I experienced this once at a "star party" with about 15 serious observers. Some people heard it, others didn't. I'd never heard of the effect at the time. As it was happening, there was the typical "ahhhs" from the group - then after it was over, some of us were struck by the sudden realization: hey, that's not possible! It wasn't a 100hz hum, it was more like a white noise hiss. I decided that it was just the power of suggestion, since I had no idea how it could be possible. Years later, I ran across the electrophonic info and realized that's what we had experienced. There was a 100 foot long wire right over our heads (my shortwave antenna) and a 20 foot tall metal lamp post nearby, I was probably wearing glasses (I don't recall if they were actually on my head at the time). I realize that's just another anecdote for most people, but having heard it, I'm convinced that its *something*.
