The fluctuation of 1/f is the same as the rhythm of a living organism.
The natural wind is truly a 1/f fluctuation.
The strength, direction, and manner of blowing are irregularly changing.
The natural breathing of the air is very comforting.
In PAC housing
I recommend a ceiling fan with 1/f fluctuation.
Solid wood, real plaster, and subtle changes in the composition of the open space.
It seems that the living space itself become a space of 1/f fluctuation.
The goodness of handmade
The goodness of nature
The goodness that is not uniform
These seem to create the fluctuation of 1/f.
