Humans have long considered sound and music as mystical and magical, whether worshipped by the ancients and embedded in political and culture in ancient China, regarded as a portal to the infinite by Buddhists chanting OM, or modern day musicians and sound designers revelling in and revering their own sound creations. Sound inspires poets and sculptures across the world, leaders, rebels, teachers and students, the “everyday man” both old and young alike. Sound plays major roles in human life, from the first cry of the newborn baby to the final breath and “death rattle” of those passing. For most of us, sound encompasses our entire lives and every breathing moment. At times it is to be rejoiced, other times to be escaped (has anyone else ever asked the room, “Can everyone just be quiet for a minute please I can’t think!). It is argued that pure silence only exists in “space”. Truly, sonic vibrations are as prevalent as particles of light, moving atoms back and forth within this physical plane. There is a concept that unveils this, a belief in a natural structure that exists beyond the human world and is and embedded in the physical structure of the universe itself: the sound matrix.
Hans Jenny: Pioneer in Cymatics
The belief in a sound matrix is the idea that a pre-created and predetermined sound configuration exists innately in the universe, one that can be exposed and studied. Several scholar/scientists have contributed to this field: now known as “cymatics,” a term applied by researcher Hans Jenny (1904-1972). Essentially, he explored a myriad of different distinct patterns created when particles are placed on a plate and vibrated at different frequencies. In other words, cymatics is the study of wave phenomena that created repeatable physical patterns from the frequency sound vibration of particles. His bookCymatics: A Study of Wave Phenomenon and Vibration is the defining work to be discussed further on in this post.
The inspiration for the exploration into cymatics is steeped in “anthroposophy,” a philosophy founded by Rudolf Steiner (1861-1925), which states that human beings can intellectually access and uncover elements of an existing spiritual plane. In fact, Jenny’s own book is “Dedicated to the memory and research of Rudolf Steiner.” Anthroposophists believe that the witness of the spiritual world and its demonstration through experiments in fields such as cymatics will stand the test of rational verification. This foray into sound study is an example of the founding principle of anthroposophy and mimics the methods of the natural sciences in their practices of evidence-based research. Before Jenny, however, there are a few other individuals that paved the way for this exploration into the unseen structures embedded and surrounding us in our universe.
The beginnings of cymatics
Ideas of inherent vibrational patterns in the natural world began centuries ago, with Galileo Galilei often quoted as an early witness to the phenomena from his writings of 1632 in his “Dialogue Concerning the Two Chief World Systems.” He explains his experiences when scraping a plate of brass with a chisel, attempting to clean it. Galileo noticed both a high whistling sound and the production of parallel streaks of brass particles that only occurred in tandem with the sound. Fifty years later, scientist and musician Robert Hooke, in 1680, noticed nodal patterns created with vibrating glass. Using a violin bow on a flour covered glass plate, he produced repeated patterns. One would think today, imaging back, that both of these experimenters must have experienced something mystical. They discovered, or uncovered, a structure within the physical world not yet noted by humankind; a matrix that predates history, clearly put in place by a non-human force. No wonder their testimony has withstood the test of time.
One hundred years after Hooke’s observations, one Ernst Florence Friedrich Chladni (1756-1827) published “Entdeckungen über die Theorie des Klanges” translated to English as “Discoveries in the Theory of Sound.” Chladni was inspecting the properties of “Lichtenberg figures.” German physicist Georg Christoph Lichtenberg discovered these radial patterns in in 1777 when placing powdered material on a high-voltage plate. Chladni had the intriguing impetus to run a violin bow along a metal plate holding powder (some say sand), which created vibrations and thus arranged the particles into patterns, creating visibility to the vibrations. It’s a complex phenomenon due to wave behavior with the particles being moved from the “antinode” to the “nodal” lines, but suffice it to day – really cool patterns emerged. “Hmmm … wow, what are these fantastic shapes appearing from sound? From whence do they come?” Chladni may have asked.
