Schumann Resonances（舒曼共振音乐疗法）
According to information in Wikipedia, "The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere. This global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances occur because the space between the surface of the Earth and the conductive ionosphere acts as a closed waveguide. The limited dimensions of the Earth cause this waveguide to act as a resonant cavity for electromagnetic waves in the ELF band. The cavity is naturally excited by electric currents in lightning. Schumann resonances are the principal background in the electromagnetic spectrum beginning at 3 Hz and extend to 60 Hz, and appear as distinct peaks at extremely low frequencies (ELF) around 7.83 (fundamental), 14.3, 20.8, 27.3 and 33.8 Hz".
翻译：根据维基百科的信息，"舒曼共振（SR）是地球电磁场频谱极低频（ELF）部分的一组频谱峰值。舒曼共振是全球电磁共振，由地球表面和电离层形成的空腔中的雷电发射激发。这种全球电磁共振现象是以物理学家温弗里德·奥托·舒曼的名字命名的，他在1952年用数学方法预言了这一现象。舒曼产生共鸣是因为地球表面和导电电离层之间的空间充当了封闭的波导。地球的有限维度使这个波导在ELF波段中充当电磁波的共振腔。空腔自然被闪电中的电流激发。舒曼共振是电磁频谱的主要背景，从3赫兹开始，一直延伸到60赫兹，在7.83（基本）、14.3、20.8、27.3和33.8 Hz左右出现明显的峰值。
舒曼 1952 年描述的这些极低频率对我们重要吗？

Sound Frequency for Sleep
Brainwave entrainment through the use of binaural beats is a scientific method that helps you go from alert to relaxed to asleep within minutes by using a process to alter your brainwaves. Sounds like something straight out of a science fiction novel, but brainwave entrainment is a very real and very effective way to help you sleep. Your alertness is linked to the dominant frequency of your brainwaves. So if you’re feeling alert and focused, your brainwaves are in the beta frequency but if you’re feeling relaxed, they’re likely to be in the alpha state. To sleep, your brainwave frequency needs drop to a slow delta. This can be hard, especially after a busy day. Your brain stays alert, preventing you from relaxing. By using Binaural Beats, you can quickly induce the frequencies associated with sleep in your brain within minutes. Scientists discovered that the brain synchronises itself to a dominant frequency. So by inducing a new lower frequency with binaural beats, your brain begins to lower its own frequency to match this new frequency. It’s a powerful technology that I’ve been using myself for years with very good results.
睡眠声音频率
通过使用双耳节拍进行脑电波训练是一种科学方法，它通过改变脑电波的过程，帮助你在几分钟内从警觉到放松到睡眠。听起来像是科幻小说中直接写的东西， 但脑电波约束是帮助你入睡的一种非常真实和非常有效的方法。你的警觉性与脑电波的主要频率有关。所以，如果你感到警觉和专注，你的脑电波是在测试版频率，但如果你感到放松，他们很可能在阿尔法状态。要入睡，你的脑电波频率需要下降到一个缓慢的增量。这很难，尤其是在忙碌了一天之后。你的大脑保持警觉，阻止你放松。通过使用双耳节拍，您可以在几分钟内快速诱导大脑中与睡眠相关的频率。科学家发现大脑与占统治地位的频率同步。因此，通过诱导一个新的低频与双耳节拍，你的大脑开始降低自己的频率，以配合这个新的频率。这是一个强大的技术，我一直在使用自己多年，并取得了非常好的结果。
