There have been cases which seem to be legitimate of people demodulating RF in their bodies. It is commonly reported that incoming meteorites are sometimes "heard" by some people. (Is that indefinite enough :-) ). If this is not a psychological generation of apparent audio by visual stimulus then it *must* be caused by perception of RF signals as the sound path from the events in the very high atmosphere, if there was one, would take vastly longer than the viewing time.