A good while later, Hans Jenny whistled his own experimental tune of the 1960s and worked diligently for over a decade to create and study patterns created by vibration in the exact same vein as his predecessors. With the aid of years of technology, his vibrating method was superior to those before him in its accuracy. He used crystal oscillators and tone generators to control the frequency and amplitude of his signals as opposed to the anvil of Galileo and the bow of Chladni. Jenny connected these devices to metal plates and his methods were repeatable, a necessary condition in scientific research. Below is an example of the intricate patterns that Jenny uncovered through his work. This, in particular, is the latticework in liquid, seen in video below
Jenny’s Work and Theory
Jenny published Kymatik (translated Cymatics) in 1967 after, as mentioned, more than 10 years of intense study. When reading through his work, found at through a google search of “hans jenny cymatics pdf,” his adherence to anthroposophy is obvious as he continually attempts to connect the dots between his work and other periodic systems throughout the physical world: “Whenever we look in Nature, animate or inanimate, we see widespread evidence of periodic systems. These systems show a continuously repeated change from one set of conditions to another, opposite set”(Jenny, 17) He mentions human circulation and respiration, the cycles found within the vegetable and animal kingdoms and goes into chemistry as he sets up the argument for cymatics as a structure of the universe predating humankind: that the organization of the sound matrix is prime and found throughout all matter, and recognized throughout his work.
A colleague of his, Jeff Volk, sums up the most poignant of Jenny’s ideas succinctly in his introduction. He writes: that “the principle underlying Cymatics, that of periodicity, is so ubiquitous in nature (and in Nature), that it is found in all manner of phenomena.” Volk further reflects on how Jenny’s discoveries “mirrored biological forms and natural processes, as well as flowers, mandalas and intricate geometric designs … these experiments seemed to reveal the hidden nature of creation, to lay bare the very principle through which matter coalesces into form.” Volk The most striking of Volk’s points is that Jenny’s shapes were the result of “audible vibration.” In other words, cymatics allows us to see sound.
By carefully controlling the frequencies he generated and the area size of the metal plates, Jenny could compare various substances such as sand, fluids, and powders at different frequencies and in different areas. The vibrations had a large range which resulted in a large array of various geometric shapes. From these he noted three fundamental principles of vibration and wave motion. One pole exhibits patterns and figures which is visible. The other pole demonstrates kinetic processes (plate vibrations) which is audible. Third, the entire process is periodic, which Jenny terms “essential periodicity.” The concept of essential periodicity is significant in understanding Jenny’s mission: “essential” refers to patterns that are of the essence of the physical world, and periodicity clearly that periodic cycles are also embedded in the physical plane.
Jenny explores a wide array of different frequencies on different media resulting in a striking variety of visible patterns: square metal plates of various sizes, triangular plates with crystals attached to their underside, The images in this video begin at 2:07

The moments above and others through the video are reminiscent of other living and non-living beings and figures found in nature, clearly. I will end this post with Jenny’s own words which I’ve transcribed from the video above and shed further light and is purpose and vision on the primacy of sound:
You will see many things that answer many questions. You will see living forms, living amoeba, almost animal-like creatures, you will see continents being formed, the earth itself coming into existence, explosions, eruptions, atomic explosions and bombs, you can see all this and watch it before your eyes. But everything owes its existence solely and completely to sound. Sound is a factor which holds it together. Sound is the basis of form and shape. In the beginning was the word and the word was God. We are told this is how the world began and how creation took shape.~ Hans Jenny
Welcome to Part II of this blog discussion on David Tame’s The Secret Power of Music. Part I explained Tame’s main point of the initial part of his book. Namely, that music among the ancients, that philosophies that can be traced up to the present time, was considered an essential part of the source of the universe and a way for the divine to manifest in human beings, and for humans to spread the goodness and harmony of the universe on earth. While Tame’s book covers many aspects and variations of music across world cultures throughout time, it boils down to two conflicting musical conceptions: the divine and ordered nature of music among the ancients up to the 19th century vs. the individualistic and disordered conception and creation of music since then. The second part of Tame’s book drifts from classical music into the experimentalism of the 19th and 20th centuries and ends in discussions of jazz, “computer music,” and rock and roll. While in the end, it is rather obvious that Tame’s affection lies in the divinely inspired music of the ancients, the book in its entirety is worth understanding as it covers a broad swath of musical inventiveness.
