel.In principle, the most varied can be used as distribution agents Designs may be provided, advantageously comprises the at least one distribution means however at least one frequency filter means.

Hinsichtlich des Frequenzfiltermittels sind die unterschiedlichsten Ausführungsarten denkbar. Vorteilhafterweise ist das Frequenzfiltermittel jedoch ein Tiefpaß, der technisch besonders einfach zu realisieren ist.With regard to the frequency filter means, the most varied Possible designs. Advantageously however, the frequency filter means is a low pass, which is technically particularly easy to implement.

Möglich ist es aber auch, daß das Frequenzfiltermittel eine Frequenzweiche und einen Tiefpaß sowie einen Hochpaß umfassen, wobei die den Hochpaß passierenden mittel- und höherfrequenten Schallsignale mittels eines weiteren Schallübertragungsmittels übertragen werden, welches an das Trommelfell der Person ankoppelnden Schall aussendet.But it is also possible that the frequency filter means a crossover and a low pass and a high pass include, the medium and passing the high pass higher-frequency sound signals by means of another Sound transmission means are transmitted to which the eardrum emits sound coupling to the person.

Als Schallübertragungsmittel kommen hierbei die unterschiedlichsten Ausführungsformen in Betracht. Technisch besonders einfache Ausführungsformen sind Lautsprecher und/oder Resonatoren.The most varied come here as sound transmission means Embodiments into consideration. Technically loudspeakers are particularly simple embodiments and / or resonators.

Das erfindungsgemäße Verfahren zur Übertragung von Schall läßt sich am besten anhand der Fig. 1 erläutern. Wie aus Fig. 1 hervorgeht, werden von einer Signalquelle 40 ausgegebene Schallsignale einem Verteilermittel 50 zugeführt. Rein prinzipiell können als Verteilermittel 50 beliebige Ausführungen in Betracht kommen, so könnte das Verteilermittel 50 beispielsweise ein Frequenzfiltermittel oder eine Frequenzweiche sein, die wiederum beispielsweise durch einen Tiefpaß 20 und einen Hochpaß 30 realisiert sein können. Höherfrequente Schallsignale werden dabei über das Trommelfell 60 auf das Gehörorgan 80 übertragen, wohingegen niederfrequente Schallsignale über das Brustbein 70 auf das Hörorgan 80 übertragen werden. Die Übertragung geschieht dabei beispielsweise durch Lautsprecher 27, 37, wobei der dem Tiefpaß nachgeschaltete Lautsprecher 27 in der Nähe des Brustbeins 70 angeordnet ist, während der dem Hochpaß 37 nachgeschaltete Lautsprecher 37 beispielsweise in Form eines Kopfhörers ausgebildet ist. Es versteht sich, daß auch die niederfrequenten Schallsignale zusätzlich über den Lautsprecher 37 übertragen werden können.The inventive method for the transmission of sound can best be explained with reference to FIG. 1. How from 1 shows a signal source 40 sound signals output to a distribution means 50 fed. In principle, 50 can be used as distribution means any design can be considered, it could Distribution means 50, for example a frequency filter means or a crossover, which in turn for example by a low pass 20 and a high pass 30 can be realized. Higher frequency sound signals are thereby on the eardrum 60 on the auditory organ 80 transmit, whereas low-frequency sound signals transmitted to the hearing organ 80 via the sternum 70 become. The transmission happens, for example through loudspeakers 27, 37, the downstream of the low-pass filter Speaker 27 near the breastbone 70 is arranged, during which the high pass 37 downstream Loudspeaker 37, for example in the form of headphones is trained. It goes without saying that the low-frequency sound signals additionally via the Loudspeaker 37 can be transmitted.

Ein Ausführungsbeispiel einer Vorrichtung zur Übertragung von Schall, dargestellt in Fig. 2, umfaßt ein Schallaufnahme oder -wiedergabegerät 10, beispielsweise ein Kassettenabspielgerät oder ein Mikrofon mit einem nachgeschalteten Verstärker und dgl., welches Signale über eine Signalleitung 11 an das Frequenzfiltermittel in Form eines Tiefpasses 20 und eines Hochpasses 30 ausgibt.An embodiment of a device for transmission of sound, shown in Fig. 2, includes sound recording or playback device 10, for example a Cassette player or microphone with one downstream amplifier and the like. Which signals via a signal line 11 to the frequency filter means in Outputs a low pass 20 and a high pass 30.

