CORPORATION DEVISES NEW CROWD TORTURE WEAPON

New Scientist A US company claims it is ready to build a microwave ray gun able to beam sounds directly into people's heads. The device ­ dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) ­ exploits the microwave audio effect, in which short microwave pulses rapidly heat tissue, causing a shockwave inside the skull that can be detected by the ears. A series of pulses can be transmitted to produce recognizable sounds. The device is aimed for military or crowd-control applications, but may have other uses. . .

MEDUSA involves a microwave auditory effect "loud" enough to cause discomfort or even incapacitation. Sadovnik says that normal audio safety limits do not apply since the sound does not enter through the eardrums. . .

Sadovnik says the device will work thanks to a new reconfigurable antenna developed by colleague Vladimir Manasson. It steers the beam electronically, making it possible to flip from a broad to a narrow beam, or aim at multiple targets simultaneously.

Sadovnik says the technology could have non-military applications. Birds seem to be highly sensitive to microwave audio, he says, so it might be used to scare away unwanted flocks.