Onward from the ancients
Tame moves from ancient China, which regarded music as an expression of “god” into the Middle Ages, Baroque, and Classical music. While he admits creativity and inventiveness throughout these ages, his main point that adheres all is that in each period music continued to be viewed as a means to promote spirituality among mankind as in the Middle Ages and/or at the very least to elevate the nature of humanity. As for the Middle Ages, music was used by the church to spread Christian ideals. During this time, the Church was the primary means of sustaining “serious music. Tame mentions the use of “plainsong,” is music sung without accompaniment, such as Gregorian chants. The liturgy was used as text for the vocals and thus religious and ideals were taught and reiterated through music. An example of plainsong:
In addition, “organum” developed on top of plainsong with the addition of a second harmonic voice. It was the beginning of polyphonic music and spread quickly throughout Europe, employed religiously in great cathedrals. In this case, the power of music was used to sway congregations toward the ideals of the Catholic church:
Both plainsong and organum inspired the subsequent classical and romantic composers to create out of altruism and ideals of sanctity. Like the ancient Chinese mentioned in Part 1, Western music was meant to inspire a connection between the human world and the greater cosmos or “God.”
Constrained but innovative in the 18th and 19th centuries
Stieler, Joseph Karl: Beethoven with the Missa solemnis Ölgemälde, 1819
From here Tame briefly covers the music of the eighteenth and nineteenth centuries. His main point is that the music of Haydn, Mozart, Bach, and Beethoven were saturated with the goal of spreading “spirituality, joy, and brotherhood.” Bach’s Brandenburg Concertos were replete with divinity in the perfect mathematical harmonies, their gorgeous melodies, and powerful rhythms that mirrored the vibrations of the greater universe. According to Tame, Mozart, as a Free Mason, ensured that Masonic symbolism and spiritual ideals were embedded in his work which culminated in the Magic Flute. Beethoven’s work, which called secular by some, is also renowned as spiritual in nature. His nine symphonies relate to transcendence and his five final string quartets understood to be mystical. Still, throughout the 19th century, the power of music continued to be used for “higher” moral purposes.
However, at the end of the nineteenth century, Tame further explains that the higher purpose of music began to go astray. The beginnings of change were brought on by experiments with technique, not a purposeful harnessing of the power of music for other purposes. Western music, though it had been used for centuries by the Church and for “morality” nevertheless did not have a code requiring musicians to play only certain music, as did the ancients. Therefore, over time, innovations occurred, led by the likes of Bach, Beethoven, and Wagner. Their musical experiments were met with criticism and Tame mentions Beethoven’s Grosse Fuge as a target of tradition. He created alternative parts to sway the critics and only after many decades that his avant-garde work was appreciated. During this time, composers introduced new instruments, increased rhythmic complexity, used tones more freely and modulated freely, though still obeying traditional rules of tonality. Wagner did modulate himself into a freedom from key in his later works as Tame notes.
The 20th century unleashes a new understanding: Art for art’s sake
The Secret Power of Music undergoes a major shift at this point as it delves into the musical developments of the 20th century. At this point, Tame states that composers no longer created music with a philosophical or moral purpose. But, instead, had different artistic reasons to create. Music was now drifting away from it’s spiritual based moorings and instead focused on the mental, emotional, and even physical elements of human experience. Human intellectualism began to replace the sacred math and spiritual symbolism of the past. Instead of experimenting to improve the quality of their music, the great age of experimentation began, experimenting for its own sake. Tame describes the “vertical” line of music in the past, from human to the heavens, as being replaced with a “horizontal” line from human to human. Here Tame covers one of the first realist composers Mussorgsky (1839-81) who emphasized connecting with the “people,” the real world of mankind. Tame likens him to the 19th century Jack Kerouac, a beat poet who emphasized individualism and a lack of rules. Tchaikovsky is mentioned next as a tortured artist due to his homosexuality (apparently according to Tame) who further expressed the personal emotions of anguish in his music. And, through him, we reach Igor Stravinsky and his Rite of Spring, which is heralded as revolutionary. The main focus when studying this work is academic, which Tame bemoans as lacking any sense of spirituality. At this point, the author seems to be implying that all sense of the “true power” of music has been stripped away.
