By activating in parallel, it becomes possible to express or intensify both sensitization and comfort of sound perception in a compatible state.
- the first effect is an effect of making the sensitivity to sensory information input sharper and more clearly recognizing sensory information such as sound by enhancing the activity of the thalamus and brainstem included in the backbone brain network system of the listener.
- That is, a condition that presents a vibration (hypersonic sound) capable of inducing a fundamental brain activation effect because it contains an ultrahigh frequency component having a predetermined autocorrelation order in the library;
- Three conditions were set for the day: conditions for presenting vibration (audible sound) that can not lead to the activation effect, and conditions for not presenting a special sound.

Moreover, there is a tendency to gradually increase the volume as the number of times is increased. As a result, it can be understood that in the hypersonic sound, the sense of comfort is higher and a larger volume is selected, while in the audible sound, the sense of discomfort is higher and the volume is set smaller. The above shows that by presenting the hypersonic sound, the listener's comfort can be enhanced even for high-volume vibration input.

- the announcement sound and the broadcast sound that are flowed in the station yard need to ensure that the information is transmitted to the user, and therefore, it is necessary to secure the necessary volume.
- the loud sound must be exposed to the user at a high volume. The problem is that it inevitably causes discomfort such as "noisy”.

- This decrease in core brain activity leads to a stress response such as an increase in adrenaline concentration, which intensifies discomfort such as "noisy" and leads to frustrated emotions.
- the necessary information can not be effectively transmitted, but also there is a serious problem that the risk of triggering an act of violence or abnormal behavior increases.
- hypersonic sound or its superhigh frequency component is complemented to the transmitted sound (audible sound).
- the vibration to be complemented may be a hypersonic sound itself that does not hinder the transmission of necessary information, such as, for example, a tropical rain forest environmental sound, or even the superhigh frequency component of those hypersonic sounds. Good.

- a reward system neural circuit of the brain which belongs to a basic brain network system and controls generation of pleasure, beauty and emotion in human being, is also activated in parallel and inputted by the user.
- the aesthetic sensitivity to sensory information is increased, so that the sense of comfort can be enhanced even for loud transmitted sound (audible sound), and discomfort such as "noisy” and irritability can be alleviated.

図22及~図28は、障害物に衝突させながら液体を流すことによって、可聴域成分及び超高周波成分を含むとともに所定の自己相関秩序を有し、基幹脳活性化効果を導くことができる振動(ハイパーソニック・サウンド)を発生する振動発生装置の例である。水音は、図1、図4、図8及び図10に示したように、可聴域成分と超高周波成分並びに自己相関秩序に関する第1の性質と第2の性質とをあわせもち、基幹脳活性化効果を導くことができる振動である。下記装置例では、水流をはじめとする液流を設定された障害物に衝突させることにより、所定の自己相関秩序を有する超高周波成分を含む振動を発生させる。このようにして可聴域成分及び超高周波成分を含むとともに所定の自己相関秩序の特徴をもつ振動(ハイパーソニック・サウンド)を発生することにより、人間における快と美と感動の反応の発生を司る脳の報酬系神経回路と、全身の恒常性維持と生体防御を司る自律神経系、内分泌系、免疫系の中枢とを含む基幹脳並びに基幹脳ネットワーク(基幹脳ネットワーク系)の活性化を導き、その結果、美的感受性を増強し、身体の状態を改善向上する効果が得られる。
この問題の解決方法として、スピーカ・システムそれ自体に独立した振動発生機能を与え、何らかの機器に接続するだけで、あるいは単独で、ハイパーソニック・サウンドもしくはその超高周波成分の振動を発生する機能をもたせる。
A-(1)携帯電話機410に振動発生機能を内蔵し、携帯電話機410(筐体412、液晶画面、操作ボタン等)を振動させることによって、所定の自己相関秩序をもつ超高周波成分を含む振動を発生させ、直接あるいは空気振動を介して人間に印加する。

