Been noticing this for a while now and finally decided to post about it. Recording sessions in the house I've been investigating near Solihull, and there's this distinct burst of white noise - almost like a radio losing signal - that shows up on the audio roughly 20 to 30 seconds before anything significant happens. Temperature drops, movement in peripheral vision, that sort of thing.
What I find interesting is that its not random interference. I've checked the equipment, ruled out local radio frequencies, even moved to a different recorder and the pattern held. Three separate sessions now with the same result.
My working theory is that whatever causes these phenomena also disrupts electromagnetic fields in the local environment beforehand, and the recorder is picking that up before our senses can. Kind of like a precursor signal.
Has anyone else documented this consistently enough to compare timestamps? I'm wondering if theres a measurable window between the static burst and the event itself that holds across different locations.
