Listen to Earth’s rumbling, secret soundtrack

In the vast, living symphony of our planet, the Earth sings in a language few can hear. From the thunderous boom of a calving glacier to the crackling rumble of a wildfire, and the roar of a surging storm front, these are the unmistakable sounds of a dynamic world in motion. Yet, beyond the reach of human ears lies an even deeper layer of this planetary music—infrasound. These are the ultra-low-frequency rumbles, below 20 hertz, that travel vast distances, sometimes circling the globe as echoes of distant events. For centuries, these sounds remained a mystery, inaudible to us. But now, thanks to the innovative work of musician and artist Brian House, we can finally listen in.

House’s groundbreaking album, Everyday Infrasound in an Uncertain World, transforms 24 hours of Earth’s hidden rumblings into a 24-minute auditory journey. By compressing the infrasound data by a factor of 60, House makes these otherwise imperceptible vibrations audible to human ears. The result is a hauntingly beautiful piece of ambient music that invites listeners to experience the planet in a way never before possible.

The magic behind this project lies in House’s custom-built “macrophones”—tubes that channel air into a highly sensitive barometer capable of taking 100 readings per second. Positioned in the quiet woods of western Massachusetts, these devices capture the Earth’s infrasonic whispers, from the distant rumble of ocean currents to the subtle shifts of the atmosphere. “I am really interested in the layers of perception that we can’t access,” House explains. “It’s not only low sound, but it’s also distant sound. That kind of blew my mind.”

While House’s work is undeniably artistic, it builds on a foundation of scientific discovery. Infrasound has long been a tool for researchers. In 1883, barometers recorded the eruption of the Krakatoa volcano in the South Pacific as far away as London. Today, a global network of infrasound sensors monitors the planet, helping enforce the nuclear test ban treaty and providing insights into natural phenomena like volcanic eruptions and storms. Volcanologist Leif Karlstrom of the University of Oregon, who uses infrasound to study Hawaii’s Mount Kilauea, assisted House in setting up his array and interpreting the data. “He’s highlighting interesting phenomena,” Karlstrom notes, though pinpointing the exact source of each sound remains a challenge.

So, what does this otherworldly music actually sound like? The 24-minute album is a mesmerizing blend of low, grumbling vibrations and soft, ghostly whispers. At times, a high-pitched whistle might evoke the distant whistle of a train. At others, an intense low-octave rattle could be the rumble of a thunderstorm or the shifting of ocean currents. “For me, it’s about the mystery of it,” House says. “I hope that’s a little bit unsettling.” Yet, there’s also a profound beauty in this connection to the planet’s hidden rhythms, a reminder of the vast, unseen forces that shape our world.

House’s work is more than just an artistic experiment; it’s an invitation to listen more deeply to the Earth. In a time of environmental uncertainty, Everyday Infrasound in an Uncertain World offers a unique perspective on the planet’s vitality and fragility. It’s a reminder that, even in the quietest moments, the Earth is alive with sound—if only we know how to listen.
