Standing Up, For Jose


Round Circle of ResonanceThe following video installation by Mandie O’Connell, is part three of a four part series, “Round Circle of Resonance” by the Berlin based arts collective La Mission that performs connections between the theory of José Esteban Muñoz and sound art/study/theory/performance.

The first installment and second installments ran last Monday.  The opening salvo, written by La Mission’s resident essayist / deranged propagandist LMGM (Luis-Manuel Garcia) provides a brief introduction to our collective, some reflections on Muñoz’s relevance to our activities, and a frame for the next three missives from our fellow cultists. It is backed with a rousing sermon-cum-manifesto from our charismatic cult-leader/prophet, El Jefe (Pablo Roman-Alcalá).  Next Monday, our saucy Choir Boy/Linguist (Johannes Brandis) will close the forum with a dirge to our dearly departed José (August 9, 1967- December, 4, 2013).

Artist’s Statement

Piss is Power.

Power exists in urination, in this basic and most crucial of bodily acts.  Problems with urination can result in embarrassment, infection, hospitalization.  And yet so many of us women encounter confining, unfair, cruel, and Puritan limitations to where, when, and how we can pee, while our male counterparts traipse around urinating wherever they please.  It is time, brothers and sisters, to re-politicize piss.

Brother Muñoz taught us that utopian projects require fellow participants, not audiences. We need a Urinary Utopia, a Piss Paradise that is open to men, women, trans and intersex people of all colors.  Let’s shower down a blissful piss, a rainbow-colored golden shower where we all can piss wherever the fuck we want to!

In my performance video, I attempt to create a Muñoz-inspired utopian sensibility through the enactment of a new modality of an everyday action.  I use a Female Urination Device—which enables me to stand up and urinate—to take a Yellow Adventure around my neighborhood.  I piss freely in places where my penis-having brethren piss.  I piss in a urinal next to which “Piss on me Bitch” is crudely scrawled. I piss into the river Spree, symbolically owning it with my liquid gold.  Finally, I write my name in piss, a macho action turned feminine, the power and privilege of said action redirected towards my vagina.

In “Standing Up,” three different sounds are mixed together to create the soundscape of the performance: ambient noise, music, and sound clips of urination.  The ambient noise serves to locate the scene in space/time.  The music by Khrom Ju was selected to give the performance an eerie, strange, and repetitive undertone.  The sound of urination was recorded live and is the sound of female urination.  We use this sound both as a cue and as comic relief.  Piss is funny, piss is strange, and piss happens all around us.

don't piss

Urination and the female struggle around it is a real struggle that really happens and really matters.  Exceptionally long lines for the ladies’ room, the inability to publically urinate at festivals due to feeling exposed and shamed, being charged money to use toilet facilities when males can piss outdoors for free, getting forced to use a ladies’ room when your sexuality sways towards using the men’s room, the list of complaints goes on and on.  So I say: pee where you want, not where others want you to.  Pee on administrators, police, politicians, and oppressors of all kinds while you’re at it!

I refuse to adhere to these rules anymore, and I beg you to follow my lead.

Piss is Power.

Mandie O’Connell (yo) aka “Knuckle Cartel, is  a former big cheese and intellectual powerhouse behind the wildly successful Seattle-based experimental theater company Implied Violence. I, Mandie, have experienced the same “conservatism” and capitalistic partnership between Money and Art in the performance/theater scene. Witnessing firsthand the immense power that cash-wielding creeps hold over creatives is sickening, sad, and sordid. I’ve had enough, and so have you…right? Let’s fix a broken system. If we can’t fix it, let’s circumvent it.

Someplaces: Radio Art, Transmission Ecology and Chicago’s Radius

This week Sounding Out! is proud to present the first post in Radio Art Reflections, a three part series curated by radio artist and senior radio lecturer at Canterbury Christ Church University Magz Hall. Focusing on innovative approaches to radio art, the series will bring together three leading practitioners who have been researching the field from Canada, Australia and the U.K.