The caging of music
Unsurprisingly, the book turns to perhaps the most influential 20th-century composer, John Cage (1912- ). Tame describes the power of Cage’s musical efforts – his plethora of produced sounds, his prominence and length of his career, the sub-movements he inspired, and Cage’s own philosophy as the “arch-enemy of spiritual idealism.” Undeniable, Cage took the creation of music to never before considered and unforeseen levels. His first renowned work, Imaginary Landscape No.1 (1939) is a composition for “for records of constant and variable frequency, large Chinese cymbal and string piano.” This piece marks a great departure from past orchestral compositions in that it was not meant to be played live, rather recorded and broadcast, and it only required four people rather than a full orchestra. The composition is six minutes in duration with one movement. Two performers controlled turntables of variable-speed, one a muted piano, and one a Chinese cymbal at a constant tempo (another variation from music of the past which utilized changes in tempo.)
Cage of course continued to experiment and actively worked to deconstruct musical notions of the past. In the 1942 Credo In Us Cage required the use of a record player that would play a classical piece in tandem with jazz or other contemporary music. The performer was required to lift the needle from time to time, chopping apart the classical piece throughout. During the 1940s, Cage fully introduced the “prepared piano.” These pianos were altered by placing objects inside, resting on strings which included pieces of wood, nuts and bolts and other hardware. For this he is most famously known. Cage also reveled in composing by chance, using dice and alter computer-generated randomness. Cage himself deserves, of course, an entire book, surely have been written.
At this point, I can lend a story of my own. Yes me, the author of this blog. In college I was fortunate enough to witness a performance of a Cage piece at the Kennedy Center in Washington DC. My music theory professor brought us there as he knew it could be our only change to ever see Cage speak, as he was there that evening. There are two are distinct moments that I remember. One, Cage recalled a mishap on stage once in which he was too near a massive speaker which suddenly emitted massive feedback and he lost his hearing for a few days. When asked how he felt about the experience, Cage said something akin to: “Wonderful, I got to hear a really really loud sound.” The second moment was during the Q&A when a music student asked Cage if he had any advice for an aspiring composer to which he replied, “You have to love sound. You have to love sound with your whole heart.” That is the power of music, in all it’s deafening force and all of its allure.
Throughout The Secret Power of Music, it becomes apparent where Tame stands. While his book is an excellent and detailed explanation of the evolution of music, he criticism of revolutionary thought in the 20th century falls a bit flat. While Tame attempts to paint 20th century music as some sort of fall from grace, a tumbling of human morality away from the divine, it is clear that Tame’s own biases shine through.
Artists draw inspiration from everything. The entire world around them and the human relationships they have are all sources of experience that provide the meaning they need to express. One powerful source of expression for the visual art is sound and music, the topic of this post. Below are some beautifully intricate creations inspired by the sonic world.
Luke Jerram’s Aeolus
Luke Jerram is a multidisciplinary artist who creates live art projects, sculptures and installations internationally, with over 300 exhibitions worldwide in 43 countries since 1998. His work is impressive in scope and beauty. One piece, Aeolus, was inspired by acoustics and its relationship to light, architecture, and wind. As stated on his website, Jerram’s initial idea for this project was from an interaction he had with a well digger of the Qanat desert in Iran. The well digger gave accounts of the wells singing when wind passed through them. This intriguing story motivated Jerram to explore the interaction of architecture and sound.
Aeolus is a Greek God, the keeper of the winds, and King of the island of Aeolia. He gave Odysseus and his crew a favourable wind to aid in their return to their home in Ithaca and his legacy is clearly an apt name. Jerram calls Aeolus an acoustic wind pavilion. The design of this massive stringed instrument amplifies the sound of shifting wind as well as the visual aspect of the sky as it changes. Built as a giant aeolian harp, the structure resonates on its own without additional power. According to the wind, strings attached to tubes vibrate which reverberate on skins at the top. These sound waves are sent via the tubes down to the viewers below. Aeolian harp strings are webbed throughout the structure, delicately sensitive to the wind and give an auditory interpretation of the wind in three dimensions to the viewer/listener, which Jerram writes is a “shifting wind map.” Beyond that, the tubes without strings are tuned to the aeolian scale and constantly hum even without wind.
In addition to the acoustic element, Jerram placed a great emphasis on the optical nature of Aeolus. 310 “internally polished stainless steel tubes” are placed so that the viewer can look through them, reflecting the shifting sun. This creates a continuously changing “landscape of light” as the steel tubes magnify and invert the area around the structure. The shifting skylight, acted upon by clouds and the sun, creates a dramatic picture in constant motion. The Institute of Sound and Vibration Research at the University of Southampton and The Acoustics Research Centre at the University of Salford were collaborators.
