CERN artist-in-residence develops ear for physics

CERN artist-in-residence develops ear for physics

Sound artist Bill Fontana taps into the music of the Large Hadron Collider.

When Bill Fontana visits a cafe, he’s one of many customers wearing headphones. To a casual observer, he looks like someone in his own private world, cut off from the life around him.

In fact, it’s the opposite: Tiny, sensitive microphones are amplifying the sounds of the cafe—the clatter of dishes in the kitchen, the laughter of the people at the table next to him, the espresso machine hissing and bubbling—and pumping them into his ears.

Fontana devotes his life to capturing and treasuring the music of the moment.

It was in this spirit that he applied for the Prix Ars Electronica Collide@CERN award, for which a digital artist receives a monetary prize and a three-month residency made possible through a collaboration between CERN and international cyberarts organization Ars Electronica with funding from external private donors.

Fontana, 66, grew up in Cleveland, Ohio, in walking distance from the Cleveland Orchestra. He composed music in the 1960s, and began creating his first pieces of audio art in 1976. For the past three decades, his artistic palette has been the latent sounds of the world. 

“Music is continuous; it’s listening that’s intermittent,” Fontana says. “I knew that it was up to me to start recognizing patterns in the sounds around me, so I began listening as a way to make music.”

Fontana creates sound sculptures—installations using microphones and speakers set up in museums and monuments—that transmit sounds from faraway places into new environments.

When he’s working, Fontana carts around a suitcase full of sound gadgets and gizmos. But his primary tool is a device called an accelerometer. Engineers use accelerometers to measure vibrations in solid structures, and Fontana uses them as a way to expand his hearing.

“It’s like an acoustic spaceship,” Fontana says. “By attaching them to a pipe or a steel cable, I can travel inside that object and listen to what it sounds like within.”

He’s plugged his extendable-ear into objects all over the world, like San Francisco’s Golden Gate Bridge and the Arc De Triomphe in Paris, as well as more obscure structures like a crane in Glasgow, a wharf in Sydney and a giant bell at a Buddhist Temple in Kyoto.

“Bill exhibited audacious humility,” says Ariane Koek, CERN cultural specialist and the creator of Collide@CERN, an experiment that brings together art and science. “He’s a well-known artist at the height of his career who demonstrates a willingness to plunge into the unknown.”

Fontana got the gig.

“I think they like the idea of an old-timer like me,” he says.

Dance-club proton

For someone with the knack for hearing music in machinery, the CERN complex is a veritable playground of sound.

Fontana heard the first strains of the Large Hadron Collider’s music in January 2013 when he made a four-day introductory visit. Koek, who managed the visit, recalls Fontana’s giddy enthusiasm. His first question: “What’s this machine and can I listen to it?”

The LHC is currently undergoing repairs, but when Fontana visited for the first time, it was still running, whirring, banging and buzzing.

During the whirlwind introduction, Fontana spent some time at the starting point of the LHC. There, atoms of hydrogen are stripped of their electrons so only positively charged protons remain. An electric field begins to accelerate the protons while a series of magnets focus them into a beam.

Fontana recorded the sounds. The popping, tapping dance beat of the protons’ regular release is underlaid with the hiss of cooling water and the heavy clang of the magnets charging and discharging. 

According to Koek, Fontana listened to the proton source for a moment, and then handed his headphones to Detlef Kuchler, the physicist who prepares the protons and launches them on their journey. Kuchler has run the machine for 15 years, starting when it was a component of the accelerator that preceded the LHC.

When Fontana slipped headphones over Kuchler’s ears, his eyes widened, and he laughed, Koek recalls with a smile.

“The picture on Detlef’s face was astounding,” she says. “This was his baby—and it looked as if he had just heard it crying for the first time.”

Acoustic Time Travel

When Fontana returned to CERN at the beginning of July, he began working on his yet-to-be-revealed centerpiece sculpture, “Acoustic Time Travel.”

“Yes, it sounds like the title of a science fiction movie,” Fontana admits.

He’s broadcasting the recording of the proton-source beat through various structures around CERN and within the LHC tunnel to discover how different materials affect the sound.

The final sound sculpture will be made public in the coming months, but in the meantime, Fontana listens to the LHC with relish.

“Every sound we experience in daily life is a description of the space it inhabits,” Fontana says. “I consider it a privilege to hear the rhythm of all these incredible machines.”
