DESCRIPTION JPH10282983
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
device for stimulating human hearing to derive a specific electroencephalogram, and in particular
to induce Fmθ by stimulating human hearing with a modulation wave. It relates to an apparatus.
[0002]
2. Description of the Related Art The potential difference observed between two different points
on the cerebral cortex and scalp is called "brain wave", and has a unique waveform, rhythm,
corresponding to the state of mind and body. Electroencephalograms are generally classified into
four waves of α wave, β wave, θ wave and δ wave according to the rhythm cycle. Among
them, the alpha wave having a period of 8 to 13 Hz appears strongly and widely continuously as
the mind and body relax. On the contrary, as the mind and body are tensed, the β wave of 18 to
30 Hz in period comes to appear strongly and widely. The θ wave with a period of 4 to 8 Hz and
the δ wave with a period less than 4 Hz are electroencephalograms related to sleep. It is said
that the θ wave appears strongly at sleep onset and the δ wave becomes dominant as the sleep
becomes deeper. As seen in Inoue et al., “They are of mental activities,” pp. 136-148 (1988),
even among the θ waves, they are observed near the mid-frontal region of adults. The dominant
θ rhythm of 6 to 7 Hz is called "Fmθ" and is said to be deeply involved in mental work. An
analysis of the brain waves of a mentally working person shows that Fmθ appears near the
frontal center of the worker, and the intensity and distribution thereof increase as the worker's
attention and concentration increase. Become strong, will appear widely.

[0003]
In this way, since Fmθ has a close relationship with attention and concentration, if Fmθ can be
artificially derived in some way, the operator's attention and concentration can be improved, and
work efficiency It is expected that the accuracy can be improved. However, until now, no device
or method has been known that can artificially induce Fmθ.
[0004]
SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention
to provide an apparatus for artificially inducing Fmθ.
[0005]
[Means for Solving the Problems] The inventors of the present invention have intensively studied
means for achieving such problems. As a result, modulation in which an extremely low frequency
of about 20 Hz or less is superimposed on a low frequency in the audible range. Stimulation of
humans through hearing by waves has been found to result in stronger, more widespread
appearance of Fmθ.
The present invention is based on such novel findings, and a modulation wave generation circuit
in which an ultra low frequency of about 20 Hz or less is superimposed on a low frequency in the
audible range, and an output terminal of the modulation wave generation circuit. According to
another aspect of the present invention, there is provided an Fmθ induction apparatus
comprising: an electroacoustic transducer connected and converting the modulated wave into an
audible stimulus.
[0006]
According to the present invention, a modulation wave formed by super-low frequencies of about
20 Hz or less superimposed on the low frequency of the audible range generated by the
modulation wave generation circuit is an audible stimulus by the electroacoustic transducer. It is
converted. The modulated wave according to the invention stimulates the appearance of Fmθ in
08-05-2019
2
its brain waves when stimulating a human through hearing. In particular, when the frequency of
the very low frequency is in the range of about 2 to 10 Hertz, not only Fmθ but also the
appearance of α wave is promoted.
[0007]
Hereinafter, the present invention will be described in detail by way of examples, experimental
examples, etc. The modulated wave in the present invention is one in which an ultra low
frequency of about 20 Hz or less is superimposed on a low frequency in an audible range. is
there. As such a low frequency, a continuous wave or a pulse wave of an appropriate waveform
whose frequency exceeds the frequency of the very low frequency and does not exceed about
20,000 hertz is usually used. As a result of various tests conducted by the inventor on healthy
subjects, when the low frequency frequency exceeds about 6,000 Hz, a part of the subject
sometimes complains of difficulty in hearing or slight discomfort. In practice, the frequency is
usually about 50 to 3,000 hertz, preferably about 100 to 500 hertz, and more preferably about
120 to 200 hertz, considering the frequency of the very low frequency and the frequency
characteristics of the electroacoustic transducer. It is good to set to. Similarly, various tests were
performed on the waveform, and it was found that continuous waves such as sine waves, pulse
waves such as sawtooth waves, square waves, triangular waves, rectangular waves, etc. and the
pulse duration is relatively long. It was suitable. On the other hand, for ultra low frequency, a
continuous wave or pulse wave with a frequency of about 20 Hz or less, usually about 2 to 10
Hz, is desirable, and its waveform is a continuous wave like a sine wave as in the low frequency
case. A relatively long pulse wave of duration is preferred.