Dentsu Sound Sculptures
This next mention is a stunning display of sound energy turned into art. Not only inspired by sound, but created by sound, ad agency Dentsu London worked with biochemist-photographer Linden Gledhill and photography Jason Tozer to capture sound displayed in paint. Appropriately, the project was for the Canon PIXMA color printer and the results of the project unique and ultra-vibrant. The concept of placing objects on speakers has been used, through the results in this case with the addition of high speed photography, give a special view into the physics of sound. Here, paint was placed on a cover over a vibrating speaker. While the resulting paint movements were only several cm high, the high speed photography yielded gorgeous colorscapes and unique shapes in this interplay of sound and paint.
In the video “Bringing colour to life” above, Cannon Account Director Rob Zuurbier explains that the project is a celebration of color meant to highlight the “great quality of prints that the Canon Pixma produces.” The goal of the campaign was to revitalize Cannon’s image, so to speak, and this writer would say its quite successful as they were able to create other-worldly shapes using craft and
cutting-edge technology. The video shows a what appears to be a rubber membrane wrapped around a small speaker. Speakers in the video explain that photographs were taken at the incredible speed of 5,400 frames per second. A multitude of colors were used, resulting in some figures having hundreds of shades of color. The technological feat is impressive as they had less than a millimetre of depth to focus on a frame 4-5 feet in diameter.
Water sound sculpture by brusspup
In this demonstration of sonic sculpture, youtube user bruspup uses a speaker, a rubber hose, water, tone generating software producing a 24hz sine wave, and a 24 fps camera to send vibrations to pouring water, resulting in some surprising shapes. Brusspup secures the hose to a speaker simply with duct tape so that the speaker’s vibrations will be transferred to the hose and thus the water Next, he produces a 24Hz sine wave through the speaker and turns on the water.
Towards the end of the video, brusspup demonstrates the 25Hz forward effect and the 23Hz reverse effect, which makes the water appear as if it is either spiralling forward (downward) or in reverse (upwards) while flowing down. This visual is not a result of the sound waves passing through the water, but rather of the camera speed in relation to the Hz produced. In order to achieve the forward effect, one bumps up the Hz of the sound to 25Hz for forward and down to 23Hz for reverse as explained by Dan Nosowitz on popsci.com. All sorts of strange things happen between the interplay of the visual, time, and sound when the camera rate is changed. Sound designers certainly are familiar with the necessity of matching sample rate with video, ensuring that 48Khz audio is used for 48Khz video. Other, the sound and picture very quickly become entirely off. Either way, Brusso’s experiment and demonstration is an efficient and artful way of showing the potential between vibration and sculpture. Another intriguing element is the spiral itself. Perhaps the ratio in its spiral is the same as the mysterious Fibonacci sequence found throughout nature?
Benoit Maubrey: Speaker’s Wall
”An artist’s job is to interpret reality. Instead of using pigment on canvas, you can imagine the air is the canvas and the pigment is the sound, so you’re out there painting canvases.” – Benoit Maubery (mvtjournal.com)
Benoit Maubrey is an American electroacoustic sculptor who combines three-dimensional space with sound across a wide array of the arts including performance, sculpture, dance, sound, and the technological arts. He specializes in manifesting public sculptures, interactive in nature, that use cheap, recycled, and found electronics. The electronics are active which lend to interactivity and a performance element.
An entire book could be written on the intricacies and unique vision of his work, but the focus here is Speaker’s Wall.
This project was inspired by an art competition in West Berlin in 1987 entitled “Overcoming the Wall by Painting the Wall.” In the New York Times archives, an article from the Berlin Journal; In Search of a Work of Art to Overcome the Wall by Serge Schemann from 1987 describes the art movements of the time on the West Berlin side protesting the existence of the wall and totalitarianism in general. As stated by German artist Peter Unsicker, the wall is “built by Germans in the East, painted by Germans in the West.” Multitudes of artists at the time were inspired to paint and sculpt on or around the wall, mocking and heavily criticizing the Soviet Union and East German governments. Confronted by this physical presence and the horrors it symbolized, artists mobilized for this 1987 competition and protest festival. Speaker’s Wall won second place and is now part of the permanent collection of Museum Haus at Checkpoint Charlie in Berlin, Germany. The work is an impressive combination of not only various fields of art but also the politics of the time and its significant messages of freedom vs. captivity. Maubrey’s work certainly captivates attention.
