Hörgerät zum Empfang induktiver Üb er tragungenHearing aid for receiving inductive transmissions
Die Heuerung "betrifft ein Hörgerät, zum Empfang induktiver Übertragungen im Hörbereich aus einen magnetischen Feld, das von einer in Kaum angeordneten induktiven Schleife mit einer oder mehreren Windungen, die als Primärkreis wirken, ausgeht» Dabei sind diese Windungen bzw» die induktive Schleife unter entsprechender Anpassung an einen [Donverstärker angeschlossen.The hiring "relates to a hearing aid for receiving inductive transmissions in the listening area from a magnetic field generated by a barely arranged inductive loop with one or more Windings, which act as a primary circuit, go out »Here are these Windings or »the inductive loop with appropriate adaptation connected to a [Don amplifier.

Die Neuerung befasst sich mit an sich bekannten Hörgeräten? die. so verbessert werden, dass sie auch in Filmtheatern oder dgl= ohne Einbuße an Klangtreue und Tonqualität benutzt v/erden können. Der übliche Empfang bei solchen Geräten über ein eingebautes Mikrofon ist in Filmtheatern und in anderen geräuscherfüllten Bäumen nicht befriedigend, üa Nachhallerscheinungen und eine, gleichseitige Verstärkung auch der Störgeräusche die Wiedergabequaiität beeinträchtigen» Diese Nachteile ergeben sich z<.B<, auch, v;enn solche Hörgeräte, im Bühnenbetrieb oder in der Studiotechnik benutzt v/erden sollen, wenn der Regisseur bestimmte Personen ansprechen will.The innovation deals with hearing aids known per se ? the. can be improved so that they can also be used in movie theaters or the like without any loss of fidelity or sound quality. The usual reception in such devices via a built-in microphone is not satisfactory in movie theaters and in other noise-filled trees, üa reverberation phenomena and one equilateral gain and the noise affect the Wiedergabequaiität "These disadvantages arise z <.B ', also v; hen Such hearing aids should be used on stage or in studio technology if the director wants to address certain people.
Durch die Heuerung sollen die geschilderten Mangel beseitigt werden« und zwar dadurch, dass an das Hörgerät eine als. Sekundärkreis der Übertragung wirkende Spule mit Ferritkern anschliessbar isto Zweckmässigerweise wird dieser Ferritkern als Stab ausgebildet» Ein solcher Stab ergibt einen optimalen Empfang, wenn er in einer bestimmten Bichtung zur Foldrichtung der magnetischen Induktionsschleife eingestellt wird. Gemäss einer Weiterbildung der !Teuerung wird die Spule mit Hilfe eines Steckers, wahlweise anstelle des Mikrofons an ein Hörgerät angeschlossen.By hiring the described deficiencies are to be eliminated " namely by the fact that the hearing aid as. Secondary circuit of the transmission acting coil with ferrite core is connectable This ferrite core is expediently designed as a rod » Such a rod gives an optimal reception if it is in a certain direction to the folding direction of the magnetic induction loop is set. According to a further training of the! Inflation the coil is connected to a hearing aid with the help of a plug, optionally instead of the microphone.
Die Neuerung lässt sich für verschiedene Zwecke mit Erfolg anwenden und ist nicht auf die Verwendung durch Schwerhörige beschränkt» Ss ist vielmehr möglich? dass auch Personen mit normalem Gehör die Neuerung verwenden, beispielsweise wenn gewisse Personenkreise,, wie bereits erwähnt auf der Bühne oder dgl=,, angesprochen werden sollen, ohne dadurch andere Personenkreise.: au stören»The innovation can be used successfully for various purposes and is not restricted to use by the hard of hearing »Is it rather possible? that even people with normal hearing use the innovation, for example if certain groups of people, as already mentioned on the stage or the like =, should be addressed without disturbing other groups of people .: au »