We begin with a fascinating exploration of “transmission ecologies” in recent works in Chicago, Iceland and elsewhere, written by Canadian sound and radio artist Anna Friz — one of the most exciting radio artists working today — who discusses how transmission art has shaped her practice.

– Special Editor Neil Verma

From the early avant-garde Futurists to present-day, utopian dreams litter the history of art meeting technology. When it comes to radio and wireless, these often include the dreams that each new technology will conquer space and time; that the overcoming of distance will enable the symbiosis of human with machine and the union of self with other, while the overcoming of time will bring about a simultaneity of experience. For many radio and transmission artists (myself included), our work with so-called “trailing edge” media seeks to critically engage these myths, positing wireless transmissions instead as time-based, site-specific encounters between people and devices over distances small or large, where the materiality of the electro-magnetic spectrum is experienced within a constantly shifting transmission ecology in which we all, people and devices, function.

If one hallmark of radio art is the desire to appropriate broadcasting by rethinking and re-using technologies of transmission and reception in service of crafting new mythologies and futures for the medium. Artists have long questioned the policies and norms established by state and market around radio broadcasting which delimit experimentation and autonomous practices. Bertolt Brecht‘s call in 1932 for radio to exceed its one-to-many broadcast format in favor of a democratized, transceptive (or many-to-many) medium still resonates with contemporary artists and activists alike. What else could radio become, we ask, if not only a disseminator of information and entertainment, acoustic or digital? If radio so far has largely acted as an accomplice in the industrialization of communications, artistic appropriations of radio can destabilize this process with renewed explorations of radio and electromagnetic phenomena, constructions of temporary networks small or large, and radical explorations of broadcast beyond the confines of programming and format norms.

Curators, producers and art historians typically describe radio art as the use of radio as an artistic medium, which is to say, art created specifically for the technical and cultural circumstances of broadcast, and which considers these circumstances as artistic material. Today these circumstances have exceeded terrestrial broadcast to include satellite, online, and on-demand forms; similarly radio art has also expanded to include sprawling telematic art exchanges, online podcast series, and unlicensed temporary interventions into the radio dial. As a further reclamation of radio as a medium, many artists pull radio out of the studio to create installations, performance works and public actions which consider not just the act of transmission or the creation of artistic content, but also the material aspects of the electro-magnetic spectrum, and the circuits of people and devices which activate and reveal them.

Japanese media theorist and artist Tetsuo Kogawa describes broadcast radio art as art radio, where art is the content of a transmission. By contrast, radio art involves directly playing with electro-magnetic waves as the artistic medium. Galen Joseph-Hunter of Wave Farm further expands Kogawa’s formulation of radio art with the term transmission art, so as to include audio visual broadcast media and artistic activities across the entire electro-magnetic spectrum, such as work with Very Low Frequency (VLF) and Extremely Low Frequency (ELF) waves, or high frequency wireless networks. These definitions of radio and transmission art emphasize that radio is not a container for content, but is defined as relationships between people and things, occurring in the context of the electro-magnetic spectrum within a transmission ecology.

I apply the term transmission ecology in reference to both the symbolic spaces of cultural production such as a radio station, and to the invisible but very material space of dynamic electromagnetic interactions, both of which feature the collaboration between people and things. Transmission ecology asks more than “who owns the airwaves” by questioning the shifting relationships between all actors in the environment, from human to device to localized weather system to nearby star, and thus is not defined by homeostasis but by constant change. These relationships also support a theory of technology where people are not the absolute controllers of things, but where a push and pull of collaboration occurs within complex material and cultural environments.