[0008]
As described above, the modulation wave generation circuit in the present invention is an
electrical circuit that generates a modulation wave in which a specific low frequency is
superimposed on a specific low frequency. An oscillation circuit, a second oscillation circuit
generating an ultra-low frequency, and an input terminal connected to an output end of the
oscillation circuit, and modulating the low frequency with the ultra-low frequency, eg, an
amplitude modulation circuit And a modulation circuit such as a phase modulation circuit, a
frequency modulation circuit, or a pulse modulation circuit. The circuit configuration and circuit
elements in the oscillation circuit and the modulation circuit are not particularly limited as long
as the modulation wave appearing at the output end of the modulation circuit satisfies the above
requirements, but generally, a transistor, a field effect transistor and / or It is built around
integrated circuits. When the modulation circuit alone can not substantially activate the
08-05-2019

electroacoustic transducer, because the output of the modulation circuit itself is low or the
output end of the modulation circuit and the electroacoustic transducer do not match in
impedance. Does not prevent the insertion of an appropriate amplifier or matching circuit
between the modulation circuit and the electroacoustic transducer. Such embodiments are, of
course, also intended to be encompassed by the present invention.
[0009]
In another aspect of the modulation wave generation circuit, the modulation wave generation
circuit is constituted by a reproduction circuit and, if necessary, an amplification circuit, and the
modulation wave recorded on a magnetic or optical recording medium by the reproduction
circuit is After reproduction, the reproduction output may be amplified as necessary and then
supplied to the electroacoustic transducer. Examples of the magnetic recording medium include a
magnetic tape, a magnetic disk, and a magnetic floppy, and examples of the optical recording
medium include an optical disk. More specifically, for example, the modulation wave is recorded
on a general audio tape, a compact disc or the like, and this is reproduced by a general
reproduction apparatus and made to be heard by a target person. According to such an aspect, it
is extremely convenient because a home audio video device can be used as it is.
[0010]
By the way, when the present inventors focused on the induction ability and the side effect of
Fmθ, various tests were performed on the modulation degree of the modulation wave for
healthy subjects, and it is about 30 to 100%, preferably about 70 to When in the range of 90%, it
was possible to induce the highest level of Fmθ without substantially causing side effects such
as discomfort. Therefore, it is desirable to set the output of the oscillator circuit or the like so that
the low frequency modulation degree due to the ultra low frequency is in this range, or to adjust
the modulation circuit to be in this range. Since the low frequency modulation degree due to the
very low frequency and the optimum frequency for the low frequency and the very low
frequency are usually slightly different depending on the individual subjects, each individual
subject has an optimum modulation degree or frequency. It is desirable to provide the oscillation
circuit and / or the modulation circuit with a function capable of adjusting the degree of
modulation or frequency within a certain range so as to receive an audio stimulus.
[0011]
08-05-2019

The audible stimulus according to the present invention significantly enhances the Fmθ
induction ability by adding so-called “1 / f fluctuation”. That is, when the appearance
frequency, duration, frequency and / or intensity of the audible stimulus are varied according to
the 1 / f fluctuation rule, the audible stimulation based on the modulation wave and the variation
due to the 1 / f fluctuation rule act synergistically. It has been found that it promotes the
appearance of Fmθ to an extent that can not be easily achieved by either one or the other. In
particular, a series having 1 / f fluctuation sampled from long-term fluctuations of biological
phenomena such as electroencephalogram, heart rate, blood pressure, respiration, and body
temperature is extremely useful, and the frequency of occurrence of an audible stimulus based
on such a series. When varying in duration, frequency and / or intensity, only a small amount of
stimulation can induce very high levels of Fmθ, which also last for a long time after stimulation.
This is because a series having 1 / f fluctuation sampled from long-term fluctuation in human
biological phenomena contains much important information on biological control mechanisms
represented by the nervous system, and the information is It is understood that it is effective in
promoting the appearance of Fmθ effectively as well as synergistically enhancing the
physiological action of the audible stimulus according to the present invention. In order to apply
such a variation to an audible stimulus, for example, a sequence as described above is stored in a
microprocessor, and an electrical signal including a pseudo 1 / f fluctuation sequence extracted
therefrom is turned on / off through an interface. It may be derived to a circuit, and the on / off
circuit may perform conduction control of the oscillation circuit and the modulation circuit.
