Cause of 1/f Noise: The Surge of Background Energy
  Based on analyzing various physical examples for 1/f noise we found that the 1/f noise is caused by generating conditions as resonance in acoustics and the effect of matter carrier is secondary. All the physical reasons are summarized into The surge of background energy, then the 1/f noise is separated from matter carrier. Therefore the attention is focus on the general characters of 1/f noise and the following viewpoints and results are of universal significance. The work about cause for 1/f Noise came to a universal relationship.   All the question about 1/f noise were solved completely and systematical. Follow-up study indicates that the crux of 1/f noise is a special phase whose entropy is very small.