図57は本実施形態に係る、人間を取り囲む物体である空気を超高周波帯域で振動させることにより導かれた所定の自己相関秩序の特徴を満たす振動状態にある振動体の例を示す側面図である。図57において、椅子562に座った聴取者563を取り囲む空間内に、例えばピアノ等の音源561の音などのように可聴域をこえる超高周波成分をほとんど含まない振動が発生した場合、本来ならば基幹脳活性化効果が導かれることはないが、超高周波帯域(聴こえない)で振動状態にある空気が存在することが決定的な要因となって、基幹脳活性化効果を導くことができる。ここで振動体は、空気以外の気体、液体又は固体でもよい。
本発明に係る第2の実施形態では、基幹脳活性化効果を導かないオリジナル振動信号に対して、基幹脳活性化効果を導くことのできる振動信号を加える振動補完装置を含む振動発生装置及び方法について以下に説明する。

[数2]

=a1x(t-1)+a2x(t-2)+…+amx(t-m)
と実測値x(t)の差の分散であり、一般に予測誤差の分散と呼ばれる。
(2)AD変換器673から出力された基幹脳活性化効果を導かない振動信号は、次にアクティブプロセッシング回路675に入力される。信号の時系列データを、長さTE秒間の単位区間に分割し、i番目の区間の時系列データを
[数3]
yi(t)(i=1,2,…,n;t=1,2,…,2fN×TE)
とする。
(3)自己相関係数演算器676から、次項に述べる自己相関係数コントローラ675bを経由して、畳み込み演算器675aに自己相関係数が入力される。入力される自己相関係数ai1,ai2,…,aimと、入力信号yi(t)との間で次式の畳み込み演算が行われる。
[数4]
zi(t)
=ai1yi(t-1)+ai2yi(t-2)+…+aimyi(t-m)
ここで、zi(t)は畳み込み演算によって得られる出力信号であり、上述の自己相関秩序に関する性質をもち、基幹脳活性化効果を導くことができる振動信号となっている。
(2-1)単純反復:自己相関係数マトリクスAの1行目にもどり、もう一度、1行目の自己相関係数から順に畳み込み演算器675aに入力する。自己相関係数マトリクスAの最終行(n行目)になった時点で、まだ基幹脳活性化効果を導かない振動信号の入力が継続している場合、もう一度、同じ動作を行う。このようにして、基幹脳活性化効果を導かない振動信号が終わるまで反復を続ける。
(2-2)ランダムな順序で行を置換したマトリクス:マトリクスAの1行~n行の各行をランダムな順序で置換したマトリクスBを生成する。生成されたマトリクスBの1行目の自己相関係数から順に畳み込み演算器に入力する。自己相関係数マトリクスBの最終行(n行目)になった時点で、まだ基幹脳活性化効果を導かない振動信号が継続している場合、もう一度、マトリクスAの1行~n行の各行をランダムな順序で置換し、別のマトリクスB’を生成する。生成されたマトリクスB’の1行目の自己相関係数から順に畳み込み演算器675aに入力する。このようにして、基幹脳活性化効果を導かない振動信号の入力が終わるまで同様の操作を続ける。なお、上記の手順例では、行をランダムな順序で置換する例を示したが、例えば行を逆順に置換したり、奇数行を前半に、偶数行を後半に置換するなど、なんらかの規則に従って置換してもよい。
(2-3)列を反転させた折り返し自己相関係数マトリクス:自己相関係数マトリクスAのすべての行ベクトルについて、m次の自己相関係数ai1,ai2,…,aimを、逆の順序、すなわちai1,ai2,…,aimに並べ替えることにより、列の順序を反転させた折り返し、次式の自己相関係数マトリクスRevAを作成する。
[数5]
RevA(i,k)=A(i,m-k+1),
(i=1,2,…,n;k=1,2,…,m)
また、(2-1)~(2-3)の操作を組み合わせて行ってもよい。

