What is the Sound Beam?
The hyper sonic Sound Beam Technology is simply the most revolutionary
sound reproduction system of this century which allows you to remotely
and magically place sound "wherever you want it" up to 300'
away by simply "sending" the sound waves through space!
The sound only becomes apparent to the listener
when the traveling sound waves have made impact with a surface, be
it material, organic, or human. For example, if the Sound Beam is
used in a large exhibit space, and aimed in one particular direction
(let's say: a product, display, painting, etc., the visitors standing
in that immediate area will notice the sound emanating from the surfaces
within that targeted area, while others located elsewhere in the space
will not be impacted by the otherwise fully radiating sound of a traditional
loudspeaker. More to the point, and unlike a parabolic sound focusing
device, the Sound Beam is a flat transducer system which can easily
and unobtrusively be mounted on ceilings, walls, or floors, aimed
to secretly impact the surfaces where the sound is desirable.
Not
since the development of the "cone" loudspeaker more
than 75 years ago has any technology provided such
significant departure from conventional loudspeakers and such a remarkable
new approach to the reproduction of sound. The amazing property of
the Sound Beam technology is that, if aimed directly at a person's
head from several feet away, that person will mysteriously hear voices
or musical segments enveloping their head, as if wearing a pair of
headsets, and with no apparent sound source in sight! It is therefore
possible to specifically target the Sound Beam waves at a wall, floor,
furniture, object, or a person, depending on the effect desired.
How does it work? (the technical stuff!)
The basic operating principal of the Sound Beam uses a property of
air known as "non-linearity". A normal sound wave (like
someone talking) is a small pressure wave that travels through the
air. As the pressure goes up and down, the "non-linear" nature
of the air itself causes the sound wave to be changed slightly.
If you change a sound wave, new sounds (frequencies) are formed within
the wave. Therefore, if we know how the air affects the sound waves,
we can predict exactly what new frequencies (sounds) will be added
into the sound wave by the air itself. An ultrasonic (beyond the
range
of human hearing) sound wave can be sent into the air with sufficient
volume to cause the air to create these new frequencies. Since we
cannot hear the ultrasonic sound, we only hear the new sounds that
are formed by the non-linear action of the air.
Some ideas for applications
Automobiles -In-dash Sound Beam for private hands-free Cell Phone
conversations. Audio/Video Conferencing - Project the audio from
a
conference in different languages, from a single central device,
without
headphones. Paging Systems - Direct announcements to specific areas.
Retail Sales - Aim targeted advertising directly at the point of
purchase.
Drive Through Ordering - Direct communications with a motorist without
disrupting others nearby. Safety Officials - Portable "bull horn" type
device for communicating with a specific person or group. Military
Applications - Ship-to-ship communications, ship-board announcements.
Toys - Hand-held toy for kids to secretly communicate across the
street
from each other.
Public
Announcements - Highly focused announcements
in noisy environments such as subways, airports, amusement parks,
train stations, traffic intersections. Museums - Step on a floor
spot
labeled for a specific type of information or language, then magically
hear the needed information without noticing the apparent source.
A painting, sculpture or artifact describing themselves. Sports -
Focus sound into a crowd of people on a football field and talk only
to a selected few. Emergency Rescues - Rescuers communicate with
endangered
people far from reach.
