[AMRadio] More on "Electromagnetic Allergies"

It is indeed possible that some people have the ability to detect some 
electromagnetic fields directly.   I recall a report I read in the 
1970s that there are at least some who seem to have an ability to 
demodulate AM signals and hear the audio - there was a patented design 
last century that coupled amplitude modulated RF to a person's body and 
the modulating audio could be "heard".  It was considered as a possible 
hearing aid or no-headphones monitoring method.  But results were not 
consistent and the field had to be strong and tightly-coupled to the 
body.    I'm forgetting what it was called... the "Neurophone" maybe?   
I don't think it is related to the ultrasonic thing being sold today 
under that name:  http://www.neurophone.com/

As I recall, I don't think anyone who tried it reported anything 
unpleasant or irritating.  Some didn't get it, some only heard 
something after extended exposure, some heard the audio right away.

But it seems highly unlikely that the weak fields produced by Wi-Fi, 
neighborhood cellphone sites, etc would produce a serious bodily 
reaction.  We are constantly awash in electromagnetic fields from the 
Sun, Earth, and the rest of the universe, as well as much stronger 
local man-made noise and radio and TV signals - wouldn't someone 
supposedly sensitive to weak fields like Wi-Fi and a neighborhood cell 
site have been bothered by the much stronger sources much earlier and 
to a greater degree?
