Sounding Out! Podcast #34: Sonia Li’s “Whale”

This slideshow requires JavaScript.





Reflecting on Whale, an interactive, multichannel sound installation, this sound art piece documents how the installation came about. When designing Whale, Sonia Li used sound to communicate the often visceral emotions underlying her personal narrative.

Whale creates an environment where one experiences oneself. By laying in darkness on a subsonic vibrating bed, users openly confess their thoughts and feelings into a sonic field, which then translates their words into correlating amplitudes of whale sounds. This process of transduction prompts listeners to consider how sound works to shape a perception of themselves as they hear a distant and alien rendering of their own voice. By experiencing Whale we can consider how sound challenges our physiological and psychological perceptions of self.

Sound and Pleasure2After a rockin’ (and seriously informative) series of podcasts from Leonard J. Paul, a Drrty South banger dropped by SO! Regular Regina Bradley, a screamtastic meditation from Yvon Bonenfant, a heaping plate of food sounds from Steph Ceraso,  and crowd chants courtesy of  Kariann Goldschmidts work on live events in Brazil, our summer Sound and Pleasure comes to a stirring (and more intimate) conclusion.  Tune into Justyna Stasiowskas frequency below. And thanks for engaging the pleasure principle this summer!--JS, Editor-in-Chief

One of my greatest pleasures is lying in bed, eyes closed and headphones on. I attune to a single stimuli while being enveloped in sound. Using sensory deprivation techniques like blindfolding and isolating headphones is a simple recipe for relaxation, but the website Digital Drugs offers you more. A user can play their mp3 files and surround themselves with an acoustical downpour that increases and then develops into gradient waves. The user feels as if in a hailstorm, surrounded by this constant gritty aural movement. Transfixed by the feeling of noise, the outside seems indistinguishable from inside.

Sold by the i-Doser company, Digital Drugs use mp3 files to deliver binaural beats in order to “simulate a desired experience.” The user manual advises lying in a dark and silent room with headphones on when listening to the recording. Simply purchase the mp3, and fill the prescription by listening. Depending on user needs, the experience can be preprogrammed with a specific scenario. This way users can condition themselves using Digital Drugs in order to feel a certain way. The user can control the experience by choosing the “student” or “confidence” dose suggestive of whether you’d like your high like a mild dose of marijuana or an intense dose of cocaine. The receiver is able to perceive every reaction of their body as a drug experience, which they themselves produced. The “dosing” of these aural drugs is restricted by a medical warning and “dose advisors” are available for consultation.

Thus, the overall presentation of Digital Drugs resembles a crisscross of medicine and narcotic clichés with the slogan “Binaural Brainwave doses for every imaginable mood.” While researching the phenomena of Digital Drugs, I have tried not to dismiss them as another gimmick or a new age meditation prop. Rather, I argue the I-Doser company offers a simulation of a drug experience by using the discourse of psychoactive substances to describe sounds: the user becomes an actor taking part in a performance.

By tracing these strategies on a macro and micro scale I show a body emerging from a new paradigm of health. I argue that we have become a psychosomatic creature called the inFORMational body: a body that is formed by information, which shapes practices of health undertaken to feel good and form us. This body is networked, much like a fractal, and connects different agencies operating both in macro (society) and micro (individual) scales.

Macroscale Epidemy: The Power of Drug Representation 

Heinrich Wilhelm Dove described binaural beats in 1839 as a specific brain stimuli resulting in low-frequency pulsations perceivable when two tones at slightly different frequencies are presented separately through stereo headphones to each of the subject’s ears. The difference between tones must be relatively small, only up to 30 Hz, and the tones themselves must not exceed 1000 Hz. Subsequently, scientific authorities presented the phenomena as a tool in stimulating the brain in neurological affliction therapy. Gerard Oster described the applications in 1968 and the Monroe Institute later continued this research in order to use binaural beats in meditation and “expanding consciousness” as a crucial part of self-improvement programs.

I-Doser then molded this foundational research into a narrative presenting binaural beats as a brain stimulation for a desired experience. The binaural beats can be simply understood as an acoustic phenomena with application in practices like meditation or medical therapy.

I-Doser also employs the unverified claims about binaural beats into a narration that consists of the scattered information about research; it connects these authorities with YouTube recordings of human reactions to Digital Drugs. Video testimonies of Digital Drugs users caused a considerable stir among both parents and teachers in American schools two years ago. An American school even banned mp3 players as a precautionary measure. In the You Tube video one can see a person lying with headphones on. After a while we see an involuntary body movement that in some videos might resemble a seizure. Losing control over one’s body becomes the highlight of the footage alongside a subjective account also present in the video. The body movements are framed as a drug experience both for the viewer who is a vicarious witness and the participant who has an active experience.

