I've got two questions:
1) how do you record sound from space? I know we recorded the "sound" of the sun, but that was basically vibrations of the photosphere interpreted as what it would sound like if it were something solid vibrating in the atmosphere.
My point is - the sound you get from space objects is not dependent on the property or activity of that said object but on your instrumentation and interpretation. Therefore it's by definition rubbish and doesn't tell us anything.
2) Why would I trust UFOlogist with anything? UFOlogist is an oxymoron. Like when kids are pretending they're scientists.
