Please note that the frequency hovers always between 7.25 and 8.25. If the base frequency changed it would likely kill all DNA species on earth. All they can do right now to help our brains ascend is turn up the amplitude of the sound. That is very likely the very low hum we hear in our inner ear. The frequency fluctuation helps our cells change too.
The sound is changing every cell of our bodies and all the plants, animals, and the earth. This is 3D, 4D Sync so spacetime.
The Reiki I do in my office also fluctuates but it is astral level, 5D into spacetime sync. People can feel it. That said, all the dimensions are one with our bodies