Den Tiefpaß 20 passieren nur tieferfrequente Schallsignale, wobei der Tiefpaß 20 so ausgelegt ist, daß ihn nur Schallsignale etwa unterhalb 700 Hz passieren, während mittel- und höherfrequente Schallsignale über 700 Hz von dem Tiefpaß 20 aus den Schallsignalen herausgefiltert werden.Only low-frequency sound signals pass the low-pass filter 20, the low pass 20 is designed so that it only sound signals pass below 700 Hz, while medium and higher frequency sound signals over 700 Hz filtered out of the low-pass filter 20 from the sound signals become.

Dagegen passieren den Hochpaß 30 nur mittel- und/oder höherfrequente Schallsignale über 700 Hz, während Schallsignale unterhalb 700 Hz in dem Hochpaß 30 aus den Schallsignalen weggefiltert werden.In contrast, the high pass 30 pass only medium and / or higher frequency sound signals above 700 Hz while Sound signals below 700 Hz in the high pass 30 from the Sound signals are filtered out.

Dem Tiefpaß 20 sowie dem Hochpaß 30 können jeweils noch auf die entsprechenden Frequenzen ausgelegte Verstärker 25, 35 nachgeschaltet sein, welche Schallübertragungsmittel in Form der Lautsprecher 27, 37 ansteuern.The low pass 20 and the high pass 30 can still each amplifiers designed for the corresponding frequencies 25, 35, which sound transmission means control in the form of speakers 27, 37.

Der Lautsprecher 27 ist dabei - wie oben erwähnt - im Brustbereich in der Nähe des Brustbeins 70 einer Person angeordnet, so daß sich ein direkter Schallübertragungsweg vom Lautsprecher 27 über den Brustkorb, die Eustachie-Röhre, hin zu den Gehörknöchelchen der Person ergibt. Hierbei wirkt der Brustraum der Person als zusätzlicher Resonanzkörper, ähnlich dem eines für die Übertragung niederfrequenter Schallsignale aus der Audio-Technik bekannten Subwoofers.The speaker 27 is - as mentioned above - in Chest area near a person's sternum 70 arranged so that there is a direct sound transmission path from loudspeaker 27 over the rib cage, the eustachia tube, towards the person's ossicles results. Here, the person's chest cavity acts as additional sound box, similar to that for the Transmission of low-frequency sound signals from audio technology known subwoofers.

Der Lautsprecher 37 kann beispielsweise eine an sich bekannte Lautsprecherbox, oder - wie oben ebenfalls bereits erwähnt - ein Kopfhörer oder dgl. sein, der eine Schallankopplung über das Trommelfell 60 einer Person ermöglicht.The loudspeaker 37 can be one in itself, for example known loudspeaker box, or - as above also already mentioned - be a headphone or the like, the one Sound coupling via a person's eardrum 60 enables.

Durch diese Vorrichtung werden mittel- und höherfrequente Schallsignale auf an sich bekannte Weise durch Ankoppelung an das Trommelfell 60 einer Person übertragen, während tieferfrequente Schallsignale im wesentlichen über den Brustraum und die Eustachie-Röhre auf die Gehörknöchelchen des Hörorgans 80 der Person übertragen werden. Hierdurch ergibt sich eine besonders realitätsnahe Übertragung von Schall, insbesondere von Musik.Through this device, medium and higher frequencies are Sound signals in a manner known per se by coupling transferred to a person's eardrum 60, while lower frequency sound signals essentially across the chest and the eustachia tube to the Bones of the auditory organ 80 transmitted to the person become. This results in a particularly realistic result Transmission of sound, especially music.

Eine solche Vorrichtung ist mit einfachen technischen Mitteln zu realisieren. Sie ist leicht, kompakt und transportabel und ist dadurch überall und jederzeit einsetzbar, insbesondere kann sie auch als mobiles Gerät - ähnlich den bekannten Kassetten- oder Compactdisk-Abspielgeräten - ausgeführt werden. Darüber hinaus verbraucht sie nur wenig Energie und kann insoweit auch von Batterien als Energieträger gespeist werden, wodurch sie von externen Energiequellen unabhängig ist. Schließlich ist sie aus den vorgenannten Gründen auch besonders kostengünstig herzustellen und damit auch für den Endverbraucher preiswert zu erstehen.Such a device is simple technical Means to realize. It is light, compact and transportable and is therefore everywhere and at any time usable, in particular it can also be used as a mobile device - Similar to the known cassette or compact disc players - be carried out. Beyond consumed it only has a little energy and can also be used Batteries are fed as an energy source, making them is independent of external energy sources. Finally it is also special for the reasons mentioned above inexpensive to manufacture and therefore also for To buy end consumers inexpensively.
