Normally too low-frequency to hear, infrasound travels vast distances through the atmosphere. It comes from calving glaciers, power plants, wildfires, and even 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 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. Situated in locations including old-growth forests, the arctic tundra, and city centers, the installation comprises electronics that record microbarometric fluctuations through a sculptural wind filter. The recordings are processed and resampled upward into an acoustic range that we can hear, and via audio augmented reality, listeners at the site hear infrasound spatially situated in the landscape around them.

Paying attention to how we are connected through the atmosphere, rather than through the internet, is both poetic and political. My hope is that listening to infrasound from nearby and from thousands of miles away can cultivate the expanded sense of the local on which an equitable climate future depends.

可聴域以下の音 (infrasond — 大気中を微気圧振動として伝播する、人間の可聴域以下の低周波の音波。ふつう微気圧計でとらえられる。可聴域の音波と異なり、空気分子の粘性による減衰が小さく、地球規模で伝播することが知られている)を特殊なマイクで拾って可聴域に変換。地球規模での環境の変化を捉えるか。
