OK, sounds good this time. I can't speak for what Petra hears, but I'd be pretty sure that what I hear would not be recorded by a microphone...unless it is sound outside of the range of human hearing that is transformed in the brain somehow. I suggested the other day that if Petra continues to establish credibility via a prediction record, that someone might want to see if a Physicist interested in earthquakes would want to look into this..of course, Petra is welcome to try and get a research physicist (by that I mean a professional physicist, not an amateur scientist with physics for a hobby) interested sooner.
