For those who don't know, a wavelength of 1 decimeter (1/10th of a meter) is ~3 GHz. 5 decimeters, 600 MHz. 1 meter, 300 MHz.

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 normal 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 communication."
"One study (in 1975) using human volunteers, identified the threshold energy of microwave-auditory responses in humans as a function of pulse width for 2450 MHz radiofrequcncy energy. It is also found that about 40 J/cm2 incident energy density per pulse was required."
"Application of the microwave hearing technology could facilitate a private message transmission. It may be useful to provide a disruptive condition to a person not aware of the technology. Not only might it be disruptive to the sense of hearing, it could be psychologically devastating if one suddenly heard "voices within one's head."
"The effective range could be hundreds of meters."
