Here are some interesting articles I came across about some of the
latest research in the field of sound and its effect on the
surrounding environment. It might provide a wonderful insight on the
scientific nature of Tantra, which was known to Rishis long ago, and
currently brought to the common man by great souls such as Shri
Paramhans Nikhileshwaranand Ji and others.

In 1967, Hans Jenny, a Swiss doctor, published the book Cymatics -
The Structure and Dynamics of Waves and Vibrations.

In this book Jenny showed what happens when one takes various
materials like sand, spores, iron filings, water, etc., and places
them on vibrating metal plates. What appears are shapes and motion -
patterns which vary from the nearly perfectly ordered and stationary
to those that are excitingly chaotic and constantly in motion. Jenny
created an invention of his own called a tonoscope which made use of
crystal oscillators to set these metal plates into motion. Unlike in
previous experiments. Jenny could precisely control the rate of
vibration and repeat experiments attaining identical results.

"The tonoscope was constructed to make the human voice visible
without any electronic apparatus as an intermediate link. This
yielded the amazing possibility of being able to see the physical
image of the vowel, tone or song a human being produced directly. Not
only could you hear a melody - you could see it."

In his research with the tonoscope, Jenny noticed that when the
vowels of the ancient languages of Hebrew and Sanskrit were
pronounced, the sand took the shape of the written symbols for these
vowels. Experimentation with modern languages general produced chaos.
Is it possible that the ancient Hebrews and Indians knew this? Could
there be something to the concept of "sacred language?" Would other
sacred languages produce similar results ie. Tibetan, Egyptian or
Chinese. These languages have always proposed that they have the
capacity to influence and transform physical reality through the
recitation or chanting of sacred syllables and mantras.

One of Jenny's most interesting results with the tonoscope was
produced when he took a vibrating plate covered with liquid and
tilted it. "The liquid did not yield to gravitational influence and
run off the vibrating plate but stayed on and went on constructing
new shapes as though nothing had happened." If, however, the
oscillation was then turned off, the liquid began to run. But if the
tonoscope was turned back on and the vibrations re-established,
quickly, before the liquid ran off the plate he not only could
prevent the liquid from leaving the plate but actually set it back
into its original position. According to Jenny, this was an example
of an anti gravitational effect created by vibrations.

Jenny, also, pointed out the resemblance between the shapes and
patterns we see around us in our physical reality and the shapes and
patterns he generated in his experiments. Jenny stipulated the theory
that biological evolution was a result of vibrations.

"There is a similarity between cymatic pictures and quantum
particles. In both cases that which appears to be a solid form is
also a wave. They are both created and simultaneously organized by
the principle of pulse (the principle of vibration). This is the
great mystery with sound: there is no solidity! A form that appears
solid is actually created by an underlying vibration." (Beaulieu)

In his book, Jenny says that the key to understanding how we can heal
the body lies in our understanding of how different frequencies
or "tones" influence our physical reality.

The Physics of Sound and Music

We don't often think of the physics of sound, and the fact that sound
has power to effect physical objects. Just the mere fact that you
perceive sound shows this vibrational nature. The sound waves cause
your eardrums to vibrate, which causes a chain reaction in your
middle and inner ear. This eventually causes nerve impulses to reach
your brain that are perceived as sound.

To truly appreciate the power that sound can have, it helps to think
of two examples. An earthquake is actually a series of sound waves
caused by two plates of earth sliding by each other in a quick
motion. The scraping that ensues causes a sound wave to be produced.
Sound travels faster in the air than it does in the denser earth, so
you can often hear an earthquake before you feel it. We all know
about the power and destructive capabilities of an earthquake.
Another example of the destructive power of sound is the ability of
some singers to break a glass merely by singing a particular note.
Both the example of the earthquake and that of the singer illustrate
the characteristic principle of resonance.

Our bodies also resonate or vibrate in response to and in concert
with sound waves that we are exposed to. In fact, there is some
fascinating research that's been done that even shows the
relationships of this resonance to the planets of our solar system.
Our DNA and RNA molecules, which are the building blocks of our very
chromosomes, resonate to an octave tone (a musical relationship) of
the earth's rotation pattern. Is it any wonder that with our DNA
vibrating in concert to the energies we are exposed to, that when we
listen to certain kinds of music we could be damaging our own bodies
and those of future generations (through our chromosomes).

