與地球本身相繫的音頻：來自天空的 Schumann 共振，以及地球公轉一年所化成、可聽見的八度音。 兩種截然不同的量度在此交會。Schumann 共振是一種真實存在的電磁駐波，迴盪於地球表面與電離層之間的空腔，最早由物理學家 Winfried Otto Schumann 於 1952 年計算得出。地球年音則源自 Cousto 的八度：將一次公轉的週期不斷向上疊升，直到化為可聽見的聲音。兩者都是聆聽地球自身時間節律的方式。 Independent of any tradition, controlled clinical evidence that a specific frequency produces a specific health effect is limited and mixed. Auriviel presents these tunings as music and contemplative practice. This page is for general information and relaxation. Auriviel's frequency music is not medical advice, diagnosis, or treatment, and no health outcome is claimed. If you have a medical concern, please consult a qualified professional.
