Abstract

The pref. audio signal, e.g. music, is amplitude modulated in phase with the sync. freq. by means of an amplitude modulator (2) or amplifier of variable amplification factor. Either is controlled by the sync. freq.. Pulsating audio excitation can be provided by an amplitude modulator or voltage controlled amplifier with an input connectable to connectable to an audio reproducing appts. and a control input connectable to a digitally generated sync. freq.. The housing can accommodate a microprocessor (14) controlling LEDs (16) mountable on a pair of spectacles. ADVANTAGE - Attenuates counter-effective upper harmonies. Avoids both monotomy and sudden changes of level or disharmony.

Description

Die Erfindung betrifft ein Verfahren und Gerät zur Stimulation des Gehörsinns oder des Gesichts- und Gehörsinns zum Zwecke der Synchronisation der Gehirnwellen. Es ist bekannt, daß sich die Frequenz der meßbaren Gehirnwellen (EEG) durch äußere periodische Reize auf deren Frequenz einstellen, also synchronisieren kann. Da verschiedene Gehirnfrequenzen mit verschiedenen Bewußtseins­ zuständen (Schlaf, Anstrengung, Entspannung) einhergehen, wird solche Stimulation verwendet zur Auslösung von Entspannung, Anregung oder Stresslösung. Nach dem Stand der Technik gibt es hierzu eigene Geräte ("Brainmachines"), die mittels Mikroprozessorsteuerung periodische Signale an einen Kopfhörer und gleichzeitig an eine mit Lichtquellen versehene Brille gibt.The invention relates to a method and device for stimulation of the sense of hearing or of the face and hearing for the purpose of Brainwave synchronization. It is known that the Frequency of measurable brain waves (EEG) by external periodic Set stimuli to their frequency, i.e. can synchronize them. Because different brain frequencies with different consciousness conditions (sleep, exertion, relaxation) go hand in hand such stimulation is used to trigger relaxation, Suggestion or stress relief. According to the state of the art there is own devices ("Brainmachines") that use Microprocessor control periodic signals to a headphone and at the same time on glasses equipped with light sources.

Dieses Verfahren hat den Nachteil, daß die klangliche Gestaltung der Tonimpulse sehr eingeschränkt ist und daher für den Benützer rasch ermüdend oder unangenehm wirkt. Außerdem wirkt der vom Mikroprozessor erzeugte Ton deshalb störend, weil meistens zur Entspannung zusammen mit den Tonimpulsen Musik wiedergegeben wird, wobei tonliche Disharmonien auftreten.This method has the disadvantage that the sonic design the sound impulse is very limited and therefore for the User quickly becomes tired or uncomfortable. In addition, the Sound generated by the microprocessor is annoying because it mostly does music played together with the sound impulses for relaxation with tonal disharmonies.

Weiterer Nachteil: Da die Wellenform der erzeugten Töne einer Rechtechform gleicht, also einem harten ein- und ausschalten entspricht, werden durch den Oberwellengehalt, besonders bei tiefen Frequenzen z. B. 2-10 Hertz, haupsächlich höherfrequente Gehirnwellen angeregt, die dann die gewünschte Wirkung verhindern.Another disadvantage: Since the waveform of the generated tones is one Legal form is like turning a hard one on and off corresponds to the harmonic content, especially at low frequencies e.g. B. 2-10 Hertz, mainly higher frequencies Brain waves are stimulated, which then have the desired effect prevent.

Aufgabe der vorliegenden Erfindung ist ein Verfahren und Gerät, das die genannten Nachteile überwindet. Dies wird nach Anspruch 1 dadurch gelöst, daß ein beliebiges Tonsignal (1), zum Beispiel Musiksignal, mittels eines Amplitudenmodulators (2) oder Verstärkers mit steuerbarer Verstärkung (VCA), im Takt der Synchronisationsfrequenz amplitudenmoduliert wird, wobei der Modulator oder VCA von der Synchronisationsfrequenz angesteuert wird, zum Beispiel durch einen Mikroprozessor (5). The object of the present invention is a method and device which overcomes the disadvantages mentioned. This is achieved according to claim 1 in that any sound signal ( 1 ), for example a music signal, is amplitude-modulated in time with the synchronization frequency by means of an amplitude modulator ( 2 ) or amplifier with controllable gain (VCA), the modulator or VCA being based on the synchronization frequency is controlled, for example by a microprocessor ( 5 ).

Die durch die Amplitudenmodulation der Muaik aufgeprägte Synchronisationsfrequenz ist dabei indirekt hörbar. Dies bewirkt physiologisch eine sogar noch wirksamere Synchronisation als eine einfacher Tonimpulsfolge, da der Träger, der in diesem Fall die Musik ist, ständigen Veränderungen unterworfen ist.The one impressed by the amplitude modulation of the Muaik The synchronization frequency can be heard indirectly. this causes physiologically an even more effective synchronization than one simple sequence of sound pulses, since the carrier, in this case the Music is subject to constant change.

Das Tonsignal kann dabei nach Anspruch 2) z. B. aus einem in das Gerät eingebauten Casettenspieler stammen oder auch nach Anspruch 3) aus einem zusätzlichen an das Gerät angeschlossenen Walkman. Die Amplitudenmodulator kann eingebaut sein in das für die Erzeugung der Synchronisationsfrequenz vorgesehene Mikroprozessorgerät, oder kann in einem eigenen Gehäuse untergebracht sein, welches einen Anschluß an bestehende "Brainmachines" ermöglicht.The sound signal can be according to claim 2) z. B. from one to that Device built-in cassette player originate or also according to claim 3) from an additional Walkman connected to the device. The amplitude modulator can be built in for that Generation of the synchronization frequency provided Microprocessor device, or can be in its own housing be housed, which has a connection to existing "Brainmachines" enables.

Um die oben erwähnten Oberwellen zu vermeiden, ist nach Anspruch 5 ein R-C- Glied vorgesehen, welches zum Beispiel als Tiefpaß vor den Steuereingang geschaltet ist und die Flanken des Ein- und Abschaltvorganges abschrägt.To avoid the harmonics mentioned above, after Claim 5 an R-C link provided which, for example, as Low pass is connected before the control input and the edges of the The switch-on and switch-off process bevels.

Gleichzeitig kann zur optischen Stimulation eine Lichtquelle 10 vorgesehen sein, welche in eine Brille 11 angebracht ist und auch von dem Mikroprozessor 5 gesteuert wird.At the same time, a light source 10 can be provided for optical stimulation, which is attached to glasses 11 and is also controlled by the microprocessor 5 .

Ausführungsbeispiel, Siehe Fig. 1 (Ansicht) und Fig. 2 (Blockschaltbild).Embodiment, see Fig. 1 (view) and Fig. 2 (block diagram).

Im Gehäuse 1 befindet sich ein Mikroprozessor 14, der über Ausgang 6 die Leuchtdioden 16 ansteuert, die an der Brille 15 angeordnet sind. Vom Walkman 3 gelangt das Musiksignal über die Verbindung 2 in das Gerät, wird in den Modulatoren 10 und 11 in der Amplitude moduliert, und gelangt nach Verstärkung in den Verstärkern 12 an den Kopfhörer 13.In the housing 1 there is a microprocessor 14 which controls the LEDs 16 via output 6 , which are arranged on the glasses 15 . From the Walkman 3 , the music signal reaches the device via the connection 2 , is modulated in amplitude in the modulators 10 and 11 , and reaches the headphones 13 after amplification in the amplifiers 12 .