All activities in the electro-magnetic spectrum form ecologies in relation to one another conceptually, performatively, and materially. Consider the Radia network, an international alliance of independent radio stations who share radio art programming as an alternate transmission ecology within the broader culture of private broadcast radio stations. Another kind of ecology is formed by radio receivers all playing the same station diffused across countless cars and households, as they function in relation to other kinds of wireless devices and electronic systems nearby. Such a muster of receivers can be physically brought together, for instance, in a multi-channel radio installation, to reveal the complex relationships among devices, as each receiver also becomes a sender by electronically effecting its neighbor. A mobile phone receiving wireless internet likewise functions within the instability inherent in the surrounding transmission ecology shaped by all aspects of the built environment, such as the electrical grid and other urban infrastructure, as well as weather or time of day or solar flares. Human bodies and devices alike register the invisible electromagnetic activity that surrounds us as physical, measurable, and affective.

With this in mind consider radio art as occupying “radio space,” a continuous, available, fluctuating area described by the reach of signals within overlapping fields of influence and the space of imagination that invisible territory enables. The extrasensory nature of radio space allows for a productive slippage between real material signals and audible imaginary landscapes. Many radio art and transmission art works specifically draw attention to the transmission ecology in order to question the naturalization of mainstream communications systems, the normalization of practices within those systems, and the pervasiveness of electrical infrastructure, proposing alternate narratives and experiences.

So what is some of this work like? In the past year I have had the pleasure to work with Chicago-based Radius, an experimental radio-based platform which curates monthly episodes broadcast locally using the Audio Relay Unit, an unlicensed autonomous low-watt FM radio transmitter system developed in 2002 by Temporary Services and the Intermod Series. Radius neatly unites radio and transmission art by embracing the production of artistic content for broadcast, sampling existing content for artistic expression, and artistic use of the electro-magnetic spectrum generally. Radius functions as an intermittent exhibition space and as an intervention into the predictable daily grind of the FM dial. Artists compose their pieces specifically for the interference-prone radio space where their work may only be heard in fragments, as the instability and fluctuations of the relatively small Radius signal in relation to the big commercial stations broadcasting from downtown all form the context for experiencing the radio art works. Radius broadcasts one episode per month, on a schedule determined by the artist, with pieces varying in length and repetition, and some following a strict schedule related to cosmic or social timing.

Recently I crafted an episode for Radius while on an artist residency in Seydisfjördur, Iceland. The town was the site of the first trans-Atlantic telegraph link between Europe and Iceland in 1906, which was also the year that Reginald Fessenden first broadcast a human voice over radio from his workshop in Brant Rock, Massachusetts. Iceland is remote enough that the electro-magnetic ‘pollution’ from human signal activity is notably absent, and located far enough to the north that in October the light disappears rapidly, so that each day loses eight minutes of daylight. The piece was called Radiotelegraph, a beacon crafted from spoken morse code and sampled signals, then sent from north to south, simulcast on my own low-watt FM transmitter in Seydisfjördur at sundown each day as well as on Radius in Chicago. The transmission marked time passing, beginning earlier each day as it followed the path of the sun. My intention was not to overcome but to experience and recuperate distance through the relation of a remote radio outpost to another minor outpost further south within a metropolis; to hear distance and feel it; to understand that distance, however finite, is a necessary condition for communication and relationship, and that distance is the key ingredient of situated, time-based, spatialized sonic experiences.

Here is the Radius episode featuring Radiotelegraph:

As part of a recent yearly theme on “Grids” Radius tackled the electro-magnetic field space of the city by inviting four artists to create new works to be performed near power stations. In his piece electrosmog, Canadian artist Kristen Roos utilized a high frequency receiver to sonify signal activity in the 800 MHz – 2.5 GHz range, which includes mobile phones, wireless phones, wifi, and microwaves. His site-specific performance took place overlooking the Fisk Generating Station in Chicago, and included microwave ovens and micro-watt transmission to a sound system made of radio receivers. Thus the work was site-specific to both the transmission ecology of urban Chicago and the field effects of the electrical grid, mixing material signals with a speculative approach as to what the cumulative effects of living in this built environment characterized by centralized power could be. In Roos’ work, radio space contextualized and revealed the real–though naturalized and often invisible–relationships between people, things, and systems, where a microwave oven gestured at both danger and musicality.