[0012]
The modulated wave obtained as described above is supplied to the electroacoustic transducer
where it is converted into an audible stimulus. In the present invention, an audible stimulus
means a stimulus that human beings can perceive by an auditory organ, and usually means a
stimulus by an acoustic wave. Therefore, the electroacoustic transducer in the present invention
is means for converting the modulated wave electrically generated as described above into a
sound wave. The individual electroacoustic transducers include, for example, electromagnetic
transducers such as electrokinetic speakers and electromagnetic speakers, electrostatic
loudspeakers, electrostatic transducers such as piezoelectric loudspeakers, or a combination
thereof. . The operating principle, shape, shape and size of the transducer are not particularly
limited, and any one can be used in the present invention as long as the user can perceive the
modulated wave through his / her hearing. When carrying and using the device of the present
invention, small headphones and earphones are preferred.
[0013]

The method of supplying the modulation wave generated by the modulation wave generation
circuit to the electroacoustic transducer is roughly classified into two types, one of which is a
cable of the modulation wave generation circuit and the electroacoustic transducer It is a wired
method of direct connection by the like. In this method, usually, the subject or his / her assistant
manipulates an electrical component including a modulated wave generation circuit at a place
where the subject actually listens. Another method is to separately configure an electrical
component including a modulation wave generation circuit and an electrical component
including an electroacoustic transducer, and output the modulation wave generation circuit using
the latter by wireless communication or optical communication. It is a wireless system that
supplies electrical components. In the wireless method, the assistant usually operates the former
electrical component at a place slightly away from the place where the subject actually listens.
Although there is no substantial difference in adopting any of the methods in terms of inducing
Fmθ, in the case of the latter method, it becomes easy to stimulate a plurality of subjects at the
same time, and wireless Within the reach of the above, there is an advantage that the subject can
move freely.
[0014]
The use of the device according to the invention will now be described, depending on the
purpose of use, but in general the audible stimulation by the device according to the invention
may at first be somewhat strong and gradually diminish. When the purpose of use is to improve
attention and concentration during mental work, stimulation may be performed before or during
each operation for an appropriate time each time as needed. For the purpose of prevention and
treatment of diseases etc., while observing the condition of the subject carefully, for example,
weekly up to about 2 hours as a maximum stimulation time per one time 1 to 3 times a day It
may be continued for one to seven days, one month to one year. Depending on the purpose of
use and the subject, the sound pressure of the audible stimulus at that time is usually about 20 to
90 dB, preferably about 30 to 80 dB. The auditory stimuli according to the invention usually
have no substantial difference in Fmθ inducibility, whether they are heard from only one ear or
both ears. When it is necessary to keep hearing the audible stimulus of the present invention for
a long time, for example, only one ear may be audibly stimulated, or a switch may be inserted
between the oscillation circuit and the electroacoustic transducer. By operating the switch, one
ear may be made to hear a modulated wave, and the other ear may be made to hear an
unmodulated low frequency. Although depending on the subject, the audible stimulus by the
device of the present invention has the property of prompting the appearance of Fmθ even if
listening to it for a long period of time, after that it listens for a very short time or without
listening at all. For such a subject, the device of the present invention is useful as a so-called

"mental training" means. In addition, the device of the present invention is provided with an
electroacoustic transducer, for example, a radio receiver, a television receiver, a record player, an
audio tape player, a compact disc player, a mini disc player, a video disc player When
incorporated into an apparatus, an audio / video apparatus such as a video disk reproduction
apparatus, a multimedia personal computer, etc., it is possible to listen to the audio stimulus
according to the present invention and the music simultaneously or at any time by one
apparatus.
[0015]
Hereinafter, the present invention will be more specifically described by way of illustrated
examples and experimental examples.
[0016]
FIG. 1 is a block diagram of electrical components in an embodiment according to the present
invention.
