It’s interesting how similar the whistler waves sound (in a quick and low-volume listening, by me) to the sound of wrench-taps on large-antenna guywires. If I recall, the latter were the sound sample used for ray-guns in the early Star Wars movies. (I have no idea what was done later; maybe they kept and re-used the same samples.)
Is there a good reason the time-frequency distribution should be (auditorily, at low volume, to me) similar in the ionosphere-waveguide and tensed-steel media? I guess if I weren’t lazy, this is a topic in my domains, and I could go try to answer that question myself.