The different frequencies of the sound waves that are produced when a
musical instrument is played correspond to various musical notes. For
example, a sound wave that produces the note that is commonly
called "concert A" vibrates at a frequency of 440 cycles per second
(hertz or Hz). Different parts of your body resonate with different
notes and the harmonics produced by different types of musical
instruments. Each one of us becomes a magnificent dance of tissues,
cells, molecules, atoms, and energy fields swirling in rhythm to the
beat of the sound waves. When this dance is a dance of harmony, it is
healing and life giving. When the dance is one of dissonance and
disharmony it brings on disease and it takes away life energy.

This dance of nature to sound and music was visually demonstrated by
two different scientists in similar ways. An eighteenth century
physicist named Ernest Chladni investigated the effects of sound an
music on matter by sprinkling sand on steel disks and watching what
happened when a violin played various notes. The changing patterns
that were produced were striking in their symmetry and artistic and
mathematically precise patterns.

In this century, Dr. Hans Jenny took Chladni's work a few steps
further. Dr. Jenny devised a device he called a "tonoscope," which
consisted of a metal plate on top of an oscillator. The oscillator
produces vibrations in the plate that are adjustable according to
volume and pitch. When different materials are placed on the
tonoscope, patterns emerge in response to the vibrations that are
very much like patterns found in nature. For example when paste is
placed on the tonoscope, a patterns emerges which looks like the
early stages of cell division. Other substances mimicked honeycombs
and nautilus shells. A pattern produced when a crescendo of sound
vibrated through powder looked remarkably like the iris and pupil of
an eye.

However, one of the most fascinating results occurred when Jenny used
a microphone to vibrate the tonoscope. When he uttered the ancient
mantra, AUM or "Ohm", a pattern was produced which consisted of a
perfect circle filled with concentric squares and triangles.
Coincidentally, the very same pattern is found in the yantra or
geometric artwork that has been used for centuries in the East to
represent the AUM, the so-called mantra of mantras. Once again,
science demonstrates the profound relationship that sound has with
matter.

Another profound relationship that sound has with our bodies and
minds was discovered by a French ear specialist named Dr. Alfred
Tomatis. Dr.Tomatis spent decades measuring the affects of different
sound frequencies on our bodies. He researched which frequencies
boost energy and which ones deplete it and how they bring about these
effects. He came to a startling conclusion. Dr. Tomatis says, "The
ear is made not only for hearing. The ear is designed to energize the
brain and body."

How can we possibly get energy through our ears? Well, in our
previous discussion of the power that music has, we talked about
resonance and how the right frequencies of sound waves produce
sympathetic vibrations in other physical objects, including our
bodies. Tomatis discovered that certain kinds of music, which had an
abundance of certain frequency ranges, actually were effective in
recharging the central gray nuclei cells in the brain. These cells
act like tiny batteries that power your brainwaves. You would expect
that these tiny batteries must be recharged by your body's internal
systems and metabolism. Tomatis found otherwise.

Dr. Tomatis discovered that it wasn't something inside you that
recharged these brain cells, it was certain frequencies of sound from
outside your body that provide the recharge. As sound travels through
your inner ear, it whirls around and around through the coils of the
snail shaped cochlea. From there it comes upon a long line of 24,600
cells called Corti cells, which dance a perfectly synchronized dance
to each sound. This dance of the Corti cells produces energy that
splits off, some going to the brain and some going to the vestibular
branch of your auditory nerve and then to the muscles throughout your
body.

So, with all we've discussed about the benefits of certain kinds of
music, what kinds of music would you expect to have the ability to
produce the most energizing of the brain as well as the most release
of muscle tension and improvement of bodily functions and posture.
The same Baroque and Classical music that we've discussed before,
especially those pieces rich in strings, produce frequencies that
Tomatis found to be energizing and healing. In fact, Tomatis found
that it is possible to rejuvenate your ears with sound.

Dr. Tomatis developed and patented a devise he calls the Electronic
Ear. This device emits bursts of different high and low frequency
sounds, alternating from ear to ear. This process effectively
exercises the muscles of the middle ear so that they get in shape and
work as they are supposed to. Tomatis found that sounds in the range
of 5,000 to 8,000 hertz recharge the cells that are like tiny
batteries in our brains the fastest. He also found that the music
that is the richest in these high frequency sounds is that of Mozart.
And, he went on to pinpoint those sounds that were damaging to the
body and the mind. These were low frequency sounds, like the noise at
an airport, a construction site, in traffic, etc. Tomatis also
singled out the low pounding sounds in rock music as "brain drain"
sounds.

