It sounds like a very low hum. In fact its worse in the middle of nowhere with nothing to mask it. Ever hear that spooky 'its an alien planet' background music on the old Star Trek? Its like that. I spent a lot of time up there in AK, and in the desert. The planetary magnetic field resonates, resonant currents create infrasound in semiconductors (like sand or moist air, or your inner ear), just like transducers.. A lot of appliance noise comes from tuned coil-capacitor circuits; alternating currents/fields cause the coil and capcitor materials to vibrate, coupling the EM field to the air in a way we can physically hear. Then of course there is good old tintinitus.
