"something that's guaranteed to NEVER happen in any urban area"
Well, I don't know? Here at NN5 5PF I am getting 25-29 dBC on my (admittedly cheap) Maplin SPL meter and 25dB is I suspect ITS noise floor. That is if I stop breathing! The merest movement pops things up to 35-40dbC
I do not of course know how well calibrated it is but things like speech seem about right 70dB at a foot. NN5 is definitely not in the middle of nowhere! Yes, out in the suburbs but densely populated.
But 'countryside' is far from quiet! Yes, at 2am in the dark sub 30dB but once the pigeons are awake!! Even at 2am Hedgehogs make a terrific racket! I shall post some examples.

I have in the past posted several clips of me waffling and most have a noise floor around -70dB fs.