Listen to the Roos piece here:

These radio art works enact places in radiophonic space, and experiment with transmission to question the status quo of how the airwaves are controlled and used. As radio trickster Gregory Whitehead notes, it is position, not sound, that matters most with regard to radio. Artists remain committed to making radiophonic someplaces, however temporarily constructed, inhabited by interpenetrating and overlapping fields and bodies.

Acousmatic Surveillance and Big Data


Sound and Surveilance4

It’s an all too familiar movie trope. A bug hidden in a flower jar. A figure in shadows crouched listening at a door. The tape recording that no one knew existed, revealed at the most decisive of moments. Even the abrupt disconnection of a phone call manages to arouse the suspicion that we are never as alone as we may think. And although surveillance derives its meaning the latin “vigilare” (to watch) and French “sur-“ (over), its deep connotations of listening have all but obliterated that distinction.

Moving on from cybernetic games to modes of surveillance that work through composition and patterns. Here, Robin James challenges us to consider the unfamiliar resonances produced by our IP addresses, search histories, credit trails, and Facebook posts. How does the NSA transform our data footprints into the sweet, sweet, music of surveillance? Shhhhhhhh! Let’s listen in. . . -AT

Kate Crawford has argued that there’s a “big metaphor gap in how we describe algorithmic filtering.” Specifically, its “emergent qualities” are particularly difficult to capture. This process, algorithmic dataveillance, finds and tracks dynamic patterns of relationships amongst otherwise unrelated material. I think that acoustics can fill the metaphor gap Crawford identifies. Because of its focus on identifying emergent patterns within a structure of data, rather than its cause or source, algorithmic dataveillance isn’t panoptic, but acousmatic. Algorithmic dataveillance is acousmatic because it does not observe identifiable subjects, but ambient data environments, and it “listens” for harmonics to emerge as variously-combined data points fall into and out of phase/statistical correlation.

Dataveillance defines the form of surveillance that saturates our consumer information society. As this promotional Intel video explains, big data transcends the limits of human perception and cognition – it sees connections we cannot. And, as is the case with all superpowers, this is both a blessing and a curse. Although I appreciate emails from my local supermarket that remind me when my favorite bottle of wine is on sale, data profiling can have much more drastic and far-reaching effects. As Frank Pasquale has argued, big data can determine access to important resources like jobs and housing, often in ways that reinforce and deepen social inequities. Dataveillance is an increasingly prominent and powerful tool that determines many of our social relationships.

The term dataveillance was coined in 1988 by Roger Clarke, and refers to “the systematic use of personal data systems in the investigation or monitoring of the actions or communications of one or more persons.” In this context, the person is the object of surveillance and data is the medium through which that surveillance occurs. Writing 20 years later, Michael Zimmer identifies a phase-shift in dataveillance that coincides with the increased popularity and dominance of “user-generated and user-driven Web technologies” (2008). These technologies, found today in big social media, “represent a new and powerful ‘infrastructure of dataveillance,’ which brings about a new kind of panoptic gaze of both users’ online and even their offline activities” (Zimmer 2007). Metadataveillance and algorithmic filtering, however, are not variations on panopticism, but practices modeled—both historically/technologically and metaphorically—on acoustics.

In 2013, Edward Snowden’s infamous leaks revealed the nuts and bolts of the National Security Administration’s massive dataveillance program. They were collecting data records that, according to the Washington Post, included “e-mails, attachments, address books, calendars, files stored in the cloud, text or audio or video chats and ‘metadata’ that identify the locations, devices used and other information about a target.” The most enduringly controversial aspect of NSA dataveillance programs has been the bulk collection of Americans’ data and metadata—in other words, the “big data”-veillance programs.

