New Security Technology: projecting a silent microwave scream inside your head
July 9 2008 | 0 comment(s)
The US military has bankrolled early development of a non-lethal
microwave weapon that can cause sound inside the target's head.
The Mob Excess Deterrent Using Silent Audio
("MEDUSA") is based on a well-known phenomenon, but the link to
potential military use has only recently been made. When active, the
MEDUSA's microwave beam causes shockwaves inside its targets' skulls
which can be detected by the ears. A series of microwave pulses can
also be created to produce recognisable sounds.
The MEDUSA's
advantage lies in that the generated sound originates from within the
skull, and cannot be blocked out by conventional means such as
earplugs. Depending on the intensity of the beam, the effect can range
from annoyance to incapacitation. Conversely, personnel situated
outside the MEDUSA's beam will be completely unaffected.
In
addition to potential applications on the battlefield and in crowd
control, the technology behind the MEDUSA may also be of assistance to
people with outer ear problems that impair their normal hearing.
