That's monster funny. The helmets don't seem to dampen anything and actually amplify certain frequency bands.. What a setback to all the tinoil idiots!
Btw.. I've always wondered about those foil hats.. Do the people wearing them think RF is only capable of approaching the brain from the above?
Shouldn't they be swaddling their entire head (and preferably neck and probably much of upper body too) with the stuff in order to achieve maximum "protection"?
Peace.