This type of footage as evidence was popularized as early as the 1960s when military footage showed reactions to psychoactive substances such as LSD.

In the same manner as the Digital Drugs video, the army footage highlights the process of losing control over one’s body, complete with subjective testimonies as evidence of the psychoactive substance’s power.

This kind of visualization is usually fueled by paranoia, akin to Cold War fears, depicting daily attacks by an invisible enemy upon unaware subjects. The information of the authority agencies about binaural beats created a reference base that fueled the concern framing the You Tube videos as evidence of drug experience. It shows that the angst isn’t triggered by technology, in this case Digital Drugs, but by the form in which the “invisible attack” is presented: through sound waves. The manner of framing is more important than the hypothetical action itself. Context then changes recognition.

Microscale Paradigm Shift: Health as Feeling 

On an individual level, did feeling better always mean being healthy? In Histoire des pratiques de santé. Le sain et le malsain depuis le MoyenAge, Georges Vigarello, continuator of the Foucault School of Biopolitics, explains that well-being became a medicalized condition in the 20th century with growing attention to mental health. Being healthy was no longer only about the good condition of the body but became a state of mind; feeling was important as an overall recognition of oneself. In the biopolitical perspective, Vigarello points out, health became more than just the government’s concern for individual well-being but was maintained by medical techniques and technologies.

In the case of Digital Drugs the well-being of children was safely governed by parents and media coverage creating prevention in schools from the “sound drugs.” Similarly, the UAE called for a ban on “hypnotic music” citing it as an illegal drug like cannabis or ecstasy. Using this perspective, I would add that feeling better, then, becomes a never-ending warfare; well-being becomes understood as a state (as in condition and as in governed territory).

Well-being is also an obligation to society, carried out by specific practices. What does a healthy lifestyle actually mean? Its meaning includes self-governance: controlling yourself, keeping fit, discipline (embodying the rules). In order to do it you need guidance: the need for authorities (health experts and trainers) and common knowledge (the “google it” modus operandi). All of these agencies create a strategy to make you feel good every day and have a high performance rate. Digital Drugs, then, become products that promise to boost up your energy, make you more endurable, and extend your mind capabilities. High performance is redefined as a state that enables instant access to happiness, pleasure, relaxation.

inFORMational Body 

Vigarello reflects that understanding health in terms of low/high performance—itself based on the logic of consumption—created the concept of a limitless enhancement. Here, he refers to the information model, connecting past assumptions about health with a technique of self-governing. It is based on senses and an awareness of oneself using “intellectual” practices like relaxation and “probing oneself” (or knowing what vitamins you should take). The medical apparatus’s priority, moreover, shifted from keeping someone in good health to maintaining well-being. The subjective account became the crucial element of a diagnosis, supporting itself on information from different sources in order to imply the feeling of a limitless “better.” This strategy relies strongly on the use of technologies, the consideration of a sensual aspect and self-recognition—precisely the methodology used for Digital Drugs’ focus on enhancing wellbeing.

Still, this inFORMational body needs a regulatory system. How do we know that we really feel better? Apart from the media well-being campaign (and the amount of surveillance it involves), we are constantly asked about our health status in the common greeting phrase, but its unheimlich-ness only becomes apparent for non-anglo-saxon speakers. These checkpoint techniques become an everyday instrument of discipline and rely on an obligation to express oneself in social interactions.

So how do we feel? As for now, everything seems “OK.”

The Better to Hear You With, My Dear: Size and the Acoustic World


Hearing the Unheard IIToday the SO! Thursday stream inaugurates a four-part series entitled Hearing the UnHeard, which promises to blow your mind by way of your ears. Our Guest Editor is Seth Horowitz, a neuroscientist at NeuroPop and author of The Universal Sense: How Hearing Shapes the Mind (Bloomsbury, 2012), whose insightful work on brings us directly to the intersection of the sciences and the arts of sound.9781608190904

That’s where he’ll be taking us in the coming weeks. Check out his general introduction just below, and his own contribution for the first piece in the series. — NV

Welcome to Hearing the UnHeard, a new series of articles on the world of sound beyond human hearing. We are embedded in a world of sound and vibration, but the limits of human hearing only let us hear a small piece of it. The quiet library screams with the ultrasonic pulsations of fluorescent lights and computer monitors. The soothing waves of a Hawaiian beach are drowned out by the thrumming infrasound of underground seismic activity near “dormant” volcanoes. Time, distance, and luck (and occasionally really good vibration isolation) separate us from explosive sounds of world-changing impacts between celestial bodies. And vast amounts of information, ranging from the songs of auroras to the sounds of dying neurons can be made accessible and understandable by translating them into human-perceivable sounds by data sonification.

