δ波(DELTA / δ wave)

0-4Hz生物电波

θ波(THETA / θ wave)

4-7Hz生物电波

α波(ALPHA / α wave)

8-13Hz生物电波
β波(BETA / β wave)13-40Hz生物电波

α脑电波音乐的网上的两种定义:

定义备注
音乐的声波带有alpha波段(8-13Hz)的声波(错误定义)

属于错误定义

这类声波需要专门的音响外放或者耳机设备才能听到,

而且该声音属于次声波范围,对人体有害。

音乐的声波处于20Hz~20000Hz,但是能激发大脑产生alpha电波。(这种是我们想要的)属于正确定义

根据[3]可知

"α脑波音乐"在某些场景下是被曲解和混淆概念。

因为α脑波音乐是电波,而音乐是声波。

电波≠声波,两者无法进行100%互相等频率转化。

还有一种音乐,最早来自论文[4]

认为听莫扎特的K488会有利于提升智商,

这篇论文确实提示,此类音乐会提升智商,但是并未提及与α脑波相关。

根据[11],提升智力的脑波是SMR beta 波和gamma波(注:该信息来自销售网站,不权威)

[6]中显示音乐确实可以影响脑波,具体哪些音乐没说。

什么是真正的alpha音乐?

根据斯坦福的学术新闻[8]

Music with a strong beat stimulates the brain and ultimately causes brainwaves to resonate in time with the rhythm, research has shown. Slow beats encourage the slow brainwaves that are associated with hypnotic or meditative states. Faster beats may encourage more alert and concentrated thinking.(满节拍的 音乐也促进更慢的脑电波)

显然,我们应该听慢节拍或者说少节拍的音乐,才能更有利于alpha脑波的产生。

Most music combines many different frequencies that cause a complex set of reactions in the brain, but researchers say specific pieces of music could enhance concentration or promote relaxation. "If we can get some reliable evidence from neuroscientists that music therapy works, music is cheap and nearly anybody can get access to it," Russell said.(会议中提到,研究人员也知道音乐其实都包含了各种频率)

"For most of us, the brain is locked into a particular level of functioning," the psychologist said. "If we ultimately speed up or slow down the brainwave activity, then it becomes much easier for the brain to shift its speed as needed."(大脑活动性是具有不同段位level的,不是连续的。)


Music with a strong beat stimulates the brain and ultimately causes brainwaves to resonate in time with the rhythm, research has shown. Slow beats encourage the slow brainwaves that are associated with hypnotic or meditative states. Faster beats may encourage more alert and concentrated thinking.(慢节拍 有助于慢脑波,有助于冥想)

这里注释一句,音乐声波频率是不是能慢到8-13Hz呢?不可能, 这是次声波范围,人耳是听不到的。[9]中提到的resonate指的是声波的节拍(beat)和脑电波共振,而不是声波的频率和脑电波共振。

声音的频率(frequency)和节拍(beat)区别?

frequency有两种意思:

①乐器的敲打和摩擦(例如小提琴)导致接触面的机械振动导致的频率

②指的是节拍,此时frequency意思同beat,根据[10]:

 Current findings indicate that music around 60 beats per minute can cause the brain to synchronize with the beat causing alpha brainwaves (frequencies from 8 - 14 hertz or cycles per second).

所以alpha脑电波的频率我们在不具备测量仪器的条件下,无法根据①来寻找(因为alpha脑电波范围是8-13Hz

我们只能根据②来寻找alpha脑波音乐,根据[10](注:该信息来自非知名国外大学,结论不一定权威)

的说法:
how do you choose the relaxation music that is best for you? The answer partly rests with you: You must first like the music being played, and then it must relax you. 

也就是说,让你放松的音乐首先必须是适合你的。

也就是说,alpha脑波音乐要满足两个条件:

①适合你的,让你放松的,例如[10]中的Buddha Spirit我就不喜欢,听了不太舒服。

60 beats per minute[10]

▶ The Winding Path (163.com)

打开这个网易云音乐,其中13秒-21秒,几乎就是完美的一秒一拍,就是我们想要的60拍一分钟,

当然整个曲子的其他部分肯定有不满足疫苗一拍的地方,但是整体听起来就很放松很舒服。

######################################################################

写在最后,其实没有完美的alpha脑波音乐,刚刚好听了之后就在你脑海中产生很精准的阿尔法波。都是属于“实验性质”的论文,而不是“数理逻辑严谨推导”的论文。

选择适合自己的alpha脑波音乐:

①适合某些人relax,但是另外人听着却不太舒服,

②音乐的旋律60 beats per minute(允许音乐中途更换乐器、更换音调的高低),具体的例子就是上面提到的

▶ The Winding Path (163.com)

当然也可以是其他音乐。