Instead of intercepting only the communications of known suspects, this big dataveillance collects everything from everyone and mines that data for patterns of suspicious behavior; patterns that are consistent with what algorithms have identified as, say, “terrorism.” As Cory Doctorow writes in BoingBoing, “Since the start of the Snowden story in 2013, the NSA has stressed that while it may intercept nearly every Internet user’s communications, it only ‘targets’ a small fraction of those, whose traffic patterns reveal some basis for suspicion.” “Suspicion,” here, is an emergent property of the dataset, a pattern or signal that becomes legible when you filter communication (meta)data through algorithms designed to hear that signal amidst all the noise.

Hearing a signal from amidst the noise, however, is not sufficient to consider surveillance acousmatic. “Panoptic” modes of listening and hearing, though epitomized by the universal and internalized gaze of the guards in the tower, might also be understood as the universal and internalized ear of the confessor. This is the ear that, for example, listens for conformity between bodily and vocal gender presentation. It is also the ear of audio scrobbling, which, as Calum Marsh has argued, is a confessional, panoptic music listening practice.

Therefore, when President Obama argued that “nobody is listening to your telephone calls,” he was correct. But only insofar as nobody (human or AI) is “listening” in the panoptic sense. The NSA does not listen for the “confessions” of already-identified subjects. For example, this court order to Verizon doesn’t demand recordings of the audio content of the calls, just the metadata. Again, the Washington Post explains:

The data doesn’t include the speech in a phone call or words in an email, but includes almost everything else, including the model of the phone and the “to” and “from” lines in emails. By tracing metadata, investigators can pinpoint a suspect’s location to specific floors of buildings. They can electronically map a person’s contacts, and their contacts’ contacts.

NSA dataveillance listens acousmatically because it hears the patterns of relationships that emerge from various combinations of data—e.g., which people talk and/or meet where and with what regularity. Instead of listening to identifiable subjects, the NSA identifies and tracks emergent properties that are statistically similar to already-identified patterns of “suspicious” behavior. Legally, the NSA is not required to identify a specific subject to surveil; instead they listen for patterns in the ambience. This type of observation is “acousmatic” in the sound studies sense because the sounds/patterns don’t come from one identifiable cause; they are the emergent properties of an aggregate.

Acousmatic listening is a particularly appropriate metaphor for NSA-style dataveillance because the emergent properties (or patterns) of metadata are comparable to harmonics or partials of sound, the resonant frequencies that emerge from a specific combination of primary tones and overtones. If data is like a sound’s primary tone, metadata is its overtones. When two or more tones sound simultaneously, harmonics emerge whhen overtones vibrate with and against one another. In Western music theory, something sounds dissonant and/or out of tune when the harmonics don’t vibrate synchronously or proportionally. Similarly, tones that are perfectly in tune sometimes create a consonant harmonic. The NSA is listening for harmonics. They seek metadata that statistically correlates to a pattern (such as “terrorism”), or is suspiciously out of correlation with a pattern (such as US “citizenship”). Instead of listening to identifiable sources of data, the NSA listens for correlations among data.

Both panopticism and acousmaticism are technologies that incite behavior and compel people to act in certain ways. However, they both use different methods, which, in turn, incite different behavioral outcomes. Panopticism maximizes efficiency and productivity by compelling conformity to a standard or norm. According to Michel Foucault, the outcome of panoptic surveillance is a society where everyone synchs to an “obligatory rhythm imposed from the outside” (151-2), such as the rhythmic divisions of the clock (150). In other words, panopticism transforms people into interchangeable cogs in an industrial machine.  Methodologically, panopticism demands self-monitoring. Foucault emphasizes that panopticism functions most efficiently when the gaze is internalized, when one “assumes responsibility for the constraints of power” and “makes them play…upon himself” (202). Panopticism requires individuals to synchronize themselves with established compulsory patterns.

