"Deadly noise weapons that can kill or maim may soon be part of
America's firepower."
LDAP Acoustic Beam Weapon
So read the first sentence of an article in the Daily Mirror, one of
England's largest newspapers on December 8, 1997. The article is
entitled: "Horrific noise gun set to go into battle." It further
states: " About 20 US Government laboratories and military bases are
working on acoustic weapons which can rupture organs, inflict burns
and cause death. They are now so highly developed that they could be
deployed at any moment, according to American expert William Arkin. A
blast from a rifle, helicopter or mine would release an energy beam
varying from a 90 to 120 decibel low-frequency to "shockwave" levels
at more than 170 decibels. Very low frequencies could cause internal
bleeding while the highest would destroy human flesh. Writing in the
quarterly journal Medicine, Conflict and Survival, consultant Mr Arkin
calls for international curbs on the new weapons on humanitarian
grounds."
Please take note of how this class of weapon "that could be deployed
at any moment (as of 1997)" operates. It targets victims with a "very
low frequency beam" that, with enough intensity, can "rupture organs,
inflict burns and cause death." Very low sound frequencies cannot be
heard by the human ear. They can only be felt. Therefore, these are
silent weapons that emit an invisible beam.
Who is the "American expert" credited as the source of this article?
Is he qualified to comment on the development of acoustic weapons?
William M. Arkin (
war...@igc.org) is a writer and consultant
specializing in national security affairs. He writes a bi-weekly
column Dot Mil for
washingtonpost.com on national security and the
Internet, and is a long time columnist for The Bulletin of the Atomic
Scientists. Arkin is a Senior Fellow at the Center for Strategic
Education at the Paul H. Nitze School of Advanced International
Studies (SAIS) at Johns Hopkins University. He serves as a consultant
to a number of non-profit and academic organizations on military and
Internet matters, and is a news contributor and consultant to MSNBC,
MSNBC.com, NBC News, Defense Daily, and Stars and Stripes Omnimedia
(

for news media organizations, the U.S. military, and private
organizations and foundations.
From the Military to Law Enforcement
Have acoustic weapons, like through-the-wall surveillance technology,
migrated from military applications to civilian law enforcement? The
following piece of evidence may help answer that question. On Nov. 18,
1998, the Synetics Corp. was awarded Department of Defense contract
#DAAE30-99-C-1003 for developing the "Difference Acoustic Wave
Generation System". This weapon generates a tightly focused ultrasound
beam that "may be remotely directed towards the target. With
sufficient energy, the resulting infrasonic waves (very low frequency
sound) can be disabling or lethal." Who is the intended customer for
these weapon systems? According to the contract, these are "...for
police and personal use". These units are also designed to be "man-
portable".*See footnote for links to contract information.
Please note that these weapons were designed to target a single
individual remotely with a focused acoustic beam. The designer's
intent is to make them light and portable enough to be carried by one
man. And, law enforcement (police) are among the intended customers of
this weapon. Synetics Corp., the above mentioned weapon developer no
longer has an active website. However, an archived version of the
website is still available online (if unavailable, an image of the
page can be seen here). It gives further insight into how this weapon
is controlled by the user. It states: " The remote station (for weapon
control) is hosted entirely on a Panasonic "Tough Book" (laptop
computer) and includes all of the system control software, a real time
live video display, and a joystick to direct the acoustic beams." In
essence, targeting a person remotely with a harmful acoustic beam is
as easy as playing a computer video game.
LRAD Long Range Acoustical DeviceThe evidence provided above discusses
the development of a prototype acoustic weapon. Is there evidence that
acoustic weapons are being manufactured and purchased by law
enforcement agencies? Yes. During the Republican National Convention
held in New York in 2004, numerous respected news agencies reported on
the presence of a weapon system named LRAD (Long Range Acoustical
Device). This unit, purchased by the New York Police Dept., was part
of their crowd control arsenal during that event. ABC News, in their
article "RNC To Feature Unusual Forms of Sound" made the following
statement regarding the capabilities of LRAD: "When in weapon mode,
LRAD blasts a tightly controlled stream of caustic sound that can be
turned up to high enough levels to trigger nausea or possibly
fainting. The operators themselves remain unaffected since the noise
is contained in its focused beam." In commenting on how the weapon is
operated, it further stated, "The sound beam is even equipped with a
viewfinder so the operator can precisely target the audio by finding a
person in cross hairs." The weapon is tunable so that it can deliver
audio messages or painful acoustic beams. And, that acoustic beam will
only be heard or felt by the person it targets.
A similar acoustic device named the LDAP (Low Dispersion Acoustic
Projector - see photo at top of this article) claims to have a longer
range for its focused acoustic beam than the above mentioned LRAD. The
manufacturer, called Wattre Corp., says its "HyperSpike" technology
"is able to deliver high Sound Pressure Levels (SPL) and pinpoint
beamwidth over distances never before possible." The resulting sound
is so intense that it wards off anyone approaching it. "Your cranium
hears it," the president told one newspaper. "The blast won't sound
like a baby crying or a scraped chalkboard," the paper added. "But it
will make a person feel the hyper-discomfort that comes with those
noises."
Scientific Applications and Research Associates, Inc. (SARA) is a
leading defense contractor for acoustic devices with less-than-lethal
weapons applications. According to The Independent, a leading
newspaper in the United Kingdom, SARA has developed a a gun that can
"fire shock waves that hit people "with enough force to knock them off
balance. [It] feels like having a bucket of cold water thrown on to
your chest" - according to a quoted SARA spokesperson.
Clearly, we see evidence of the development of acoustic weapons for
civilian and law enforcement applications. The next question we can
logically ask is: Can deadly sound weapons be used in concert with
through-the-wall surveillance to target people sleeping in their
homes? If so, how are they being used?

Defense contract referenced awarded to Synetics Corp, go to the Dept.
of Defense Small Business Innovation Research website. Using their
online search tool, search for the following phrases: "Parametric
Difference Waves for Low Frequency Acoustic Propagation," and
"Difference Acoustic Wave Generation System." The search results will
show the two contracts awarded for prototype acoustic weapons designed
by Synetics Corp.
Dept of Defense Solicitation Abstract Referencing Synetics Corp.
"Parametric Difference Waves for Low Frequency Acoustic Propagation"
Prior research indicates that an array of ultrasonic sources operated
with an offset in frequency will produce infrasonic or very low
frequency energy. This energy is useful because it is omni-
directional, and it propagates well with little absorption. With
sufficient energy, the resulting infrasonic waves can be disabling or
lethal. Synetics proposes an approach toward developing infrasonic
waves that can ultimately be incorporated into future man-portable
small arms weapon systems. This approach utilizes modernized pneumatic
technology which produces an extremely high-powered ultrasonic source.
The resulting frequency generated is precisely controlled such that
the desired high power infrasound frequency can be generated at the
target by beating two focused ultrasonic sources. BENEFITS: The
potential post applications of the parametric difference wave
generator include non-lethal crowd control, non-lethal self defense
units for police and personal use, and soot and crustacean removal
devices for commercial industries.