本発明に係る第3の実施形態では、複数の感覚系に総合的に働きかける複合感覚情報手段を提供する。当該手段においては、各種感覚情報における記録・伝送可能な情報容量や情報伝達速度に制約が生じやすいために、互いに異なる感覚情報の間で利用できる情報量がトレードオフの状態に陥り、一部の感覚情報にデータ節約をしわよせした結果、その感覚情報のもつ表現効果が低下したり、互いを活かそうとして共倒れに陥ることを避ける、という課題を解決するための手段である。この課題を解決する手段の背景として、本発明者らは、人間におけるすべての快と美と感動の反応の発生が、脳の報酬系神経回路によって一元的かつ包括的に司られている実態、及びその報酬系神経回路が基幹脳及び基幹脳ネットワークに含まれており活性が基幹脳全体の活性と同一化している事実、さらにこの基幹脳及び基幹脳ネットワークがハイパーソニック・サウンドによって活性化される現象に注目した。これらに基づいて検討を行い、本発明者らは、詳細後述するように、複合感覚情報の中に含まれる音情報に適切な構造をもたせることによってハイパーソニック・エフェクトを導き、受容者の快と美と感動の反応の発生を一元的包括的に司る脳の報酬系神経回路を含む基幹脳並びに基幹脳ネットワーク(基幹脳ネットワーク系)を活性化すると、音に対する美的感受性が増強するのと並行して、聴覚以外からの各種の感覚情報入力に対してもその美的感受性が増強され、快さ、美しさ、感動を高める効果を現すという現象を発見し、これを応用する着想を得た。
音は、「Blu-ray Disc版AKIRAサウンドトラック」のために編集されたものである。これまでのAKIRAサウンドトラックは、振動信号が標本化周波数48kHz、量子化ビット数16ビットのデジタルフォーマットでDVDに記録されていたため、標本化周波数の2分の1であるナイキスト周波数24kHz以上の帯域成分を記録することも再生することもできず、従って基幹脳活性化効果を導くことができない。そこで、「DVD版 AKIRAサウンドトラック」用の音声信号をオリジナル振動とし、その信号を帯域伸張するとともに、図66に示した振動補完装置を含む振動信号発生装置を用いて、基幹脳活性化効果を導くことのできる典型的な振動である熱帯雨林環境音や、そこから抽出した可聴域上限をこえる超高周波成分などを加算して出力信号を合成し、それをブルーレイディスクにサンプリング周波数192kHz、量子化ビット数24ビットのデジタルフォーマットで記録することにより、「Blu-ray Disc版 AKIRAサウンドトラック」の振動信号を作成し、ブルーレイディスクに記録した。この音は、図78~図81に示したように、超高周波成分を十分含むとともに、自己相関秩序の2つの性質を有し、基幹脳活性化効果を導くことができる音となっている。
次いで、第4の実施形態では、第1から第3の実施形態で述べてきた振動発生装置を応用して、基幹脳ネットワーク系全体の活動を高めることによって、感覚の鋭敏化と快適化という2つの効果を両立した状態で発現又は強化させることを特徴とする振動発生装置及び方法について述べる。
(2)図109に示すように、伝達音(可聴音)とハイパーソニック・サウンドもしくはその超高周波成分とを、異なる音源によって異なる拡声装置472,472を用いて発生させる。この場合は、伝達音(可聴音)及びハイパーソニック・サウンドもしくはその超高周波成分のそれぞれについて、独立にレベル制御を行うことができる。ここで、振動補完装置は、
(a)伝達音(可聴音)を収集するマイクロホン473と、振動信号増幅器471と、拡声装置472とを含む第1の装置と、
(b)ハイパーソニック・サウンドもしくはその超高周波成分を記録した記録媒体470dを用いて振動信号を再生する振動信号再生装置470と、振動信号増幅器471と、拡声装置472とを含む第2の装置とを備えて構成される。
(3)上記(2)の変形例であり、図110に示すように、伝達音(可聴音)とハイパーソニック・サウンドもしくはその超高周波成分をその場で合成し、ひとつの拡声装置472から発生させる。振動補完装置は、伝達音(可聴音)を収集するマイクロホン473と、ハイパーソニック・サウンドもしくはその超高周波成分を記録した記録媒体470dを用いて振動信号を再生する振動信号再生装置470と、振動信号加算調整器474と、振動信号増幅器471と、拡声装置472とを備えて構成される。振動信号加算調整器474は入力される2つの信号の各レベルを調整かつこれら2つの信号を加算して振動信号増幅器471を介して拡声装置472に出力する。
(4)上記(3)にさらに調整機能を付加した例である。図111に示すように、背景雑音(可聴音)をマイクロホン475で収集し、収集した振動信号に基づいて振動計測器476により背景雑音(可聴音)の特徴を計測し、計測したデータを振動信号加算調整器474に入力する。その他の構成は上記(3)の場合の構成を含む。振動信号加算調整器474は、背景雑音(可聴音)の特徴に合わせて、伝達音(可聴音)及びハイパーソニック・サウンドもしくはその超高周波成分を調整する機能をもつ。調整機能の例として、例えば、背景雑音(可聴音)の騒音レベルが一定の値を超えたらハイパーソニック・サウンドもしくはその超高周波成分をオンにする機能、あるいは、背景雑音(可聴音)の騒音レベルに相関した増幅率で伝達音(可聴音)並びにハイパーソニック・サウンドもしくはその超高周波成分のレベルを増幅する機能、あるいは、背景雑音(可聴音)の自己相関秩序の特徴を解析してその特徴に基づいてハイパーソニック・サウンドもしくはその超高周波成分の自己相関秩序の特徴を強調又は抑制する機能などがある。
(1)パッケージメディアの中にあらかじめ可聴音とハイパーソニック・サウンドもしくはその超高周波成分のバランスを決めて作り込む。

