as the tiny flicker of light ignites above my head (cognitive impairment and all that stuff, you know).....Maybe I should pick up the book on antennas I have sitting beside me, but I only read the part on radio reception, where you wanted the antennas at a fraction of the received bandwidth.
Certainly since the Schumann generator is roughly half the footprint of a piece of paper and uses a wall wart power supply it can not generate much of a magnetic field (I gotta dig up mu gaussmeter).
The magnetic field should be toroidal since the loop antenna in the unit is in the form of a square pattern on a printed circuit board. I would assume that the field is then most intense when in line with the sides of the unit rather than in the vertical plane, directly above or below the unit. If so then placing the unit at the ear level would be preferable to placing on top of the head and thus the manuals admonition the place the unit at ear level. Sorry, just musing out loud....
Thanks,
Stu