In the figure, O1 and O2 are respectively a first oscillation circuit or a second oscillation circuit,
and usually an operational amplifier is used. The first oscillator circuit O1 generates a sine wave
having a frequency of about 150 Hertz, and the second oscillator circuit O2 generates an ultra
low frequency having a sine wave waveform of a frequency of about 2 to 10 Hertz. The second
oscillation circuit O2 is provided with a variable resistor V1, and by operating this, the frequency
of the very low frequency can be changed in the range of about 2 to 10 Hertz. M is a modulation
circuit, and the output ends of the first oscillation circuit O1 and the second oscillation circuit O2
are connected to the input end thereof, and the low frequency and the ultra low frequency are
amplitude modulated here, and the output thereof At the end, a modulation wave in which an
ultra low frequency is superimposed on a low frequency is derived. The variable resistor V2
provided in the modulation circuit M is for adjusting the depth of the amplitude modulation, and
by operating this, the modulation degree can be changed in the range of about 30 to 100%. The
output terminal of the first oscillator circuit O1 is connected to the input terminal of the first
amplifier circuit A1 via the switch S, and the output terminal of the modulation circuit M is
connected to the input terminal of the second amplifier circuit A2 and the switch S It is
connected to the contact b. A headphone P as an electroacoustic transducer is connected to an
output end of the first and second amplification circuits A1 and A2 through a disconnectable
connector C. The variable resistors V3 respectively provided at the input ends of the pair of
amplifiers A1 and A2 change the magnitudes of the electric signals applied to the amplifiers A1
and A2 so that the audio stimulation radiated from the left and right speaker units in the
08-05-2019
7
headphones P can be generated. To adjust the size of the A variable resistor V4 provided across
the input terminals of the pair of amplifiers A1 and A2 radiates radiation from the left and right
speaker units in the headphone P by adjusting the magnitude of the electric signal applied to the
amplifiers A1 and A2. To balance the audible stimuli that are being
[0017]
In the operation of this example, when the circuit is started with the switch S at the position of
the contact b, the outputs of the first and second oscillation circuits O1 and O2 are supplied to
the modulation circuit M. The two outputs are mixed here and amplitude-modulated to derive at
the output end of the modulation circuit M a modulated wave having a waveform as shown in
FIG. As seen in FIG. 2, on this modulation wave, a sine wave having a frequency of about 2 to 10
hertz is superimposed on a sine wave having a frequency of about 150 hertz. The output of the
modulation circuit M is amplified by the amplifiers A1 and A2 to energize the pair of speaker
units in the headphone P. When the changeover switch S is connected to the contact a, the
modulation wave is supplied only to the amplifier A2, and the amplifier A1 is supplied with a low
frequency of about 150 Hz generated by the first oscillation circuit O1. In this case, a modulated
wave is radiated from one of the speaker units in the headphone P, and a non-modulated sine
wave is radiated from the other speaker unit.
[0018]
Since this example is thus configured, when the subject operates with the headphone P on his
head, a sine wave having a frequency of about 150 Hz may be applied to the subject's ear or a
frequency of about 2 for the sine wave. It is possible to hear a modulation wave formed by
superposing sine waves of 10 Hz to 10 Hz.
[0019]
Embodiment 2 FIG. 3 is a block diagram showing the electrical components of another
embodiment according to the present invention for supplying the output of the modulation wave
generation circuit to the electroacoustic transducer in a wireless manner.
The reference symbols O1, O2, M, V1 to V4, P and C in the figure are for referring to the same
circuit or circuit element as in the embodiment shown in FIG. It is substantially the same.
08-05-2019

[0020]
As shown in FIG. 3, this example comprises a transmission system and a reception system. In the
transmission system, the modulation wave or sine wave generated by the first oscillation circuit
O1, the second oscillation circuit O2 and the modulation circuit M is subjected to stereo
frequency modulation via the changeover switch S as in the previous embodiment. It is supplied
to the input of the circuit FSM. The frequency modulation circuit FSM usually has a low
frequency amplification circuit for amplifying a modulation wave or a sine wave applied to the
input end, and an input end connected to the output end of the low frequency amplification
circuit. It is configured by a frequency modulation circuit or the like that converts into a high
frequency frequency-modulated based on a modulation wave or a sine wave. The output end of
the frequency modulation circuit FSM is connected to the input end of the high frequency power
amplification circuit RFP for appropriately amplifying the high frequency, and the output end of
the high frequency power amplification circuit RFP is an antenna ANT1 for radiating the high
frequency. It is connected. The receiving system includes an antenna ANT2 for receiving a high
frequency, a stereo type receiving circuit FSR that demodulates the high frequency voltage from
the antenna ANT2 into an electric signal including an original modulation wave or a sine wave,
and an output of the receiving circuit FSR. It comprises a headphone P as an electroacoustic
transducer which converts it into an audible stimulus.
[0021]
The operation of this example will be described. Since this example is configured as described
above, when the reception system is started with the transmission system operating, a pair of
speaker units in the headphone P is a sine wave having a frequency of about 150 Hz.
Alternatively, a modulation wave in which a sine wave having a frequency of about 2 to 10 Hz is
superimposed on this sine wave is radiated.
