Scientists have discovered that even small grass fires make audible infrasound — low-frequency rumbles detectable by specialized microphones. In a groundbreaking Idaho study, over 90 sensors tracked a controlled burn with minimal intensity, proving the technique works across varied fire conditions. Unlike visual methods blocked by clouds or trees, infrasound lets us “hear” fires invisibly, pinpointing their location using sound arrays and computer analysis. While real wildfires pose greater challenges — including wind interference — this tech could revolutionize early detection. Researchers…
