Plus, he said it was 'difficult' to reproduce over the television.
It is IMPOSSIBLE. There is a lower limit to what is broadcast, and most speakers...let alone those dinky shits inside televisions...don't even approach being able to reproduce anything in the lowest two octaves that we can hear.
Heck, even most subwoofers cheaper than a grand cannot reach the lowest octave...and even then most residential rooms wouldn't support the waveform without significant pressure lobing and cancellations.
So yeah, it is difficult.
If you go back to page 2 and look at the measurement I captured on an acoustic analyzer...you'll see increasing slopes of measured energy at BOTH extremes of our hearing limits. The device graph goes from 20-20kHz, and each level is one decibel...with the zero line 42dB, according to the numeric value...although the image is fuzzy, I can read it.
Some might wonder why I immediately introduce an acoustic measurement when I speculated the trouble is more likely EM. I was quite surprised to get this measurement, especially the indication that the out-of-range energy was increasing at an alarming rate...there is little likelihood that it just stops where WE stop hearing.
But then, we bump into the ElectroMagnetic spectrum of mere human perception...proven by the paper linked above, along with many other sources if one bothers to look.
You see...when EM energy is propogated within the range of acoustic perception...it can be heard. Outside of it, it is felt at the lower octaves...and I'm not quite sure what happens at above 20kHz.
So yeah...lots to consider here. I keep toying with the idea that The Hum is chordal in nature, and a manufactured phenomenon created by coupling with the natural heartbeat of the planet. That might help explain the surging and other phasey weirdness I hear and feel.
I still need to learn if the Schumann Resonance is any different than the 7.83 Hz average it's kept since its discovery. Sources are scant with any confirmation either way on-line.
The seismic monitors might not be the best sensors...larger coils may be necessary, using equipment without infrasonic filters. Standard microphones and recording equipment is heavily filtered to eliminate information beyond our normal range of hearing.
The stuff I have is reference gear, but I don't know what type of filtering is employed to limit the range of measurement.
I guess I could test it by creating an ELF EM radiator, and connect it to a frequency generator...but then I might bump into that odd law that Governor What'sHerName signed regarding creation of EMP weapons!
Cheers!