[0022]
Since this example is thus configured, one or more receiving systems are provided for one
transmitting system, and the individual receiving persons carry this receiving system and the
headphone P is worn on the head. If you operate this properly, you can hear the modulated wave.
This example is useful for stimulating a plurality of subjects simultaneously in a relatively wide
08-05-2019

area.
[0023]
Next, the operational effects of the present invention will be specifically described by way of
experimental examples.
[0024]
[Experimental example] Five subjects each in the 20-year-old male and female with no
neuropsychiatric disorder were used as subjects, and in addition to stereo headphones on their
heads, biological electrodes for electroencephalogram measurement were attached according to
the International Standard EEG Association Standard Electrode Placement Method. did.
An electroencephalograph “1A97A type” manufactured and sold by NEC San-ei Co., Ltd.
equipped with a data processing device for a biomedical electrode for electroencephalogram
measurement, and a stereo headphone with a slightly expanded frequency range of ultra low
frequency, except for the embodiment The apparatus produced similarly to 2 was connected.
Next, first, in a state in which the subject is not audibly stimulated, 15-minute loading of the
Creperine test (continuous first place addition work) as mental work is performed, and during
that time the subject's brain wave is detected and amplified. Recorded on the data recorder "XR710" manufactured and sold by the company. After completing the first half of the test, the
subject is rested for 5 minutes, and this time, while listening to the audio stimulus, load the
Kraepelin test for the last 15 minutes while detecting the subject's brain waves in the same
manner as described above. The obtained data was amplified and then recorded on a data
recorder. The sound pressure of the audible stimulus was set to about 70 dB on the tympanic
membrane of the subject.
[0025]
After completion of the test, the data recorded in the data recorder is subjected to addition
processing nine times using a signal processor “7T18A type” manufactured and sold by NEC
Sanei Co., Ltd., and frequency analysis is performed, and Fmθ of 10 test subjects is averaged.
Displayed as topographs per minute. In addition, during mental work for 15 minutes each in the
first half and the second half, Fmθ derived from F3, Fz and F4 sites in the subject's head is
averaged per minute for each of the first 15 minutes and the second half Volts were determined,
08-05-2019
10
and the average intensity obtained was substituted into Equation 1 for each part to calculate the
Fmθ increase rate (%). These topographs and Fmθ increase rate were used as a standard for
judging the Fmθ induction ability of each audible stimulus. The results are shown in Table 1,
FIG. 4 and FIG.
[0026]
As a control, a system which can not hear any audible stimulus (hereinafter referred to as
"control 1"). And a non-modulated wave, that is, a system in which only a sine wave having a
frequency of about 150 Hz is heard (hereinafter referred to as "control 2" These controls were
also tested in the same manner as described above.
[0027]
As apparent from the results of Table 1, a remarkable difference was observed in the rate of
increase in Fmθ, although all the audible stimuli contained a sine wave with a frequency of 150
Hz in common. That is, when the frequency of the very low frequency is in the range of about 20
Hz or less, the Fmθ increase rate is significantly increased in all the regions of F3, Fz and F4,
and depending on the derivation region, about 130% of Control 1 It also reached. The topographs
of FIG. 4 and FIG. 5 also support the fact that Fmθ appears strongly and widely in the center of
the frontal midline of the subject when mental work is performed with audible stimulation by the
modulated wave according to the present invention. . As seen in the results of Control 3 and
Control 4 in Table 1, when the frequency of the extremely low frequency exceeds 20 Hz, no
significant difference in Fmθ increase rate is found between Control 1 and Control 2, and the
subject Some have complained of minor discomfort or diminished concentration, and there have
been cases where there has been a clear delay in the progress of the Klepelin test.
[0028]
From the above experimental facts, it is understood that a frequency of about 20 hertz or less, in
particular, in the range of about 2 to 10 hertz is suitable as the very low frequency. Although the
data is not shown, when the frequency of the low frequency is fixed in the range of 50 to 6,000
Hz while the frequency of the very low frequency is fixed at around 8 Hz, the same test is
performed. The increase in Fmθ increased significantly when the frequency was about 100 to
500 Hertz and peaked at about 120 to 200 Hertz. In addition, a modulation wave formed by
08-05-2019
11
superimposing a sine wave having a frequency of about 8 hertz on a sine wave having a
frequency of about 150 hertz was tested in the same manner while changing the degree of
modulation appropriately, and the degree of modulation was about 30 to 100%. , The Fmθ
increase rate reached a peak. In addition to sine waves, we also tested pulse waves such as
sawtooth waves, square waves, triangle waves, and square waves. Although the pulse with a
relatively long duration is slightly inferior to a sine wave, almost the same results are obtained. It
was done.