Acousmaticism, on the other hand, aims for dynamic attunement between subjects and institutions, an attunement that is monitored and maintained by a third party (in this example, the algorithm). For example, Facebook’s News Feed algorithm facilitates the mutual adaptation of norms to subjects and subjects to norms. Facebook doesn’t care what you like; instead it seeks to transform your online behavior into a form of efficient digital labor. In order to do this, Facebook must adjust, in part, to you. Methodologically, this dynamic attunement is not a practice of internalization, but unlike Foucault’s panopticon, big dataveillance leverages outsourcing and distribution. There is so much data that no one individual—indeed, no one computer—can process it efficiently and intelligibly. The work of dataveillance is distributed across populations, networks, and institutions, and the surveilled “subject” emerges from that work (for example, Rob Horning’s concept of the “data self”). Acousmaticism tunes into the rhythmic patterns that synch up with and amplify its cycles of social, political, and economic reproduction.

Unlike panopticism, which uses disciplinary techniques to eliminate noise, acousmaticism uses biopolitical techniques to allow profitable signals to emerge as clearly and frictionlessly as possible amid all the noise (for more on the relation between sound and biopolitics, see my previous SO! essay). Acousmaticism and panopticism are analytically discrete, yet applied in concert. For example, certain tiers of the North Carolina state employee’s health plan require so-called “obese” and tobacco-using members to commit to weight-loss and smoking-cessation programs. If these members are to remain eligible for their selected level of coverage, they must track and report their program-related activities (such as exercise). People who exhibit patterns of behavior that are statistically risky and unprofitable for the insurance company are subject to extra layers of surveillance and discipline. Here, acousmatic techniques regulate the distribution and intensity of panoptic surveillance. To use Nathan Jurgenson’s turn of phrase, acousmaticism determines “for whom” the panoptic gaze matters. To be clear, acousmaticism does not replace panopticism; my claim is more modest. Acousmaticism is an accurate and productive metaphor for theorizing both the aims and methods of big dataveillance, which is, itself, one instrument in today’s broader surveillance ensemble.

Sounds of Science: The Mystique of Sonification


Hearing the Unheard IIWelcome to the final installment of Hearing the UnHeardSounding Out!s series on what we don’t hear and how this unheard world affects us. The series started out with my post on hearing, large and small, continued with a piece by China Blue on the sounds of catastrophic impacts, and Milton Garcés piece on the infrasonic world of volcanoes. To cap it all off, we introduce The Sounds of Science by professor, cellist and interactive media expert, Margaret Schedel.

Dr. Schedel is an Associate Professor of Composition and Computer Music at Stony Brook University. Through her work, she explores the relatively new field of Data Sonification, generating new ways to perceive and interact with information through the use of sound. While everyone is familiar with informatics, graphs and images used to convey complex information, her work explores how we can expand our understanding of even complex scientific information by using our fastest and most emotionally compelling sense, hearing.

– Guest Editor Seth Horowitz

With the invention of digital sound, the number of scientific experiments using sound has skyrocketed in the 21st century, and as Sounding Out! readers know, sonification has started to enter the public consciousness as a new and refreshing alternative modality for exploring and understanding many kinds of datasets emerging from research into everything from deep space to the underground. We seem to be in a moment in which “science that sounds” has a special magic, a mystique that relies to some extent on misunderstandings in popular awareness about the processes and potentials of that alternative modality.

For one thing, using sound to understand scientific phenomena is not actually new. Diarist Samuel Pepys wrote about meeting scientist Robert Hooke in 1666 that “he is able to tell how many strokes a fly makes with her wings (those flies that hum in their flying) by the note that it answers to in musique during their flying.” Unfortunately Hooke never published his findings, leading researchers to speculate on his methods. One popular theory is that he tied strings of varying lengths between a fly and an ear trumpet, recognizing that sympathetic resonance would cause the correct length string to vibrate, thus allowing him to calculate the frequency. Even Galileo used sound, showing the constant acceleration of a ball due to gravity by using an inclined plane with thin moveable frets. By moving the placement of the frets until the clicks created an even tempo he was able to come up with a mathematical equation to describe how time and distance relate when an object falls.

