【発明の詳細な説明】 ＜産業上の利用分野＞ 本発明は、人の頭部を音響刺激することにより、脳波の
周波数低下を誘導する装置に関する。Description: TECHNICAL FIELD The present invention relates to a device for inducing a decrease in the frequency of brain waves by acoustically stimulating the human head.
＜従来の技術＞ 人の脳波は、心身が緊張するとβ波（18乃至30ヘルツ）

眼すると、α波（８乃至13ヘルツ）が連続的に出現する
ようになる。<Prior Art> Human brain waves are β waves (18 to 30 Hertz) when the mind and body are tense.
Is strong and appears in a wide area, and conversely, when the mind and body are rested and the eyes are closed, α waves (8 to 13 hertz) appear continuously.

作活動や学習が可能になることを示唆している。しかし
ながら、実際には、脳波が心身の状態と密接に関連して
いることから、外部刺激などにより脳波の周波数を低下
させ、α波の出現を促すことは容易ではなかった。It is said that people usually exert their creativity and improve their learning ability when α waves predominantly appear.
This suggests that artificially inducing α-waves enables efficient research and creative activities and learning. However, in reality, since the electroencephalogram is closely related to the state of mind and body, it was not easy to lower the frequency of the electroencephalogram by external stimulation or the like to promote the appearance of the α wave.
一方、錯綜した現代社会にあっては、いろいろな精神的
ストレスが増大しており、これらストレスを蓄積させる
ことなく、早期に解消・発散させる手段が必要になって
きている。On the other hand, in a complicated modern society, various mental stresses are increasing, and it is necessary to provide a means for eliminating and diverging these stresses early without accumulating these stresses.

与するのがより効果的であることが判ってきた。As a method of relieving stress, a static method of suppressing the sympathetic nerve by bathing, sleeping, resting, etc. and promoting the sympathetic nerve is generally performed. Recently, even in the static method, it has been found that it is more effective to apply a stimulus such as sound or vibration to the human body to a comfortable level rather than completely blocking the stimulus.

とにより、その安静乃至入眠を誘導する提案がなされて
いる。In such a situation, various proposals have been made so far to lower the frequency of brain waves by stimulating the human head acoustically to promote the appearance of α waves. For example,
Japanese Unexamined Patent Publication No. 50-143377 proposes to induce an α-wave by amplifying an electroencephalogram collected from a subject by an electric circuit means and then allowing the subject to listen through a speaker or the like. On the other hand, in Japanese Unexamined Patent Publication No. 51-11693, electric vibration with a frequency of 40 to 800 Hertz is 1 to 7/3.
After amplitude modulation in the range of Hertz and amplification of the obtained modulated wave,
It has been proposed to induce rest and sleep by converting the sound into a sound by an electroacoustic transducer and administering the sound to a newborn baby.
ところが、両提案は、いずれも、α波の出現を促す能力

で変調しただけの変調音は、長時間聴かせたり、反復し
て聴かせると、音刺激に対する一種の「なれ」が生じて
しまい、その後は、変調音自体が有効な刺激たり得なく
なるという問題がある。However, neither of these proposals has a problem in that the ability to promote the appearance of α waves is not sufficient, and thus they have not yet been put into practical use. That is, in the former proposal, a human alpha wave has a frequency of about 8
It has an extremely low frequency of 13 to 13 Hz, and there is a problem that it cannot be easily converted into sound by an ordinary electroacoustic transducer such as a speaker. Moreover, even if it is converted into sound, such an ultra-low frequency is below the audible lower limit of an ordinary person, and there is a problem that it is difficult for the target person to perceive it as sound. The latter proposal is relatively easy to convert into sound, but has a problem that the effect when administered to humans, especially the effect on adults is not sufficient. In addition, the modulated sound obtained by modulating the low frequency in the audible range with a specific ultra-low frequency causes a kind of "naiveness" to the sound stimulus if it is played for a long time or if it is played repeatedly. Has a problem that the modulated sound itself cannot be an effective stimulus.

Then, the audible sound, when administered to the head of the subject, effectively induces a decrease in the frequency of the electroencephalogram and suppresses the β-wave component in the electroencephalogram, while α
The wave component is increased and its continuity is improved to effectively relax the mind and body of the subject. In addition, the modulated sound according to the present invention forms a sound image that reciprocates between the ears of the subject in a constant cycle depending on the intensity of the sound, so that it can be administered to the subject for a long period of time or for a long period of time. Even if repeated administration is carried out, there is a characteristic that it is difficult for the "stimulus" to occur to the sound stimulation.