[0029]
Separately, the effect of the audible stimulus according to the present invention on the
appearance of the alpha wave was tested on the above 10 subjects. That is, the head of the
subject is equipped with a bioelectric electrode for measuring an electroencephalogram and
stereo headphones, relaxed as much as possible, and in a closed position for 60 minutes, a sine
wave of about 150 Hz and a sine wave of 8 Hz The audio was stimulated by the superimposed
modulation wave. During that time, the brain waves were detected and amplified by a
conventional method, and then recorded on a data recorder. At the end of the test, the recorded
data were frequency analyzed, and an alpha wave of 8 to 10 Hz was displayed for 20 minutes
immediately after the start of measurement, and was displayed as topographs per minute at 5minute intervals. Three days later, the same subject was subjected to exactly the same
experiment except that the audible stimulation by the modulated wave was omitted. As a result,
upon audible stimulation with the modulated wave according to the present invention, a
remarkable change appears in the alpha wave of the subject, and the alpha wave without audible
stimulation is as seen in FIG. As shown in FIG. 7 when stimulating by audio, as shown in FIG. 7, it
was observed that the alpha wave was strong and appeared extremely widely around the top of
the subject's head 15 minutes after the start of the audio stimulation. At the same time, the
appearance of the beta wave was also significantly suppressed. This tendency did not change
substantially even if the frequency of the very low frequency was changed in the range of about
2 to 10 Hertz.
[0030]
These facts suggest that the audible stimulus according to the present invention not only
stimulates the appearance of Fmθ but also acts to suppress the appearance of β wave while
promoting the appearance of α wave. As described above, since the alpha wave and the beta
wave are brain waves corresponding to relaxation or tension of the mind and body respectively,
the device of the present invention induces Fmθ to enhance attention and concentration when
08-05-2019
12
used with an eye open and close the eye If it is used as it is, it induces α wave and suppresses β
wave to relax mind and body.
[0031]
As mentioned above, since Fmθ is a good indicator of attention and concentration, the result of
this experiment is that the device of the present invention is used in mental work in general to
enhance the user's attention and concentration, and mental work It can be said that it suggests
keeping the efficiency and accuracy of And this is also covered by the progress rate (%) of the
Creperine test, and as shown in Table 1, the progress rate (%) of the work is significantly
increased in the case of audible stimulation with the modulation wave according to the present
invention It was
[0032]
As the device of the present invention is thus configured, its modulated wave stimulates the
appearance of Fmθ in its brain waves when it stimulates a human through hearing. In particular,
when the very low frequency is in the range of about 2 to 10 Hertz, it promotes not only Fmθ
but also the appearance of an α wave. Therefore, when the modulated wave according to the
present invention stimulates a human body through hearing, it promotes a desired state of mind
and body involving Fmθ and α waves, that is, an improvement in attention and concentration,
and relaxation and rest.
[0033]
Therefore, the device of the present invention is not limited to improvement in attention and
concentration, relaxation of mind and body, relaxation, learning ability, improvement of
creativity, and further, for example, neurose, mental weakness, etc. Stress disorders, including socalled technostress, due to psychiatric disorders such as psychosomatic disorder, depressive
disorder, chronic alcoholism etc. and electromagnetic waves radiated from eg TV sets, video
displays, OA equipment, car spark plugs etc. It is effective in reducing or alleviating general
thinking power, concentration power, decline in work motivation, insomnia, malaise, intimidation,
phobia, feeling of insufficiency, etc. Therefore, the device according to the present invention can
be used in general homes, workplaces, stadiums, schools, learning schools, training schools,
training centers, research institutes, ateliers, etc., with efficiency and accuracy of mental work,
08-05-2019
13
learning ability, academic research ability, creativity Alternatively, it is useful as a means for
enhancing concentration during competition, and also as a means for preventing and treating
various mental diseases including stress in workplaces, clinics, hospitals, nursing homes and the
like. Depending on the subject, when listening to the audible stimulus according to the present
invention for a long time, the appearance of Fmθ may be promoted even if the user listens for a
very short time or not at all. For such a subject, the device of the present invention is also useful
as a means of so-called "mental training".
[0034]
Thus, it can be said that this invention is truly a significant and significant invention that
contributes to the field.
