A composer, inventor and historian of sound and the uncanny – Sarah Angliss’ music reflects her lifelong obsession with defunct technology, faded variety acts and English folklore. In this talk she discusses the practices of training animals to mimic human behaviour, language and song.

This week we caught up with Cennydd Bowles over Skype for a truly fascinating discussion about cross-OS design, the future of wearables, what it means to be a junior vs. senior designer, and why sound design will be the next big trend.
Without all the beeps and chimes, without sonic feedback, all of your modern conveniences would be very hard to use. If a device and its sounds are designed correctly, it creates a special “theater of the mind” that users completely buy into. Electronic things are made to feel mechanical. It’s the feeling of movement, texture and articulation where none exists. We talk with Sound Designer Jim McKee of Earwax Productions about the art of designing organic sounds for inorganic things.

Dramatizing the Internet.
Deep beneath the border of France and Switzerland, the world’s most massive physics machine is sending subatomic particles smashing into each other at speeds nearing the speed of light. Physicists working with the 17-mile-long Large Hadron Collider hope it will help solve some of the universe’s mysteries.
But first, researchers must overcome two very mundane hurdles: how to handle all of the data the LHC generates, and how to get non-scientists to care.
One physicist has a novel way to solve both problems: sound.
"I have some musician friends that I was talking to about physics, which I do a lot, if people will let me, and I was doing impersonations of particles — as you do — or maybe not," Lily Asquith says with a laugh. She is a physicist who until recently worked with the LHC at CERN, the European Organization for Nuclear Research.
Here’s How It Works
The concept underlying the LHC Sound project is a principle called sonification — using data to make sound. At the most basic level, sonification correlates any physical property, such as a distance, speed or direction, to a sound property such as loudness, pitch or duration. On her blog, Lily Asquith explains how to make sound out of anything. The audio clip below is sonified data from the ATLAS detector at the Large Hadron Collider. Here’s how the sound was made: Enlarge image Lily Asquith/LHC Sound Listen To The Data playlist As a beam of particles is fired through the detector, three data points are collected and mapped to sound parameters: (1) The distance the particle travels away from the beam (dR in the diagram above) becomes the sound’s pitch, (2) the amount of energy a particle has correlates to volume, and (3) how far the particle travels becomes the timing of the notes. Asquith, like many physicists, spends a lot of time thinking about particles like the elusive Higgs boson — the subatomic particle that scientists say endows everything in the universe with mass. Proving the existence of the Higgs boson is one of the main goals of the collider.
"You tend to personify things that you think about a lot," she says. She gives particles personalities, colors and sounds. "I think electrons, perhaps, sound like a glockenspiel to me."
In the process of the search for the Higgs, the collider generates a massive amount of information — more than 40 million pieces of data every second. And that’s just from the ATLAS detector, one of the four main detectors in the deep underground complex that tunnels back and forth across the French-Swiss border.
So Asquith was trying to figure out a new way to understand and sort through all of this data. The LHC currently produces colorful images as an output from the data — sprays of particles in different directions.
"It’s quite easy to step from there, really, to consider that there could be some kind of sound associated with these things," she says.
Making Sound From The Data
She thought about a heart monitor in a hospital; it turns the electrical data from your heart into sound.
"You don’t have to watch the monitor because you can hear it without making any effort," she says. "Just a steady beep — you can quite easily detect if it starts going quicker or if it stops even for a second."
She wondered what would happen if she used music composition software to turn data from the collider into sound. So she fed in a sample of the LHC data — three columns of numbers.
"So we’ll map, for example, the first column of numbers, which may be a distance, to time," Asquith says. "And we may map the second column of numbers to pitch, and the third, perhaps, to volume."
What she got isn’t quite music, but sounds that are more out of this world — bells, beeps and clangs.
Interpreting The Sounds
Right now, Asquith says, the sounds don’t tell scientists very much. But she hopes that in the future, it could help them understand the data in new ways.

"You could certainly have an alarm system which told you when, for example, you have an event which looks ridiculous according to what you’ve expected," she says. "And that’s quite difficult to do using your eyes."
But the project is doing something else — making what’s going on at the collider accessible and interesting to people without a Ph.D. That includes many of Lily’s friends who are musicians.
They are really interested in — even fascinated by — what’s going on at the LHC. But she says they start to look frightened when she brings up the hard science.
"I just think that’s unnecessary that it frightens people — it should be something that everyone should enjoy," she says.

We celebrated our one month anniversary a few days ago, so it seemed fitting to run with the very first episode that we produced back when we were kicking around ideas for getting the podcast off the ground. It’s a page out of Kevin’s research on the history of hacker culture, which turns to a meditation on the role of telephony and sound in our world. Enjoy!
The phreak who goes by Mark Bernay is a wonderful and gracious guy for talking with me and for lending me some of his audio to use in this episode. If you want to check out more of his recordings, head over to Phone Trips.

Once long past, listening gave clues for survival. Now we listen unconsciously, blocking noise and tuning in to what we want to hear. Yet the unwanted sounds we filter out tell us a lot about our environment and our lives. Broadcaster Teresa Goff listens for the messages in our walls of sound.
As civilization has become more mechanized, more urbanized and more digitized, the amount of noise has increased in tandem. This noise, according to Garrett Keizer, author of The Unwanted Sound of Everything We Want: A Book about Noise , "is a window for understanding some of the paradoxes and contradictions of being human." If you take the sum total of all sounds within any area, what you have is an intimate reflection of the social, technological, and natural conditions of that place.
Hildegard Westerkamp, a founding member of the World Forum for Acoustic Ecology, says that "Environmental sound is like a spoken word with each sound or soundscape having its own meanings and expressions." So when you listen to the noise, what does it have to tell you? "Noise is a pit of interpretation," says noise musician Brian Chippendale. Broadcaster Teresa Goff goes into the pit with her documentary, The Signal of Noise.
