To convert radio signals to audio you need a detector. Classically a simple diode can act in such a fashion as you may recall from elementary school projects where kids build such simple radios. People dont normally walk around with diodes or semiconductors in their eyeglass, teeth, etc. which could act in this fashion. An "antennae" alone is not sufficient to detect RF!
I suspect these reports are bogus, because if this kind of RF detection occured, everyone would be hearing buzzing when they pass by cell phone towers, TV transmitters, inside airplanes, using cell phones, etc, etc. which are much more potent and common sources of high RF flux than a grain of sand at 60km away!
I think this list has been saturated with too much of this nonsense already, IMHO.
