Directly measured, standardized, or well-supported in mainstream scientific or technical literature.
The underlying cycle is measurable, but the audible tone is an octave-transposed mapping used for comparison, listening, and practice rather than a naturally audible emission.
Review the evidence modelThe approximately 11-year solar cycle governs sunspot activity, solar flares, and geomagnetic storms. The full magnetic cycle is ~22 years (Hale cycle).
