Keeping Radio Signals out of Your Head
A common paranoia seems to involve radio signals being beamed into your head. Sometimes the fear is aliens and sometimes it's the US government. Sometimes the fear is even that the signals are beamed FROM your head, perhaps by a secret implanted transmitter.
A team of four men from MIT's Electrical Engineering and Computer Science department and Media Laboratory, devised a series of experiments to determine if the commonly held notion (among the paranoid) that tin foil helmets could shield the head was valid. They used over US$250,000 of equipment and a well planned experimental protocol.
The study seems legit. They experimented with three types of helmets: the classical "Tin Foil conforming to head shape" style, the Fez, and the Centurion.
Results? Well, lets just say these helmet types don't work very well. Quoting the study, they "encourage the paranoid community to develop improved helmet designs to avoid falling prey to these shortcomings."