Four articles will examine how this “unheard world” affects us. My first post below will explore how our environment and evolution have constrained what is audible, and what tools we use to bring the unheard into our perceptual realm. In a few weeks, sound artist China Blue will talk about her experiences recording the Vertical Gun, a NASA asteroid impact simulator which helps scientists understand the way in which big collisions have shaped our planet (and is very hard on audio gear). Next, Milton A. Garcés, founder and director of the Infrasound Laboratory of University of Hawaii at Manoa will talk about volcano infrasound, and how acoustic surveillance is used to warn about hazardous eruptions. And finally, Margaret A. Schedel, composer and Associate Professor of Music at Stonybrook University will help readers explore the world of data sonification, letting us listen in and get greater intellectual and emotional understanding of the world of information by converting it to sound.

– Guest Editor Seth Horowitz

Although light moves much faster than sound, hearing is your fastest sense, operating about 20 times faster than vision. Studies have shown that we think at the same “frame rate” as we see, about 1-4 events per second. But the real world moves much faster than this, and doesn’t always place things important for survival conveniently in front of your field of view. Think about the last time you were driving when suddenly you heard the blast of a horn from the previously unseen truck in your blind spot.

Hearing also occurs prior to thinking, with the ear itself pre-processing sound. Your inner ear responds to changes in pressure that directly move tiny little hair cells, organized by frequency which then send signals about what frequency was detected (and at what amplitude) towards your brainstem, where things like location, amplitude, and even how important it may be to you are processed, long before they reach the cortex where you can think about it. And since hearing sets the tone for all later perceptions, our world is shaped by what we hear (Horowitz, 2012).

But we can’t hear everything. Rather, what we hear is constrained by our biology, our psychology and our position in space and time. Sound is really about how the interaction between energy and matter fill space with vibrations. This makes the size, of the sender, the listener and the environment, one of the primary features that defines your acoustic world.

You’ve heard about how much better your dog’s hearing is than yours. I’m sure you got a slight thrill when you thought you could actually hear the “ultrasonic” dog-training whistles that are supposed to be inaudible to humans (sorry, but every one I’ve tested puts out at least some energy in the upper range of human hearing, even if it does sound pretty thin). But it’s not that dogs hear better. Actually, dogs and humans show about the same sensitivity to sound in terms of sound pressure, with human’s most sensitive region from 1-4 kHz and dogs from about 2-8 kHz. The difference is a question of range and that is tied closely to size.

Most dogs, even big ones, are smaller than most humans and their auditory systems are scaled similarly. A big dog is about 100 pounds, much smaller than most adult humans. And since body parts tend to scale in a coordinated fashion, one of the first places to search for a link between size and frequency is the tympanum or ear drum, the earliest structure that responds to pressure information. An average dog’s eardrum is about 50 mm2, whereas an average human’s is about 60 mm2. In addition while a human’s cochlea is spiral made of 2.5 turns that holds about 3500 inner hair cells, your dog’s has 3.25 turns and about the same number of hair cells. In short: dogs probably have better high frequency hearing because their eardrums are better tuned to shorter wavelength sounds and their sensory hair cells are spread out over a longer distance, giving them a wider range.

Then again, if hearing was just about size of the ear components, then you’d expect that yappy 5 pound Chihuahua to hear much higher frequencies than the lumbering 100 pound St. Bernard. Yet hearing sensitivity from the two ends of the dog spectrum don’t vary by much. This is because there’s a big difference between what the ear can mechanically detect and what the animal actually hears. Chihuahuas and St. Bernards are both breeds derived from a common wolf-like ancestor that probably didn’t have as much variability as we’ve imposed on the domesticated dog, so their brains are still largely tuned to hear what a medium to large pseudo wolf-like animal should hear (Heffner, 1983).

But hearing is more than just detection of sound. It’s also important to figure out where the sound is coming from. A sound’s location is calculated in the superior olive – nuclei in the brainstem that compare the difference in time of arrival of low frequency sounds at your ears and the difference in amplitude between your ears (because your head gets in the way, making a sound “shadow” on the side of your head furthest from the sound) for higher frequency sounds. This means that animals with very large heads, like elephants, will be able to figure out the location of longer wavelength (lower pitched) sounds, but probably will have problems localizing high pitched sounds because the shorter frequencies will not even get to the other side of their heads at a useful level. On the other hand, smaller animals, which often have large external ears, are under greater selective pressure to localize higher pitched sounds, but have heads too small to pick up the very low infrasonic sounds that elephants use.