Others have taken the same frequency ranges that Tomatis worked with
and found that these appear to universally benefit life. A researcher
named Dan Carlson found that 5,000 hertz also energizes plants. He
performed experiments in which he embedded a 5,000 hertz pulsed sound
(which resembled big cricket sounds) in tapes of Baroque and other
classical music. He played these tapes to plants as he sprayed them
with a nutrient mix. He found that the plants showed a 700 percent
increase in efficiency of absorbing the nutrients. It was discovered
that this frequency of sound actually helps the little pores on the
plant's leaves called stomata, to open up. Guess what the frequency
of bird song is. Yes, it's around 5,000 hertz. And who says nature
doesn't have a plan. You'll find that in areas that don't have a lot
of birds singing, there's not a lot of plant growth either.

Speaking of plant growth, Dan Carlson found that his mix of life
enhancing music and spraying of nutrients on his purple passion plant
produced some record results. He was able to take a plant that
normally grows to a height of around 18 inches and produced a plant
that grew 1,400 feet long in the course of two and a half years! This
feat earned Mr. Carlson and his plant a place in the Guinness Book of
World Records.

Researchers have also applied this 5,000 hertz frequency to studies
on people. A recent test was done using this frequency added to
Baroque music played while people ate dinner at a restaurant. It was
found that people who ate to slow classical music ate more slowly,
digested better, and didn't gain weight. On the other hand, those
that ate to rock music ate very quickly, digested poorly, and gained
weight.

In addition to benefiting the body and its functioning, Tomatis
discovered that these life giving frequencies could bring
psychological health also. He found that he was able to help learning
disabled and even autistic children to lead normal lives. One of his
lines of research revolved around the sounds that a baby hears when
in the womb. Tomatis discovered that by placing a specially sealed
microphone and speaker into water he could simulate the sonic
environment that a baby experiences before birth. When Tomatis played
the sounds of a mother's voice through this fluid media to her
autistic child, the child went over and turned off the lights,
climbed onto his mother's lap, assumed the fetal position and started
sucking his thumb. Over time, by gradually substituting the mother's
voice through regular speakers instead of through the fluid media,
Tomatis was able to get the child babbling and eventually brought the
child to complete normalcy.

Guess which sound frequencies predominate in the fluid environment
that Tomatis used. They are some of the same sound frequencies that
dolphins make and the same frequencies found quite often in bird
song. It was also the same frequencies that Tomatis found to be most
beneficial for recharging your brain cells - around 8,000 Hertz!

Choose what you and your children listen to, and choose carefully!

Using sound waves and resonance, we can change the form of matter.
When a sound frequency matches the vibrational frequency of any
structure, resonance occurs. You can hear examples of this when you
sing a note and the same note sounds on a stringed instrument like a
guitar or piano. The changes sound produces can be quite dramatic, as
in the classic example of a singer shattering a glass with the voice.
Sound is now being used in the medical field to treat certain
conditions. A treatment called extracorporeal shock wave lithotripsy
uses sound waves to disintegrate gallstones. In 1940, the Tacoma
Narrows Bridge in Washington state collapsed due to relatively mild
gusts of wind. The wind started the main span of the bridge vibrating
at it's natural frequency, causing it to sway and ripple violently,
then collapse.

Aside from these destructive examples, sound can also CREATE form.
Sound can create complex geometric patterns in various substances.
Hans Jenny found in his research of cymatics that the sounds of
vowels in ancient Hebrew and Sanskrit actually produce patterns that
resemble the alphabetic symbols used for the sounds. Jenny invented
an istrument called a tonoscope, which allows you see the pattern a
sound creates. When the mantra AUM is chanted into a tonoscope, it
produces a pattern that looks like the Sri Yantra mandala, the most
holy symbol of Hindu tradition. It symbolizes the divine creative
aspect of sacred sound, out of which the manifestation of the
physical universe is generated, and the merging of one's soul back
into the Absolute Consciousness.

Many spiritual teachings speak of the role of sound in manifesting
form. In the creation story of the Christian Bible, notice that it
says God invoked Light with sound. According to Buddhist
teaching...it is said that if AUM is chanted in just the right way,
this world will cease to exist in it's present form.