(3)上記(2)の変形例であり、可聴音とハイパーソニック・サウンドもしくはその超高周波成分をその場で合成し、ひとつの振動発生装置から発生させる。
本発明に係る振動判別装置及び方法は、与えられた振動信号が、人間が音として知覚できる可聴周波数範囲である20Hzから15kHz乃至20kHzまでの範囲内の成分(可聴域成分)を有する振動であるとともに上記可聴周波数範囲をこえ例えば1MHzまでの範囲内の超高周波成分を有しているか否かを判別し、与えられた振動信号が上記第1の性質で表される自己相関秩序を有しているか否かを判別し、与えられた振動信号が上記第2の性質で表される自己相関秩序を有しているか否かを判別し、上記の三つの手段による判別結果を総合することにより、与えられた振動が上記振動信号の特徴を有するかどうかを判別することを特徴としている。
以下、自己相関秩序に関する第1の性質及び第2の性質を導く計算式について説明する。まず、時間空間構造のフラクタル次元の局所指数について以下に説明する。ここで、振動信号データの三次元パワースペクトルアレイについて、その形状のフラクタル次元(ボックスカウント次元)の局所指数を次の手順で求めた。
Xi+1(t)=Xi(t+fN×TE) (1)
Pi(f)=10×log10Qi(f) (2)
[数10]
N(r)∝rD (3)
すなわち、
[数11]
N(r)=C×r-D(ただし、Cは定数である。) (4)
が成立する。ここで両辺の対数をとると、次式を得る。
logN(r)=-D×log(r)+log(C) (5)
logM(k)≒D×log(qk)+log(C) (6)
logM(k+1)≒D×log(qk+1)+log(C) (7)
L(k)
=(logM(k+1)-logM(k))/(log(qk+1)-log(qk))
=(logM(k+1)-logM(k))/log(q) (8)
(2)Xi(t)の両側及び片側パワースペクトルをSi(f)とQi(f)とすると、Xi(t)の確率密度関数がガウス(Gauss)分布の場合、情報エントロピー密度hiは次式で表わされる(例えば、非特許文献7参照。)。
