Macrophones (ongoing)

Normally too low-frequency to hear, infrasound travels vast distances through the atmosphere. It comes from superstorms, wildfires, energy infrastructure, and HVAC systems at massive data centers. Big phenomena like these are entangled with the climate crisis. If we could hear infrasound, could we listen to the crisis as it unfolds all across the globe?

Macrophones appropriates Cold War technology and combines it with cutting-edge signal processing and machine learning in order to make infrasound audible. It comprises large sculptural wind filters situated in locations such as an old-growth forest, the arctic landscape, and urban neighborhoods. By wearing directional, augmented-reality headphones, visitors can hear atmospheric disturbances nearby and thousands of miles away, cultivating the global sensitivity on which an equitable climate future depends.
