Paul While it is true that few people have heard electrophoic sounds, the mechanism is well documented. It is rather easy to record the extremely low frequency ELF radiation from the plasma trail of the reentering Space Shuttle. You can even do it with a long wire antenna plugged right into the mic input of a small cassette recorder with no amplifier. Plans and results have been published in the past in Sky and Telescope magazine, Scientific American and other journals. The frequency is 50-100hz or lower and quite strong which would be consistent with generating audible vibrations.
