I went through in October, pretty quiet, temperature was OK, free desert camping or near free in the area where there is water an sewer. I also went near Yuma, BLM near the Colorado, I prefer that place since it is near the water, does not feel has dry as Quartz and Yuma is pretty close.
I would imagine there is a lot of Generator noise when the desert fills up, there must be a humming noise floating around all day long, people making coffee at 7 in the morning or watching TV late at night, or running all day long for AC or just running their anoying contractor genset.
I think it could be an experience to live this, but do not think I could stand this crowd for very long, I would prefer going in the desert, far from the noise.
