Sound as a Weapon
Author unknown

Keywords: Sound Weapon, Infrasonic Weapon, Ultrasonic Weapon, Sonic
Bullets, Non-lethal Weapon

Sound is mostly associated with something we hear. We listen to people
talking, music on the radio, and other type of sounds. But what most
people don't know is that sound can be used as a weapon.

Sound below the hearing range (20 Hz) of a human is called infrasonic,
and above human hearing rang (20 kHz) is ultrasonic. A laser is an
electromagnetic wave with a single wavelength that can be focused and
targeted on an object. CD players use a laser to read information off a
CD. Sound, however, is an atmospheric wave. Can a focused sound wave be
generated and used to strike an object. The answer is yes.

Sound waves with high amplitudes can be used as a weapon. This is not
the type of sound you hear but the type of sound you would feel in an
explosion. A shock wave. If you have two or more focused sound waves,
they can be angled and combined at some focal point. The combining of
the waves at the focal point can produce a very powerful wave. One of
the focused waves modulated with information can control the result of
the final wave.

The final wave can be infrasonic, audible, or ultrasonic. This
technology can be used to direct an audible message to a person by
aiming the device at the side of the target's head, near one ear. This
message can be sent to only one person in a room filled with people, or
while the person is just lying in bed. The message can be sent from the
same house or the house next door. The ultrasonic waves will travel
through walls of a house with little loss before combining to produce
the audible message.

The waves passing through the walls will not damage the house in
anyway. A person could be tricked into thinking that God is speaking to
them, for example. Depending on the targeted person's state of mind, he
or she could be manipulated into doing something that he or she would
not normally do.

This technology can be used as a very effective weapon. Powerful
ultrasonic focused sound waves can be fired through a house without
damaging the house in anyway. These waves could have amplitudes of
several inches. If a person is struck by these focused waves as they
pass through a house, the person could feel a slight tap or a strong
violent jolt, depending on the strength and distance of the weapon.
Strong infrasonic or ultrasonic sound waves passing through the head,
neck, or chest can cause gasping for breath, head pains, or a choking
effect.

The firing point of the weapon could be from inside of the house next
door or the inside of the house across the street. Since the weapon is
hidden inside of a house and no damage is done to either house, it is
virtually impossible to visually detect it. The wave after striking its
target and passing through the targeted house will dissipate in the
atmosphere over a distance. This is truly a vanishing bullet.

Ultrasonic waves can not only pass through a house wall without causing
any damage but can also pass through stone, brick, and metal. There is
no safe place from these weapons in a conventional house. Total
protection from these infrasonic and ultrasonic waves is limited to a
vacuum, no air. Sound cannot pass through a vacuum. Vacuum barriers
placed around a targeted person can render these sound weapons useless.


Weapons such as these are useless unless they are able to strike a
human target. A targeting system that can target a person through the
walls of a house is needed. Imaging technology now exist that can
display images of individuals inside a house or building. I believe the
imaging technology uses electromagnetic waves that reflect back on
surfaces close to body temperature. The reflective waves would be used
to build an image of people inside the house.

The combining of the above mentioned sound weapons and this targeting
system insure precise identification and targeting of the human target.
The targeting system and weapon can be made mobile. The equipment can
be hidden in the back of a small truck or van. The vehicle would be
parked near the building of the where the targeted person is. A person
hiding in the back of the vehicle can target and fire the weapon at the
targeted person in the building. As long as the general vicinity of the
person is known, the targeted person can be identified and targeted by
body detail using the targeting system.

The weapon produces a very powerful ultrasonic frequency and the wave
has tremendous distance. The wave can be fired through the head of the
targeted person. The frequency of the sound wave is quickly varied from
a frequency that will penetrate the skull easily to one which will not.
The targeted person will feel this wave passing through his or her
head. This will most certainly intimidate a person. Both the targeting
system and weapon are very expensive.

Harassment groups are currently using this technology to assist
neighborhood communities with the task of riding their communities of
unwelcome neighbors. This technology is extremely effective. It could
be used to keep the targeted person awake all night by striking the
person throughout the night, possibly causing the person to lose their
job because of poor work performance from lack of sleep. It is
impossible to sleep through a strong sound wave passing through your
body. The income earner of a family can be singled out and targeted in
a family situation.

It is possible to run a person or a family out of their house with this
technology. The local police will not know how to handle a situation
like this. They have no equipment to detect the targeting system or
weapon. These weapons leave no visual marks on the human body after
being struck, so no physical evidence can be produced for the police.
The police will just assume the targeted person is crazy and brush them
off. Detection devices are needed to detect this technology. More types
harassment groups will discover the potential of this technology and
quickly employ it. These weapons are designed for one purpose, to
terrorize people.

Oh yeah...us crazy mericans have a secret sound anti terror force
according to one AOL user.

Just think you could make your neighbor think your God.

Sortta like all the voices bouncing around in Commode Robs head.

It's all pure crap.

Attenuation


Most engineers and scientists working in the ultrasound characterize
attenuation as the "half-value layer," or the "half-power distance." These
terms refer to the distance that ultrasound will travel in a particular
tissue before its amplitude or energy is attenuated to half its original
value.





Attenuation


Divergence of the wavefront

Elastic reflection of wave energy

Elastic scattering of wave energy

Absorption of wave energy





Ultrasound Attenuation


Material Half-power distance (cm)

Water 380

Blood 15

Soft tissue 5 to 1

except muscle 1 to 0.6

Bone 0.7 to 0.2

Air 0.08

Lung 0.05





Attenuation in Tissue


Ultrasound energy can travel in water 380 cm before its power decreases to
half of its original value.

Attenuation is greater in soft tissue, and even greater in muscle.

Thus, a thick muscled chest wall will offer a significant obstacle to the
transmission of ultrasound.





Attenuation in Tissue


Non-muscle tissue such as fat does not attenuate acoustic energy as much.

The halfpower distance for bone is still less than muscle, which explains
why bone is such a barrier to ultrasound.

Air and lung tissue have extremely short half-power distances and represent
severe obstacles to the transmission of acoustic energy.





Attenuation


As a general rule, the attenuation coefficient is doubled when the frequency
is doubled.





Beam Forming


Ultrasound beam can be shaped with lenses

Ultrasound transducers (and other antennae) emit energy in three fields

Near field (Fresnel region)

Focused field

Far field (Fraunhofer region)





Diagnostic scanning modes


Usually pulse-echo mode

Further classification depends on how information is displayed






A mode


Amplitude of pressure wave displayed with regard to position


Thickness of cornea





B mode


Amplitudes are represented as pixels (images)

Brightness of pixels - signal strength (Brightness mode)

256 brightness levels/256 gray scales






Shift beam after each transmission to get 2D image





M mode


M (motion) mode

Beam held in fixed position

Measure very fast motions

Heart valves



*******************

Here's typically ultrasound numbers:

In .08cm the ultrasound in air is 1/2 power. It looses 1/2 power every
..031 inches or 25 dB per foot due to spreading. The claims Joe pointed out
nearly match RB's claims about his boat or stereo.

Glory!

Interesting Joe...... but I've already handled the problem via posting
the entire length of our boundary with his lot with signs stating this is a
"Radon Gas Zone"


Dropped his property value by 50%