The electroacoustic sculpture uses 1000 recycled loudspeakers, amplifiers, and radios. Incredibly, callers can phone the sculpture and talk through it. During the exhibition, more than 900 calls were made. In addition, at the time it also served as a PA system. Maubrey has a myriad of similar, but equally original, sculptures listed on his site. Another sculpture that can be physically called is the Speaker’s Monument, exhibited in 1991 in the West Berlin Exhibition, Riga, Lithuania. Maubrey recycles a trashed Stalinist sculpture “Heroes of the Working Class” into a speaker system that accepts calls. The work is covered with loudspeakers, a telephone answering machine and an amplifier. Again this artist meshes art, sound, and live political performance via the callers.
The artists above demonstrate that sound is not only a powerful medium in and of itself, but its power extends into other art forms with ease.
Sound is a force of nature that has its own special and unique properties. It can used artistically to create music and soundscapes and is a vital part of human and animal communication, allowing us to develop language and literature, avoid danger, and express emotions. In addition, understanding and harnessing the unique properties of sound has resulted in some surprising and fascinating inventions and technologies. Below are some interesting notes on the behavior of sound and some novel technological uses, both as a weapon and in contrast in medicine and health care.
The Speed of Sound
Sound exists when its waves reverberate through objects by pushing on molecules that then push neighboring molecules and soon. The speed at which sound travels is interesting as it behaves in the opposite manner of liquid. While the movement of liquid slows down depending on the density of the material it is trying to pass through, for example cotton as opposed to wood, sound actually speeds up when faced with denser material. For example,sound travels in Air (21% Oxygen, 78% Nitrogen) at 331 m/s, 1493, m/s through water, and a whopping 12,000 m/s through Diamond.
This sound behavior is also evident in how quickly it can pass through the human body, which is generally around 1550 m/s, but passes much more quickly through skull bone at 4080 m/s which is much denser then soft tissue. Interestingly, the average speed through the human body is very similar to that of water, which makes sense because human beings are 90% made up of water.
Sound in a Vacuum
Not only does the density of objects increase the speed ofsound, sound needs material to be present in order to “make sound” inthe first place. Because, it exists when sound waves reverberate through objects. Without objects present, sound does not exist, such as is a vacuum. his makes as a vacuum is an area of space that is completely avoid of matter and therefore has no molecules. This video demonstrates the effect of a vacuum on sound. As the air is sucked out of the bell jar, the bell can no longer be heard.
Sound is in the Ear of the Earholder
For humans and animals, the perception of sound waves passing through their ears, depends on the shape of the ear, which influences that vibrations. The shape of an animal’s outer ears determine the range of frequencies that they can hear. Elephants have flat and broad ears, which allowthem to hear very low frequencies, which they use to communicate. Lower frequencies are associated with large surface areas, such as bass drums, so this makes sense. Mice have ears that are round, which allow them sensitivity to sounds that come from above. Again, this makes sense as they are tiny and close to ground and all threats would be coming from above: hawks wanting to
eat, cats hunting, humans screaming and jumping on chairs, etc. The tall ears of rabbits make them sensitive to sounds flying around horizontally, obviously so they know when to jump. Owls work their famous head pivot to create a precise sound listening experience while checking for prey and threats. Deer work to avoid predators with muscles in their ears that allow them to point in different directions.
Sound as a Weapon
The Long Range Acoustical Device (LRAD) is a machine used to send messages and warnings over very long distances at extremely high volumes by law enforcement, government agencies, and security companies. They are used to keep wildlife from airport runways and nuclear power facilities. The LRAD is also used for non-lethal crowd control. It is effective in crowd control because of its very high decibel range which can reach 162. This exceeds the level of 130 decibels, which is the threshold for pain in humans. It is very precise and can send a “sound beam” between 30 and 60 degrees at 2.5kHZ and will scatter crowds that are caught within the beam. Those standing next to it or behind it might not hear it at all. But those who do report feeling dizzy with symptoms of migraine headaches. This is called acoustic trauma and depending on the length of the exposure and it’s intensity, damage to the eardrum may result in hearing loss. Since 2000, the LRAD has been used in many instances of crowd control throughout countries in the world, and even on pirates attempting to attack cruise ships.
