Back to the 3 x 30 KHz with music zapping in the 2 20-minute gaps. My sensitivity to the low-frequency signals returned to what it was before. Maybe there is a saturation point one reaches after an hour or so. Needs testing. As for an actual explanation, well, good luck with that!
In vibrational terms, maybe it is similar to the "dead" response for about 15 minutes after a resonance "hit" with Hulda Clark's syncrometer; or the null response for about 15 minutes after a sympathetic "hit" from friendly bacteria in Cleve Backster's experiments. Or maybe not.
