Listen to Earth’s rumbling, secret soundtrack | MIT Technology Review

You need to enable JavaScript to view this site. Skip to Content The boom of a calving glacier. The crackling rumble of a wildfire. The roar of a surging storm front. They’re the noises of the living Earth, music of this one particular sphere and clues to the true nature of these dramatic events. But as loud as all these things are, they emit even more acoustic energy below the threshold of human hearing, at frequencies of 20 hertz or lower. These “infrasounds” have such long wavelengths that they can travel around the globe as churning emanations of distant events. But humans have never been able to hear them.

Everyday Infrasound in an Uncertain World, a new album by the musician and artist Brian House, condenses 24 hours of these rumbles into 24 minutes of the most basic of bass lines, putting a new spin on the idea of ambient music. Sound, even infrasound, is really just variations in air pressure. So House built a set of three “macrophones,” tubes that funnel air into a barometer capable of taking readings 100 times a second. From the quiet woods of western Massachusetts, House can pick up what the planet is laying down. Then he speeds the recording up by a factor of 60 so that it’s audible to the wee ears of humans. “I am really interested in the layers of perception that we can’t access,” he says. “It’s not only low sound, but it’s also distant sound. That kind of blew my mind.” House’s album is art, but scientists made it possible. Barometers picked up the 1883 eruption of the South Pacific volcano Krakatoa as far away as London. And today, a global network of infrasound sensors helps enforce the nuclear test ban treaty. A few infrasound experts—like Leif Karlstrom, a volcanologist at the University of Oregon who uses infrasound to study Mount Kilauea in Hawaii—helped House set up his music-gathering array and better understand what he was hearing. “He’s highlighting interesting phenomena,” Karlstrom says, even though it’s impossible to tell exactly what is making each specific sound.  So how’s the actual music? It’s 24 minutes of an otherworldly chorus, alternating between low grumbling vibrations and soft ghostlike whispers. A high-pitched whistle? Could be a train, House says. An intense low-octave rattle? Maybe a distant thunderstorm or a shifting ocean current. “For me, it’s about the mystery of it,” he says. “I hope that’s a little bit unsettling.” But it also might connect someone listening to a wider—and deeper—world.  Monique Brouillette is a freelance writer based in Cambridge, Massachusetts.