But you as a human are a fairly big mammal. If you look up “Body Size Species Richness Distribution” which shows the relative size of animals living in a given area, you’ll find that humans are among the largest animals in North America (Brown and Nicoletto, 1991). And your hearing abilities scale well with other terrestrial mammals, so you can stop feeling bad about your dog hearing “better.” But what if, by comic-book science or alternate evolution, you were much bigger or smaller? What would the world sound like? Imagine you were suddenly mouse-sized, scrambling along the floor of an office. While the usual chatter of humans would be almost completely inaudible, the world would be filled with a cacophony of ultrasonics. Fluorescent lights and computer monitors would scream in the 30-50 kHz range. Ultrasonic eddies would hiss loudly from air conditioning vents. Smartphones would not play music, but rather hum and squeal as their displays changed.

And if you were larger? For a human scaled up to elephantine dimensions, the sounds of the world would shift downward. While you could still hear (and possibly understand) human speech and music, the fine nuances from the upper frequency ranges would be lost, voices audible but mumbled and hard to localize. But you would gain the infrasonic world, the low rumbles of traffic noise and thrumming of heavy machinery taking on pitch, color and meaning. The seismic world of earthquakes and volcanoes would become part of your auditory tapestry. And you would hear greater distances as long wavelengths of low frequency sounds wrap around everything but the largest obstructions, letting you hear the foghorns miles distant as if they were bird calls nearby.

But these sounds are still in the realm of biological listeners, and the universe operates on scales far beyond that. The sounds from objects, large and small, have their own acoustic world, many beyond our ability to detect with the equipment evolution has provided. Weather phenomena, from gentle breezes to devastating tornadoes, blast throughout the infrasonic and ultrasonic ranges. Meteorites create infrasonic signatures through the upper atmosphere, trackable using a system devised to detect incoming ICBMs. Geophones, specialized low frequency microphones, pick up the sounds of extremely low frequency signals foretelling of volcanic eruptions and earthquakes. Beyond the earth, we translate electromagnetic frequencies into the audible range, letting us listen to the whistlers and hoppers that signal the flow of charged particles and lightning in the atmospheres of Earth and Jupiter, microwave signals of the remains of the Big Bang, and send listening devices on our spacecraft to let us hear the winds on Titan.

Here is a recording of whistlers recorded by the Van Allen Probes currently orbiting high in the upper atmosphere:

When the computer freezes or the phone battery dies, we complain about how much technology frustrates us and complicates our lives. But our audio technology is also the source of wonder, not only letting us talk to a friend around the world or listen to a podcast from astronauts orbiting the Earth, but letting us listen in on unheard worlds. Ultrasonic microphones let us listen in on bat echolocation and mouse songs, geophones let us wonder at elephants using infrasonic rumbles to communicate long distances and find water. And scientific translation tools let us shift the vibrations of the solar wind and aurora or even the patterns of pure math into human scaled songs of the greater universe. We are no longer constrained (or protected) by the ears that evolution has given us. Our auditory world has expanded into an acoustic ecology that contains the entire universe, and the implications of that remain wonderfully unclear.


Exhibit: Home Office

This is a recording made with standard stereo microphones of my home office. Aside from usual typing, mouse clicking and computer sounds, there are a couple of 3D printers running, some music playing, largely an environment you don’t pay much attention to while you’re working in it, yet acoustically very rich if you pay attention.


This sample was made by pitch shifting the frequencies of sonicoffice.wav down so that the ultrasonic moves into the normal human range and cuts off at about 1-2 kHz as if you were hearing with mouse ears. Sounds normally inaudible, like the squealing of the computer monitor cycling on kick in and the high pitched sound of the stepper motors from the 3D printer suddenly become much louder, while the familiar sounds are mostly gone.


This recording of the office was made with a Clarke Geophone, a seismic microphone used by geologists to pick up underground vibration. It’s primary sensitivity is around 80 Hz, although it’s range is from 0.1 Hz up to about 2 kHz. All you hear in this recording are very low frequency sounds and impacts (footsteps, keyboard strikes, vibration from printers, some fan vibration) that you usually ignore since your ears are not very well tuned to frequencies under 100 Hz.


Finally, this sample was made by pitch shifting the frequencies of infrasonicoffice.wav up as if you had grown to elephantine proportions. Footsteps and computer fan noises (usually almost indetectable at 60 Hz) become loud and tonal, and all the normal pitch of music and computer typing has disappeared aside from the bass. (WARNING: The fan noise is really annoying).


The point is: a space can sound radically different depending on the frequency ranges you hear. Different elements of the acoustic environment pop up depending on the type of recording instrument you use (ultrasonic microphone, regular microphones or geophones) or the size and sensitivity of your ears.