Almost humorously, high pitched alarms can also be used to deter teenagers from loitering around shops or engaging in vandalism and drug activity. The “teenage repellant” has been used throughout Europe and the US. Since teenagers have a higher frequency range of hearing than adults, it targets them specifically, while adults are spared the annoyance of the 17.4KHz emission. There are critics that state these devices unfairly target specific groups (youth) and are therefore discriminatory.
Sound levitation, or acoustic levitation, uses sound properties to allow solids, liquids and gases to actually float. It uses sound wave vibrations that travel through gas to balance out the force of gravity and creating a situation in which objects can be made to float. Dating back to the 1940s, the process uses ultrasonic speakers to manipulate air pressure and points in the sound wave that counteracts the force of gravity. A “standing wave” is created between a “transducer,” such as a speaker and a reflector. The balancing act occurs when the upward pressure of the sound wave exactly equals the force of gravity. Apparently the shape of liquid such as water can be changed by altering the harmonics of the frequencies that result in star shaped droplets.
In terms of practical uses of sound levitation, they do improve the development of pharmaceuticals. When manufacturers create medicines they fall into two categories called amorphous and crystalline. The amorphous drugs are absorbed into the body more efficiently than crystalline drugs. Therefore, amorphous are ideal because a lower does can be used so they are cheaper to create. So, during evaporation of a solution during manufacturing, acoustic levitation is because it helps prevent the formation of crystals because the substance does not touch any physical surfaces. Acoustic levitation, in others words stops substances from crystallizing, thus creating a much more efficient method of drug creation. In addition, sound levitation creates essentially a zero-gravity environment and is therefore an excellent environment for cell growth. Levitating cells makes sure that a flat shape is maintained which is the best for the growing cell to absorb nutrition. It could also be used to create cells of the perfect size and shape for individuals.Sound behaves in its own fashion and is a phenomenon that can be used in force and in healing. It taps into the physics of the natural world and through its interaction allows for all sorts of human invention. Surely, sound will continue to be researched and pursued as a powerful natural element to be used in a myriad of new ways.
Traditionally, post-secondary education in Western culture for years has been hinged on both parents and students desiring education that “rounds out” the student’s mind, ie a “liberal education.” This concept of the liberal education still commands the trajectory of many high-achieving students who graduate high school in the US, and gymnasium in Europe. The goal, as many still believe, is to then attend an expensive college or university to learn the higher concepts of Western academics: philosophy, literature, history, and the social sciences. However,
as the world changes based on obvious technological advances involving computing, the internet, and digital production, there are now new choices for those students and families who choose not to adhere to the beaten path.
Simply put: there are now more
choices to post-secondary education and one path is sound and music and media
production.This is a good thing.
Two schools, one in the United States, and one in the United Kingdom, exemplify this forward motion into the future of post-secondary education by emphasizing education based on media production, and de-emphasizing traditional courses in Western philosophy, for example, Shakespeare. The two schools covered below offer real degrees or certificates and more importantly, practical career benefits upon graduation. They differ somewhat in their approaches, degrees, and course selection, but are similar in their intent: to provide pragmatic post-secondary education to talented and creative young adults who are intent on pursuing creative passions while earning real incomes after graduation. The two schools covered below are Full Sail University in the United States and the Point Blank School in the United Kingdom and this article simply intends to lay out the presentations and claims of both for any student seeking a higher education in sound and media production. The contrast between the two is rather striking. However, both are sound, no pun intended. Simply put, for readers heading toward a career in sound, music, and media, both schools are worthwhile, high quality, and have a track record of success among their alumni.
Full Sail University is located in Winter Park, Florida in the United States and bolsters an interesting and vibrant history. The inception of the school began in 1979, as a recording workshop called “Full Sail Recording Workshop” in Dayton, OH, by a Mr. John Phelps. Throughout the years, driven by student interest and teaching success, the school now commands a 192 acre campus with 49 degree programs and 2 graduate certificates which include nearly every form of digital media production avenue available to future digital media content providers. They provide degrees in music and recording (including studies in sound recording and design), games, art and design, technology, media and communications, art and design, and media and sports business.
