Are there mathematical models which suggest which of the two - desert or recording studio - is likely to be quieter? I would think a recording studio would be quieter than a desert. Is there a mathematical model which suggests this?

No. Background noise levels in recording studios and outside vary a lot from situation to situation. Outside is typically quite loud but if there is no wind, no air movement, no animal noises, and no traffic/planes/machinery/power lines levels can drop quite low.
Studios are equally variable. Some are designed to be very quiet inside, others are not.