There have also been other scientific advances using sound in the more recent past. The stethoscope was invented in 1816 for auscultation, listening to the sounds of the body. It was later applied to machines—listening for the operation of the technological gear. Underwater sonar was patented in 1913 and is still used to navigate and communicate using hydroacoustic phenomenon. The Geiger Counter was developed in 1928 using principles discovered in 1908; it is unclear exactly when the distinctive sound was added. These are all examples of auditory display [AD]; sonification-generating or manipulating sound by using data is a subset of AD. As the forward to the The Sonification Handbook states, “[Since 1992] Technologies that support AD have matured. AD has been integrated into significant (read “funded” and “respectable”) research initiatives. Some forward thinking universities and research centers have established ongoing AD programs. And the great need to involve the entire human perceptual system in understanding complex data, monitoring processes, and providing effective interfaces has persisted and increased” (Thomas Hermann, Andy Hunt, John G. Neuhoff, Sonification Handbook, iii)

Sonification clearly enables scientists, musicians and the public to interact with data in a very different way, particularly compared to the more numerous techniques involving vision. Indeed, because hearing functions quite differently than vision, sonification offers an alternative kind of understanding of data (sometimes more accurate), which would not be possible using eyes alone. Hearing is multi-directional—our ears don’t have to be pointing at a sound source in order to sense it. Furthermore, the frequency response of our hearing is thousands of times more accurate than our vision. In order to reproduce a moving image the sampling rate (called frame-rate) for film is 24 frames per second, while audio has to be sampled at 44,100 frames per second in order to accurately reproduce sound. In addition, aural perception works on simultaneous time scales—we can take in multiple streams of audio data at once at many different dynamics, while our pupils dilate and contract, limiting how much visual data we can absorb at a single time. Our ears are also amazing at detecting regular patterns over time in data; we hear these patterns as frequency, harmonic relationships, and timbre.

But hearing isn’t simple, either. In the current fascination with sonification, the fact that aesthetic decisions must be made in order to translate data into the auditory domain can be obscured. Headlines such as “Here’s What the Higgs Boson Sounds Like” are much sexier than headlines such as “Here is What One Possible Mapping of Some of the Data We Have Collected from a Scientific Measuring Instrument (which itself has inaccuracies) Into Sound.” To illustrate the complexity of these aesthetic decisions, which are always interior to the sonification process, I focus here on how my collaborators and I have been using sound to understand many kinds of scientific data.

My husband, Kevin Yager, a staff scientist at Brookhaven National Laboratory, works at the Center for Functional Nanomaterials using scattering data from x-rays to probe the structure of matter. One night I asked him how exactly the science of x-ray scattering works. He explained that X-rays “scatter” off of all the atoms/particles in the sample and the intensity is measured by a detector. He can then calculate the structure of the material, using the Fast Fourier Transform (FFT) algorithm. He started to explain FFT to me, but I interrupted him because I use FFT all the time in computer music. The same algorithm he uses to determine the structure of matter, musicians use to separate frequency content from time. When I was researching this post, I found a site for computer music which actually discusses x-ray scattering as a precursor for FFT used in sonic applications.

To date, most sonifications have used data which changes over time – a fly’s wings flapping, a heartbeat, a radiation signature. Except in special cases Kevin’s data does not exist in time – it is a single snapshot. But because data from x-ray scattering is a Fourier Transform of the real-space density distribution, we could use additive synthesis, using multiple simultaneous sine waves, to represent different spatial modes. Using this method, we swept through his data radially, like a clock hand, making timbre-based sonifications from the data by synthesizing sine waves using with the loudness based on the intensity of the scattering data and frequency based on the position.

We played a lot with the settings of the additive synthesis, including the length of the sound, the highest frequency and even the number of frequency bins (going back to the clock metaphor – pretend the clock hand is a ruler – the number of frequency bins would be the number of demarcations on the ruler) arriving eventually at set of optimized variables.