There is credence to their degrees. They are licensed by the Commission for Independent Education (Florida Department of Education) to offer Associates through Masters degrees. They are also accredited by the Accrediting Commission of Career Schools and Colleges (ACCSC), an organization that is recognized as a national accrediting school by the U.S. Department of Education. Meaning, and this is very important for students who desire a valid BA, Full Sail provides degrees that will be recognized by other schools in the United States if a student may want to achieve a Masters Degree in Sound Design or other media discipline at another university or college in the United States. In addition, their Bachelor programs are efficient and can be completed in 20 to 29 months. Programs begin monthly and therefore there is no need to wait through semesters of time to begin studying. Many of us perhaps remember slogging through low paying jobs during summers waiting for school to begin. This waste of time does not happen at Full Sail. Graduation for the hard working student can come in half the time of a traditional 4-year college. This will give any graduate an edge in entering the workplace at younger age than their peers, ready and prepared for their career possibilities of the future.
In addition to their massive array of course offerings in multiple media disciplines, Full Sail functions as a proper university, providing financial aid and housing options near the campus. Upon graduation, they provide assistance for career development and work on job placement. They use a unique combination of technology such as networking with classmates and easy access to instructors online, continuous technical support, video conferencing, the ability to create via laptops from anywhere at anytime, and the use of cutting-edge media creation software to teach multi-media production. They couple this effective use of technology with the traditional model and rigors of a 4-year bachelors, requiring many hours of study and a wide array of courses needed to earn a degree. In all, Full Sail appears to provide a solid education in a wide array of media disciplines and the school and staff work diligently to aid their students in careers after graduation. One quick glance at their Alumni page attests to the success of their graduates, who work in film and sound capacities with the top media production firms throughout the world. This school is a valid option for students passionate and interested in media production.
The second school mentioned in this post, is the Point Blank School, an Electronic Music School that teaches music production and performance skills and techniques in London, England, Los Angeles, US, Ibiza, Spain, and online. At the onset here, one must agree that it would be hard for anyone interested in music production not to salivate at the possibility of attending a campus to study electronic music on the island of Ibiza. This would be a young DJ’s heaven. On the island of Ibiza, specifically, it appears that students study by day and then at night are given the opportunity to rub elbows with highly successful DJ’s and are afforded the opportunity to perform at internationally renowned nightclubs on the island. This sounds like a win-win for those who can afford to attend. Regardless of the three locations, it is clear that Point Blank is a successful electronic music school that attracts globally successful DJ’s and producers as instructors and most likely is helping to create the next generation of electronic music producers. On an academic note, Point Blank School has a an affiliation with Middlesex University, which validates their Higher Education classes and those who complete the Point Blank set of courses receive a certificate and award upon completion. Middlesex apparently also “validates” the BA Music Production & Sound Engineering program.
To sum it up, both Full Sail and Point Blank provide top-notch media production education. The location in which you live may determine your preference. Clearly, if you are in the United States, then Full Sail is more accessible and if you are in Europe then Point Blank is the closer option. Full Sail has a longer history and a vastly larger set of course offerings. They have managed to achieve accreditation as a “four year” university that bestows actual BA’s that in theory will transfer to other schools. The programs are steeped in a wide array of disciplines and many of their students move into the media industry with great success. For the youngster graduating high school in the US, or those willing to trek across the pond and can afford it, Full Sail is a valid, excellent alternative to the traditional liberal arts education and provides not only electronic sound and music production, but video arts and other media productions fields as well. They also have, which has not been mentioned yet in this article, a massive film set/lot where Hollywood sized films can be created. They command one singular massive campus with a four year college degree experience.In comparison and contrast, Point Blank is equally passionate and active in their own realm. Their realm is more singular however, catering to the world of elite DJ-ing and production and focusing on electronic music production and performance only. Clearly, the school has succeeded in attracting excellent talent to instruct and built campuses in three of the most illustrious places in the world (London, Los Angeles, Ibiza) to be an electronic music artist. Clearly their combination of talented instructors, course layout, and very importantly the exposure for current students to the club scenes of their various locations, are all major pluses. It depends on what one’s goals are as an aspiring sound/media artist and the degree you would like to have upon your graduation. Full Sail will give you legitimate academic credentials, serious professional contacts, a community, and support. On the other hand, Point Blank will give you expert skills for rocking dance floor, a certificate and perhaps a BA. Mostly, though, it seems it will give you high level contacts and experience in the world of globally recognized DJ’s. Both schools rock. Hats off.
