I came across this while researching biological effects of microwave radiation.
Incapacitating Effect: Microwave Hearing
Microwave hearing is a phenomenon, described by human observers, as the sensations of buzzing, ticking, hissing, or knocking sounds that originate within or immediately behind the head. There is no sound propagating through the air like nomal sound. This technology in its crudest form could be used to distract individuals, if refined, it could also be used to communicate with hostages or hostage takers directly by Morse code or other message systems, possibly even by voice communcation.
Tunability
The phenomenon is tunable in that the characteristic sounds and intensities of those sounds depend on the characteristics of the RF energy as delivered. Because the frequency of the sound heard is dependent on the pulse characteristics of the RF energy, it seems possible that this technology could be developed to the point where words could be transmitted to be heard like the spoken word, except that it could only be heard within a person's head. In one experiment, communication of the words from one to ten using "speech modulated" microwave energy was successfully demonstrated. Microphones next to the person experiencing the voice could not pick up the sound. Additional development of this would open up a wide range of possibilities.

The use of the term "non-lethal" does not necessarily mean non-damaging and too often this has proven to be more vicious that what it would (superficially) imply.
Just a gut feeling.....but I have a very bad feeling about many "non-lethal" weapons.

If the situation allows, and the source is sufficiently powerful, there is the possibility to use this technology in a lethal mode as well.
I understand that applies to the microwave heater, but they would need to design these devices to work in a very narrow range of frequencies (e.g. the non heating ones) so you don't accidentally fry someone. Regardless, the possibilities this opens up are pretty awesome if you think about it! I wonder if they've done further research into this since 2006...?
