Human beings are so small, relative to a radio wavelength of 38,000 kilometers, that there's no way our anatomy could detect or interact with such a radio signal in any way.

It's increasingly hard to find a web page dedicated to the sales of alternative medicine products or New Age spirituality that does not cite the Schumann resonances as proof that some product or service is rooted in science. This mysterious number of 7.83 comes up again and again in sales pitches, as a sort of miracle frequency that can bring you health and wellness.

Try and calculate radiated power at 7.83Hz and see if your calculator has enough zeros.

A study by Reilly in 1999 showed that the threshold for direct perception of exposure to ELF RF by human volunteer subjects started at around 2 to 5 kV/m at 60 Hz with 10% of volunteers detecting the ELF expose at this level.[citation needed] The percent of detection raised to 50% of volunteers when the ELF level was rasised to 7 to 20 kV/m. 5% of all test subjects considered the perception of ELF at these thresholds as annoying.[citation needed]