Here is one version of the track we created using 10 frequency bins:


Here is one we created using 2000:


And here is one we created using 50 frequency bins, which we settled on:


On a software synthesizer this would be like the default setting. In the future we hope to have an interactive graphic user interface where sliders control these variables, just like a musician tweaks the sound of a synth, so scientists can bring out, or mask aspects of the data.

To hear what that would be like, here are a few tracks that vary length:




Finally, here is a track we created using different mappings of frequency and intensity:


Having these sliders would reinforce to the scientists that we are not creating “the sound of a metallic alloy,” we are creating one sonic representation of the data from the metallic alloy.

It is interesting that such a representation can be vital to scientists. At first, my husband went along with this sonification project as more of a thought experiment rather than something that he thought would actually be useful in the lab, until he heard something distinct about one of those sounds, suggesting that there was a misaligned sample. Once Kevin heard that glitched sound (you can hear it in the video above), he was convinced that sonification was a useful tool for his lab. He and his colleagues are dealing with measurements 1/25,000th the width of a human hair, aiming an X-ray through twenty pieces of equipment to get the beam focused just right. If any piece of equipment is out of kilter, the data can’t be collected. This is where our ears’ non-directionality is useful. The scientist can be working on his/her computer and, using ambient sound, know when a sample is misaligned.


It remains to be seen/heard if the sonifications will be useful to actually understand the material structures. We are currently running an experiment using Mechanical Turk to determine this kind of multi-modal display (using vision and audio) is actually helpful. Basically we are training people on just the images of the scattering data, and testing how well they do, and training another group of people on the images plus the sonification and testing how well they do.

I’m also working with collaborators at Stony Brook University on sonification of data. In one experiment we are using ambisonic (3-dimensional) sound to create a sonic map of the brain to understand drug addiction. Standing in the middle of the ambisonic cube, we hope to find relationships between voxels, a cube of brain tissue—analogous to pixels. When neurons fire in areas of the brain simultaneously there is most likely a causal relationship which can help scientists decode the brain activity of addiction. Computer vision researchers have been searching for these relationships unsuccessfully; we hope that our sonification will allow us to hear associations in distinct parts of the brain which are not easily recognized with sight. We are hoping to leverage the temporal pattern recognition of our auditory system, but we have been running into problems doing the sonification; each slice of data from the FMRI has about 300,000 data points. We have it working with 3,000 data points, but either our programming needs to get more efficient, or we have to get a much more powerful computer in order to work with all of the data.

On another project we are hoping to sonify gait data using smartphones. I’m working with some of my music students and a professor of Physical Therapy, Lisa Muratori, who works on understanding the underlying mechanisms of mobility problems in Parkinsons’ Disease (PD). The physical therapy lab has a digital motion-capture system and a split-belt treadmill for asymmetric stepping—the patients are supported by a harness so they don’t fall. PD is a progressive nervous system disorder characterized by slow movement, rigidity, tremor, and postural instability. Because of degeneration of specific areas of the brain, individuals with PD have difficulty using internally driven cues to initiate and drive movement. However, many studies have demonstrated an almost normal movement pattern when persons with PD are provided external cues, including significant improvements in gait with rhythmic auditory cueing. So far the research with PD and sound has be unidirectional – the patients listen to sound and try to match their gait to the external rhythms from the auditory cues.In our system we will use bio-feedback to sonify data from sensors the patients will wear and feed error messages back to the patient through music. Eventually we hope that patients will be able to adjust their gait by listening to self-generated musical distortions on a smartphone.

As sonification becomes more prevalent, it is important to understand that aesthetic decisions are inevitable and even essential in every kind of data representation. We are so accustomed to looking at visual representations of information—from maps to pie charts—that we may forget that these are also arbitrary transcodings. Even a photograph is not an unambiguous record of reality; the mechanics of the camera and artistic choices of the photographer control the representation. So too, in sonification, do we have considerable latitude. Rather than view these ambiguities as a nuisance, we should embrace them as a freedom that allows us to highlight salient features, or uncover previously invisible patterns.
